->''"Squid, cuttlefish, and other similarly baleful creatures are all members of the cephalopod family, characterized by HUGE EYES, BEAKS, INTELLIGENCE, and AMBITION. ... They're jet powered, did you know that? They're jet-powered animals and their heads are covered in PREHENSILE TENTACLES. They're carnivorous and most are cannibals!''
-->-- '''T-Rex''', ''Webcomic/DinosaurComics''

This trope is about octopodes, squid, cuttlefish, nautiloids, and ammonites.

Something about these animals is just plain alien. Few Earth natives can lay claim to having anything like BizarreAlienBiology, but cephalopods have a strong claim to it -- they have two gill hearts, one systemic heart, and blue blood. They are invertebrates without carapaces, yet unlike worms and their mollusc kin such as snails and clams, they move with purpose and have large, staring eyes with HellishPupils. There are suckers on their tentacle-arms, and a few species like the colossal squid have ''hooks''.

Their mouths are ''beaked'' and positioned strangely, their bodies look weirdly like heads, they expel clouds of ink to distract their predators, they move strangely, and some can leap out of the water like flying fish. Many of them can change colors and even the texture of their skin and they're somehow able to do this while being ''completely color-blind''[[note]]it's actually been recently discovered that they're not color blind: their bizarrely-shaped pupils allow them to pick up color based on the way light hits the different points in their eyes without having specialized color-detecting cells like human eyes do. How freaky is that?[[/note]]. Some species have donut-shaped brains where their esophagus runs through the "donut hole" [[note]]actually, the portion above the esophagus is called the supraesophageal mass, responsible for sensory processing and roughly analogous to the cerebral cortex of vertebrates, and the rest below the esophagus is the subesophageal mass, which are directly connected to their tentacles. Each tentacles also have nerve masses of their own and partly autonomous, what with octopodes having two-thirds of their neural mass in their tentacles. That is why an octopus' tentacles can move on their own even when cut off from the central brain.[[/note]]. And of course, they are bizarrely intelligent - on the same level as a cat or a bird. Unlike those animals, they don't learn from any parent - the parents die soon after the eggs hatch.

In fiction, sometimes they're horrible, mysterious denizens of the deep. Sometimes they're cute and funny. Largely this is a matter of size, but it's also true that generally the east favors the comical cephalopod while the west favors its big, evil cousin. Cephalopods live in every ocean.

See FlyingSeafoodSpecial if they can fly, and {{Cthulhumanoid}} if they're {{Half Human Hybrid}}s.

Expect CombatTentacles, TentacleRope and, in racier fare, [[MarsNeedsWomen Tentacle Rape]]. Bigger ones can apply for GiantSquid status, and from there it's not that big a jump to KrakenAndLeviathan up to EldritchAbomination. Not to be confused with {{Cephalothorax}} -- those also have large heads and limbs spawning off them, but they're humanoid.

While you're here, also remember to introduce yourself to [[Franchise/CthulhuMythos Great Cthulhu]], the appointed [[SeriesMascot spokesperson]] of the Cephalopod Nation. He gets [[DoNotTauntCthulhu very upset]] if people do not properly acknowledge him.

* ''TabletopGame/MagicTheGathering'':
** The Kraken creature types, which includes the [[http://ww2.wizards.com/gatherer/CardDetails.aspx?&id=2525 Polar Kraken]], one of the biggest creatures in the game.
** The Cephalid, a race of squid-folk portrayed as physically weak but sneaky and conniving.
** ''Zendikar'' brings us the first true legendary octopus: Lorthos, the Tidemaker.
* ''TabletopGame/{{Munchkin}}'' has the Level 18 Squidzilla monster (outright called Cephalopodzilla in French).

