Non-Mammal Mammaries
aka: Non Mammalian Mammaries

"I dunno, there's something about the combination of beaks and feathers with some distinctly, er, mammalian characteristics that just utterly squicks me out."
The Comics Curmudgeon, in reference to the comic strip Shoe

Look closely at a female reptile, a female amphibian, a female bird, a female fish, a female insect, or most non-primate mammals. You'll doubtless notice the lack of a particular characteristic that is common to female humans. Most animals do not have human-like breasts at all, even if they fall into the category "mammal". Compare the bellies of a male and female dog, or even the chest of a female gorilla, and you won't find much difference unless she's recently given birth to a litter and is nursing young (that's about the only time she will ever have any vague semblance of what we call "breasts" on humans). Both the size and position of human breasts are likely the results of bipedalism— or more likely, the longer infancy-period of humans in relation to other animals (see "female gorilla" above).

Regardless of this, artists tend to oversize the mammaries of characters that do have them, or put them in places where they don't belong. Prominent breasts, or lack thereof, is one of the simplest instinctive visual cues for hominids. Giving all female animals big boobs, or at least a body shape that mimics them, allows for distinction between the sexes without adding glaringly obvious costume tags, a wasp waist, or the more bizarre gender-specific characteristics in some other animals. In such works, male animals are not neccesarily given obvious pectorals. This can be said for most male cartoon characters, and not just male animals.

If the character is an alien or artificial life form, then it makes a little bit more sense. Aliens have Bizarre Alien Biology after all, and creators of synthoids and such would probably want their "children" to be anthropomorphic enough to fit in. Not to mention that it's easier to design a skin-tight rubber bodysuit with strange textures for use by human actors. However, it tends to make a lot less sense when applied to avian and reptilian races of creatures or aliens. Breasts are for nursing young, and for an Avian with a nice hard beak (especially those with curved or hooked beaks) that would be incredibly painful. Reptiles often have sharp teeth and often strong jaws, too, same with some fish. Remember, breasts are primarily for nursing young - not just to look sexy.

This is common in the Furry Fandom, though some furries prefer to just portray a reptile, avian, amphibian, or their mythical cousins (Gryphons and Dragons) without them for anatomical purposes. Even when this trope is averted in canon, it seldom stops the Fan-Artists. There is also the school of thought of multiple breasts on aliens or furries but that's a completely different subject altogether.

Just in case male non-mammals feel left out, note that external genitalia and nipples are also a "mammal thing", and their presence in male creatures from other taxonomic groups is a variant of this trope.

This Trope is sometimes found with Non-Mammalian Hair, hair being something else that only mammals have but is often added to non-mammalian females. Compare Bizarre Sexual Dimorphism, Organic Bra, Multiboobage, Secondary Sexual Characteristics, Tertiary Sexual Characteristics, and Feather Fingers.

Anime & Manga
  • Technically every Digimon with breasts ever, but special mention goes to Arukenimon, a spider woman. They're not immediately noticeable, but they're there. Justified as it's based on a Youkai known as the Jyorogumo (prostitute spider), a spider demon that poses as a beautiful woman, often a hooker, to lure unwary men to its lair to be eaten and/or fed to its young. Presumably its "breasts" are something it evolved as a form of aggressive mimicry.

Comic Books
  • The original origin story for Marvel's first Spider-Woman, Jessica Drew, was that she was a hyper-evolved spider who had been genetically engineered by the High Evolutionary to look completely human (some people, apparently including Stan Lee, felt that this was going too far even for comic book science), and a well-endowed human at that. This origin story was retconned away to be that she had been bitten by an irradiated spider pretty quickly though, so this issue did not come up for long.
    • Actually the second origin was that she developed radiation sickness because her home was on top of a huge uranium deposit and an experimental spider-serum plus years hooked up the High Evolutionary's machines saved her life. Being bitten by a Spider came in in the TV series, and in the Spider-Woman's origins mini-series which was written much later.

Western Animation
  • A spider who teaches Katy to knit in Katy Caterpillar has an impressive set of boobs.
  • Blackarachnia in Beast Wars; necessary for her Black Widow / Femme Fatale motif.
  • Spydra from Gadget Boy & Heather. However, she appears to just be a woman in a spider costume, and being an Expy of Dr. Claw from the original Inspector Gadget cartoon very little is known about her true self.

Anime and Manga

  • Some of the female ducks in Disney comics.
    • Mocked by legendary Disney comic book artist Carl Barks himself. One humorous self-portrait showed him making a sketch of a sexy, nude woman... using a rather annoyed-looking duck as a model.
    • Don Rosa (and DuckTales animators) drew Glittering Goldie with this trope; her creator Carl Barks didn't. Make of that what you will.
    • Don Rosa has also drawn Magica de Spell with them - or at least with cleavage.
    • Daisy herself has appeared on occasion in the old cartoons to have breasts in shorts like Mr. Duck Steps Out and Donald's Double Trouble. Obviously, this wasn't permanent, and except for a few instances like Quack Pack, she's been dodging the trope since then. She does, however, have a body shape that suggests womanly curves.
    • Lyla Lay in the modern version of the Paperinik/Duck Avenger (Donald as a superhero) comic as most of female duck characters. Although she's not an actual anthropomorphic duck, but a droid designed to look like one.
      • The actress Paperilla Starry, a minor character, show to be very busty in PKNA #15.
    • Kay K, the cute spy from Double Duck storyline (Donald as superspy) that is set in the same universe of PK.
      • In the first story-arc, when she's wearing a classy opera dress, even Daisy gets cleavage. However this is more a case of Depending on the Artist.
  • In the Marvel Universe, the Shi'Ar are specifically stated to have evolved from birds (this is the reason why Deathbird, a Shi'Ar who is an apparent evolutionary throwback, has both wings and talons on her fingers). They also reproduce by laying eggs, which are incubated in a communal hatching chamber. Yet they are portrayed as humanoid in all other respects, including female Shi'Ar having breasts.
  • As indicated in The Comics Curmudgeon's quote at the top of this page, the comic strip Shoe gives breasts to every single female in its all-avian cast.
  • The Italian comic Ava features this. To be clear the main characters are a humanoid duck and chicken, and both have not only huge breasts but also a slim waist and other stuff.

Films — Animation
  • In Happy Feet, the penguins are barely stylized at all, but the females have shading in their chest feathers to suggest a bosom. Truth is stranger than fiction; it turns out that Emperor Penguins do keep a milk-like substance stored in a gland by the esophagus, but it's actually the males that do this.
  • The same is true of Lani Aliikai in Surf's Up.
  • Goldie, a pheasant, in Rock-A-Doodle.
  • The Contessa, Hungarian hawk and Olympic fencer in Animalympics, has a shapely figure both above and below, accentuated by a dashing blouse and riding breeches. She also has eyeshadow and eyelashes for good measure. Other bird characters, like Babwa Warblers, are treated more naturally; Contessa happens to be the most human-like.
  • Stella the goose from Balto 3.
  • The female birds in the Disney film Valiant have much more prominent chests than the male birds, particularly the main character's obligatory love interest, a small nursing dove. The females also have a small central indention and shading in the chest that would suggest cleavage.

Films — Live-Action
  • In Howard the Duck, the eponymous avian hero at one point ogles a "Playduck" centerfold, who has breasts (with nipples). And only a few minutes later, we see a female duck in the bath!
  • ASAIR one of animations in Super Size Me suggested that McNuggets was made from old hen breast. And by breast we do not mean the meat which is on rib cage but old-human-like breast. It Makes Sense in Context. They were explaining how originally, McNuggets were made from chickens with larger than normal breasts. So to demonstrate, they drew a chicken with pendulous breasts so big that it had to walk with a cane.

  • The Omwati of the Star Wars Expanded Universe are apparently bird descendants that look like humans with feathers. This includes breasts on the women.
  • China Miéville's Bas-Lag books feature a lot of xenian characters, some of which fall under this trope. His garuda are a bird-like Winged Humanoid race, female members of which possess slight ornamental breasts useless for lactation.

  • The album Atomic Roooster by Atomic Rooster features a flying bird with naked human breasts. In a transparent cube.

Tabletop Games
  • The fan-spoof Girls of Talislanta series erupted into controversy when the avian Aeriad were drawn with breasts. The controversy was eventually solved when the pose was changed so that the female Aeriad faced the other way.

