->''They were mostly shiny and slippery, but the ridges of their backs were scaly. Their forms vaguely suggested the anthropoid, while their heads were the heads of fish, with prodigious bulging eyes that never closed. At the sides of their necks were palpitating gills, and their long paws were webbed.''

Fish People are a specific category of (usually) intelligent, underwater fantasy species. While they're humanoids (one head, two arms, two legs), they don't look human at all; their bodies, especially the faces, have a fish-like/reptilian appearance. This means that [[OurMermaidsAreDifferent mermaids]] are not true Fish People, at least not the kind described here. Neither are more [[ApparentlyHumanMerfolk human-like sea dwellers]] such as ComicBook/{{Aquaman}} or Namor the ComicBook/SubMariner. A Fish Person's CharacterAlignment and ability to survive on land vary depending on the character and the work.

While Fish People are most often a pre-existing race, sometimes they are former humans (or fish) who are the result of [[{{Mutants}} mutation]]. This origin seems especially prevalent in WesternAnimation.

[[OurMermaidsAreDifferent Merfolk]] can have a similar style, but fail the critical "has legs" check... most of the time. Since many Fish People appear somewhat reptilian, LizardFolk and ReptilesAreAbhorrent are also related tropes. Expect them to create breathtaking [[UnderwaterCity Underwater Cities]].

Fish People are a subspecies of PettingZooPeople. SuperTrope to SharkMan.


[[folder:Anime & Manga]]
* The myeterious, barely-glimpsed Water Folk from ''Literature/MoribitoGuardianOfTheSpirit''.
* The Fishmen from ''Manga/OnePiece''. Their sister species are the Merfolk, traditional mermaids. The two species get along pretty well and can even interbreed, but the Fishmen tend to be more aggressive and angry towards humans while the Merfolk are light-hearted and naive. Also Fishmen are [[SuperStrength 10x stronger than humans from birth]] and both types can [[MakingASplash use water as a weapon]].
* One of the many denizens found in the Magic World of ''Manga/MahouSenseiNegima'' is a dolphin man. A trucker dolphin man. With flippers for hands. How he is able to hold things like the postcard from [[spoiler:Makie and Yuuna]] without fingers, we may never know.
* ''Anime/MazingerZ'': The Chip Kamoy ("divine fishes" in Ainu idiom). They showed up in the Gosaku Ota manga, and they were a race of gigantic, bipedal, humanoid maneating fishes from another dimension who raised herds of humans as if they were cattle. Their bodies were scaly and covered with fins. However, they had depleted their homeworld's natural resources and were running out of food, so they crossed over to our dimension to find more prey.
* ''LightNovel/{{Slayers}}'' pokes fun at this trope -- the standard fishman in Lina's world is basically a giant fish with stick-thin limbs.
* ''Manga/{{Naruto}}'':
** During the Land of the Sea filler arcs, [[MadScientist Amachi's]] ambition is to create the perfect aquatic soldier, transforming humans into Fish People. [[GirlOfTheWeek Isarabi]] was a partially successful trial run, but could not fully switch back to human form. Amachi made himself into a perfect hybrid, but ultimately discovered that without any skills other than becoming scaly, he wasn't the ultimate warrior he'd hoped.
** Kisame and Fuguki (Samehada's previous owner) both look very much like a shark and a puffer fish, but they're apparently just weird looking humans [[spoiler:except when fused with Samehada.]]
* ''Franchise/{{Digimon}}'' has a few of these. The most notable one is Hangyomon/Divermon, who despite being one of these, [[FridgeLogic needs a diving mask and scuba tank while underwater.]] Other examples include the amphibion-like Ranamon from ''Anime/DigimonFrontier'', the squid-esque [=MarineDevimon=], the aptly named Orcamon and Coelamon, and whatever the hell [[http://dma.wtw-x.net/dexsurfi.shtml Surfimon]] is.
* Sky-Byte from ''Anime/TransformersRobotsInDisguise'' is this combined with a TransformingMecha.
* The BigBad of ''Anime/BlueSubmarineNo6'', Dr. Zorndyke, floods the earth in an attempt to wipe out humanity and replace it with his own races of genetically engineered PettingZooPeople, the most numerous of which are the aquatic varieties. Not surprisingly, all of the females are CuteMonsterGirl 's, ''especially'' the mermaids.
* People with fish for heads (yes, that's right, ''fish for heads'') from another planet are shown in act 47, in the fifth arc of the ''Manga/SailorMoon'' manga. They can be seen [[http://www.youtube.com/watch?v=-ixdkIOhwVE here at about 3:36.]]
* Zed O'Brien of ''Manga/BloodBlockadeBattlefront'' is a fishman very much in the Abe Sapien mold, with legs and human limbs but a fishlike face. Having gills, he breathes through the use of a water-containing apparatus that he wears around his neck.

