There's food in the water! GATHER THE TROOPS!

"I'm more worried about piranhas. Did you see that movie where they send a nuclear submarine to fight the piranhas, and one of them swims right down the periscope and bites the guy in the eye, and he goes, 'Aah! Aah! Aah!', and that old lady told him it would happen!?"
Milhouse, The Simpsons

It's generally agreed upon that sharks can turn most any situation from bad to worse... and then there's piranhas. Piranhas are portrayed as vicious mindless eating machines that can tear through anything and leave nothing but bones. In other words, thinking of nothing except whatever "food" happens to fall in the water.

Piranhas provide an alternative to sharks for the Shark Pool, where the villain will always walk in with a bloody dripping leg of lamb or goat, dip it in the tank for two seconds, and then remove it to show a bare bone.

In Real Life, the viciousness of a piranha school is not nearly as pronounced as media exaggerations would have you believe. When they're not hungry or are asleep, they flee from anything that disturbs them. Their famous schooling behavior is not done to attack prey, but to protect themselves from predators like caimans, giant river otters, and freshwater dolphins. Piranhas are omnivores and mostly carrion-eaters and rarely attack bigger animals, they may eat smaller animals but are in general very cautious when dealing with something that might attack back. Piranhas are also very shy and are as much afraid of humans as any other fish and would swim away if a human (or any other large animal) drops into water near them. Pet piranhas are even known to hide when humans are around, but they do may bite larger animals particularly wounded or dying ones.

Actual deaths from piranha attacks are questionable at best, but they've been known to feed on human corpses post-mortem, and they do tend to be rather bite-y fish which commonly nip at the hands and feet of waders and swimmers (being opportunistic feeders), particularly during conditions in which they have eaten in a while. All supposed piranha "attacks" which have caused deaths are potentially dubious, as the suspected victims could have just as easily drowned before piranhas arrived to eat their bodies, which may also contribute to the myth.

Whether piranhas can reduce a body to bones, yes, it is possible, but scientists believe that it will require among 300 to 500 piranhas in 5 minutes to reduce a human body to bones, and depends on the piranhas to be starving (well fed piranhas would only take a couple of bites). While President Theodore Roosevelt did once observe Amazon piranhas reduce a cow to a skeleton in a few minutes, this occurred under artificial conditions. The locals had blocked off this portion of the tributary with nets, dumped hordes of extra piranhas in there, and starved them for days before throwing the cow in, all in the name of making a spectacle for the visiting president. Dropping the cow into a pit full of starving humans would have had a similar result, as anybody who's seen a zombie movie could tell you.

That said, we do not advocate jumping into hungry piranha-inhabited waters just because we've told you they haven't been known to kill people. They have sharp teeth and you still might lose some fingers or toes (which has been confirmed to happen).

Not to be confused with piranha solution, a very, very dangerous Real Life chemical cocktail that can scrub nearly anything organic off of a surface (which is named after this trope).

  • A commercial for Energizer batteries features the Energizer Bunny in a cage above a tank of pirahnas, the cage being triggered by a Lie Detector that an Energizer scientist was hooked up to. Whether or not the Bunny took a dive depended on the scientist telling the truth about whether or not Energizer outlasted Duracell in digital cameras.

    Anime and Manga 
  • In Dragon Ball, Ninja Murasaki ran across a pond to get away from Goku. Goku was about to swim across when Murasaki warned him there were piranha. Goku didn't know what piranha were, so Murasaki threw a large fish in the water to demonstrate. Understanding, Goku simply jumped over the water.
  • Excel Saga: The title character was dropped at least once into a pit full of piranhas, among other things.

    Comic Books 
  • DC Comics:
    • Aquaman: The comic book explanation for Aquaman's hook hand is that his real hand was eaten by piranhas. Considering this is the guy who commands fish, that had to be retconned so that he doesn't command, he just suggests.
    • New 52: In the Justice League storyline "The Hunt for the Cheetah", Arc Villain the Cheetah is defeated when Wonder Woman throws her off a cliff and into a river with Aquaman and a huge school of piranhas waiting to capture her.
    • Robin Series: During the Zero Hour! tie-in, when Tim suddenly finds himself working alongside a fellow Robin, a time-displaced young Dick Grayson, a jewel thief they're chasing tries to flee by faking having been killed and stripped to the bone by piranhas at the Gotham Aquarium. Tim knows something's not right and, upon reading what kind of piranhas are in the tank, realizes the body definitely isn't their thief since they're not flesh eaters.
  • Punisher: In one story, Frank is being chased through the New York zoo by Mooks. He uses the surrounding wildlife to his advantage, such as holding one mook upside down in the piranha tank (and pulling out his picked-to-the-bone skeleton a short while later).
  • Marsupilami: Rivers in Palombia are infested with piranhas. It's not so much a problem for the marsupilamis themselves, though, since they're fond of eating them.
  • EC Comics: In the Tales From the Crypt story "The Bath", a servant fills a corrupt mine owner's bath with piranhas, with predictable results, as retribution for the owner killing the servant's family.