Video Games
  • This is played with in Serious Sam 3 regarding the Scythian Witch-Harpy, which appear to be humanoid women with bird wings and feet. The creature's data file indicates that its breasts are actually non-functional, and are merely a false facade (a form of evolved predatory mimicry) used to attract primate prey for the harpy to kill and eat.
  • Wave the Swallow, per usual for post pubescent Sonic the Hedgehog cast, of Sonic Riders, though there is as much official art being flat-chested as official art showing budding of the chest. The in-game model tends to the former.
  • Starbound has the Avian, a group of alien birds who resemble jays. The females are noticeably busty.
  • The Legend of Zelda:
  • Turians in Mass Effect are based on birds of prey, and scrapped dialog in Mass Effect 2 does indicate that they think that human (or asari) breasts are an odd feature. However, when female turians are finally revealed in Mass Effect 3, they seem to have breasts.

  • Nazi spy pigeon Hatta Mari in the Looney Tunes short "Plane Daffy". Also a red headed duck who called herself 'The Body' that was strongly attracted to Daffy Duck in the cartoon "The Super Snooper".
  • The Mighty Ducks series has three prominent examples of this, with Mallory, Tanya, and Lucretia. All of them, are female, anthropomorphic, alien ducks.
  • In South Park's Thanksgiving Episode "Helen Keller! The Musical," the kids get a trained turkey named Alinicia for their school play, with a pronounced chest clearly meant to suggest breasts.
  • Daisy Duck of all characters, was given cleavage for the Quack Pack series. Her character was also completely redesigned into a sassy, female reporter-type as well.
  • Regular Show has Margaret the robin. In her first appearance, she's showing sideboob, and in her second (which was part of a brief dream), she has on a Seashell Bra.
  • Several original female duck characters on the cartoon DuckTales. One of the stand outs being Featherika Von Strangeduck in the episode "Hotel Strangeduck". Male ducks like Launchpad have their bills shaped like chins — and having arms and hands rather than wings, and speaking English, etc. — so breasts seem in line with these other adaptations. Darkwing Duck, being in the same continuity, also featured this; just look at Darkwing's Love Interest Morgana MacCawber, who looks like a cross between the Bride of Frankenstein and Elvira, Mistress of the Dark.
  • The Penguins of Madagascar episode "Miss Understanding" has Skipper thinking he's a female due to a misreading of a DNA test result. During a few scenes showing how his new gender identity causes confusion during missions, the boys go for the chest bump after a successful completion but Skipper and Rico are both uncomfortable with that due to Skipper's newfound (and nonexistent) female features. Notwithstanding that they're BIRDS and don't have mammaries to begin with (or that Skipper really ISN'T a female anyway).
  • Every adult female bird in Birdz, but Miss Finch ups the ante with Hartman Hips. And Morty is a rare example of "male non-mammal with nipples".
  • Gorgeous Gal from the Woody Woodpecker cartoon "A Fine Feathered Frenzy". She was an overweight and elderly crow with large breasts. Although because she was overweight each breast was almost the size of the Woodpecker himself. Played as a double entendre when she appears on a large black and white TV screen from her chest up wearing a low cut evening gown. When she was right behind the Woodpecker Gorgeous Gal asked him with her sexy voice, "How 'bout a twosome hon?"
  • The other prominent female character in Beast Wars, Airrazor, while not as obvious as Blackarachnia, still had a rather conspicuous chestplate. The Transmetal version of her that never made it into the cartoon plays it straight.
  • The pigeon, the rooster, and Duck from Almost Naked Animals have nipples. Also, the female ducks in the episode "Duckling Duck" have boobs.
  • The Cuban animated short La Pavita Pechugona features a female turkey with an over-sized bust.
  • The Silly Symphonies short, "Who Killed Cock Robin" features a female wren named Jenny Wren who is a clear Captain Ersatz of Mae West. Her chest is very puffed out and even forms cleavage when she inhales.
  • Lady Bade-Baden in The Raccoons is a bird and has a huge buxom.
  • The 1993 Biker Mice from Mars episode "Unforgiven Cheese" featured a bird-woman bounty hunter with prominent breasts named Billie Monnie.

Real Life
  • Believe it or not, there are some birds who appear to be a case of this trope. They are a subversion, however, in that none of them have actual mammary glands and instead what appear to be such actually serve a different purpose. For example:
    • The male sage grouse has a set of inflatable throat sacs that are huge and pendulous, making them look like a huge pair of breasts. For added hilarity, the males will participate in what can best be described as Gainaxing contests in order to attract females. The actual purpose of the sacs is to amplify the birds' calls, as well as indicate that he's physically fit enough to sire strong offspring.
    • The now extinct Rodrigues solitaire (a close cousin of the dodo) was said to have had a crop (a special and sometimes bulbous compartment in a bird's throat used to store food) that "resembled a woman's bosom". Granted some think that these reports should be taken with a grain of salt.

  • The Mantis race in Invincible.
  • The Forager in Countdown to Final Crisis. In fact several panels are devoted to showing how much she has breasts, after taking a shower at Jimmy Olsen's place.
  • The collector's club comics-exclusive Beast Wars character Antagony is a black, female version of Inferno (who technically ought to be female anyway, considering he turns into a soldier ant, but that's neither here nor there). The compound eyes on her chest, made from the head of her ant mode, are usually drawn as boobs.
  • The Mantis-headed X-Men character only known as "Offset" is a four-armed alien commando that well, as the trope says has a pair of very prominent mammaries; very, very prominent. She somehow gets by the radar having them practically uncovered with her Stripperiffic outfit. Also she (and the artists) seems to like throwing them in everyone's faces at every possible moment, almost as if to tempt you to be attracted to the mantis alien, and as we all know, that's just asking for trouble(knowing what happens to male the mantis after mating) But with that body and a pair like that, it might just be worth the risk. But then comes to mind that she also has a paralyzing poisin, super strength and has tried to eat human characters in the past. Proceed at your own risk.

  • Honey B. from Banjo-Kazooie sports a pretty impressive pair, and a distinctly waspish waist. In fact, this applies any time a bee- or wasp-like character in a funny animals situation isn't a gigantic engine of stinging death instead.
  • In both Bug and Bug Too there are examples. In the first title there's Bug's girlfriend, while the sequel sports some multiarmed amazons with large breasts in some levels.
  • Q-Bee of Darkstalkers fame similarly has a female body with... generous proportions. But it's revealed that this is all a ploy to capture unsuspecting men for her and her hive to mate with and eat (in her victory poses, she even pulls out a knife and fork). This is most evident by the fact that, in her battle stances, she is posed with the buglike eyes on top of her head leading the body, since the ones on her face are entirely decorative (and form part of her mouth).
  • Princess What's-Her-Name from Earthworm Jim has the total package: boobs, really Impossible Hourglass Figure, and Hartman Hips. However, it's hilariously subverted in that by her own species' standards, she's considered a hideous mutant, while her sister, Evil Queen Pulsating, Bloated, Festering, Sweaty, Pus-Filled, Malformed Slug-For-A-Butt (which describes her looks pretty well) is viewed by her subjects as the World's Most Beautiful Woman.

    Reptiles and Amphibians 
Anime & Manga
  • This is common in One Piece, in which zoans (people who can turn into animals) usually retain several human features in their half animal form, including hair and, in females, breasts. Even in the case of two female characters who can turn into snakes. At least they didn't have nipples.
  • In My Hero Academia, Mineta briefly wonders why the resident Frog Girl has breasts.

Card Games

  • Alexandra in the French comic Dungeon: The Early Years.
  • The Skrulls of the Marvel Universe are usually referred to as reptiles; they're green, anyway. Would be justified, as they are shapeshifters, if the few female skrulls shown in their "natural" form weren't as vulnerable to the Most Common Superpower as everyone else in MU. They have hair, so maybe they're egg-laying mammals, not reptiles; apparently they lay eggs and then nurse their young after they hatch.
  • Nessie from Richard C. Moore's Boneyard, despite being a female version of Gillman from the Creature of the Black Lagoon, outsizes all the other girls by several cupsizes. This was lampshaded in an issue that took place at the beach when one of the characters asks "Why does a lizard have such huge tits anyway?"
  • Tricerachops of Super Dinosaur is a half-dinosaur, half-human mutant who evidently has mammaries.
  • In the Sigil series from CrossGen, female saurians have pronounced busts.
  • In Karno's Here They Be Dragons the captive horse-man pisses off the female dragon for mistaking her for a man just because she's flat-chested, to which she points out mammal's obsession with breasts. She grows a pseudo-pair when aroused, comparable to goosebumps or mating signals, that expands the more the two have sex with each other.
  • In the German Club Nintendo comic, one storyline has an apparently older Wendy O. Koopa drawn with hair and breasts.
  • "Snake Tales" by Sols (Allan Salisbury). His snakettes do not only have impressive boobies, but also secondary (long eyelashes) and tertiary (bows) characteristics. Just to be safe.

