An alien species has a conveniently descriptive name based on their looks, behavior or [[IntelligentGerbil blatantly obvious]] [[HumanoidAliens evolutionary provenance]]. The species is [[ExactlyWhatItSaysOnTheTin exactly what it says on]] [[PlanetOfHats the hat]].

This can be:
* {{Justified|Trope}} in that the aliens are named by outsiders, although, as an intelligent alien species and possibly a sovereign alien nation you might want to inform the Earthlings that you do not much care for being referred to as Foul-Smelling Space Devils. However, sometimes the name can become an AppropriatedAppellation. Another version is that the aliens' species name is [[TranslationConvention automatically translated]] for human ears.
* [[InexplicableCulturalTies Inexplicably]] so if the aliens actually refer to themselves, if not as Foul-Smelling Space Devils, as Stinkdevilonians calling attention to the writer's inability to come up with an alien-sounding name or, alternatively, their {{anvilicious}} [[ShowDontTell approach to characterization]].

Goes very well with PlanetOfHats and SpaceRomans and might overlap with NamedAfterTheirPlanet if the naming convention extends to the homeworld as well. For some reason, felinoid and reptilian aliens are all but guaranteed to have a descriptive name.

Please note that this trope can be used by aliens on humans as well.

!! Examples:

[[foldercontrol]]

[[folder:Anime and Manga]]
* The alien protagonists from ''Literature/CatPlanetCuties'' get called Catians as they have cat ears and tails and their somewhat catlike behaviours.
* The alien enemies in ''Anime/GunBuster'' are simply called "Space Monsters" (or "Uchuu-kaiju" in Japanese).
* ''Manga/HeterogeniaLinguistico'': The werewolf names for various species are usually very literal translations: "Knowing Water" for {{slimes}}, "Big Jaws" for LizardFolk, "Furless Ones" for both humans and lizardmen. Lizardmen call werewolves "soft" and krakens "wetlegs".
* ''[[Manga/JojosBizarreAdventureJojolion Jojolion]]'' has the Rock Humans, otherwise perfectly-human-like beings with the ability to grow a skin of solid rock at will. They also have lifespans in excess of two hundred years, and 95% of them are Stand users. Closely related are the Rock Animals, creatures with all the traits of Rock Humans, but a non-humanoid form and animal-level intelligence.
* The aliens that appear in ''Anime/MobileSuitGundam00'' are given the name "Extra-terrestrial Living-metal Shapeshifters", or "ELS" (pronounced "else") by humanity. Whether the ELS even have a name for themselves is unclear; [[StarfishAliens they may not have an equivalent concept]].
* ''Anime/SpacePatrolLuluco'' gives us the Blackholeians (which have a black hole where their heads should be) and the Nothinglings, who come from a barren world and [[EmptyShell have no emotions]]. Oh, and [[Anime/KillLaKill the Life Fibers]].
[[/folder]]

[[folder:Comic Books]]
* Watchers, symbiotes (which were later given the name Klyntar) and Brood in Creator/MarvelComics.
* [[ComicBook/GreenLantern Guardians Of the Universe]] (Also called Oans, originally Maltusians).
* The rather aggressively expansionistic [[ComicBook/BlueBeetle Reach]].
* The observant Monitors of Creator/DCComics.
* Each and every anthropomorphic race in ''ComicBook/AlbedoErmaFelnaEDF'' are named after their taxidermic term from their species (Felines, lepines, rodents, etc). The reason for this is closely linked to the OntologicalMystery at the heart of the story.
* ''Franchise/WonderWoman'' [[ComicBook/WonderWoman1942 Vol 1]]: Ry'''korn'''ians are born from what looks like giant corn stalks, and the mobile males have corn-silk like fibers on their heads.
[[/folder]]

[[folder:Film - Animation]]
* ''WesternAnimation/AlienXmas'' features the Klepts, a race of aliens who steal both from each other and from different planets out of greed.
[[/folder]]