[[folder:Comic Books]]
* Abe Sapien from the ''ComicBook/{{Hellboy}}'' comic and its adaptations in other media. The series also has the frog monsters as a recurring enemy, an {{Expy}} of Lovecraft's Deep Ones.
* Triton from the Franchise/MarvelUniverse.
** Some of Namor's enemies are Fish People, like Tiger Shark (or whale people in Orca's case) and most of the people from {{Atlantis}} ''almost'' count as Fish People. Namor is a mutant, however.
*** His second wife Marrina was even closer.
*** Atlanteans in ''ComicBook/{{Invincible}}'' are a parody of this. Marvel and DC both have ApparentlyHumanMerfolk, or very close to it. ''Invincible's'' Atlanteans live like the Atlanteans of Namor and Aquaman - the ThemeParkVersion of a feudal society, SchizoTech, frequent problems with {{Kaiju}}, and a king who unaccountably spends a lot of time on land as a superhero - but they are ''definitely'' Fish People, not apparently human.
* Lagoon Boy from the Franchise/DCUniverse...
** ...and his probable DistaffCounterpart, Gill Girl from ''ComicBook/TeenTitansGo''
** Then there's Triton from the ''WesternAnimation/TeenTitans'' animated series, and Aqualad's little Mechanic friend Tramm.
* In ''ComicBook/SwampThing'', a new generation of vampires are hatched in a town submerged in stagnant water that have the form of fish people (though closer to fish). Charmingly, they eat each other until only one huge newborn remains.
* The Waterlogged Warlock from ''ComicBook/{{Abadazad}}''.
* Nessie from ''ComicBook/{{Boneyard}}''.
* The Creator/TangentComics version of the Sea Devils. There's at least six or seven different species, from shark people to shrimp people, and some racial strife between them.
* Man Ray, a.k.a. Ray Fillet in the Franchise/ArchieComics ''ComicBook/TeenageMutantNinjaTurtlesAdventures''.
** [[http://turtlepedia.wikia.com/wiki/Armaggon_%28Archie%29 Armaggon]] as well, a mutant humanoid shark.
** The Merpeople from the [[ComicBook/TeenageMutantNinjaTurtlesMirage Mirage comics]]. They also appear in the [[WesternAnimation/TeenageMutantNinjaTurtles2003 2003 cartoon]].
* King Shark, former Aquaman and ComicBook/{{Superboy}} villain, one-time member of the ComicBook/SecretSix, and in the ComicBook/{{New 52}}, a member of the ComicBook/SuicideSquad. But don't call him a fish person! He is a shark! [[InsistentTerminology A SHARK!]]
* Fishy Pete from ''ComicBook/TheGoon''.
* A more literal example is ''ComicBook/FishPolice''. The characters have fish-like faces, and mermaid-like bodies (humanlike upper half, fish tail for lower half) despite being fish through-and-through.
* Kiro, from Marvel's ''Franchise/StarWars'' comics.
* In Creator/DCComics' ''ComicBook/LooneyTunes'' title, Lola Bunny has a BurgerFool job with Machu Pizza, where she specializes in delivering food to AliensAndMonsters. One story has her delivering pizza to an UnderwaterCity populated by Fish People.
* A Deep One appears in Creator/AlanMoore's ''ComicBook/{{Neonomicon}}'' mini-series, based on Lovecraft's lore (and, as is common with this trope, a woman is raped by it).
* ''ComicBook/EmperorJoker'': ComicBook/TheJoker uses his godlike RealityWarper powers to turn Aquaman into an actual fish man supervillain who ironically enough hates the ocean and tries to keep everyone out of it.

[[folder:Fan Works]]
* In the ''Anime/NeonGenesisEvangelion''[=/=]Creator/HPLovecraft FusionFic ''Fanfic/ChildrenOfAnElderGod'': [[spoiler:Ritsuko]] gradually transforms into [[http://lovecraft.wikia.com/wiki/Deep_One a Deep One]] from the Franchise/CthulhuMythos, resembling a humanoid fish with lanky, scrawny, human-like limbs, gills, fins and tail, and she loses the capability to breathe air.

[[folder:Films -- Animation]]
* The Missing Link from ''WesternAnimation/MonstersVsAliens'' is a Film/CreatureFromTheBlackLagoon-esque fish-man.
* The Film/CreatureFromTheBlackLagoon and his daughter made a cameo at the end of ''WesternAnimation/ScoobyDooAndTheGhoulSchool''.

[[folder:Films -- Live-Action]]
* The UrExample is probably the 1929 film version of Creator/JulesVerne's ''Literature/MysteriousIsland'', with some really UglyCute [[http://3.bp.blogspot.com/-b6OYnb9cnPY/Uu-XlUz5W8I/AAAAAAAAZUo/SrBg3QV_Idw/s1600/1929c.jpg undersea beings.]]
* The ''Film/CreatureFromTheBlackLagoon'' (a.k.a. the Gill-Man), pictured above, is probably the most famous ([[FountainOfExpies and imitated]]) Fish Person, and certainly the TropeCodifier for movies. He starred in three films -- the self-titled first movie and its sequels ''Film/RevengeOfTheCreature'' and ''Film/TheCreatureWalksAmongUs''. He's become one of the Franchise/UniversalHorror monsters, allowing him to co-star in [[SpinOff Spin-Offs]] and [[TheMerch merchandise]] with {{Dracula}}, FrankensteinsMonster and [[Film/TheMummy1932 The Mummy]], among others.
* ''Franchise/StarWars:''
** Kit Fisto from the prequels, though he's a bit of a [[http://starwars.wikia.com/wiki/File:Nautolan_NEGAS.jpg squidman.]] Also in his earlier appearance in ''Film/MenInBlack''.
** Gungans, including the notorious Jar Jar Binks. Though they're more amphibian people.
** In the original trilogy, [[PunnyName Mon Calamari]] like Admiral Ackbar ([[MemeticMutation "It's a TRAP!"]]) and [[http://starwars.wikia.com/wiki/Mon_Calamari this dancer]]. It seems odd, but they can squeeze those hands and feet into human-shaped boots and gloves as needed. From the same planet we get the [[http://starwars.wikia.com/wiki/File:QuarrenNEGAS.jpg Quarren]], who are [[{{Cthulhumanoid}} even more squidlike]] than Kit.
** The Franchise/StarWarsExpandedUniverse has a number of [[http://starwars.wikia.com/wiki/Category:Aquatic_sentient_species aquatic sentients]], most of whom are fishy in nature. One of them, the Rakatan species (who even bear a passing resemblance to Mon Calamari), were the very first galactic superpower in the ''Star Wars'' universe, reigning even over the primitive humans of Coruscant 30,000 years before the events of the original 1977 film as part of their "Infinite Empire."
* ''Film/GodzillaVsHedorah'' has [[BigLippedAlligatorMoment a VERY odd and out of place scene]] where a man pictures humans with fish heads. It makes no sense at all, and is never mentioned again.
** The character was in a bar and appeared to have been drinking to excess. He was hallucinating, but then again, this was TheSeventies.
* In ''Franchise/PiratesOfTheCaribbean'', Davy Jones and his damned crew steadily mutate into these over the decades of service on the Flying Dutchman. Except the disobedient, who become more coral-like, and end up fused with the ship itself.
** It's not just the disobedient. The implication is that, by the time your hundred-year contract is up, you ''will'' be part of the ship. One of the crew has the next helm growing out of his spine.
** This has more to do with Jones's bitterness towards Calypso than the ship itself, however - when [[spoiler:Will]] replaces him as captain in [[Film/PiratesOfTheCaribbeanAtWorldsEnd third film]], [[spoiler: everyone on the ship [[NoOntologicalInertia spontaneously reverts to normal]]. Will then retains his humanity all the way through to his post-credits reunion with Elizabeth.]]
* Although we never see the title monster in ''Film/{{Cthulhu}}'', the protagonist does encounter these creatures in a pitch-dark tunnel beneath [[TownWithADarkSecret Rivermouth]].
-->''"There were ''things'', and they were everywhere! They were on the ground, they were [[CeilingCling on the ceiling]], they were everywhere!"''
* ''Film/{{Dagon}}'' (2001), an adaptation of Creator/HPLovecraft's ''Literature/TheShadowOverInnsmouth''.
* As mentioned above, Abe Sapien from ''Film/{{Hellboy}}''.
* ''Film/TheLastLovecraftRelicOfCthulhu'' has Starspawn and his pets as fish people; they're weakened from being away from the ocean. Also there was a curious "Half-Breed" show, probably offspring of one of the many rapings we hear about in the movie.
* Creator/RogerCorman gave us ''Monster'', aka ''HumanoidsFromTheDeep'', about a bunch of fish people who want to come ashore and, well, knock up the local gals. Oddly enough, this is something of a running theme in fish people-related horror stories.
* The MadScientist in ''Film/TheBloodWatersOfDrZ'' turn himself into this, he then kills his enemies and tries to find a woman to reproduce with.
* The monsters from ''Film/TheyBite'' are also Fish People who interrupt the shooting of a feminist porno movie while raping the actresses.
* 1979's Italian horror movie ''L'isola degli uomini pesce'' (Island of the Fish Men): the title says it all.
* One of the demons in horror BMovie ''Film/DemonsAtTheDoor'' is very similar to a Fishman, he also tries to rape a girl in the shower, as most Fishmen do in movies.