[[folder:Comic Books]]
* ''Franchise/SpiderMan'':
** Spider-Man's foe ComicBook/DoctorOctopus. Not really squishy, though.
** Spidey has a lesser foe called the Squid who really ''is'' all squiddly diddly.
* [[http://www.comicvine.com/octoboss/4005-54336/ Octoboss,]] a minor ''ComicBook/{{Invincible}}'' villain, is a horrifying anthropomorphic octopus who straddles the line between {{Humanoid Alien}} and {{Starfish Alien}}. His head and hands are all masses of [[{{Super Strength}} super-strong]] {{Combat Tentacles}}. Since ''Invincible'' is in part a [[{{Franchise/SpiderMan}} Spider-Man]] homage, Octoboss is probably based loosely on {{ComicBook/Doctor Octopus}}.
* [[spoiler:Ozymandias destroys New York using a giant squid at the end of]] the ''Comicbook/{{Watchmen}}'' book. [[Film/{{Watchmen}} The movie]], however, [[spoiler:removes the squid in favor of an energy machine that sends highly destructive blasts of energy to not just New York, but cities around the world, and makes it look as if Dr. Manhattan was responsible]].
* ''ComicBook/SonicTheComic'' has Chaos' final form which is squid-like, unlike the draconic form Chaos went for in the games.
* ComicBook/{{Diabolik}} had to fight octopi twice: the first time was when a millionaire, expecting Diabolik's visit, put his jewels in a chest and the chest in a pool containing seawater and a giant guard octopus (Diabolik [[CombatPragmatist planned to drop a large can of cyanide in the pool]], but found himself in a hurry and had to jump in and knife it to death), while the second time he was peacefully swimming when a wild octopus attacked him (Diabolik knifed this one to death too).
* There's also Shuma-Gorath, a recurring enemy of ''ComicBook/DoctorStrange'', who can best be described as a pile of green tentacles with a giant eye in the middle. As the name and appearance might suggest, he's a lovecraftian chaos entity residing outside our dimension, and is constantly trying to find a way in. He is very unpleasant to deal with to say the least.
* Hive, introduced as a leader of Hydra in ''ComicBook/SecretAvengers''. Basically an ancient weird tentacle-y creature that bonded with a hapless Hydra agent, talks like Q-Bert, and can attach squid-things to other people to raise an army. [[spoiler: When Viper is killed, Hive converts her head into a large green octopus to resurrect her.]]
* The Ogdru Jahad from ''ComicBook/{{Hellboy}}'', being a mix of Lovecraft and Babylonian myths, are often protrayed as enormous tentacled masses beyond our universes borders. They're also the BigBad of the entire setting, are responsible for the creation of Hellboy and have intended for him to bring them into our reality to usher in the End of Days.

[[folder:Film -- Animation]]
* ''WesternAnimation/FindingDory'' uses both the "comical" category and the "evil" one. As mentioned above we have Hank from the "comical" category, the "evil" category is taken over by the GiantSquid that Dory, Marlin, and Nemo meet while looking for Dory's family and it attempts to eat Nemo.
* In ''Disney/TheLittleMermaid'', Ursula is part cephalopod.
* Dave, an octopus, is the main villain of ''WesternAnimation/PenguinsOfMadagascar''.

[[folder:Film -- Live-Action]]
* ''Film/DeepRising'' has a rather disturbing example of GiantSquid size, which ''[[CruelAndUnusualDeath drinks]]'' [[CruelAndUnusualDeath its prey alive]].
* The Watcher in the Water from ''Film/LordOfTheRings'' is definitely this. While the books only showed tentacles leaving the creature's physical appearance unclear, the movie actually shows that it is a gigantic squid/Octopus with a humanoid face.
* Creator/RayHarryhausen's ''Film/TheMysteriousIsland'' based on Jules Verne's novel features a giant ammonite that attacks the characters when they're working to float a sunken ship the end of the movie.
* ''Franchise/PiratesOfTheCaribbean'': THE KRAKEN!
** Its master, Davy Jones, could be considered this too. His head is basically an octopus with tentacles for a beard and a back of the octopus for the back of his head.
* The [[spoiler: FetusTerrible super-facehugger thing]] in ''Film/{{Prometheus}}''.
* ''Film/{{Sharktopus}}'' combines this with ThreateningShark.
* ''Franchise/StarWars'':
** The [[http://starwars.wikia.com/wiki/Dianoga dianoga]] from ''Film/ANewHope'', the one in the Death Star trash compactor, happens to be octopus-like. They're also called "garbage squid". And they will [[http://starwars.wikia.com/wiki/File:Dianoga_in_Toilets.jpg invade toilets.]]
** Although whether the creature is actually evil is debatable, the MindRape Saw Gerrera's LivingLieDetector Bor Gullet inflicts on its victims in ''Film/RogueOne'' provides some serious NauseaFuel and NightmareFuel just by watching the process from the outside. The thing would've been terrifying enough already even without that ability, being a 6-foot tall land-dwelling octopus-thing that menacingly creeps towards you with its wet tentacles eagerly reaching for your temples...
** ''{{Film/Solo}}'' gives us Summa-verminoth, a gigantic space octopus living in the gas nebulas of the Akkadese Maelstrom near the Maw, the unstable and mostly unnavigable cluster of black holes located near Kessel. Han Solo defeats it, by luring it into the Black Hole.
* Italian movie ''Tentacoli'' features a giant octopus that was stirred up by an underwater tunneling project, and developed a taste for humans.
* The famously scary giant squid from Disney's version of ''Film/TwentyThousandLeaguesUnderTheSea''.