[[folder:Film - Live-Action]]
* While they likely do have an actual name for their species, the Prawns from ''Film/{{District 9}}'' were given their nickname because they resemble the small creatures. On top of that they are bottom-feeders and scavengers.
* The second ''Film/MenInBlack'' film has a gag where K is unsuccessfully fighting a particularly tough alien when J shouts to him "He's a Ballchinian!" K pulls down the alien's collar and reveals a scrotum dangling from his chin, which he promptly kicks.
** The [[HilariousOuttakes outtakes]] reveal that Creator/WillSmith went through several variations on "guy with his balls on his chin" before settling on Ballchinian.
** The Bugs from the first movie (and later the animated series) also count.
* ''Film/{{Prometheus}}'': Shaw and Holloway gave [[{{Precursors}} the]] [[AncientAstronauts Engineers]] their name because they were the ones who "engineered" (i.e. created) humankind.
* ''Franchise/StarWars'':
** The quite squid-like Admiral Ackbar is a Mon Calamari.
** The Nosaurians are really yes-Saurians.
** Sand People. They live in the desert.
*** Both the name "Sand People" and the alternative name "Tusken Raiders" are explained in the ExpandedUniverse.
* The Frost Giants from the ''Film/{{Thor}}'' film.
[[/folder]]

[[folder:Literature]]
* All over the place in the works of Creator/AlastairReynolds: Inhibitors, Nestbuilder, Pattern Jugglers, Shrouders, Scuttlers, Fountainheads, Musk Dogs, Smiling Ones, to name just a few.
* Creator/ArthurCClarke: The aliens in the ''[[Literature/TheSpaceOdysseySeries Odyssey Series]]'' are simply called "the Firstborn," since they are {{Precursors}}. The ones in ''Childhood's End'' are called the Overlords, because they're [[VichyEarth in charge of Earth.]]
* In the [[Literature/TheCulture Culture]] series, there's a race called the Affront who are sadistic. Justified though in that this is an insult they were called by other groups, which they [[InsultBackfire took as a compliment]] and [[AppropriatedAppellation appropriated]].
* Creator/MarionZimmerBradley's ''Literature/{{Darkover}}'' series has the Catmen, who are human-sized humanoid cats.
* The [[http://en.wikipedia.org/wiki/Pierson%27s_Puppeteers Pierson's Puppeteers]] in Creator/LarryNiven's ''Literature/KnownSpace'' stories have two heads on stalks that look like hand puppets, hence the name.
** Puppeteers have two throats with three sets of vocal chords each, and it's a RunningGag that a human hearing a Puppeteer say his actual name will describe it using a variant on the phrase "industrial accident set to music". Their word for themselves as a race is accordingly unpronounceable by humans, but it translates into English as "Citizens". However, when talking to the humans of Known Space, they appropriate the human term "Puppeteers" (which, as it turns out, is apt for more than one reason). It's not clear if the Puppeteers are having a joke, just using a human term because they figure "that's what humans are going to call us anyway," or are trying to avoid the unpleasant connotations of the more literal translation ("We are Citizens; you are not").
* Lampshaded in ''Literature/LastSonOfKrypton''. Luthor has been taken captive by space aliens who communicate to him using a universal translator. The aliens explain that it translates into whatever word he expects to hear. Thus: "As I referred to you before, you are a Terran. I am a bug-head. The creature who just addressed you is a vulture-face."
* The Lemurians of the ''Literature/{{Destroyermen}}'' series are man-sized sapient lemurs. [[JustifiedTrope This is specifically the titular humans' name for them]] (they also call them Monkey-Cats or just 'Cats, while the Empire of New Britain calls them Ape Folk). The Lemurians call themselves Mi'Anaaka, which just means "people".
* The Syclarians of ''Literature/StarfleetCorpsOfEngineers''. Would you believe they write their language in a circular fashion?