    Films — Animated 
  • Ice Age 2: The Meltdown: Scrat the squirrel was chased by piranhas at one point during his pursuit of his acorn. However, he manages to fend himself and his beloved nut from the hungry fish, using martial arts.

    Films — Live-Action 
  • Piranha:
  • The Last Dragon: The bad guy has a tank of piranhas. Bruce Leroy shoves his face into the tank for half a second, long enough to scare him and his ditzy moll. Arguably subverted as, rather than a school of small fish, it’s one large but very vicious fish.
  • You Only Live Twice: Blofeld kept a piranha pond in his underground lair — handy for getting rid of failed employees, as Helga Brandt learns the hard way.
  • Speed Racer: One of the bad guys has a tank full of them in his office in a moving truck. It gets a hole shot in it, and he forces one of his Mooks to stick a finger in to keep the tank from draining. The fish all gather around with fascination.
  • Loaded Weapon 1 features an aquarium of red-bellied piranhas in a normal house. William Shatner's villain character views them with bemusement, sticks his head into the tank (with billowing water to simulate an attack), and then lifts his head up with a piranha in his grinning mouth, to the other characters' shock. Later, a Funny Background Event occurs as a police officer has his arm in the tank trying to get something out of it during an investigation, with water billowing and him screaming in pain.
  • In You Don't Mess with the Zohan, Zohan and his arch-nemesis Phantom are seen on the Lebanon beach competing about which one is the tougher, letting themselves get bitten by a piranha to prove their point. It's presence is a two-fold mistake, because a) piranhas are found in South America, and b) they are fresh water fish.
  • Cannibal Holocaust was going to have a scene involving piranhas, but it was cut due to difficulties with the camera and the fish themselves.

    Literature 
  • Bless the Beasts & Children: A character makes a point by telling the story of a friend and his pet piranha, a vaguely charming beastie with a fondness for live goldfish. The friend was unable to keep the piranha, so he put it in a goldfish pond to spend the rest of its days feeding happily. The piranha got greedy, "turned into a goldfish gourmet," and lived entirely on the bellies of the goldfish (apparently the tastiest part.) Then the pond's owners noticed all the belly-less goldfish floating at the top of the pond, moved the survivors to another pond, and dumped in poison. Moral: if you start something (say, eating a goldfish), better finish the job!
  • Downplayed in Able Team #4: Amazon Slaughter. One man is attacked by piranhas while swimming a river, but they only give some nasty bites (at the time, he's more worried because he thinks the pain means he's just been shot).
  • James Bond: In You Only Live Twice, Doctor Shatterhand has piranha pools on his grounds, all the better to dispose of people who have not yet succumbed to the other lethal attractions of his gardens.
  • Daughter of the Lioness: The Royally Screwed Up rulers of the Copper Isles sometimes throw dissidents into a specially-prepared pool of piranha and allow any survivors to go free. Unfortunately, they've figured out not to offer this opportunity when the ratio of dissidents to piranha is too high. Eventually, the fish die from being used to cover up murder by poisoning.
  • In It, the eponymous monster at one point takes the form of a school of piranha... or maybe a character just imagined it. Since the character in question had never seen an actual piranha, they looked more like a child's imagined version of them than the real thing.
  • Doc Savage: In Land of Long Juju, the Island of Long Juju sits in a river surrounded by tiny flesh-eating fish that can strip the flesh of a human in seconds. (The fish is never specifically said to be piranha, thereby averting Misplaced Wildlife, as piranha are not native to Africa).
  • The Bad Guys has Mr. Piranha, known in his rap sheet as "The Butt Biter". He and his over 900 thousand brothers and cousins form a gang in the Amazon River, and are known for eating tourists. Despite this, Mr. Piranha himself ends up switching to the side of good in the end, proving the stereotype wrong.
  • Piranhas Dont Eat Bananas features Brian the piranha, who just wants to eat fruit, and tries to get the others to enjoy it, too. Unfortunately for him, they'd rather stick to eating people, and are honestly just annoyed with his offers.
  • In Fortunately, the Milk, hungry piranhas are one of the many obstacles the protagonist claims to have faced on his trip down to the corner store to get a carton of milk.