* The ''Literature/FightingFantasy'' gamebook world of Titan features the [[ExactlyWhatItSaysOnTheTin Fish Men]], a race created by an EvilutionaryBiologist sorcerer who blended a number of unwilling humans with fish. They tend to be solitary, cruel, and hostile to humans, attacking them with tridents when the humans intrude on their territory or simply to steal the humans' riches.

* UrExample: The titular character/monster in the [[Literature/TheKingInYellow Robert W. Chambers]] story "The Harbor-Master" is one of these; it's thought to have been the basis for...
* Creator/HPLovecraft's [[Franchise/CthulhuMythos Deep Ones]], first appearing in ''Literature/TheShadowOverInnsmouth'', are the TropeCodifier for literature and possibly Fish People in general.
* Michael Reaves and Steve Perry's novel ''Dome'' is set at a futuristic undersea research lab. One of its residents volunteers to be genetically modified into a fish person in order to better survive the underwater environment.
* David J. Schow's short story "Gills" features Manphibian, a CaptainErsatz of the Film/CreatureFromTheBlackLagoon who has entered ShowBusiness.
* ''Barlowe's Guide To Extraterrestrials'' depicts a Guild Steersman from ''Franchise/{{Dune}}'' as resembling this trope.
* A microscopic version of this trope appears in "Surface Tension", a short story by Creator/JamesBlish. A colony ship crashes on a planet virtually devoid of land, so they create (via genetic engineering) tiny aquatic humans to carry on their legacy after they've died.
* The Nartec in ''Literature/{{Animorphs}}''' "The Mutation".
* Emily Rodda's ''Literature/RowanOfRin'' books have a race of fish-people called the Maris.
* The Merlons from the Crystal Doors series of books.
* Oracle of Fnord in ''Literature/PlayPlaces''. Parodied when a councilman comments on the Oracle's "private scales".
* The {{Evilutionary Biologist}}s in Creator/JackChalker's ''Literature/TheMoreauFactor'' developed at least three species of aquatic {{Half Human Hybrid}}s: a race of fish people was one of them.
* ''Literature/TheScar'' by Crator/ChinaMieville has several aquatic races, most notably the Grindylow. Also the simply-named Menfish.
* The ''{{LightNovel/Slayers}}'' novels feature this too (obviously, since the anime was based of them). There are apparently several varieties of fish people of varying degrees of icthyism, but Nunsa, the one who appears in the first novel, takes the cake; talking and walking around on land are his only concessions to the "people" part of the trope. When Zolf tells him to kiss Lina to gross her out, he comments that he's considered the most desirable mate in his school (the [[IncrediblyLamePun best catch]], you might say), then sits down and waits patiently. When quizzed, he claims he's waiting for the eggs, since he's not sure what kissing is, but is vaguely aware it's related to mating.
* The Ralaloons in ''Literature/{{Spaceforce}}''.
* Marsh-wiggles from ''Literature/TheChroniclesOfNarnia''. [[http://narnia.wikia.com/wiki/The_Chronicles_of_Narnia_Wiki WikiNarnia]] describes them as having "green-grey straw-like hair, large ears, long legs and arms, webbed hands with long fingers...hard webbed feet, similar to those of ducks...a muddy complexion and greenish skin." Oh, and they're also [[PlanetOfHats an entire race of]] [[TheEeyore Eeyores]]--the only one we meet, Puddleglum, is seen as a WideEyedIdealist by his fellow Marsh-wiggles, and ''he'' has lines like:
-->"Those eels will take a mortal long time to cook, and either of you might faint with hunger before they're done. I knew a little girl—but I'd better not tell you that story. It might lower your spirits, and [[HypocriticalHumor that's a thing I never do]]."
-->"The bright side of it is, that if we break our necks getting down the cliff, then we're safe from being drowned in the river."
-->"And you must always remember there's one good thing about being trapped down here: It'll save funeral expenses."
** In his defense, he's a {{Determinator}} who manages to keep Jill and Eustace going, and the sole member of his group who remembers the quest when the others were distracted by promises of food and comfort from Harfang. He realized that [[TheVamp the Lady of the Green Kirtle]] and [[SuperFunHappyThingOfDoom the Gentle Giants of Harfang]] were not to be trusted long before his companions did. And he has several [[SugarWiki/MomentOfAwesome incredibly epic moments]], the most memorable being a ShutUpHannibal which proved that he ''wasn't'' always a complete pessimist.
* ''Literature/TheLaundryFiles'' combines The Franchise/CthulhuMythos with The UsefulNotes/ColdWar, and in keeping with the Mythos, has its own version of the Deep Ones (codename ʙʟᴜᴇ ʜᴀᴅᴇs). Just like the original, they can [[HalfHumanHybrid interbreed with humans]]. Also, their civilization predates humanity by several million years and has [[HigherTechSpecies technology to match]]. We take great care not to piss them off.
* The Fomor in ''Literature/TheDresdenFiles''. A coalition of supernatural races that was driven into the sea by their rivals several thousand years ago, and so were forced to biologically engineer themselves to survive in their new environment.
* Dagon from ''Literature/TheSecretsOfTheImmortalNicholasFlamel.''
* Mature fin folk in ''Literature/TheSeaOfTrolls.''
* The Fish Footman in ''Literature/AlicesAdventuresInWonderland''.
* A race of marsh dwellers referred to as "Grik-toads" combining lizard and froglike features are encountered on an isolated island in the ''Literature/{{Destroyermen}}'' series.
* The Literature/{{Boojumverse}} has a human subspecies called "gillies", disliked by ordinary humans but valued because they are capable of surviving extreme conditions. They're the Boojumverse equivalent of the Deep Ones from the Franchise/CthulhuMythos, complete with occasional reference to their "cold fishy gods".
* ''Literature/RevelationSpaceSeries'' have engineered sentient species created on Europa by mixing human and fish genes called Denizens.