* ''Franchise/CthulhuMythos'': The octopus-headed star spawn, and their leader, the Dread Lord C'thulhu, Master of R'lyeh. Creator/HPLovecraft had a strange thing about tentacles and invertebrates in general. There's always, always tentacles, to the extent that anything with tentacles will for better or worse be compared to a Lovecraftian horror. It might be because he was both violently allergic to pretty much all seafood and had something of a phobia about them. The reason there's such a strong "slimy creature from the sea" motif in his monsters is because, to Lovecraft, marine creatures were among the most vile and disgustingly ugly animals in the world. Of course, the Old Gods arent actually celaphods or anything else that resembles terrestrial life, its just the closest approximation of their true appearance that our brains can understand.
* ''Literature/TheLordOfTheRings'' has the Watcher in the Water (a huge squid-thing that guards the gates of Moria).
* Creator/MichaelCrichton's ''Literature/{{Sphere}}'' had "Jerry" summon a swarm of impossible squid, and later a giant squid (an homage to the one from ''Twenty Thousand Leagues Under The Sea'') to attack the undersea station.
* The 1957 French novel ''Niourk'' by Stefan Wul features amphibious, hyperintelligent mutant octopuses.
* Creator/JohnWyndham's ''The Kraken Wakes'' is about the invasion of Earth's oceans by a race of alien cephalopods. (Or at least the organic weapons they deploy are somewhat squid-like; it's never revealed what the actual aliens look like..)
* Creator/VictorHugo's novel ''The Workers of the Sea'' depicts at one point a fight between a sailor and a huge octopus.
-->''A greyish form drifts in the water; big as an arm and half a yard long; it's a rag; this form looks like a closed umbrella without a handle. This rag slowly moves towards you. Suddenly it opens, eight spokes swiftly spread around a two-eyed face; these spokes are alive; there is flamboyance in their dance; it's a wheel of sorts; opened up, it is four or five feet in diameter. Frightening blossom. This thing throws itself at you. The hydra harpoons the man.\\
This beast crawls over its prey, covers it, ties it in its long coils. Below it is yellowish, above it is dirt-toned; nothing could adequately express this eerie dusty shade; it seems a beast made of ashes that would live in water. It is spiderlike in its shape and chameleon in its coloration. Angry, it turns purple. Horrifyingly, it is soft.\\
Its knots strangle; its contact paralyzes.\\
It evokes scurvy and gangrene; it's a disease made monstrous flesh.''
* Creator/IanFleming's ''Literature/DrNo'' has a giant octopus at the end of the obstacle course that the eponymous villain puts Literature/JamesBond through.
* ''Literature/TwentyThousandLeaguesUnderTheSea'' has a battle against multiple giant squid.
* Creator/HGWells' short story 'The Sea Raiders' is about some giant squid who migrate to the English coastline and start eating people. They can even walk about on the shore a bit. The evil aliens in ''Literature/TheWarOfTheWorlds'' are also distinctly squid-like.
* The Martians in Creator/HGWells' ''Literature/TheWarOfTheWorlds'' are basically octopoids.
* The Grim in ''Literature/SeptimusHeap'', which lives in the sewer pipes below the Port and which feeds upon animals falling in them. It's the initiation job (the Task) of Keeper Apprentices to cut one tentacle of off them without being eaten.
* Not evil of themselves, but put to a nasty use: The murder weapons in ''[[Literature/ArchieSheridan The Night Season]]'' are blue-ringed octopuses, whose fatal poison has no antivenom.
* In ''Pandemonium'', the sequel to ''Literature/{{Fragment}}'', the massive underground cave complex in the Urals is home to an ecosystem dominated by bizarre subterranean mollusks. The most disturbing is the puppeteer octopus: a web-tentacled creature that clings to the cave ceiling, drops onto its prey, chews through the victim's nerves with drilling tentacle-suckers, and manipulates the dead carcass like a flesh puppet.