Fan Works
  • In the Shadowchasers Series, the ophidia are a race of Snake People where this is common for females, and Non-Mammalian Hair is occasionally found on both genders. This is actually brought up one chapter of the second fic, where it states a female ophidia's mammaries are non-functional, and if they ever nursed their young, it was millennia ago.
  • The Jackie Chan Adventures fanfic Jade Dragon hilariously subverts this. At first, it appears that Fei Cui Huo — Jade's Alternate Universe demon counterpart — is heavily endowed, despite being a dragon. Then she reveals that it's padding, since as a reptile, she lays eggs and therefore doesn't need mammaries.

Films — Live-Action

  • The Falleen from Star Wars, although, technically, they're reptomammals. Granted, there were indeed mammal-like reptiles in prehistoric times. But designating the Falleen as such was probably an attempt to justify this trope. And anyway, if they fed their young on milk, it's very likely real synapsids did it like modern monotremes, who secrete milk from a diffuse region of skin and thus don't have... "large tracts of land". The real reason is because Falleen are supposed to be appealing to a wide variety of species, and being human-created this means breasts must be on the females.
  • In Larklight, a reptile girl (who is presumably the equivalent of a teenager) is remarked upon as not having these — specifically in the context of how ridiculous it makes her look when she wears a dress not specifically tailored for her. The tail doesn't help matters there.
  • Jack Chalker's Well World series included a naga-like species with six arms and six breasts, though these were later retconned into glands for storing water.

Tabletop Games
  • Dungeons & Dragons:
    • The Yuan-Ti in are snake people. It may have something to do with being able to inter-breed with humans (indeed, some supplements explain that "the yuan-ti are descended from evil human cultists who mixed their bloodlines with those of serpents", which is itself impossible); but it was probably due to... "artistic license". In some editions, this is explicitly the result of magical assistance from a demon lord worshiped by the cultists, making it a case of A God Did It.
    • 4E has this with the Drakkoths, which are an unusual mixture of crested lizard upper torso and the body of some sort of spiny-tailed drake in the style of a centaur. The females, despite the obvious reptilian nature of these creatures, have breasts.
    • Many fans of the game that followed the online discussions around the time of the release of the 4th Edition might remember the Internet Backdraft concerning the new Dragonborn race that was Dragonboobs!!! In 3.5 they had an excuse: Dragonborn were created by magical religious ritual from humanoid volunteers, who kept attributes from what they used to be after being transformed (so a dwarf would become a short and stocky Dragonborn, and a female would usually have two visible bumps on the upper part of the torso). This was changed to Dragonborn being a proper race of their own in 4E, but they still kept the 'humanoids modified to look draconic' appearance, including the mammary-endowed females.
    • Medusas are likewise endowed, but depending on which edition's artwork you go by this is either perfectly logical (only snaky hair) or slightly squicky (scaly and monstrous all over). In either case the in-universe reason has nothing to do with feeding offspring, instead using the resultant feminine silhouette to lure human men as mates, prey, or artwork.
    • The artwork accompanying one of the Voyages of the Princess Ark CD&D articles in Dragon included a female lizardfolk shaman with substantial breasts.
  • The (presumably male) artists of the German Fantasy tabletop roleplaying game Arcane Codex like to put breasts on everything. Even on the females of reptile people. Considering that Arcane Codex has at least a dozen playable races and more classes to choose from, with full-color artwork in scantily-clad detail, that's quite a lot of breasts. They'd probably put breasts on seahorses, if they could get away with it.
  • In Exalted the signature Casteless Lunar NPC, Madame Vert, is seen most frequently in her hybrid beast(wo)man form, a humanoid Claw Strider with the proportions of a swimsuit model such as here; WARNING: nipple outline may make this NSFW. While there's some sense there — her most natural shape being a human woman — it's still breasts on a scantily-clad lizard-woman.

Video Games
  • Everquest II made Iksar females significantly slimmer than males, and gave them breasts, albeit breasts that could only be described as "minimalist" by MMORPG standards.
  • Several Kremlings from the Donkey Kong Country series (particularly Klump and K. Rool) have nipples. Klump also provides an example of non-mammalian manboobs. Kalypso is a straight female example.
  • In The Elder Scrolls series, the female Lizard Folk Argonians have them (with no real explanation given) in every game except for Morrowind. (Where other characteristics were used to differentiate Argonian sexes, including differences in head and body shape as well as different colorations and types of Alien Hair.) Even in Morrowind, gendered armor types on female Argonians would still include feminine shaped chest armor. Possibly a case of Gameplay and Story Segregation, as the games since Morrowind all have the beast races' bodies use the same shape as humanoid bodies, just with different textures, possibly to save time and work for the 3D artists.
  • The Tarka in Sword of the Stars appear to be reptilian. Their females lay eggs but have clearly-defined breasts. However, the manual states that their internal structure is much more similar to primates than reptiles.
  • In the Pardus browser MMO the Keldon species has breasts. Why? as the original maker of the images said, "Keldon women do have boobs. Reason: because I like them and I did the original race design, and Baldur [Game Developer] has agreed upon it."
  • The Final Boss of Drakensang, Malgorra goes in One-Winged Angel and turns into a giant, three headed serpent. However, she still retains her nipless breasts at the base of her central head.
  • As part of her Skylanders redesign, the plates on Cynder's underside were modified so that her upper chest has two plates side by side and are noticeably round, while the rest of the plates are flat. Her design got tweaked a bit for Skylanders: Giants, and her new toy is completely flat.
  • Why do the female Saurians in Star Trek Online have breasts? It's not even as if, being a Federation race, you can put them in an armoured corset and have them show off the goods.
  • Guild Wars 2 has the Krait whose females have mammaries just like a mammal would, how functional said mammaries are is up for debate. But given that the Krait appear to work in groups and communities, it is possible that they do breastfeed their young.
  • The Mortal Kombat series has a race called the Saurians (Also known as Zaterrans, after their adopted homeworld), of which the most prominent female member, Khameleon, sports a pair of breasts.
  • XCOM 2 features the true form of the Thin Men from the previous game - and the female Vipers sport breasts. Given that the game is set in an Alternate Timeline where X-Com lost the fight, this led to the Internet to guess why Earth decided to surrender. In-game, the autopsy for Vipers explains that they're basically specialized venom glands; the ability to use pectoral muscles to contract the oversized glands is what lets Vipers spit poison so far and in such quantities.
  • In Chrono Trigger, among the enemies in the prehistoric era you will find obese terrasaurs who sport protruding belly-buttons with breasts above them.

Web Comics
  • In reference to the D&D Flame War listed above, the gang at Full Frontal Nerdity get stuck pondering whether or not female Dragonborn would have breasts.
  • Veled of Last Res0rt has possibly the largest rack of the cast. Hers are at least justified by the fact she's not all reptile.
  • Wereworld is set on a planet where "Lycanthropes" can shift between animal, human, and hybrid form. All female Lycanthropes have breasts. There are also dragons (who are not Lycanthropes) and the females of the species have no breasts, no hair, no nipples, nor anything that would indicate their gender to a human when compared to the males of the species (they have mohawk-like ridges and horns that look like hair, but no actual hair). This is spotlighted when Blaze, a female dragon, is chosen to make contact with the main character as a messenger of the dragon council. It is quite a humorous scene when Aris, another female dragon, tries to explain to Blaze that she looks like a male to other species, regardless of how sexy she looks to dragon males. This is fixed with the dragon unique ability to shapeshift, which she uses to assume a more human form. However, Blaze misunderstands Aris's explanation of "the importance of having breasts among the other races", and gives herself far too large breasts. This led to Blaze's humorous line "If you're gonna do something, do it grand". So far, no other non-mammal lycanthropes have shown up to compare the dragons to.
  • The female Nagasta (sort of merfolky-lizardy people) in Dominic Deegan have prominent breasts. When one reader asked Mookie why, his answer was "I like boobs."
  • Played with in The Order of the Stick, strip #676, where only one of the two reptilian hookers has breasts — they're implants, which her co-workers find ridiculous. (Given the accompanying dialogue, this is likely a reference to the dragonborn, as mentioned above.) Lampshaded in the prequel book Start of Darkness:
    Oracle: Now get out, I have a hot date with this kobold chick, and my oracular powers tell me I'm getting to second base tonight.
    Eugene: Wait, if she's a reptile, how do you get to second base?
    Oracle: OUT!
  • Harkovast, a fantasy webcomic featuring various animal races, features a reptilian race called "Tsung Dao" whose females fit in this trope. However it is explained that in this magical setting, all races can cross breed, making the need for mammary glands a somewhat universal adaption.
  • All of the female dragons from Draconia Chronicles seem to fit this trope.
  • In this panel from Concession, Angie feels she's justified in not wearing anything above the waist because of her reptilian biology.
    "What's there to reveal? I don't have breasts! I don't even have nipples!"
  • The frog creature from Ow, my sanity.
  • Aylee the alien from Sluggy Freelance has booby-looking things sometimes. "Bring back phase two!"
  • Broken Plot Device has both Lizardbeth and Inix, the former an Iguana, the latter a Dragon. Not particularly busty compared to the mammalian cast, however.
  • A NSFW Oglaf strip lampshades this — the unnamed man is too busy looking at a Medusa's bare breasts to look at her face and be petrified. "Heh, snake tits."
  • The Stormrunners features Ssuara, a soldier of a Martian race 3.5 billion years in our past. Although basically reptilian she has large and very human-looking breasts (and incidentally she's always naked). It seems this is a deliberate piece of cosmetic genetic modification - the Martians had time viewers which they used to view 21st century human culture and presumably pornography.
  • Nip and Tuck both averts and heavily discusses this with Hortense, who becomes a surprisingly sympathetic character when she explains that she is physically incapable of meeting the expectations of femininity created by a mammalian-heavy culture.