* Creator/JackMcDevitt's ''The Engines of God'' (part of his ''Literature/PriscillaHutchins'' series) has "The Monument-Makers", a now-extinct race that traveled throughout the local part of the galaxy, setting up giant statues and mysterious fake cities on isolated, uninhabitable moons, including Iapetus, one of Saturn's moons. [[spoiler: The real name of the Monument-Makers were the Cholais (meaning 'the Universal People', because the culture did not see itself as limited to just the one species), but this is not known until after the first novel.]]
** This is based on real-world archaeological naming practices for when we just don't have any way of knowing what the lost population called themselves. Hence the "Mound Builders," a set of related archaic societies that [[ExactlyWhatItSaysOnTheTin left lots of large constructed mounds]] in the parts of ancient North America they called home. Or the ancient Clovis culture, so named because their distinctive tools were found near the city of Clovis, New Mexico.
* In Creator/HarryTurtledove's ''Literature/{{Worldwar}}'', reptilian invaders calling themselves simply "The Race" are often referred to as "Lizards" by humans. They return the insult by calling humans "Big Uglies".
* In ''Literature/TheDarkSideOfTheSun'', the vanished Precursor race is known as 'The Jokers'.
* Both alien races in the ''Literature/EndersGame'' series: Buggers look like bugs, and piggies look like pigs. The resemblance is reasonably close in the case of [[BeePeople the buggers]], but not especially close in the case of the piggies.
** In later books, it's revealed that "bugger" is a vulgar, insulting way to refer to the species, and their official name is "the Formics" (based on the Latin "formicae", meaning "ants"). The term "piggies" is more affectionate than insulting, but they likewise are officially referred to as "the Pequeninos" (Portuguese for "the little ones").
* In ''Literature/{{Animorphs}},'' [[OmnicidalManiac the Howlers]], who have a [[SuperScream horrible scream]] that incapacitates others, especially sentient species. {{Justified}} because they were created by [[CosmicHorror Crayak]] and probably have no real culture of their own, making them named by him or others whom they've come in contact with.
* In ''{{Literature/Remnants}},'' the human characters name the species they come in contact with inside [[SapientShip Mother]]. The "Blue Meanies" wear a dark blue space suit when first introduced; they actually call themselves the Children (of Mother herself). There's also the Riders, so named for the hoverboards they ride, the Squids (which maintain Mother), and the Shipwrights (StarfishAliens who created Mother).
* The [[NamesToRunAwayFromReallyFast Babyeaters]] in [[http://lesswrong.com/lw/y5/the_babyeating_aliens_18/ The Baby-Eating Aliens]].
* Two-way example in ''Literature/{{Honorverse}}''. Treecats look like six-legged cats who mostly live in trees, which is why they're called that(treecats refer to themselves simply as "People"). ''We'' are called "two-legs" by them.
* The Incredibly Deadly Viper from ''Literature/ASeriesOfUnfortunateEvents''... [[NonIndicativeName is not actually deadly at all]]. It is very friendly, and Uncle Monty named it this way to prank his colleagues while he introduces this new species of snakes to them. Unfortunately, it makes things harder when [[spoiler:Monty gets murdered by Count Olaf & his lackies, then frame the Incredibly Deadly Viper for it]]. [[AdultsAreUseless Mr. Poe]] is reluctant to believe the Baudelaire's claims that the Viper is innocent because he finds Monty's choice of name for it to be too counterproductive if it's supposed to be a joke name.
* The Sackers from the Star Trek novel ''Literature/TheThreeMinuteUniverse'' were named because their bodies looked like roughly human shaped [[BrownNoteBeing bags of disgusting with translucent skin]]. They kept the name because the race as a whole considers nicknames an honor, especially if they come from an alien race. Near the end of the book the species name for themselves is revealed: Vinithi.
* [[BrainsAndBrawn Carialle and Keff]], in ''Literature/TheShipWho Won'' like to name newly-discovered alien species in often idiosyncratic or referential ways. Having encountered a vaguely grasshopper-like race which communicates primarily by [[{{Gasshole}} "sharp poots out the rectum"]], Keff dubs them the "Beasts Blatisant".
[[/folder]]