* ''Series/DoctorWho'':
** Daleks are pretty much brains with tentacles in personal [[PoweredArmor tanks]].
** In [[Recap/DoctorWhoS7E1SpearheadFromSpace "Spearhead from Space"]] the Nestenes create "a life-form perfectly adapted for survival and conquest on this planet"; it's basically an enormous squid.
** [[Recap/DoctorWhoS16E5ThePowerOfKroll "The Power of Kroll"]] has a squid with sixty tentacles, some of them half a mile long, all because it had eaten a CosmicKeystone.
** The Bane from the ''Series/DoctorWho'' spinoff ''Series/TheSarahJaneAdventures'' are really [[BuffySpeak squiddy things]].
* The sex education video in ''Series/{{Hyperdrive}}'' shows (fortunately not to the audience) the dangers of InterspeciesRomance with such creatures.
-->"This crewmember had intercourse with a Glygonthian octopoid. Let's take a close look at his genitals. Pustules have developed, and on the pustules: warts. Soon, his entire groin explodes, leaving five baby octopoids, each with his face. Remember, Alien Sex is Danger Sex."
* When [[BigBad N Ma]] from ''Series/MahouSentaiMagiranger'' first breaks free from his [[SealedEvilInACan seal]], he resembles a giant demonic cephalopod. In the final arc of the series, he [[OneWingedAngel transforms]] to a {{Cthulhumanoid}}. In ''Series/PowerRangersMysticForce'', this character is adapted into Octomus the Master.

* [[KrakenAndLeviathan The Kraken]] from the northern legends, though in the first incarnations it was more like a TurtleIsland thing.
* The Oodako (great octopus) is the protagonist of a sad Japanese legend where he forces a girl to marry him.
* In the Hawaiian myth of Creation, the sun was imprisoned in the ocean by a gargantuan octopus, who was slain by a god.

[[folder:Tabletop Games]]
* ''TabletopGame/DungeonsAndDragons'' loves this trope.
** The most popular example are the Illithids, also known as Mind Flayers. They are mostly similar to skinny grey humans but with heads that look like an octopus with four tentacles, which they use to get hold of their victims' heads and eat their brains. They are also parasitic creatures that reproduce by implanting their tadpoles into the brains of humanoids, where they slowly feed on the victim's flesh and grow around its skeleton, eventually completely absorbing and replacing the host. Any humanoids that don't get their brains eaten or have embryos implanted in their heads are used as slave labor.
** And a more straight example would be the Krakens, a race of massive intelligent giant squids. That are also often wizards. They too like to enslave humanoids when they have the opportunity.
** D&D also has the Aboleths, sort of giant half-fish/half-cephalopod things, with three eyes and psychic powers. Like Illithids and Kraken, they too enjoy enslaving humanoids.
* The ''TabletopGame/OldWorldOfDarkness'' had a cephalopod race called the Chulorviah, who could parasitize humans and had plans for world domination.

* Kalmah from ''Toys/{{Bionicle}}''. He and the other [[FishPeople Barraki]] also have guns that shoot out [[AbnormalAmmo vampiric squid]]. The EldritchAbomination [=TrenKrom=] may also qualify.