[[folder:Live-Action TV]]
* ''Series/DoctorWho'':
** The show has famously featured the [[Recap/DoctorWhoS9E3TheSeaDevils Sea Devils]], as well as a more literal kind of Fish People in "[[Recap/DoctorWhoS4E5TheUnderwaterMenace The Underwater Menace]]".
** The new series has the [[Recap/DoctorWhoS30E6TheDoctorsDaughter Hath]], which are definitely more human-like, and the [[Recap/DoctorWhoS31E6TheVampiresOfVenice Saturnynians]], fish-like aliens with insectoid exoskeletons.
** The Expanded Universe has the Krill and the Selachians, as well as one-time ''Magazine/DoctorWhoMagazine'' companion Destrii.
** In "[[Recap/DoctorWhoS34E6TheCaretaker The Caretaker]]", the Twelfth Doctor invites Clara to go on various adventures, including visiting some fish people.
* In ''Series/BuffyTheVampireSlayer'' episode "Go Fish" the Sunnydale High swim team [[LegoGenetics mutates]] into fish dudes due to their coach giving them illegal, Soviet fish-based steroids. Unusually for monsters in a Buffy episode, they all lived HappilyEverAfter in the ocean -- although they did lose their human personalities, so the swim team essentially died.
* The kleptomaniac (or at least both the individuals we've seen) Blowfish race in ''Series/{{Torchwood}}''.
* The Mire Men in ''Series/{{Knightmare}}'''s eighth season.
* The wormhole-researching Pathfinders in the ''Series/{{Farscape}}'' two-part episode "Self-Inflicted Wounds", and Oo-Nii in another two-parter, "What Was Lost".
** Also the toad-like Hynerians, who also happen to be amphibious.
** Another fish-like/toad-like race is the Sheyang. They look like giant anthropomorphic toads and they explode if shot.
* Old Gregg from ''Series/TheMightyBoosh''. Legendary fish. Some say he's half man, half fish. Others say it's more of a 70/30 split. Whatever the percentage, he's one fishy bastard. In keeping with the fishy theme, ''Series/NoelFieldingsLuxuryComedy'' features a character named Daddy Push who has a winkle-shell for a head.
* TV series ''Series/NoHeroics'' had a character who was half fish. Specifically, he had the smell, the taste and was white meat...
* The Abbai in ''Series/BabylonFive''.
* The Antedeans in ''Series/StarTrekTheNextGeneration''.
* ''Series/StargateSG1'''s episode "Fire and Water" brings the [[http://stargate.wikia.com/wiki/Ohne Ohne]] to the table.
* The Aquaphibians from ''Series/{{Stingray 1964}}'' are this trope.
* In the ''Series/VoyageToTheBottomOfTheSea'' episode "The Mermaid", Captain Crane captures, well, [[CaptainObvious a mermaid]]. Unfortunately, her companion turns out to be a Creature from the Black Lagoon-type monster who wreaks havoc aboard the Seaview.
* ''Series/{{Beetleborgs}}'': A MonsterOfTheWeek in the episode ''Something Fishy'' is one of these. Initially believed to be the local legend "Charterville Charlie", a creature described as half-man, half-tuna, it turns out to be Swamp Scumoid, the latest monster from the Beetleborgs comics. (Unlike most monsters in the series, Swamp Scumoid didn't come from the source footage of ''Series/JuukouBFighter''; its suit was later used for the gigantic title character of the movie ''Film/KraaTheSeaMonster''.)
* Uncle Gillman in ''Series/TheMunsters'' is a Film/CreatureFromTheBlackLagoon {{Expy}} up to even having a chest as luggage.

* The "Forevers" from Planet Y in the ''Music/{{Ayreon}}'' saga.
* Music/KateBush's label is called Fish People. Its mascot is a person whose head is a fish.
* UK Hard trance label Tinrib stands out as having a nautical theme, complete with one of these as their mascot.
* [[http://www.youtube.com/watch?v=3tTHn2tHhcI "It's Beginning To Look A Lot Like Fishmen"]], a musical abridgement of Literature/TheShadowOverInnsmouth
* Music/BarnesAndBarnes ' "The Fish People Of Berodenon"
* The lyrics of [[WesternAnimation/{{Metalocalypse}} Dethklok]]'s "Go Into The Water" say that humans will someday make a mass exodus to the ocean and live underwater, where we will devolve into fish people and then build an army with which to conquer the surface and flood it.

[[folder:Myths & Religion]]
* One legend pertaining to the legendary Merovingian Dynasty claims that they were descendants of Fish People. The writers of the ''Literature/TheHolyBloodAndTheHolyGrail'', and ''Literature/TheDaVinciCode'' decided to interpret this as that they were in fact the descendants of Jesus Christ, since early Christians used a stylized fish as their symbol, not to mention that the Greek word for fish, ''icthys'', formed a nice acronym of Jesus's name and titles. There isn't an ounce more evidence to prove this theory than there is to prove actual Fish People's involvement, though. It is based on a rather desperate interpretation. "Merovingian" means people of the sea, and so originally most likely referred to a people who lived on the coast, or settlers who came from overseas. The Merovingians were perfectly historical, and they're called that after an ancestor named Merovech. If Wiki/{{Wikipedia}} may be believed, his name has, despite the similarity to "mere", German ''Meer'', etc, nothing to do with the sea, but means "famed fight".
* There is a report of the 16th century King of UsefulNotes/{{Poland}} being shown a fish-like creature resembling a Bishop, that gestured to be asked for release to a group of Catholic bishops. Upon its release, it made the sign of the cross and disappeared back into the sea.
* The Undine
* Philippine mythology has the ''syokoy'', generally depicted with the typical scales and fins. Sometimes they are said to be able to transform into human shape, but more often they're considered to be a separate race of humanoid merfolk. An example appears in the graphic novel ''The Mythology Class'', by artist Arnold Arre.
* The ''umibozu'' mentioned above probably served as a folkloric antecedent for the ''[[http://pinktentacle.com/2010/01/ningen-humanoid-sea-creatures-of-the-antarctic/ ningen]]'', a sort of gigantic (and absolutely [[UncannyValley terrifying]]) sea creature with vaguely human characteristics. It's probably an urban myth. Hopefully.
* Ginny (or Jenny or Jeannie) Greenteeth, who according to British [[ScareEmStraight cautionary tales]] drowns kids who play too close to the water's edge, is usually described as a green-skinned monster.
* According to Myth/JapaneseMythology, earthquakes are caused by a giant catfish called the ''namazu''. Following the Great Ansei Earthquake that struck Edo (UsfulNotes/{{Tokyo}}) in 1855, a new type of watercolor blockprint, called ''namazu-e'' (catfish pictures) became popular. Examples featuring anthropomorphized catfish can be seen [[http://pinktentacle.com/2011/04/namazu-e-earthquake-catfish-prints/ here]].