  • Shinryaku! Ika Musume: Ika Musume is supposed to be a squid, yet she at least seems from this side of the dress to have the chest — and general appearance, tentacles notwithstanding — of a female human in her early teens. She's also an invertebrate, as stated on the DVD cover, but you'd think from looking at her that she has an internal skeleton, so...

    • The Legend of Zelda: Breath of the Wild continues with the tradition of flat chests for male Zoras. Female Zoras do have breasts, but they are small to the point where you'd have to be looking at them closely to notice. The Zora princess, Mipha, also falls under the same boat. The only difference between male and female Zoras are in skin color where males are green, blue, or black while females are magenta. However, the Zora prince, Sidon, is magenta colored.
  • The Naiads from God of War. Poseidon apparently gussied his daughters up, presumably to make Spartans want to make out with them.
  • In Call of Cthulhu: Dark Corners of the Earth, Hydra, giant queen of the fish-like Deep Ones, is depicted with breasts. It is known that Deep Ones can interbreed with humans, and therefore must presumably share some genetic material, and it's worth noting that the usual reason of making the female creature more attractive/feminine definitely doesn't apply here — imagine the Stone Age fat goddess idols, and add a few extra pairs of breasts, scales and sharp, fishy teeth.

    • While no clear judgement can be called on the squid-based Inklings properly shown in-game, a few of the Sunken Scrolls depict images of adult female Inklings with developed mammaries in their humanoid form, with their hair-tentacles pulling a Godiva Hair to keep everything E-rated of course.
    • Octarians seem to have more pronounced breasts than their inkling counterparts. Marina from Splatoon 2 certainly has breasts.
  • Nami in League of Legends is a member of the Marai, a mer-humanoid race. She not only has breasts, her coat of scales opens above her waist, Absolute Cleavage style, to show them off better. This was eventually justified by explaining that her people are the result of humans interbreeding with nature spirits centuries ago, creating several families of humans with animal characteristics.

Web Original
  • Parodied by the Mermaids in Tales of MU. They have breasts but are ignorant of lactation. Instead, they are used to get free beer and lure sailors to their doom.

Western Animation
  • On Captain N: The Game Master in the episode "I Wish I Was A Wombatman" there was a short well endowed blonde haired pink octopus who wore a pink dress. She fell in love with Simon Belmont at first sight even though he wasn't interested. The cartoon ended with her chasing him so she could make love to her 'dream boat' all while leaning forward and exposing the top of her ample cleavage.
  • Short-lived series Fish Police features anthropomorphic fish. Didn't help one of the main characters was a blatant pandering to dads who might be watching. This also applied to the comic that the show was loosely based on.
  • Female Decapodians from Futurama are humanoid shellfish. As Decapodians die immediately after mating, leaving their fertilized eggs behind in the sea, females of their race would never get the chance to use breasts as Nature (as opposed to Fanservice) intended. According to Word of God, their "breasts" are actually egg sacs. Still, the ones with the biggest are considered the most desirable. Then again, bigger egg sacs likely means more eggs.
  • In SpongeBob SquarePants some female fish wear bras.
  • The original 1993 Biker Mice from Mars and its contested 2006 Sequel Series both featured a race of fish aliens called the Plutarkians. Female Plutarkians were shown to have breasts, most notably main antagonist Lawrence Limburger's sister Latoyah, one-shot villain Romana Parmesana, and the unnamed female member of the Plutarkian Council.

    Non-Human Mammals 
  • A bad case of research failure resulting in unintentional squick is the advert for Nestlé Cereal Bars on UK TV, using an animated character called "Uter the Cow". Uter spoke with an Arnold Schwarzenegger-style voice, and had some sort of gun-like contraption, attached to his(?) udder-area by means of a long tube, out of which he expelled what was presumably meant to be milk.

Anime and Manga
  • The Minks of One Piece are an entire race of anthropomorphic animals. Naturally, the females have this quality, regardless of what type of animal they are.

Films — Animation

  • Played with in the Discworld novel Feet of Clay, where with Cheery noting about how hard it is to be openly female and a dwarf, Angua (a werewolf) muses internally that at least she doesn't feel like she should be wearing three bras sometimes.
  • In one of the Myth Adventures novels, a woman is attempting to use an illusion to look like a werewolf despite never having seen one. Later on, when she meets one, the female werewolf laughs over the, "And you only had two breasts."
  • Somewhat related: the Redwall series has a unique problem. Most of the characters are mammals, but there are no non-anthropomorphic mammals (besides the horse in the original novel and it's been more or less retconned out at this point). Yet they are always eating cheese. It was eventually explained that the milk is "Greensap milk", produced from "roots and tubers". (Mm, tastes like Deus Ex Machina. But at least it avoids the potentially embarrassing problems of locating the real stuff...)
    • On one episode of the Nelvana cartoon, Matthias suffers an instance of Marshmallow Hell at the paws of Constance Badger. (Constance is the only character to have noticeable cleavage.)
  • Weird example: In the nature Mockumentary book Snouters, one species of this fictious mammal taxon always sports prominent breasts resembling those of humans... even in males. Justified, at least in theory, because the species in question lives symbiotically with another, and trades milk for this other species' assistance in finding food. (Doesn't explain why the breasts look so much like a snippet of Playboy got photoshopped onto a fuzzy little critter, though.)
  • In Taylor Anderson's Destroyermen series, there exists a species of cat-lemur humanoids called Lemurians, fittingly enough. Lemurian females have been noted early on that proportionality with humans are very similar, specifically the breasts. This leads to some comedic/awkward moments as the bulk of the humans are sex-starved males, and one of the secondary conflicts of the series.
  • In M.C.A. Hogarth's Paradox series the Pelted races vary considerably on this point, considering they lie all over the Sliding Scale of Anthropomorphism. The alien Chatcaava are said to be mammals (despite looking like dragons) and most of their females have human-like breasts, the Slave Queen being an exception, given her more masculine secondary sex characteristics.
  • Averted in Animorphs—Andalites are centaur-like aliens who could probably be classified as mammals, but the cover art gives Aldrea a decidedly "masculine" figure.

Live-Action TV
  • In a MADtv skit, Babe the pig is a half-human, half-pig who is on Baywatch. All of the Baywatch lifeguards are upset until he gets a bikini top which covers his multiple rows of nipples.
  • The Muppet Show depicts Miss Piggy as having breasts.

Tabletop Games
  • This issue comes up a lot where anthropomorphic cattle are concerned. (And see also Furry Confusion.) To wit:
    • There was a rather amusing discussion on whether female minotaur PCs of the text-based RPG Grendel's Revenge had "Udder Armor" or "Breast Plates" as part of their armor set. Thankfully, One Size Fits All provided no specific answers.
    • Similarly, female Tauren in World of Warcraft have normal human breasts instead of udders, making for some really weird appearances. Though proportionately, tauren females are quite petite compared to the other races.
      • Fridge Logic: The gargantuan udder on dairy cows is a product of artifical selection, which would never have happened for the sapient Tauren.
    • Minotaurs in the Dungeons & Dragons setting Dragonlance. In one piece, a human taken captive by seafaring minotaurs notes that the first mate, whom he'd initially mistaken for male, has (modest) human-like breasts beneath her leather armor.
  • In Dungeons & Dragons 3.0e, the artwork on the Monstrous Manual depicts Gynosphinxes with prominent breasts. This is on par with mythology, though.
    • The original Monster Manual portrayed Gynosphinxes this way too.
  • Rifts plays it both ways. Female Dog Boys are engineered to have humanlike busts apparently solely because it makes them more familiar and acceptable to humans... but considering the variation between canine-like and human-like physiology within the species it's possible some don't. Kill Hounds, which are more in the plausible deniability column, have no such niceties. The feline Battle Cats have humanlike breasts as well. Their Kill Cat cousins, the rat and bat conversions, and the Ursa Warriors are anyone's guess; very little art of them exists.
    • A female Mutant Rat in the Machinations of Doom comic has 'em.