[[folder:Live-Action TV]]
* Each of the aliens in ''Series/AlienWorlds2020'' is only given a generic title that broadly describes what it is or what it does (resulting in two completely unrelated aliens being called "predators"). The skygrazers are aliens that graze... in the sky, the pentapods are aliens which have five feet, the spiny blob-like bottom-feeders are called scavengers, the grubs are grub-like aliens, and so on.
* ''Series/DoctorWho''
** Sea Devils, who sometimes call themselves that despite the name having been coined by humans.
** Adipose are made of body fat, also known as adipose tissue.
** The Abzorbaloff. Absorbs people (in fairness that's an AppropriatedAppellation).
** Terry Nation had a habit of doing this with his ''Series/DoctorWho'' stories. To give two examples (both from ''The Chase'') the planet Aridus is a desert world and the planet Mechanus is inhabited by robots.
*** Aridus and Mechanus are extreme examples, since Aridus was once a lush world and Mechanus wasn't supposed to be taken over by the Mechanoids. One ''Magazine/DoctorWhoMagazine'' article referred to "the charming habit human colonists have in Terry Nation stories of naming planets after what's going to happen to them."
** The firey (Pyro) villains (Vile) of "The Fires of Pompeii" are the Pyrovile.
** The Cybermen of course. Alien Humans who became cyborgs.
** The Daemons encountered by the Third Doctor. Justified in that they inspired ideas of demons.
** The reptilian Draconians.
** The Forest of Cheem, tree-people.
** The Futurekind are a variant of humans from JustBeforeTheEnd of the universe.
** Blood-drinking Haemovore.
** Ice Warriors. This is another name humans came up with.
** The Cheetah People in ''Survival''.
** The Cat People in "New Earth" and "Gridlock".
* ''Franchise/StarTrek'' used to be very fond of this and typically falls to the "inexplicable" side.
** The Romulans and Remans come from Romulus and Remus, respectively. When they're introduced in the {{Prequel}} show ''Series/StarTrekEnterprise'', the uneducated crew of Enterprise is apparently not surprised that those aliens are named for mythological figures from Earth. The prequel could have easily turned this trope around by having humans name the Romulans "Romulans". And yet when Hoshi mis-translates the name as "Romalin", T'pol corrects her. Non-canon novels establish that both the Romulans and the Vulcans actually have different names.
** Avoided by retcon for the Klingon homeworld whose spelling was changed from "Kronos" to "Qo'noS" to imply that it just happens to sound similar to the child-eating titan from Earth mythology.
** The Grazerites from Grazer have evolved from grazing animals. Yes.
** The Saurians from Sauria look like dinosaurs.
** The Caitians from Cait are [[BeastMan humanoid cats]].
** Denebian Slime Devils. Though since they're neither humanoid nor sapient, it's not like they have some other word for themselves.
** The Borg, who are, of course, cyborgs.
** ''Series/StarTrekTheNextGeneration''
*** In "Home Soil" the alien crystalline life form calls humans [[https://www.youtube.com/watch?v=LAlqp0_a0tE "ugly bags of mostly water."]]
*** The Bynars of who live in pairs. They also communicate between themselves in binary.
** ''Series/StarTrekDeepSpaceNine''
*** Odo's species are only known as either Changelings (because they can change their appearance) or Founders (because they founded the Dominion).
** ''Series/StarTrekVoyager''
*** The Hierarchy. Low-ranking Hierarchy individuals are not allowed to do anything out of the routine without consulting their superiors first.
*** The Swarm, though in that case it's because they are so xenophobic no-one knows what they call themselves.
** ''Series/StarTrekEnterprise''
*** We get to know the species that is the BigBad of Season 3 only as the Sphere-Builders, due to the huge spherical structures that they constructed to create the Delphic Expanse.
* Mocked on ''Series/{{Supernatural}}'': Dean comes across a new type of demon that no one has ever seen before, so Bobby says that Dean gets to name it. Dean calls them [[Music/JeffersonStarship Jefferson Starships,]] "because they're [[TakeThat horrible and hard to kill]]."
* ''Series/BlakesSeven''
** In "Project Avalon", the Subterrons live a subterranean existence. What ''they'' call themselves is anyone's guess.
** Justified with the Decimas in "The Web". They are a ServantRace genetically engineered to carry out ten functions.
[[/folder]]