* The mermaids of ''Pinball/{{Barracora}}'' are an unorthodox scaleless hybrid of humans and barracudas.

[[folder:Pro Wrestling]]
* [[Wrestling/{{CMLL}} EMLL]] legend Fishman and his sons, El Hijo De Fishman and Black Fish.
* Wrestling/{{TNA}} revealed there were multiple Shark Boys and [[Wrestling/DaffneyUnger Shark Girl]]s .
* [[Wrestling/TakuyaSugi Namazu Man]], a catfish man.

[[folder:Tabletop Games]]
* ''TabletopGame/DungeonsAndDragons'':
** The locathah, consciously designed after the Film/CreatureFromTheBlackLagoon.
** The sahuagin are another example that in many settings were brought into being by Sekolah, the god of sharks.
** In 3E, every 1 in 100 sahuagin would be born looking like their hated enemies, the sea elves. Most of these mutants, called malenti, were [[EatsBabies eaten by their own parents]]. Some of them are raised to be deep cover infiltrators for sahuagin, though.
** The ''Savage Species'' supplement introduced the [[FunnyAnimal anthropomorphic animal]] template, which can be applied to any creature with the Animal type, including mundane fish.
** And then there are the kuo-toa, which are ''subterranean'' fishmen. Mostly inspired by the Deep Ones from Franchise/CthulhuMythos.
* Along with the standard [[TabletopGame/DungeonsAndDragons D&D]], ''TableTopGame/{{Pathfinder}}'' has.
* In ''TabletopGame/{{Pathfinder}}'', there are several varieties of FishPeople, such as ''D&D'''s sahuagin and locathah and others such as the anglerfish-inspired ceratioidi and the shark-like adaros.
** Many of these races are products of the Aboleth's influence on ancient human history. Most obvious are the degenerate survivors of an ancient and abandoned slave race, who are technically named Ulat Kini but known by everyone, including themselves, as Scum.
* The very first edition of ''[[TabletopGame/{{Warhammer}} Warhammer Fantasy Battle]]'' has a race actually called the Fishmen. The 8th Edition book has reintroduced references to them, causing no small amount of EpilepticTrees.
* The Homebrew ''TabletopGame/NewWorldOfDarkness'' game ''TabletopGame/LeviathanTheTempest'' allows the player to play demigod fishmen descendants of beings such as Dagon. It originally began as a joke that White Wolf should [[TabletopGame/VampireTheRequiem complete the]] [[TabletopGame/WerewolfTheForsaken Universal]] [[TabletopGame/PrometheanTheCreated Monsters]] [[{{Mummy}} stable]] by making a "Creature of the Black Lagoon" {{Splat}}, but then it took a turn towards Ancient Mediterranean mythology and ''Literature/TheShadowOverInnsmouth''...
* The Triton parahumans in ''[[TabletopGame/{{GURPS}} GURPS: Bio-Tech]]'' have their gills on their chests in order to function properly. The extensive modifications needed to let them survive underwater required making them inhuman inside and out.
* The Merfolk of ''TabletopGame/MagicTheGathering'' are more fishlike than most, featuring scales all over their bodies, and some have legs instead of fish tails. There are also Homarids, who are lobster-people, and Cephalids, octopus-people.
* ''TabletopGame/FiftyFathoms'' has fish people, crab people, squid people, dolphin people, seal people and (villainous) octopus people.
* The Sea Folk, a playable race in ''TabletopGame/BlueRose'', are technically more like Dolphin People -- they can't actually breathe underwater (but can hold their breath for an hour or more), aren't scaly, and are portrayed as graceful and elegant rather than repulsive. They can also live on land and interbreed with normal humans, although they need to immerse themselves in water daily and usually stick near the coasts.
* ''TabletopGames/RocketAge'''s Titan is inhabited by two intelligent species, one of which a race of literal StarfishAliens, while the other is the H'ykar. Described as a cross between a man, a frog and a fish, the H'ykar live in semi-submerged communities and have only just began to practice agriculture.

* The Barraki and Karzahni in ''Toys/{{Bionicle}}'' are of the mutated former land dwellers kind, save for Ehlek the Eel Barraki, who was aquatic to begin with.
* Lagoona Blue from ''Franchise/MonsterHigh'', who has a pretty strong case of the [[Literature/TheShadowOverInnsmouth Innsmouth Look]] going on- blue skin, protruding eyes, full lips, a nose so flat as to be virtually nonexistent, fins on her arms and legs and serving as her ears, and webbed fingers. There's also her boyfriend, Gillington "Gil" Webber.