Video Games
  • Wing Commander seems to be a little confused about this. In the "Secret Missions" add-on to the original Wing Commander, the Kilrathi priestess is shown with a multi-part bra covering three sets of human-style breasts, while the Wing Commander Academy cartoon showed the relatively few females that were seen as being flat-chested, and the intro to Wing Commander Prophecy has a wall drawing of a Kilrathi female with one pair of human-style breasts.
  • The female Khajiit Cat Folk in The Elder Scrolls, who have normal human breasts. In Oblivion, this almost seems like laziness on the part of the developers, as all humanoid characters have the exact same male or female body model, merely retextured and with a few features added (Claws on Argonians, tails on Khajiit).
  • The fox spirits in Jade Empire have rather... pronounced... secondary sexual characteristics. They're a rather obvious expy of Huli Jing, a mythological race known for using sexuality to confuse and utterly screw with humans.
  • Star Fox. Every prominent female character in the series when shown in full-body profile possesses breasts. Krystal is probably the most notable given the outfit she appeared in during her debut.
  • Much of the female cast from Sonic the Hedgehog.note  Rouge has these by default. (Pregnant or nursing bats develop breasts, though obviously, not ones like Rouge's.)
  • Mrs. Boggy in Banjo-Kazooie. One of the most blatant of the game's many very inappropriate (and thus hilarious when discovered) hidden references/images, most of which are 100% more subtle than... those. They're at least completely covered, but just look at her running animation and make your own decision as to whether you're supposed to notice or not.
  • In Guild Wars 2 the Charr females have no breasts, but one of the Anet Art Designers came out and said that the Charr Female were either going to lack breasts entirely, or they were going to have six.

Web Comics
  • In Nip and Tuck, most every female depicted of whatever species (apart from Hortense, a lizard) is amply endowed.
  • Sluggy Freelance hung a lampshade on this with the "Star Trek Adventure" where they meet an amazingly pneumatic Alien who is a male of his species.
  • The Whiteboard: Pretty much all of the regularly depicted female funny animals (all based on mammal species) are rather well endowed with human style breasts, which isn't treated in the comic as being unusual in any way.
  • Broken Plot Device, aside from the reptilians with breasts, has cats, rabbits, elephants, rats, and other animals with boobs; with the largest pair owned by Sunny, a mole.
  • TwoKinds: Keidran women have human-like breasts, but also several pairs of mammaries down their stomach (all hidden by fur).
  • Freefall has Florence Ambrose, a "Bowman's Wolf" with a human-like body. She has multiple pairs of mammaries (conveyed amusingly by multiple censor bars when someone looks at her), but her body outline resembles a human female's in its silhouette. Note that a wolf or dog would not have protruding breasts save when lactating.
  • In Poppy O'Possum most female mammal characters have humanoid breasts, with the exception of marsupials like opossums. Though Poppy shoves a pair of balled up socks down her front to make it look like she has boobs.
  • Sequential Art: All of the female furries featured so far are prominently well-endowed. This seems to be a running theme with all of jollyjack's female furry characters, often to ridiculous extremes.

Western Animation
  • The Amazing World of Gumball is a place where Everything Talks, and almost avoids this trope, with many of the females lacking all the Tertiary Sexual Characteristics. The exceptions seems to be Ms. Simian (a baboon) and Granny JoJo (rabbit), who have very noticeable, sagging breasts, while Richard (rabbit) and Mr. Brown ("furry slug") have rather sizable moobs (the latter is only visible when his fur is out of the way).
  • Animaniacs has Minerva Mink. She was so busty that some shots of her abundant breasts were edited in the DVD collection. The intent was for her full cleavage to resemble a large puff of fur, but resulted in what fans tend to refer to as a "uni-boob". Apparently, what was OK on broadcast TV at 4 pm in 1992 was a little too spicy for a DVD release in 2009.
  • The manatee dummy in one episode of Bob's Burgers.
  • Gadget Hackwrench from Chip 'n Dale Rescue Rangers has a clearly feminine shape even in her usual overalls, and it's especially obvious when she dresses up in her Jessica Rabbit-inspired red dress.
  • In the 1941 remake of the 1934 Disney cartoon Orphan's Benefit, the normally flat-chested Clarabelle Cow gains a human-like bust after being accidentally undressed by Goofy.
  • My Little Pony Tales has an episode where Bon Bon fantasizes about being a supermodel. She imagines herself in a bikini and a one-piece swimsuit both with breasts.
  • Nu, Pogodi! uses this, though, amusingly, the female pigs are depicted as having multiple (eight or so) breasts.
  • Sonic SatAM: Bunnie Rabbot and Princess Sally.
  • SpongeBob SquarePants: When not wearing her space suit, SpongeBob's friend Sandy Cheeks has noticeable breasts, or is at least wearing a bra that suggests that.
  • The Caitians from Star Trek: The Animated Series, Cat Folk which reappeared in Star Trek Online. One forum commenter remarked that, as cats, they should technically have three pairs of breasts.
  • While cows are mammals, the female bovines on Wild West C.O.W.-Boys of Moo Mesa have human-like breasts instead of udders.
  • Sophia the aardvark and Melisa the raccoon in The Raccoons both have two human-like breasts in their chests.

    Various Animals 

  • The Worldkillers from the New 52 plays this straight and averts it. Of the three members confirmed to be female, Reign and Perrilus have this, while Deimax has the biggest most masculine build of the lot, and except for the Non-Mammalian Hair, doesn't look female at all.

Films — Animation
  • Fritz the Cat heavily abused this, featuring bared breasts in nearly every scene in a world populated only by animals, including crows and a frog woman.

Video Games
  • In Mario & Luigi, Bowser gets them after Cackletta takes over his unconscious body — on the outside of his shell.
  • All the various anthropomorphic races featured in the MUCK game SouthernCross. Almost all of the races are human, with a bad tempered Planet-God having tried to kill humanity by mutating them over and over until they died. It didn't quite work, and while a few pure human lines survive, "human" now refers to any anthropomorphic character not explicitly stated as Non-Human. Therefore they not only possess mammalian features that would not be at home on their apparent species, but are also reproductively compatible with other "humans" (but generally not with explicitly stated non-humans).
  • In Star Trek Online, all females use the same body model. This includes Andorians (who have some insectoid features, like a partial exoskeleton and antenna, and four genders, with the one that actually bears the young doing so in a fashion rather like marsupials) and Saurians (lizard-people, what else).

Web Comics
  • Explained away in Triquetra Cats with the Antreyui, descendants of humans who have been spliced with the DNA of animals, so they're not so much anthropomorphic animals but theriomorphic people. The lizard people and bird people may have reptilian and avian traits and features but they are still mammals.
  • NSFW Comix was doing a few comics with dinosaur-related puns, which he called "Dinosaurgy". In one, it shows an ostensibly female triceratops stripping with bare breasts. In the flavor text, he acknowledges that it's impossible since dinosaurs aren't mammals, and therefore, have no mammaries.
  • Jack uses this trope, as it includes insects, birds, reptiles and dinosaurs, all with breasts. Possibly justified, however, as all furries were created from human DNA. It's possible that the mammal/bird/etc classifications are just cosmetic. They even show a mammalian furry married to an insect "furry", with little big-eyed mammal kids with antennae. Oddly enough, they've showed such cross-breeds earlier many times in the series, without the explanation given until well into the story.

Western Animation

    Plants, Robots, and Animate Inanimate Objects 
Anime & Manga
  • Rosemon from Digimon Savers has jubblies that bounce.
  • Mahoro from Mahoromatic subverts this nicely; She's a combat android and so big boobs would only be a hindrance. However on the battlefield of love she finds herself drastically under-armed when it comes fighting for the affections of her Master, so much so that she changes her wish for Earth peace to a wish for bigger breasts as well as asking for a modification from her creators at VESPER in a letter "home." It is promptly denied to a round of applause.
  • Cosmo from Sonic X. In a climactic moment near the very end of the series, she suddenly transforms from a child to a full-grown adult, complete with breasts and child-bearing hips... in spite of the fact that no other female of her species is portrayed with these. Furthermore, the scene comes complete with gratuitous close-ups of her swelling bust and posterior, which makes the whole thing more than a little bit worrying.
  • On an account of Fembot used in Go Nagai's works and Shinkon Gattai Godannar!!, female (piloted) robots have breasts, which are used as giant missiles and gatling guns respectively.