[[folder:Mythology]]
* The unicorn's name is derived from the Latin words "Uni" meaning "one" and "cornu" meaning "horn", and it's a one-horned horse.
* The ''each-uisge'', a creature in Scottish mythology that is either another name for or similar to the [[OurKelpiesAreDifferent kelpie]], means "water horse" in Gaelic. It seems to be a horse and it lives in the water.
[[/folder]]

[[folder:Tabletop Games]]
* ''TabletopGame/{{Traveller}}'' alien races.
** Aslan: feline-like humanoids, named either for the Turkish word for "lion" or the character Aslan in ''Literature/TheChroniclesOfNarnia''.
** Vargr: wolf-like humanoids, named from the Old Norse word meaning "wolf".
** The K'Kree are a partial example. Their nickname is "Centaurs", because they appear very similar to the centaurs of Myth/GreekMythology.
** The Hivers live together in underground nests.
* ''TabletopGame/DungeonsAndDragons''
** The dinosaur-like Saurials in 2nd edition.
** Women who could turn into swans: Swanmays of 2nd edition.
** The dragon-like Dragonborns from 4th edition on.
** The misshapen Mongrelmen of 2nd edition.
** The living plant siege engines called Battlebriars.
** The shadowy, sneaking Dark Ones.
** The Devourers who eat souls.
** The Displacer Beasts, who can make themselves look like they were somewhere else.
** The telepathic, mind-controlling Mind Flayers.
** The speedy Quicklings.
** TabletopGame/{{Eberron}} has the Changelings who practice {{humanshifting}} and Shifters, who have a limited ability to shift forms inherited from lycanthropes.
* TabletopGame/Warhammer40000: the various Tyranid organisms' name were given by the Guardsmen fighting them. Hence Ripper swarms, Gargoyles, Carnifexes (butcher in fake Latin)...
** A lot of the larger tyranid organisms have Latin or Greek names - Dominatrix (female lord or controller), Haruspex (a priest who interprets entrails), Malefactor (criminal or wrongdoer), Dacytlis (fingered), Biovore (eater of living things), Zoanthrope (animal-man), Lictor (Roman magistral attendant)...
** Strangely used by the Tau in that their vehicles are all named after Earth fish (Piranha, Devilfish, Hammerhead...) and use Greek-letter callsigns.
*** Explained in the [[SplatBook codex]] as being Imperial ReportingNames, as the Tau's own naming scheme is [[TheUnpronouncable ridiculous]] and [[FantasticRacism alien]].
** The Eldar also count. They're space elves of a sort, and "Eldar" is Tolkien's term for the Elven race, which literally translates from Quenya as "people of the stars". Their Craftworlds also have a primarily Celtic theme to their names, to give them a mythological twist, while the Dark Eldar city is called Comorragh (= Gomorrah) to indicate the depth of their debauched culture. The twisted Haemonculus covens also work here, with Haemonculus apparently being a compound of haemo- ("blood" in Greek) and homunculus (a miniature person in alchemical lore).
** Also the Necrons, who are undead skeleton-robots with a name evocative of death in Greek.
* The races in ''TabletopGame/CosmicEncounter'' have been presumably named by each other rather than by themselves, giving us the Zombies, the Virus, the Seekers, the Philanthopists, the Macrons, the Void ... the names are related to how their racial power works (Zombies never go to the warp, Virus have the ability to multiply, etc.)
[[/folder]]

[[folder:Toys]]
* ''Franchise/{{Tamagotchi}}'' features several breeds of Tamagotchi that are named after the object they resemble, such as with Belltchi and Hoshitchi ("hoshi" being Japanese for "star"). This is actually the "outsiders naming them" variety; Professor Banzo and his assistant Mikachu named each species of Tamagotchi as they discovered them, naming them after Earth culture and objects. After returning to their planet, the Tamagotchis adapted the naming conventions given to them, as well as [[AliensSpeakingEnglish the language spoken by humans]].
[[/folder]]