[[folder:Video Games]]
* The Neptune's Shell from ''VideoGame/{{Terraria}}'' turns the player into one when they come in contact with water, allowing them to move through it as if it was air.
* The Zora from ''Franchise/TheLegendOfZelda'' games. Though they're [[http://zelda.wikia.com/wiki/Zora much better looking]] and friendlier than most fish people in the post-''[[VideoGame/TheLegendOfZeldaOcarinaOfTime Ocarina of Time]]'' console games, being elegant, finned blue or red humanoids with head-crests resembling trailing fish tails, the 2D games generally portray them as ugly, Black Lagoon-type monster enemies. ''[[VideoGame/TheLegendOfZeldaOracleGames Oracle of Ages]]'' explains this by stating that the two species are different kinds of Zora: the sleek and friendly ones are Sea Zoras, while the ugly enemies are River Zoras. Queen Oren of ''[[VideoGame/TheLegendOfZeldaALinkBetweenWorlds A Link Between Worlds]]'' is a sort of hybrid between the two designs, sporting the color scheme and secondary features of the River Zoras but being friendlier and more humanoid like the Sea Zoras. She herself is likely a well-disposed River Zora, as that is the kind she rules over and resembles most.
* Rikuo Aulbath and the other mermen ([[LastOfHisKind the few that are left]]) from ''VideoGame/{{Darkstalkers}}''.
** Rikou is named after Ricou Browning, the stuntman who played the Film/CreatureFromTheBlackLagoon in underwater sequences, as a ShoutOut.
* ''VideoGame/{{Warcraft}}'' has the murlocs, primitives who resemble piranhas with arms and legs in place of fins and tail. They're found almost everywhere that has coastline and are generally considered pests by the smarter races due to their typically aggressive nature and high rate of reproduction.
** There's also their Pandaria native cousins, the jinyu, who are larger, more humanoid, and much more intelligent, being able to speak the common tongue and integrate themselves into society.
* The Argonians from ''Franchise/TheElderScrolls'' are LizardFolk with some fish-like features.
* Manillos from ''BreathOfFire''.
** The [[VideoGame/CityOfHeroes Arachnos Archvillain]] [[ThreateningShark Captain Mako is "a mutant who evolved into something that can only be described as a shark-human hybrid."]]
* The Gillmen from ''VideoGame/XComTerrorFromTheDeep'', which were inspired by the Film/CreatureFromTheBlackLagoon. These guys make Goombas look like Brock Lesnar in comparison. More dangerous are Lobstermen: Their thick armor makes them impervious to gunfire, forcing you to get in melee range so they can claw you to death.
* Referred to in ''[[VideoGame/MySims MySims Kingdom]]'', when you go to Cowboy Junction. [[DeadpanSnarker Lyndsay]] replies that it's probably inhabited by a race of fish-men. He doesn't grasp the subtle art of sarcasm...
* ''SuikodenTierkreis'' invokes the series traditions of PettingZooPeople and a [[ThemeNaming theme named]] set of five Stars with the Porpos-kin: cuddly-looking dolphin people who live in an '''unusually''-shaped' coastal town.
** Meanwhile, ''SuikodenTactics'' used a far more disturbing take, with fish people being practically mindless, feral monsters created by [[BalefulPolymorph Baleful Polymorphing]].
* Fireball-spewing Fishmen are one of the staple enemies of the ''Franchise/{{Castlevania}}'' series.
* Trident of ''VideoGame/EternalChampions'' is a Fishman -- from {{Atlantis}}, of course.
* Trilarian, the aquatic race from ''VideoGame/MasterOfOrion 2''. It isn't clear when they debut, but they're confirmed to be fish in ''Master Of Orion'' 3.
* ''VideoGame/{{Fallout}}'':
** In ''VideoGame/Fallout3'' the mirelurks are crabs that have become huge and bipedal [[NuclearNasty due to radiation]], but the mirelurk kings are former snapping turtles that look exactly like the Film/CreatureFromTheBlackLagoon.
** Lakelurks from ''VideoGame/FalloutNewVegas'' are reskins of the aforementioned mirelurk kings, and possess the same stereotypically finned, ichthyoid appearance. They also retain the mirelurk kings' powerful attacks and tendency to cluster in areas near water.
** The ''VideoGame/Fallout4'' DLC ''Far Harbor'' has the Anglers, mutated angler fish that hide in bodies of water to bait prey with their glowing lures, which resemble the glowing stems of local mutated plants. Being mutant animals, they're not too bright when compared to others on this page.
* Blue Minions in the ''VideoGame/{{Overlord}}'' series get very close to this at least.
* In ''VideoGame/SonicAdventure2,'' a tiny version of these appears as one of the animals you can give to your Chao.
* ''VideoGame/PerfectWorld'' has the Tideborn and (more correctly) the Lochmur.
* The heroine of ''VideoGame/{{Aquaria}}'' is a fish person.
* The males of one underwater world in ''VideoGame/EndlessFrontier'' are fishmen. The females are mermaids. Incredibly stacked mermaids. Turns out, much to Haken's humiliation, the females ''like'' scales on their men.
* The Vendeeni from ''VideoGame/StarOceanTillTheEndOfTime''.
* ''VideoGame/{{Dominions}} 3'' has Icthyids, Merfolk, Tritons, Amber Clan Tritons, Kappa, and several other species that fit into this. The Icthyids and Amber Clan Tritons are the most notable, the first because they live on shorelines and under the sea, making useful troops for water entry; and the second because they are terrifying beings armored in Amber that can and will massacre armies bigger than them.
** ''Dominions 3'' also has the nations Atlantis, Oceania, and R'leyh, all of which have fish people, though Atlantis and especially R'leyh have plenty of full blown sea monsters as well.
* The Silth Mouse from ''{{Mousehunt}}'', except the man part is replaced with a mouse. It's also ''[[ThatOneBoss very hard to catch]]''.
* ''VideoGame/DungeonsAndDragonsOnline''[='=]s NoobCave is crawling (or would that be swimming?) with sahuagin.
* ''{{Rift}}'' features Deep Ones as common [[MakingASplash Water Plane]]-aligned foes. They look part gill-man, part crustacean.