  • T'ra Saa, despite being a sentient plant, embodies this (possibly to avoid alienating readers when she's shown to be in a relationship with a human male). She's made appearances in Republic and Legacy.
  • Most 'female' robots in superhero comics get this treatment if only to identify that they are indeed female despite not having any need for breasts and only being considered a specific gender due to the person their A.I. is based on. That and Fanservice to anyone who's into that sort of thing.
  • Platinum a.k.a. Tina a.k.a. Platina is a robot built by Dr. Magnus creator of The Metal Men. She has the body of a centerfold complete with metal mammaries. Despite this, Dr. Magnus constantly berates her for "acting like a girl" despite obviously having made her in the shape of one. Her creator and programmer also chastises her for her frequent displays of romantic interest in him. Dr. Magnus has issues. When the Metal Men appeared in the Superman/Batman series, Copper looks very much like a "black" (i.e. copper-colored) version of the "white" (silvery) Tina.
  • Adventure Time: Banana Guard Academy introduces female Bananas, who have breasts.

Films — Animation
  • A botched spell from Schmendrick in The Last Unicorn causes a nearby tree to sprout a female face and large breasts, with which it subjected the bumbling wizard to Marshmallow Hell. Possibly justified, as perennially-dateless Schmendrick's subconscious might've affected the magic's effects, and the tree did have a couple of suggestively-placed large boles on its trunk.
  • The hotdog buns from Sausage Party are all female and they have a very noticeable bosom, even when they're supposed to be animate bread.

Films — Live Action

  • The Cactacae of Perdido Street Station. Justified by their being human/plant Mix-and-Match Critters, and implied to nurse their young once they've sprouted.
  • The Neti from the Star Wars Expanded Universe, though they at least are shape-shifters and implied to choose such things because they want to look more humanoid, so as to fit in better in a galaxy dominated by humanoids in general in and humans in particular. However, the Zelosians have no such excuse.
  • Played with in Feminine Intuition. The first couple models of the JN line play this straight, including metal breasts. The final JN-5 model, though, is just a little more delicate in build then a 'male', with a tapering waist and a voice described as liquid and musical.
  • Lampshaded in Cassandra Kresnov: Crossover. By Sandy's own admission, she pretty much only has breasts because her (male) creators didn't like the idea of a flat-chested Artificial Human Super Soldier.

Live-Action TV
  • Jabe, from the Doctor Who episode "The End of the World". Possible justification, as her race ("From the Forest of Cheem, we have... trees!"), may be half-human (one of the "mongrels" referred to by Lady Cassandra). The only stated fact of their evolution is that they are descendants of tropical rainforests transplanted from Earth five billion years earlier.
  • Zhaan from Farscape is a Plant Person. Who gets orgasms from solar flares, incidentally. She does avert Non-Mammalian Hair, though.
  • Lyekka from Lexx. (Unfortunately for Stanley Tweedle she's also "smooth round the bend".) Justified because she is a psychic predator that took that form specifically to prey on humans.
  • A borderline case comes from Star Trek: The Next Generation. The Borg certainly don't breastfeed, but allowed unit Seven of Nine to keep her fairly impressive set of functionless accessories. You would think the Borg would remove them as biological tissue takes energy to maintain, and thus reduces efficiency. Even less explicable are the breasts on the Borg Queen in the movie, but maybe that body was just for formal receptions. The Borg Queen only has her physical body created when she has need for it, after all.


Tabletop Games
  • Dungeons & Dragons has the Wilden, a plant-like fey humanoid.
  • Female Ghoran in Pathfinder have a couple of chest bumps, despite being sapient flowers. This may be justified given that the Ghoran adapted to resemble their human creators, who are definitely mammalian.

  • Whereas the BIONICLE toys are, for the most part, aversions, the movie redesigns played the trope straight, even if subtly. The best example being Toa Metru Nokama, who did have a cleavage, with the top-part of her inner gears sticking out (these gears were less prominent on her male partners). Roodaka's are, in an interesting twist, less pronounced in her movie design. Allegedly her toy, although popular with fans, even caused complaining among certain groups for being so well endowed. However, Word of God says that even the males of her species are supposed to look exactly like her, though the only one we see is tiny and from the back.
  • Several female Transformers, including Arcee, Thunderblast, Beta, and all who are named Blackarachnia. (Most Blackarachnias are also at least partially organic... but they're spiders.) In one episode of Transformers Cybertron you get to see Thunderblast's "breasts"... jiggle. In another episode, she has nipples.
    • In the Transformers Prime series Arcee and Arachnid are both fully metallic (as this continuity drops the organic hybrid angle of past shows), but both still have breasts.
    • Botanica is a twofer: a plant that turns into a robot!
    • Transmetal Airazor was the first ever western Transformers figure to be designed as a female (all others were either aborted during the design phase or were conceived as males but retroactively had their gender changed), and naturally, she has these. She's also partially organic, but she's supposed to be a bird.

Video Games
  • There's a large-breasted sunflower in Conker's Bad Fur Day. You need to pollinate her with the king bee to increase her bust size. Which you can then use as a trampoline. Apparently the dev team originally called them stamens, and then freaked out when, days before release, someone realized that stamens are the pollinator organ, not the pollinatee.
  • Any Robot Girl that wasn't made for Sexbot purposes. Some of the others might be justified simply by aesthetics, but sometimes there is no excuse for the robots to be Ridiculously Human Robots, let alone Robot Girls with huge knockers.
    • Aigis from Persona 3 is slightly justified in that her creators deliberately designed her that way so she could be given a fully-realized, human-like persona (which would allow her to manifest a Persona.) A sexual identity (even if she lacks the necessary equipment) is part of such self-identification within human society and for human interaction.
    • EDI in Mass Effect 3 has the largest chest of any female in the series, which is saying quite a bit. Her body was designed as an infiltration unit that passes itself off as a human, but after the artificial skin was burned off it just looked silly.
    • In the MMO Wildstar, there is a playable race of robots called Mechari, and yes, the females have breasts. Mechari were specifically designed to be a race of Manipulative Bastards, and the more human they look the easier that becomes.
    • One minor subversion is Roll from the Marvel vs. Capcom games. When she uses her Hyper Roll manoeuvre, she grows into a giant robot with good-sized breasts ... that launch as missiles. Repeatedly. She doesn't need to store milk, so why not some RDX?
  • Played with in Guild Wars 2 with the Sylvari, a race of Plant People. They are plants that mimic the human form for backstory reasons, including females with breasts, but they are not actually breasts in the mammalian sense and are non-functional in that role - they're simply plant growths that look like breasts.
  • SCORPIO in Star Wars: The Old Republic has robo-bosoms and hips.
  • A female tree-android, working at Bandai Namco Entertainment, in Tekken Tag Tournament 2's ending for Mokujin (a male tree-android) sports a pair on her oddly shaped log torso. She's been around for a while; Mokujin started with a 'female' torso style in its debut in 3, with breasts and the best you could do to shape a wooden trunk into a dress.
  • In Starbound, female Glitch (robots), Floran (plants) and Novakids (stellar gas creatures) all have quite a pair. The Glitch have the excuse that they're made to think they're organic people who nurse their young. Floran, by contrast, don't even have functional genders on anything other than a cosmetic level, and Novakid reproduction is a complete mystery to all outsiders.
  • In The Elder Scrolls, Spriggans, a hostile tree-like Plant People race, take the form of humanoid females. All have a noticeable bust to their shape as well.

Western Animation
  • In the third Bosko, the Talk-Ink Kid cartoon "Congo Jazz", a palmtree promptly pulls its leaves down like a skirt, does a booty bump, and then proceeds to gyrate its coconuts.
  • Big Brain, the only explicitly Fembot built by Grizzle in Adventures In Care-a-Lot, has a slight curve to her bust and Hartman Hips.
  • In the Christmas Special Christopher the Christmas Tree, a number of anthropomorphic pine trees are talking about why they'll be the first to be picked. One has snow strategically placed to look like a boobs, and she even comments that she's "the fullest" while making her snowboobs jiggle. You can see this starting at 1:25.
  • Many fem-bots on Futurama fall into this category. The thickly-built hookerbot with the low voice is briefly shown in one episode screwing one of her breasts onto her torso, implying that "she" is a transvestite (the "Are you a woman?" "I'm more woman than you can handle, honey" exchange is just the icing on the cake).
  • In the Downtown episode "The Con", Alex and Serena look at Robot Porn.
  • The Schoolhouse Rock character, Interplanet Janet, is half human and half spaceship but sports a pair of metallic breasts.
  • Master-mold from Wolverine and the X-Men is the mother of all Sentinels.
  • Gems in Steven Universe are anthropomorphic, alien gem stones who create humanoid holograms for bodies. Rose Quartz seems to be the only one who had breasts, and she's also the most human looking of them.
  • In a rare male version, Ricardo in The Grossery Gang webseries, a banana, has visible pecs without his peel.