[[folder:Video Games]]
* The [[StarfishAliens Ceph]] from ''VideoGame/{{Crysis}}'' are as evil as these things come, waking up from their million-year hibernation to destroy humanity and take over the planet. They deploy terrible {{Freeze Ray}}s and horrific flesh-melting [[SyntheticPlague bioweapons]] against population centers (such as [[BigApplesauce New York]]) before invading and fucking the place up with their litho-ships.
* Ultros from ''VideoGame/FinalFantasyVI''. He's mostly [[LaughablyEvil comical]], though.
* ''VideoGame/SuperMarioBros''
** In ''VideoGame/SuperMarioRPG'' the first boss of the sunken ship is a GiantSquid that goes by the name, King Calamari. He has 800 Hit Points and his left tentacles have 200 Hit Points while his right tentacles have 260.
** King Kaliente from ''VideoGame/SuperMarioGalaxy'' is also of the evil cephalopod bunch. Though like most Mario enemies he's also pretty comical.
** Brigadier Mollosque-Lanceur III Dauphin of Bubblaine, is a monstrous purple octopus with fancy clothing with a mustache and hair curls that appears as the boss of [[PalmtreePanic Bubblaine]] in ''VideoGame/SuperMarioOdyssey''.
** ''VideoGame/PaperMario'' series:
*** ''Thousand Year Door'' has the first boss battle against a Blooper.
*** ''VideoGame/SuperPaperMario'' features a boss battle against a giant Blooper during Chapter 3-2.
* ''VideoGame/QuestForGloryIV'' has cephalopod imagery all over to represent the Dark One, possibly a reference to Lovecraft or Czernobog of Russian mythology. There are also "hexapods", six-legged monsters that guard the monastery.
* ''Franchise/MassEffect'' brings us [[EldritchAbomination the]] [[SapientShip Reapers]]. An entire race of horrifically powerful squid-shaped starships bent on perpetuating a [[ViciousCycle cycle of extinction]] on the entire galaxy every 50,000 years, as they have for at least the past 37 ''million'' years. [[AndThatsTerrible And that's 740 cycles!]]
** Some theories suggests that they might have been doing this for a '''billion''' years. And that's ''' 20,000''' cycles!
** They're shaped like cuttlefish because [[spoiler: they were created by the Leviathans, who are giant aquatic beings, and they remade themselves in the image of their creators once they TurnedAgainstTheirMasters and started killing everything.]]
* Oodako the giant octopus boss in ''VideoGame/MuramasaTheDemonBlade''.
* As well as the Watcher from the book, ''VideoGame/TheLordOfTheRingsOnline'' has a giant tentacled terror in the sewers of Carn Dum.
* Some of ''VideoGame/EccoTheDolphin'''s more random enemies include [[AnimalsNotToScale giant octopodes called Eight-Arms.]] The {{Prehistoria}} levels have plenty of pointy ammonites, too.
** ''Defender of the Future'' gives us first the giant octopus, and later a GiantSquid which involves a puzzle to defeat it.
* The first boss of ''[[VideoGame/RatchetAndClank Ratchet and Clank 2]]'' is a huge swamp-octopus thing. Its big brother also acts as a hidden boss.
* Squiddicus from ''VideoGame/DonkeyKongCountryReturns'' and ''VideoGame/DonkeyKongCountryTropicalFreeze'' is a gigantic octopus that spends most of his time attacking ships in the background, but in a few levels he'll attack Donkey and Diddy, smashing platforms and swiping with his tentacles. And he's covered with small spikes, making him invulnerable.
* The Martians from ''VideoGame/MetalSlug'' series, resemble squid or octopi.
* Ozumat, the fiend from below, a massive spawn of the Old Gods who seeks to aid the naga and faceless with their campaign in Vashj'ir in ''VideoGame/WorldOfWarcraft''. He's also the bastard who sinks your ship at the start of the zone. Suffice to say, killing him feels good.
* The giant octopus boss of [[UnderTheSea Quaria]] in ''VideoGame/{{Bug}}!'', which stays in the background, [[TentacleRope grabs fish with its tentacles]], and throws them at you. You counter by [[TennisBoss whacking them back at his head]], after which he will come up close and personal, [[CombatTentacles using his tentacles to hurt Bug directly]].