* ''VideoGame/EarthBound''[='=]s [[SwampsAreEvil Deep Darkness]] has Manly Fish. And occasionally, his big brother.
* ''VideoGame/{{Starbound}}'' has the Hylotl, a species of East Asian-like pacifists. They, however, have an enormous ego and aren't quite fond of other species, ''especialy'' with the [[RobotBuddy Glitch]] and the [[PlantPeople Floran]].
* The Merian race from ''VideoGame/{{Lusternia}}''. They are decidedly non-human in appearance, being scaled, hairless, blue and finned, but are a highly [[BlueSkinnedSpaceBabe attractive]], intelligent and noble race with a proud history of scientific accomplishment. Interbreeding with humans has resulted in a few crossbreeds, some even having hair - but however diluted the Merian genealogy, all "real" Merians can breathe underwater.
* The [[VideoGame/{{X}} X-Universe's]] Boron are squid people.
* The Dagonian race of ''VideoGame/{{Skullgirls}}'' qualifies, though the females of the race (or the one we've seen so far, at least) fall under CuteMonsterGirl. They even have their own city in The Canopy Kingdom known as "Little [[Creator/HPLovecraft Innsmouth]]".
* ''VideoGame/{{Athena}}'' has these as enemies in the UnderTheSea level.
* ''[[VideoGame/LegacyOfKain Soul Reaver]]'' has the rahabim, a specialized breed of vampire that not only overcame the usual vampiric weakness to water, but adapted fully to it. While their progenitor, Rahab, is more of a merman with a humanoid vampire upper torso and a shark-like tail instead of legs, his progeny are classic gill men with flipper-like feet, froggy faces and a pair of dorsal fins.
* The Hierophant in ''VideoGame/HouseOfTheDead 2''.
* ''VideoGame/ResidentEvilRevelations'' takes place on an abandoned cruise ship and has you fight half-fish zombies.
* ''VideoGame/TheLastRemnant'' has the Yama race, which is the largest of the four races in the game.
* The Gill Beasts from ''VideoGame/{{Blood}}'', bipedal pisceoid creatures with a resemblance to the [[Franchise/CthulhuMythos Deep Ones]].
* The Inklings from ''VideoGame/{{Splatoon}}'' are anthropomorphic squids who can switch between human and squid forms at will. Various other aquatic species are represented by [=NPCs=], such as Spyke the sea urchin and Sheldon the horseshoe crab.
* In ''VideoGame/{{Amea}}'', Mish is implied to be one of these. He has blue skin, Valde calls him "fish-lips", and [[spoiler:a fish tank can be found in a room in the house right above the Infested Dungeon.]]
* ''VideoGame/CarriesOrderUp'' is a strange case; it's a WorldOfFunnyAnimals where all the characters are various forms of marine life, despite taking place on dry land.
* Undyne from ''VideoGame/{{Undertale}}''.
* Fish from ''VideoGame/NuclearThrone'', as a result of mutation.
* Alani from ''VideoGame/{{Battleborn}}'' who's a GreenSkinnedSpaceBabe WarriorMonk that uses [[MakingASplash Water manipulating]] {{Nanotechnology}} to [[CombatMedic attack enemies and heal allies]].
* ''VideoGame/DwarfFortress'': Cave fish men, small, amphibious tribal humanoids with the heads of blind cave fish found in watery areas BeneathTheEarth. They’re not very dangerous by themselves, but the poisons they smear on their blow darts and spearheads can be quite nasty, and their ability to swim up your water reservoirs gives them an edge the other underground animal races lack.
* The Draug in ''VideoGame/TheSecretWorld'' are former Vikings who, while fighting in their North American Vinland outposts, got mutated by [[TheCorruption the Filth]], which turned them into creatures based on the ''draugr'' of Myth/NorseMythology. They have been prowling the seas ever since, responsible for many stories of abandoned {{ghost ship}}s whose crews disappeared without a trace. The story involves them attacking [[LovecraftCountry an island off the coast of Maine]], [[ZombieApocalypse zombifying most of the locals]] in order to turn them into more Draug.
* ''VideoGame/Dota2'' has four heroes that are examples of this trope.
** Silithice the Naga Siren is a Slithereen (sort of an eel-mermaid with an anglerfish-like lure) with a SirenSong and illusion-making abilities, who was exiled by her [[HonorBeforeReason honourbound]] people for losing a single piece of treasure in their undersea vaults.
** Slardar is of the same species as Naga Siren, but much uglier. He is also a guardian of undersea treasure, using his lure light to search for intruders, sees faults in their armor, and draw them to their doom.
** Slark is a small, vaguely shark-like fellow who spent most of his life in cutthroat [[TheAlcatraz Dark Reef Prison]] and is now its only escapee. His gameplay reflects his escape artist nature, being able to slip out of many a sticky situation if not dealt with appropriately.
** Tidehunter is a hulking anthropomorphic SeaMonster who worships an EldritchAbomination called Maelrawn the Tentacular. His most notable traits are his burning hatred for [[FourStarBadass Admiral Kunkka]] as well as his ability to summon Maelrawn when needed.
* One enemy in Round 2 of ''VideoGame/MonsterParty'' is a fish with human legs.
* The inhabitants of the Fishing Village in the Downloadable Content of ''VideoGame/{{Bloodborne}}.'' Persecuted and experimented on by Byrgenwerth College, they made [[DealWithTheDevil a deal]] with [[EldritchAbomination mother Kos,]] a godlike seafaring creature, to save themselves. The men of the village have become transformed into hulking, barnacle-encrusted fish monsters, while the women have become human-sized snail creatures who endlessly breed and cultivate the parasites which spread Kos's "blessing." [[spoiler:Kos's "orphan," the creature birthed from her washed-up corpse, mostly resembles an emaciated full-grown human man with [[{{Squick}} bits of embryo and placenta still stuck to it]], but it does have fishlike qualities such as long fins which resemble a cape or wings.]]
* In ''VideoGame/TheWitcher'', there is a boss battle against Dagon, a PhysicalGod straight out of the Franchise/CthulhuMythos.