[[folder:Video Games]]
* The Ravagers of ''VideoGame/EarthDefenseForce2017'' and ''VideoGame/EarthDefenseForceInsectArmageddon''. Amusingly, they were dubbed Ravagers before their penchance for ravaging became apparent.
* Contrary to what their name might suggest, ''Franchise/{{Metroid}}'''s {{Space Pirate}}s are not simply a band of space-faring pirates but a full-blown [[PlanetOfHats species]]. Though they are never shown speaking, they even seem to refer to themselves as "Space Pirates" in their logs, ([[TranslationConvention though this may just be Samus's suit translating anyways]]). They ''are'' lead by a space dragon, a giant brain, and a colossal space lizard, all of whom may or may not have a biological relation to the Space Pirate {{Mooks}}.
** It can perhaps be said that the Space Pirate organization is primarily made up of one species (who are referred to in some materials as "Zebesians", though their homeworld as seen in ''Prime 3'' is definitely not Zebes), and they are accepting of like-minded individuals from other species. One of the other "Pirate species" shown are named the "Kihunters".
** Ridley is the only member of his species seen, but it is mentioned that he is a Space Dragon.
** Even the Chozo, in Japanese: "choujin-zoku" means "birdman race". Chozo look like humanoid avians.
* In the ''VideoGame/{{Myst}}'' sequel ''VideoGame/{{Riven}}'', the creatures called wahrks are [[MixAndMatchCritters a mixture of whales and sharks]]. It's implied that this name for them was developed independently by a race who had never heard the English language.
* ''Franchise/MassEffect'':
** Collectors, Reapers, and Keepers. It should be noted that none of the three species call themselves the names; Collectors and Keepers don't speak and Reapers disdain the title given to them:
--->'''Sovereign:''' [[foldercontrol]]

[[folder: "Reaper". A label created by the Protheans to give voice to their destruction. In the end, what they chose to call us is irrelevant. We simply... are. ]]

** The Collectors and Keepers are named as such by the Citadel races [[spoiler:and are species modified by the Reapers to serve as their aids in reconquering the galaxy. Even worse, the Collectors used to be the [[{{Precursors}} Protheans]] before the Reapers defiled them and the last few survivors of their race were the only reason Shepard was able to beat Sovereign via HeroicSacrifice]].
** A WalkingSpoiler example from the third game are [[spoiler:the Leviathans. They don't seem willing to share the true name of their species with the rest of the galaxy, so everyone winds up calling them "Leviathans", as they are large aquatic creatures that live in very deep oceans.]]
* [[InsectoidAliens The Hivers]] in ''VideoGame/SwordOfTheStars'', which is a name used by humans and not by the species itself (their name, translated to English, means "The Children"). Also, the Zuul, who are a descriptively named species in Liir speech: The word is a root of the Liir term for "abominable". The Zuul have no name for themselves, their telepathy doing odd things to their sense of personal identity, and probably don't care what others call them.
** They do care. They would like to be called "Masters".
* The Paranid race in the ''[[VideoGame/{{X}} X-Universe]]'' is a clear pun on "para''noid''". While not exactly paranoid, they are severely xenophobic. The Splits are a highly fractious and aggressive race that is often embroiled in civil wars. Xenon is derived from the word "xenomorph" (fancy term for "alien lifeform"), and the shortened form "xenon" used to be slang among the Argon for any alien species, but over time it came to refer to the Xenon exclusively.
* The various Covenant enemies in ''Franchise/{{Halo}}'' are either named after their military roles ([[{{Mooks}} Grunts]], [[EliteMooks Elites]], [[OneManArmy Hunters]], [[GadgeteerGenius Engineers]], [[TribeOfPriests Prophets]]) or their overall demeanor ([[SpacePirates Jackals]], [[InsectoidAliens Drones]], [[TheBrute Brutes]]). In their native tongues, they have their own names, but these were never used in-game until ''VideoGame/Halo5Guardians'', possibly as a result of TranslationConvention.
* The dragon-like Dracons of ''VideoGame/{{Wizardry}}'' games. The rat-like Rattkins count as well as the feline Fel''purr''s, the canine Ra''wulf''s, and the '''T'''a'''ran'''tula-like T'Rang.
* You get a lot of these with the various ''{{VideoGame/XCOM}}'' games. Snakemen and Vipers are obviously SnakePeople, while Thin Men are NoodlePeople. Cyberdiscs resemble a miniature FlyingSaucer. Floaters, um, float. Lobstermen resemble lobsters and Silacoids look like weirdly aggressive rocks. Interestingly, the [[spoiler:High Ethereal]] use these human-given names for the various aliens, rather than any of their own.
* The four main races in ''VideoGame/TerraBattle'' are the Humans, Beastfolks, Lizardfolks, and Stonefolks. Beastfolks are LittleBitBeastly people. Lizardfolks are, well, LizardFolk. Stonefolks are people made out of, you guess it, stone.
* This is true of most of the species in ''VideoGame/{{FTL}}''. Perfectly matched for the mantis, slug, and rock species. A bit more of a stretch but still pretty spot-on for the engi (short for "engineer"). Really the only one that doesn't fit is the zoltan.
* Most alien species in ''VideoGame/{{Starbound}}'', with playable races including [[KillerGorilla Apex]] (former HumanAliens who devolved back into ape-like forms in exchange for greater brain power), [[BirdPeople Avian]] (humanoids resembling wingless birds), [[PlantAliens Floran]] (sapient, mobile carnivorous plants) and [[RidiculouslyHumanRobots Glitch]] (machines built to simulate evolution of society, stuck in MedievalStasis due to [[ExactlyWhatItSaysOnTheTin a glitch]] in their programming). Other species include: Penguins (sapient space penguins), [[BadassAdorable Alpaca]] (ProudWarriorRace of alpaca-like space centaurs), [[LivingShadow Shadows]] (living shadows), [[FrogMen Froggs]] (frog-like ProudMerchantRace) and Fennerox ([[FoxFolk humanoid fennec foxes]]).
* Justified in ''VideoGame/{{Subnautica}}'' and ''Subnautica: Below Zero''. The PDA automatically generates a simple, descriptive name for any scanned species that doesn't appear in its database. This results in, for example, fish with large side-facing eyes being called "Peepers", shark-like creatures that burrow into sand being called "Sand Sharks", and so on.
[[/folder]]