* The ''VideoGame/MegaManX'' series have Launch Octopus and Squid Adler/Bolt Kraken. [[MechaMooks Though they are anything but squishy]]- the former launches homing missiles and can drain X's life, while the latter makes liberal use of ShockAndAwe.
** Sequel franchise ''VideoGame/MegaManZero'' brings us the [[AnIcePerson cryokinetic]] Tech Kraken, who attempts to cause an earthquake by drilling a suicide submarine into the ocean floor.
* The Xarquids from ''VideoGame/XCOMTerrorFromTheDeep''. Essentially, they're Nautiloids fed on a diet of alien steroids and have a sonic beam shoved up they're tentacles. [[ArsonMurderAndJaywalking And they swim backwards]].
* Gohma Lashers from ''VideoGame/AsurasWrath'', designed to look like a combination of Octopuses and Shelled Cephalopods. They take this to an extreme, being an entire mile or more in length from the top of the head to the end of it's tentacle.
* The second ''VideoGame/TheDishwasher'' game has Squidface, a katana-wielding sword master with an octopus for a head.
* ''VideoGame/KirbysEpicYarn'' has Capamari, the boss of Water World. During the first phase of his battle, he appears to be a squid until you unravel the knitted cap he's wearing, revealing him to be an octopus and triggering the second phase.
* Malamar from ''VideoGame/PokemonXAndY''. Malicious-looking Dark/Psychic humanoid squids that are the Pokemon's equivalent of [[{{Cthulhumanoid}} Mind]] [[TabletopGame/DungeonsAndDragons Flayers]]. They can hypnotize others into doing their bidding, and it doesn't help that they are used by trainers for nefarious purposes. Its pre-evolved form Inkay is more timid and less overtly malicious, but it's still a [[DarkIsEvil Dark-type]].
* Some characters in VideoGame/TheSecretWorld believe that the Dreamers are extra-dimensional cephalopods.
* The single-player story mode of ''VideoGame/{{Splatoon}}'' features the octopus-based Octarians, who fought the Inklings in a previous war and have seemingly returned for revenge. [[spoiler:It turns out their habitats were falling apart and running out of power, and they stole the Great Zapfish to try to fix it.]]
* In the first ''VideoGame/KingsBounty'' game the Kraken sinks the ship of the pirate captain who lead you there. Later you have to face the whole beast, but you have to kill the [[CombatTentacles tentacles]].
* ''{{VideoGame/Conan}}'' has a boss battle against a very GiantSquid at one point during the game.
* The Kraken of ''Videogame/{{Evolve}}'' invokes this. Its mouth is a series of fangs set in the midst of some tentacles, it had tentacles growing out of its back and head, and its 'wings' are essentially tentacles on the ends on normal limbs.
* ''VideoGame/TheWitcher'' series:
** The first game has a more clear example with the boss Zeugl, who is basically an {{Expy}} of the Watcher in the Water, except that instead of having a humanoid head, it has fish head. It also has elements of [[Film/StarWars Dianoga]] as it lives in the sewers. Geralt fights it by combating its CombatTentacles that act like they have a mind of their own.
** The [[VideoGame/TheWitcher2AssassinsOfKings second game]] has the Kayran, an enemy that is a combination of this and a GiantEnemyCrab. It has tentacles from a crab-like monster. It is the first real boss of the game and lives in the swamps.
* ''VideoGame/KidIcarusUprising'': The space Kraken. Pit has to shoot down its tentacles while fighting it. Despite living in space, it can shoot water from its mouth.
* ''{{VideoGame/Castlevania}}'' games have enemies called Dark Octopus, a mutated octopuses tormented by black magic. The monsters were introduced in ''Symphony of the Night'' and later reappeared in ''Order of Ecclesia''.
* A giant, red octopus awaits the player at the bottom of the ocean in ''[[VideoGame/WiiPlayMotion Wii Play Motion's]]'' minigame ''Treasure Twirl''. It seems harmless at first, but when you start reeling up with the treasure chests, ''it suddenly appears at the bottom of the screen and comes after you, trying to impede you way up to the surface''. The scary jingle, as well as the suddenness of the agression makes the whole thing very frightening.