Anime & Manga
  • The Female Titan in Attack on Titan is named as such because it's the only Titan with visible breasts, despite Titans having No Biological Sex and lacking genitalia of any kind. What's more, because the Female Titan has no skin it's clear to see that its breasts are made of muscle, making them doubly useless.

  • The June 1953 edition of EC Comics Weird Science featured a story called "Right on the Button" in which a man marries an alien woman who stabs him to death on their wedding night when she sees he has a navel, revealing that he is a (GASP!) mammal, born from a (GAG!) womb! But like all EC pretty girls, she has great tits!
  • In Guardians of the Galaxy, the Centaurians initially had a marsupial-like pouch instead of breasts (though oddly, the females still cover the chest area with clothing), but when Kevin West took over he promptly gave the Centaurian ladies boobs.
  • In Archie Comics' Sonic the Hedgehog Salma and Juanita, the daughters of Espio, both have hair and, being older, Salma also has boobs. This could be explained by the gene bomb that mutated all life into what it is today in the comics. However, the cover of Sonic Universe #8 shows that Argyle now has distinctly different punk hair which, not only wasn't present in his initial appearance, is rare for any male character, even if they are a mammal (the only other male with distinctly different hair is Antoine the Coyote). Let's see the Xorda explain that one.

Films — Animation
  • Roz from Monsters, Inc. is a slug-like monster, with breasts.
  • It's unclear what the denizens of Planet 51 are but they reproduce by laying eggs, so they're likely not mammals.

Films — Live-Action

  • The Tymbrymi in the Uplift series have shape shifting qualities and as such usually don't have mammaries. If the necessity arises though features with the tactile feedback if not function of breasts can be acquired.
  • M.C.A. Hogarth's Tales of the Jokka: Anadi Jokka have breasts, it's not entirely clear whether they are mammals even though they lactate, give live birth, and have hair, considering that they're aliens and have been known to change sexes during puberty. The descriptions of Jokka reproductive anatomy in The Worth of a Shell don't sound mammalian.
  • In Discworld, trolls are basically vaguely humanoid piles of rock. In the novel Moving Pictures, Ruby the troll lounge singer is described as a cross between a stone age fertility goddess and a foothill. In The Art Of Discworld, Paul Kidby takes the reference to Venus figerines and gives her, in his own words, "a large rocky bust".

Live-Action TV
  • Doctor Who shows a Chimeron woman nursing her child... with a miniature power generator. Chimerons suckle on energy. So why do Chimeron women have breasts?
  • In Star Trek: Enterprise, Trip gets raped by a forehead-of-the-week and grows nipples on his wrists. The alien has normal humanoid breasts.
  • Star Trek: Voyager reviewer SF Debris pointed out the unlikelihood of Kes, an Ocampa, having breasts if her species actually existed in real life, since her species only has to mate once in a lifetime (Ocampa get plenty of foreknowledge of when that mating will take place so there's no reason to "fool" the males into thinking that the females are always fertile, and thus no reason for females' breasts to always remain swollen). Also, expanded universe material suggest that Ocampa give birth in multiples to keep up their populations' numbers, and yet, Ocampa only have one pair of breasts.
  • In Super Sentai female monsters have run the gamut, from insect creatures to robots to animal creatures, the majority of which have had some epic boobage going on.

Print Media
  • A cartoon in a long-ago issue of Playboy showed a landed flying saucer with a bevy of semi-naked, very human-looking, very voluptuous "aliens" surveying the area. Spying on them from behind a nearby tree are two human males, one saying to the other "That's nothing, wait until you see their females."

Tabletop Games

Video Games
  • There's a frankly horrifying case in Darksiders with Tiamat—a dragon/aye-aye/scorpion creature with the head of the thing from Predator... and outlandish breasts.
  • In the MMORPG Earth Eternal the multitude of races, including demons, yetis, cyclopes, and robots, are different in much the same ways humans are. However, all of them, even those that look like birds or reptiles, are actually mammals created by the gods, and closer related to each other (and humans) than the species they resemble.
  • In Grim Fandango, every human character is a stylised skeleton, yet the females have inexplicable bulges on their chests. This is consistent with the Day of The Dead figures that the artwork is based off of, and somewhat justified because the characters are Calaca dolls, not real skeletons. Hence the oversized heads, the non-transparent interior, etc.
  • Mass Effect:
    • In Mass Effect 2, quarians possess mammaries, which are obviously visible in the shape of their survival suits, and at one point a quarian explains that "bubbles" are used when a child is weaned from nursing off their mother's immune system but before they get a suit of their own. In Mass Effect 3, if a male Shepard completes a romance arc with Tali, the picture she gives him shows that quarians very closely resemble humans, confirming that they are mammalian.
    • Cut dialogue from the second game would have suggested turians (bird-reptile analogues) avert this, but no female turians actually appeared until DLC for the third game. Compare Nyreen in her cloak and hood to Nyreen in normal armor.
    • Cleanly averted with the krogans, whose males and females, the latter seen in Mass Effect 3, look exactly alike to a human eye (the females are distinguished by wearing what amounts to a burqa). Inverted when a krogan asks female Shepard if she's female.
      "'Scuse me for askin', but — you're a female, right? You got those funny bumps, like an asari."
    • Speaking of asari, they prefer mating with other species instead of their own for additional genetic diversity. So, what does an asari need to attract a, say, human to meld with? It's even discussed ingame how members of three different species consider an asari attractive. It's also not unlikely that their breasts work as, well, breasts (i.e. for nursing.)
    • In Mass Effect Foundation comics (specifically in Issue 12), drell females are shown to have something resembling breasts, despite that the Codex tells that drell infants are able to eat solid food from the moment they are born. Due to this disparity, some Mass Effect fan artists prefer to go by the Codex implications and portray drell females without breasts. The games themselves do not show female drell models.
  • The Vulcans in Odin Sphere are supposed to be fiery magma elementals but even when transformed they sports jiggly boobs.
  • World of Warcraft:
    • The Draenei are blue alien space goats, about as far removed from terrestrial mammals as you'd wanna get. And yes, the females have boobies. Orcs are alien humanoids as well, and also about as far removed from terrestrial mammals as Draenei, and their females get boobies too.
    • Some earth elementals and Titan creations have breasts as well. If the later can be hand waved as being replica of their creators, they are still made of rock or metal and don't even reproduce sexually.
  • StarCraft: Ghost development renders revealed that female Protoss have breasts, despite the fact that they are aliens unable to eat solid food, being purely photosynthetic. However, StarCraft: Ghost is not considered canon, and the Protoss females so far seen in the RTS wore chestpieces that weren't shaped in a way suggesting bulges underneath.
    • The female Protoss seen in Starcraft II appear to be flat-chested. Zerg Queens, however, have a bulge on their chests that seems suggestive. Though it's possible that Sarah Kerrigan used her own DNA when she designed them.
  • Female Forerunners of the Halo franchise have breasts. It's somewhat justified in that they and humanity were both created by the Precursors and are considered "brother species" by some, sharing many physical characteristic.
  • Double from Skullgirls is a shapeshifter whose usual shape is a grotesque, vaguely liquid mass of viscera, contorted into a crude mockery of the feminine form that includes perpetually-bouncing "breasts".
  • The Elder Scrolls:
    • Atronachs are a type of unaligned lesser Daedra which are essentially the Elemental Embodiments of the elements they represent. Starting with Oblivion, Flame Atronachs take on a more feminine appearance, being made of fire and glowing hot pieces of armor. The chest piece gives them a distinctive bust.
    • Several other varieties of lesser Daedra, including female Aureals, female Dremora, female Mazken, female Skaafin, female Spider Daedra, female Xivilai, and Winged Twilights (who are purely female) also possess breasts. To note, these are loosely demonic entities with Complete Immortality who do not reproduce. They have no biological need for mammaries. It is somewhat more justified for the Mazken than for other "female" Daedra, as they are known to use their female forms to trick and seduce mortals. (Hence their alternative name, Daedra/Dark Seducers.)