* Des from ''Webcomic/ScaryGoRound''.
* In a homage to Creator/HPLovecraft's [[Franchise/CthulhuMythos Deep Ones]], ''Webcomic/TheInexplicableAdventuresOfBob'' makes jokes about the neighboring town of Innsmouth, where the police keep getting (supposedly) crank calls about fish people.
* ''Webcomic/{{Shadowgirls}}'' has [[LovecraftLite another take on]] ''Literature/TheShadowOverInnsmouth'' , although some of those Deep Ones were more crab-like. Some of the fish-like "Ancestors" are [[OurMermaidsAreDifferent rather pretty]].
* The titular character from ''Webcomic/{{Selkie}}''. She's a little sensitive about it.
* [[JerkAss Eridan]] and [[GenkiGirl Feferi]] from ''Webcomic/{{Homestuck}}'' are fish[[AllTrollsAreDifferent trolls]]. Eridan even lampshades it at one point to get Feferi to [[PungeonMaster quit using fish puns]].
* The Aquians of ''Webcomic/{{Zoophobia}}''.
* Zwendelaar, Setanta and company from ''Webcomic/{{Zukahnaut}}''.

[[folder:Web Original]]
* They appear in early on in ''WebOriginal/HundredCompanions'', seemingly charging towards the ship the mercenaries are aboard. [[spoiler: Turns out they're not so much charging as [[AlwaysABiggerFish being chased]].]]
* ''WebVideo/TalesFromMyDDCampaign'' features the Kua-Toa, who thanks some major divine blessings have conquered the entire ocean and a good part of the land.
* In ''WebOriginal/{{Mortasheen}}'' there are several of these, created as servants for the [[OurVampiresAreDifferent mostly aquatic vampires]]. You've got your requisite [[http://www.bogleech.com/mortasheen/gilldevil.htm Creature From The Black Lagoon homage]] and [[http://www.bogleech.com/mortasheen/makkoron.htm man-shark]], but the others are [[http://www.bogleech.com/mortasheen/siluro.htm somewhat]] [[http://www.bogleech.com/mortasheen/tetroxic.htm stranger]]

[[folder:Western Animation]]
* The sea monster from the ''WesternAnimation/JonnyQuest'' episode "The Sea Haunt". It is humanoid in shape and walks like a man, makes noises like a mammal (not a fish), and is clearly at least somewhat intelligent.
* Mer-Man and his fellow Aquaticans from ''WesternAnimation/HeManAndTheMastersOfTheUniverse1983''.
* Mako, one of Doc Terror's EvilMinions in ''WesternAnimation/{{Centurions}}''.
* Two ''WesternAnimation/DuckTales'' episode feature Fish People.
** In "Aqua Ducks", Uncle Scrooge and company are imprisoned by the "fish folk" of {{Atlantis}}, who blame them for all the pollution coming from the surface world.
** "The Ducky Horror Picture Show" includes [[AffectionateParody affectionate parodies]] of famous movie monsters, including the Film/CreatureFromTheBlackLagoon.
* Mona Lisa, from the ''WesternAnimation/TeenageMutantNinjaTurtles1987'' episode "Raphael Meets His Match", was originally a human--specifically, a physics major in college. In short order, she was kidnapped by modern day {{pirate}}-cum-[[LegoGenetics genetic engineer]] Captain Filch, forced to help with his evil experiments, and mutated while escaping from his ship. The result was a fish/reptile MixAndMatchCritter who was smart and strong enough to help the Turtles stop Filch--and cute enough to become Raphael's GirlOfTheWeek. Her [[ShowAccuracyToyAccuracy action figure]] adds to the fishiness by giving her gills.
** Ray from the episode "Rebel Without a Fin" is a male example that is more fish-like, being a mutant manta ray, with abilities from other marine animals; in the same episode, April O'Neil is also turned into a mutant fish.
* Neptunia from ''WesternAnimation/DarkwingDuck'' is another mutant Fish Person. She starts out as a WellIntentionedExtremist who wants {{revenge}} against the surface world for polluting her ocean home (yes, just like one of the ''WesternAnimation/DuckTales'' examples above), which caused her to mutate from an ordinary fish. However, she does a HeelFaceTurn and eventually joins Darkwing's SuperHero team the Justice Ducks -- even though, as she protests any time anybody mentions the name, she's ''not'' a duck.
** Stegmut ''used'' to be.
* The cast of ''WesternAnimation/MonsterForce'' included animated versions of several old school Franchise/UniversalHorror monsters, including the Film/CreatureFromTheBlackLagoon.
** This will be common in other MonsterMash cases including Gill in ''WesternAnimation/GravedaleHigh'' who is also presented as the stereotypical surfer and Gill (yes, the same name) in ''[[WesternAnimation/TheComicStrip The Mini-Monsters]]''.
* Gill from ''WesternAnimation/KimPossible'' is also a once-human mutant, transformed into a Fish Person by toxic waste.
* The Triceraquins from the ''WesternAnimation/SamuraiJack'' episode "Jack Under the Sea".
* Sammy Fishboy from ''WesternAnimation/WhatItsLikeBeingAlone''.
* In ''WesternAnimation/{{Ben 10}}'', one of Ben Tennyson's [[ShapeShifting alien forms]], Ripjaws, is a combination of this trope and [[OurMermaidsAreDifferent Our Mermen Are Different]].
* The people of Kumari Kandam in ''WesternAnimation/TheSecretSaturdays''.
* Otto Aquarius from ''WesternAnimation/TheVentureBrothers''
* The Plutarkians in ''WesternAnimation/BikerMiceFromMars''.
* The absolutely pathetic Fish Guy from ''WesternAnimation/TheMask'', who is an {{Expy}} of Garth from ''Film/WaynesWorld''.
* Creator/{{Rankin Bass|Productions}}' ''[[WesternAnimation/TheComicStrip Tiger Sharks]]'' are human heroes who can [[VoluntaryShapeshifting transform]] into fish-like HalfHumanHybrids.
* ''WesternAnimation/{{Sealab 2021}}'' gives us half-shark, half-Eric Estrada Sharko. Then there's Dolphin Boy, who looks perfectly human but speaks dolphin.
* On ''WesternAnimation/{{Futurama}}'' we have the lobster-esque Decapodians (Zoidberg's race), as well as the residents of a submerged 31st Century UsefulNotes/{{Atlanta}}, who evolved into Mermaids as a result of the Coca-Cola factory causing massive amounts of caffeine to end up in the water.
* In ''WesternAnimation/ThePrinceOfAtlantis'' we have the Atlanteans.
* In the ''WesternAnimation/AdventureTime'' episode "[[Recap/AdventureTimeS2E18SusanStrong Susan Strong]]", [[spoiler: after finding what he believed to be the last tribe of true human beings in the Land of Ooo, Finn discovered that they were merely fish people with hats, possibly save for Susan herself.]]
* Darwin, Gumball's brother from ''WesternAnimation/TheAmazingWorldOfGumball'', is a fish that grew arms and legs [[{{Cephalothorax}} but still has a head connected to his body.]] At one point he was cursed to turn into a "reverse mermaid", but nothing happens because that's basically what he already was.
* Most humanoid water-breathing heroes and villains in ''WesternAnimation/YoungJustice'' don't really look like fish, but Kaldur'ahm has prominent gills as well as webbed hands and feet.
* The antagonistic toad-like Wartmongers in ''WesternAnimation/TheSmurfs''.
* Episode ''The Satanic Saturnians'' of ''The Superman/Aquaman Hour of Adventure'' have the eponymous Saturnians as fish people.

* The "aquatic ape" hypothesis posits that humans evolved from these, with at least one of our primate ancestors having been an amphibious creature that later re-adapted to land. The evidence for it is scant, coming down mostly to evolutionary traits that it argues are better explained by the sea than the savanna, with little in the way of fossil evidence for it. Still, it has inspired a number of writers, including the creators of Creator/AnimalPlanet's mermaid {{mockumentar|y}}ies.