When he comes down, he finds there a mysterious giant squid that messes around with the equipment, and apparently shows signs of the intelligence. [[spoiler:It turns out that the squid got injected with the consciousness of his girlfriend who recently died in an air crash, but whose brain was used [[MadScientist by her father]] as a matrix for his AI research.

** The ecological niche primates once occupied is now filled by tree-swinging, quasi-sapient "squibbons". It is strongly suggested that the squibbons will evolve on to form a civilization. From the same habitat as the "squibbons" comes the "megasquid", an elephant-sized octopus that walks on eight pillar-like legs of pure muscle. Both are stated to come from a family called "terasquids", the land-dwelling descendants of cephalopods.
** In the same time period as the Terasquids above comes the ocean-dwelling "rainbow squid", which resembles a current-era giant squid except with far more impressive colour-changing abilities than any current-era cephalopod.
** 100 million years earlier, a variety of marsh-adapted octopus called "swampus" uses its color-changing abilities to hunt among reed beds, and rears its young in puddles trapped by gigantic lotus flowers.
* In part two of the ''Series/StarTrekTheNextGeneration'' episode "Chain of Command," Gul Madred offers a starving Picard a pink [[AlienLunch Taspar egg.]] Picard cracks it open, revealing a squishy, squiddy thing inside ''which is still alive.'' Undaunted, Picard upends the egg and [[{{Squick}} gulps it down.]]
* A seventh-season episode of ''Series/{{House}}'' has the Patient of the Week eating ''sannakji'', live octopus parts, still moving on the plate. Played for humorous {{Squick}}.
* On ''Series/{{Primeval}}'', Helen leaves a live ammonite on Cutter's desk as a sign she's returned from the distant past via one of the Anomalies.
* Several Mecha in ''Franchise/SuperSentai'' and its adaptation ''Franchise/PowerRangers'' take the shape of a cephalopod.
** ''Series/NinpuuSentaiHurricaneger'' and ''Series/PowerRangersNinjaStorm'' feature a MechaExpansionPack that resembles a giant orthocone, which attaches to the right knee of the Rangers' HumongousMecha, enabling a [[ThisIsADrill Drill attack]].
** ''Series/SamuraiSentaiShinkenger'' features the Ika Origami (Octo Zord in ''Series/PowerRangersSamurai''), which is another MechaExpansionPack. For the Mecha of the main team, it forms a BladeBelowTheShoulder, a backpack and a shield. For the Mecha of the SixthRanger, it turns into a chestplate and a spear or staff.
** The final Mecha introduced in ''Series/DobutsuSentaiZyuohger'' is Cube Octopus, yet another MechaExpansionPack which gives the main mecha a backpack that allows it to fly by spinning what used to be its tentacles.

* The Hawaiian god Kanaloa is represented by an octopus. Despite being associated with the underworld, magic, and the deep sea, he was a pretty decent guy. [[HijackedByJesus However]], Christian missionaries [[EveryoneHatesHades associated him with evil]] when they recast the major deities of the ancient Hawaiians into the Holy Trinity and Satan as part of their conversion efforts.
** In some South Pacific mythologies, the octopus is the sole survivor of the previous universe, befitting its almost alien nature.

[[folder:Tabletop Games]]
* The d20 version of ''TabletopGame/GammaWorld'' has Octhofuses -- a sapient race of octopodes, their name resulting from applying simulated linguistic drift to the original animal's name, like most creatures new to the d20 version. Most of them were actually friendly and curious -- although there was a large, primitive, warlike subrace, roughly to them as orcs might be to humans in a fantasy setting -- and they're considered a valid PlayerCharacter option.
* One of the starting morphs in ''TabletopGame/EclipsePhase'' are "Octomorphs", uplifted octopodes. Depending on the background you pick and your "fluff" choices, a character with this morph might be an actual octopus, another animal with an octopus body, a human with an octopus body, or an AI with an octopus body.
* You can also play an [[UpliftedAnimal uplifted]] cephalopod in ''TabletopGame/TranshumanSpace''. Some of them claim to worship Cthulhu, and humans who discuss it with them aren't sure if they're more unnerved by the possibility this is octosap-humour, or the possibility it ''isn't''.
* ''TabletopGame/StarFrontiers'' features a race of land-dwelling, intelligent, telepathic, purple octopuses (technically they have nine tentacles, but still) in the very first intro module. For extra awesomeness they ride DINOSAURS!

* There are three different octopus Toys/BeanieBabies.
* Toys/{{Squishables}} has both an octopus plush as well as a squid one.