[[folder:Webcomics]]
* Subverted in ''Webcomic/{{Starslip}}'': the ship visits an alien race called the Oculons, who have no eyesight. Vanderbeam bemoans the irony of their name considering they can't see, and one of them tells him, no, that's not what they call themselves, humans just named them that because their planet looked like a giant eye.
* ''Webcomic/SchlockMercenary'':
** An amphibious species called the Tohdfraugs.
** Schlock is a "carbo-silicate amorph". In this case, it kind of makes sense, because his species didn't evolve naturally and give themselves a name; they were originally data storage units that happened to spontaneously gain sentience (in a very literal sense, Schlock is all brain).
** The Uniocs. {{Discussed}} when Kevyn asks why the Uniocs were called that, rather than "Oth-ers" upon hearing that their name for their homeworld is "Oth". Turns out, they wanted to be called "one-eyes", and not "strangers".
** The [[http://www.schlockmercenary.com/2002-12-16 Tetrisoids]]. Their body structure consists of a head with four limbs (apparently adapted for locomotion and manipulation) arranged tetrahedrally.
* ''Webcomic/TheLawOfPurple'' has the Nekojin, a race of cat people.
[[/folder]]

[[folder:Web Original]]
* ''Website/OrionsArm'' has several examples:
** Meistersingers are tree-like intelligent creatures that consist of the "Meister" (the main tree) and its "choir" of attendant animal-like lifeforms that it controls via "singing".
** Hildemar's Knots (presumably named after the person who discovered them), which are, well, intelligent "knots" that live on the surfaces of a cluster of neutron stars. They don't appear to have names among themselves, and communicating with them at all is difficult due to their [[StarfishAliens extremely different perception of the universe]] causing them to view anything beyond the surface of their neutron star to be abstract mathematical concepts.
** Angel Hairs, an UpliftedAnimal from a gas giant ecology, are made up of extremely long floating strands.
** The Jacks, so named because no one's sure if they are extinct or not; they keep unexpectedly "popping up" on different worlds like a Jack-in-the-box, over the course of thousands of years.
[[/folder]]