Web Comics
  • In Homestuck, troll reproduction is much closer to that of insects than humans (although they do end up looking humanoid). Nonetheless, the adult troll females that we eventually "see" do possess breasts. Author Andrew Hussie responded to this trope by saying that the readers shouldn't be so sure that they actually know what the biological purpose of trolls breasts is.
    • Similarly, the Carapacians are living chess pieces with Ken-Doll crotches, but the Queens still have boobs, as do some of the female Pawns.
  • Hala River from Irregular Elis is an alien with breasts.
  • When Gabe, in Penny Arcade, gleefully remarks that an up-coming video game may feature boobs, Tycho gently admonishes him for thinking so pedestrian: "Imagine a Chik'thar hive maiden scuttling out of her mottled carapace. Her inviting, transluscent thorax heaving with ripe larvae. She retracts her guard plates, where forty alien breasts bristle with nipples... (eyes glaze over) Yes, yes, a thousand times yes..."
  • Lampshaded in the Sluggy Freelance arc "Years of Yarncraft", when Zoe points this out to Torg, Torg tells Riff how to tell which of the slimeblobs are female. Yep, it's boobs.
  • Dragons from Draconia Chronicles have a noticeable pair of bulges on their upper torsos. However, they're clearly beneath their hides. The author states they're actually "flight muscles".
  • The Non-Adventures of Wonderella parodies the Most Common Superpower when, in a reboot, everybody gets mammoth mammaries. Including featureless luminous spheres.
  • Lavender from El Goonish Shive, is a member of a One-Gender Race of shapeshifting aliens but chooses to appear as a tall female with large breasts. It's hinted that she's in love with and is trying (unsuccessfully) to seduce her human boss.
  • Awful Hospital has Molly (an ambulatory bag of biological waste), Tori (a circulatory system in a humanoid shape), and BBQ Girll (an anthropomorphic grill) have chest bumps that may or may not represent breasts. What's weird is that none of the other female characters (aside from the human protagonist) have any human physical traits, let alone recognizably feminine traits, so it's anyone's guess why these three adhere to this trope. BBQ Girll at least was designed to resemble a knock-off fast food mascot.

Western Animation
  • Ben 10:
    • In the What If? episode "Gwen 10", some of Gwen's female versions of the aliens have busts. Including the one that's essentially made of gemstone. This is even weirder, given than Gwen herself had yet to hit puberty. (The aliens Ben transforms into also seem way past puberty.)
      • Another Omnitrix-wearing version of Gwen shows up in Omniverse. Since she's only a year older, most of this Gwen's aliens don't appear much more physically developed, with the exception of Wildvine, who possesses noticeable breasts despite being a) eleven, and b) a plant.
    • Green-Skinned Space Babe Xylene, who sports an impressive set. She mentions that her species hatches from eggs. OK, maybe she's a Monotreme and would nurse them afterwards. Oh, but then she says that parents of her species do not take care of their offspring at all. Really?
    • Myaxx is pretty well endowed, seeing as her species seems to be extremely Squidlike.
    • Omniverse introduced a villainess named Subdora, a member of a race of vaguely anthropomorphic( Subdora herself being more humanoid than the other members of her species seen on screen), three-eyed salamanders. Not only is she fairly well-endowed for a salamander, she also wears a midriff-baring top which reveals that she possesses a navel.
  • South Park:
    • Parodied in the Heavy Metal tribute, appropriately entitled "Major Boobage." Everything in the various dream sequences sports an impressive set of breasts, complete with nipples. There are ostrich-things with breasts, planets that are disembodied breasts, and a trio of trolls with huge breasts growing out of their shoulders. The kicker? There is exactly one human woman — "and you never really get a good look at her boobs". Only her boobs were censored.
    • Mr. Hankey's alcoholic wife (who is Talking Poo) has breasts, which she seems quite eager to show them to people. Once, in an argument, Mr. Hankey says that everyone can tell they're silicorn.
  • There is the Drawn Together twist ending parodying the first "Superman" movie, where Captain Hero changes history — and the evolutionary timeline — to make everyone boob-monsters that go around saying "Boob," Pokémon-style.
  • On Gargoyles, the title species comes in a variety of shapes from vaguely reptilian to mammalian, but females always have breasts. Word of God claims that however they look, gargoyles belong to their own class of animals called "gargates" (which descended from dinosaurs or similar creatures), and while they lay eggs, females do nurse.

  • Jamba!'s ringtone mascot "Crazy Frog", a.k.a. "The Annoying Thing", sporting ambiguous but noticeable genitalia that caused some controversy when he began appearing in late night ringtone ads. When he first began appearing in music videos in the United Kingdom, a prominent black bar was used to censor his groin area. With the exception of the tailed frog, amphibians don't even have external genitals.

Anime & Manga
  • In Dr. Slump, Obotchaman, a robot created by Dr. Mashirito, appears to have a penis, as seen when Senbei attached Arale's head on Obatchaman's body. Peasuke ends up walking in on Arale changing clothes, leading him to temporarily believe Arale was transgender. In the remake Arale shows it to Senbe while her body and Obotchaman's were swapped for a repairing purpose.

  • The T. rex in Caveman really shouldn't have had external genitalia at all, although at least they only protrude slightly.

  • From the Not in Front of the Parrot page:
    A man was walking through a pet store when a parrot called for his attention. "Buy me, I'm a very interesting parrot!" The man stopped and asked "What's so interesting about you?" "I have no legs," said the parrot. "Well how do you stay on the perch?" the man asked. The parrot replied "I have a very long penis and wrap it around the perch!". The man did think this was an interesting parrot and bought it. One day the man came home from work and the parrot said "Your friend Harry was over today!" The man said "Really?" "He was hugging your wife!" The man asked for more information. "They were kissing!" The man asked for more info. "They took their clothes off!" Infuriated, the man demanded what happened next. The parrot responded "I dunno, I got a woody and fell off the perch!"

  • Discworld:
    • In Small Gods, a tortoise who's really the god Om is lifted into the air by a chelonicidal eagle, but persuades it to deliver it to a specific location rather than drop it on a rocky surface. Its method of persuasion involves a hard beak and a solid grip upon certain delicate pieces of anatomy... anatomy which, as a bird, the eagle wouldn't actually have. (At least, not externally where they can be grabbed.)
    • In the Annotated Pratchett File v9.0, there's a bad joke cited in the Moving Pictures section about a toad with a troublesomely yellow penis. In reality, for a toad even to have a penis would be far more troublesome than its coloration.
  • In Petty Pewter Gods, Garrett tells a nosy hustler that he controls Mr. Big's chatter by tugging on a concealed thread that's tied to the parrot's little bird balls. Justified because the only thing Garrett's really yanking is the hustler's chain.
  • In American Gods, Anansi tells a story of how he tricked a tiger into swapping its tiger's testicles for his own tiny little spider testicles.

Live-Action TV
  • In Farscape, when Chiana, in a fight with a Scarran, asks, "Hey, do Scarrans have mivonks?" and then kicks for them... then winces and hops around, having hurt her foot. It replies that they do, but they're on the inside, and obviously well-protected.
  • Doctor Who:
    • Commander Strax was made into a nurse as punishment for being a failed Proud Warrior Race Guy. This apparently extends to being genetically modified into being the perfect nurse, including the ability to generate "magnificent quantities of lactic fluid".
    • In "The Curse of Fatal Death", the Master, in league with the Daleks, has been given by them a pair of "Dalek bumps" which take the form of two gold metal hemispheres on his chest.

Films — Animation
  • A female animal with the male variant shows up in Ice Age 3: Dawn of the Dinosaurs- a female saber-toothed squirrel with pecs.
    • Scrat gets all the fur ripped off his chest, exposing two dots of nipple. Not only are there fewer nipples present than seems plausible for his species, which would presumably have large litters like other squirrels, but rodents' nipples are generally arranged in paired lines that extend forward from the groin to the chest, not one pair on the chest as in human males (and females). And male rats and mice don't have any at all.

  • Raunchy versions of Aristophanes' The Birds include lines about a rooster crowing when he feels his morning erection rather than the coming dawn. Some performances in ancient times illustrated this with a chicken-costumed actor sporting a Gag Penis.

Web Comics
  • Dreamwalk Journal: as noted above in the Insects section, it's about anthropomorphic insects and arachnids. All females have big boobs, all males have big external genitalia, and everybody gets to have sex with everybody else, including two visiting human women.
  • The Order of the Stick:
    • A graphic insult slung at Belkar by the kobold Oracle (Lickmyorangeballshalfling) caused a debate among fans about whether doing as he'd suggested would require invasive surgery.
    • A later strip has a lizardfolk note the mammalian-minded wardrobe of the gladiators' prison.
    Gannji: And I don't need your standard-issue loincloth, I've been walking around without pants this entire time! It's called a "genital sheath," look it up. Hey, while you're at it, look up "hemipenes," because you can suck both of my—
  • Sequential Art: Seemingly averted with Pip (although he does use tissues), but played completely straight with Liam the lion-furry king of not-Narnia, especially since he is naked literally the entire time.