[[folder:Video Games]]
* Octoroks from ''Franchise/TheLegendOfZelda''.
* ''VideoGame/{{Minecraft}}'' has squids that spawn in water. They're a neutral mob, though, and quite passive.
* The ''Franchise/{{Pokemon}}'' Octillery, which as the name suggests, is like a cross between an octopus and a cannon. (it evolves from a revolver fish). There's also Omanyte and Omastar, based on the extinct [[http://en.wikipedia.org/wiki/Ammonite ammonite]].
** ''VideoGame/PokemonXAndY'' introduces Inkay and Malamar, a evolutionary line of Dark/Psychic squid.
* The ''VideoGame/{{Parodius}}'' series has Takosuke and other octopuses among the main characters. The subtitle of the original {{UsefulNotes/MSX}} game translates to ''The Octopus Saves the Earth''.
* ''VideoGame/EndlessOcean'' has octopuses and squid who all act benign towards ''you'', but the second game's giant squid can be periodically seen fighting with a sperm whale.
* The protagonist of ''VideoGame/SwimIkachan'' is a squid, but, as a HeroicMime, tends not to be particularly comical.
* ''VideoGame/{{Jazzpunk}}'' has a giant squid statue as a parody of the ManekiNeko.
* Fluik Games' mascot is a squid. In ''VideoGame/OfficeJerk'' and its SpinOff ''Office Zombie'', you can use the squid as a projectile.
* The stars (and playable characters) of ''VideoGame/{{Splatoon}}'' are the Inklings, squids who can change shape into humanoid teens. Their main enemies are the Octarians, a race of octopus-inspired creatures that resemble octopus tentacles.
* In ''Videogame/{{Evolve}}'' many of the animals are said to be descended from cephalopod like creatures. This is most noticeable with the mammoth birds, reptilian ostriches with Cthulhu heads, and cephaladons, which are crocodiles mixed with squid.
* ''VideoGame/AnimalCrossing'' has Octopus villagers. They're notable for being one of three species that aren't mammals or birds (the others being alligators and frogs, one of two that are also fish that can be caught (other being frogs) and the only one that's based on an invertebrate. They're also the rarest villager as there's only 3 of them in the whole series.
* Cuttlefishes appear as preys in ''[[VideoGame/FeedingFrenzy Feeding Frenzy: Shipwreck Showdown]]''. They spray ink when they see they are about to get eaten, leaving a dark cloud that will disorient the player, making the playable fish slower and much harder to control.

* The rare and endangered [[http://zapatopi.net/treeoctopus/ Pacific Northwest Tree Octopus (Octopus paxarbolis)]].
* ''WebOriginal/OrionsArm'': Has an entire planet populated by cephalopods aptly named Cephalotopia. Some of the stranger examples of intelligent species are Bitenic Squids and [=PsySquids=], neither of which are particularly friendly to humans.

* The Kraken in ''The Adventures of Theatre/TheLeagueOfSTEAM'' short, "Tall Tails", is a cephalopod, although since only its arms are seen it is unknown if it is an octopus, squid or something else.

* The first SuperheroEpisode of ''WesternAnimation/JimmyTwoShoes'' had Heloise create a muscle-enhancing squid that gave Jimmy superpowers. This led to Jimmy's superhero alias being Powersquid.

* The [[UsefulNotes/NationalHockeyLeague NHL's]] UsefulNotes/{{Detroit}} Red Wings typically celebrate the NHL playoffs by letting fans throw octopuses on the ice, a tradition that began in the 1950's (the octopus' eight arms signified the 8 wins--two best-of-seven series--needed to win UsefulNotes/TheStanleyCup in those years). The animal has been long associated with the team as a result, with even the team's mascot being one (Al the Octopus).
** In 2010, when the Wings met the San Jose [[ThreateningShark Sharks]] in the playoffs, comparisons to ''Film/MegaSharkVsGiantOctopus'' began to [[http://sports.yahoo.com/nhl/blog/puck_daddy/post/Begun-the-Mega-Shark-vs-Giant-Octopus-jokes-ha?urn=nhl,237150 pop up.]]
* Paul the psychic octopus was a resident of a German aquarium known for having correctly predicted the outcome of every game that Germany played in the 2010 [[UsefulNotes/TheWorldCup World Cup]], plus the final.
* ''Vampyroteuthis infernalis'', the Vampire Squid from Hell.
* In South-East Asian countries (particularly Singapore and to a lesser extent Malaysia), there is a saying "blur like sotong", meaning someone is inattentive or easily confused. The thinking is the association with blinding ink and being confused and distracted. However, as pointed out elsewhere on this page, cephalapods are very intelligent animals capable of complex thinking processes, and the ink confuses their ''enemies'', not them.
* Several cultures worldwide ascribe mystical properties or religious significance to Ammonite fossils; most notably Hinduism, where they are a symbol of Vishnu.