[[folder:Western Animation]]
* Both alien species and individuals in ''WesternAnimation/{{Ben 10}}'' have descriptive names, for example, Galvanic Mechamorphs for Upgrade's species, Vulpimancers for Wildmutt, and Florauna for Wildvine.
** Two more notable examples are when it turns out that the nickname Ben gave his forms is actually spot-on for the actual species name, translated from DogLatin. Fourarm is an example of a Tetramand, a species whose most notable trait is that they [[MultiArmedAndDangerous have four arms]]. Likewise, there are Arachnosimians, who look [[MixAndMatchCritters half spider, half-monkey,]] which Ben called Spidermonkey.
* The lobster/crab-like Decapodians of ''{{WesternAnimation/Futurama}}''.
** There would actually be quite a few examples: the Amphibiosans (amphibians), the Brain-Spawn (floating brains), the Amazonians (an OneGenderRace of gigantic women), etc. The Nibblonians also sort of count, using that name on the grounds that they're "like Nibbler." (Presumably, they have their own name that would take longer than the age of the universe to pronounce.)
** "Into The Wild Green Yonder" has the (unsurprisingly) extinct [[http://1.bp.blogspot.com/_PRRPoq6UGlM/TA6ZuJhE9PI/AAAAAAAABC4/eIhr2WYR418/s400/SBT.png striped biologist taunters]], [[ExactlyWhatItSaysOnTheTin striped animals that taunt biologists]].
---> ''What are you gonna do? [[TooDumbToLive Shoot us]]?''
* ''WesternAnimation/ThunderCats2011'', despite being set on an alien planet, simply calls its BeastFolk by obvious names: {{Cat|folk}}s, {{Dog|faces}}s, {{Lizard| Folk}}s and so on, but gets a bit more creative with more fantastic races, like [[PlantPeople Petalars]], [[OurGiantsAreBigger Giantors]] and {{Cute Machine|s}} [[BearyFriendly teddy bears]] the Ro-Bear Berbils.
* ''WesternAnimation/InvaderZim'' gives us the [[NamesToRunAwayFromReallyFast Slaughtering Rat People]] of Blorch, the planet where [[ButtMonkey Skoodge]] was sent.
** The ''Irk''ens themselves, by way of a StealthPun. ([[WhatCouldHaveBeen An earlier pitch]] used a variant where Zim was "a Noyng.")
** PlayedForLaughs in the comic continuation:
-->'''Ubertrouser:''' The name of my kin is inconceivable by your language.
-->'''Dib:''' How about "[[LivingClothes Space Pants]]?"
-->'''Ubertrouser:''' Oh wait, no, you got it. We are "''the Space Pants!''"
* ''WesternAnimation/EarthwormJim'' has the Planet of the Easily Frightened People.
* The [[OctopoidAliens Octaliens]] from ''WesternAnimation/MiloMurphysLaw.'' One of the inexplicable examples, since [[NamedAfterTheirPlanet their homeworld is named Octalia]] and they explicitly aren't AliensSpeakingEnglish (unless "Octalia" is something their TranslatorMicrobes came up with).
[[/folder]]

* A lot of the scientific names given to animals follow this trope. This is more obvious in extinct animals since those don't get to 'hide' behind a common name. Examples include Triceratops (three-horned face) and Ctenochasma (comb jaw). It should, however, be noted that most of these names are given based on outstanding features compared to related animals, [[ScienceMarchesOn thus many names become less telling once it turns out that the animal is related to a ridiculous amount of animals that share said 'unique' feature.]]
* This was a common thing in ancient Egypt where, among other examples, their name for "cat" was "mau" and their name for "donkey" was "A" (the way they onomatopoeic the donkey's sound, which we write out as "hee-haw"). It's basically as if they approached these animals, asked "pardon me good sir, but what are you?", the animal made a sound, and they said, "very well then!"
* There's also the anteater. We're pretty sure you can guess why it's called that.
* The most famous example is probably the octopus, "octo" being Greek for "eight" and "pus" for "feet". Similarly, the class octopi belong to, Cephalopoda -- "cephalo" for head and "pod" for foot (also in Greek). This alludes to the fact cephalopods are basically heads with several feet attached.