    Live-Action TV 
  • Cliffhanger: One episode the Plucky Girl reporter dangling six inches over a stretch of the Amazon river teeming with piranha.
  • In The Most Extreme, it was the misconception of the piranha that gave it second place in the "Monster Myths" category.
  • River Monsters:
    • Jemery doubted this until he dipped a dead duck in a piranha infested river for a few moments. When he pulled it out, the submerged part had been devoured all the way to the internal organs. However, piranha are by nature opportunistic feeders, so of course they'll go after a carcass. Later in the episode, Jeremy jumps into a pool that had been filled with piranha and spent several minutes up to his chest in the water, and exits unharmed. In the River Monsters: Unhooked commentary, he says that shooting that scene was one of the least pleasant things he'd ever done on the show and had wanted to get out of the water much sooner, but the director wouldn't let him.
    • A later season episode once again ends up investigating the possibility of piranhas attacking humans, this time in Bolivia with at least one reported fatality. In this case, however, it was because another fish, the arapaima, had been introduced to the river and the presence of a large, non-native predator had thrown the river's ecology out of balance and left the piranhas much more aggressive than usual due to lack of food.
    • Jeremy's biggest problem with piranha is that; when searching for other fish in South America, he'll always end up catching piranha or have them steal his bait.
    • As noted under Real Life, below, piranhas often learn to associate anything splashing down in the village "garbage dump" as food. At the end of the episode dealing with the disaster of the Sobral Santos, Jeremy comes to the conclusion that the hundreds who died did so because the constant dump of waste from the fish processing plant had caused every predator in the river, from piranha to bull sharks, to associate that spot with an endless supply of food. And that was exactly where the ship sank.
    • The worst piranha problem Jeremy ever encountered wasn't in South America and wasn't with a (normally) carnivorous species. It was in Papua New Guinea and involved the pacu, a larger relative of the piranha that has a diet consisting mostly of plant matter. They'd been introduced to the rivers in New Guinea and, thanks to the absence of their natural predators, had flourished to the point that they devastated the local ecology. With their normal food becoming scarce, they'd reached the point where they'd begun attacking humans, which caused quite a scare among locals as the pacu's flat, squarish teeth left bite wounds that looked disturbingly like they were made by humans. Equally disturbing was their habit of attacking the scrotum of their victims. Several people were confirmed to have bled to death from the attacks, while others were mutilated for life.
  • Penn & Teller Tell A Lie: Referenced and debunked, demonstrated by Teller going for a swim in a tank containing thirty of the little fish — who are less hungry, and more terrified of "big fish" Teller. As Penn Jillette would explain for Vanity Fair, this was done to demonstrate how piranhas artificially inflate tension as they're much more controllable and potentially safe than the general preconception, but ironically, one actually did bite Teller's toe during the stunt.
  • 1000 Ways to Die: One way combines piranha with candiru for a rather gruesome death — especially if you're male.
  • On Boy Meets World when Cory and Topanga are honeymooning at a tropical resort this is used as a background gag heard over the P.A. system: "Attention guests, will the couple who left their dog in the piranha tank please come claim his collar?".
  • Jacques Cousteau: In one special concentrating on the Amazon River, a diver hand-feeds a chicken leg to piranha. As the divers joke afterwards, the piranha did not bite the hand that fed them, but the one that filmed them with the cameraman getting a single bite on his knuckle that didn't require any real medical attention.
  • Survivor: In the Amazon season, a simple fishing excursion resulted in a nice lovely little bite at the men's camp.
  • CSI: In "Table Stakes", the killer disposes of a body by feeding it to piranhas.
  • QI: In the "Killers" episode of the "K" season, Stephen discusses the Pacu fish. From Papua New Guinea and a relative to the piranha, it eats seeds and nuts. It also goes for a different kind of nut, hence its nick name of the "Ball-cutter fish", which goes for the gonads if you are swimming naked near it. There are two recorded deaths by castration from this fish.
  • The Addams Family: One of the family pets is a piranha, the Addams' equivalent of a goldfish.
  • Dragnet: In one of the Sixties episodes, a burglar is discovered to keep his stash of stolen jewelry in a piranha tank to discourage searching by hand. To the show's credit, the piranha will strip the living meat off of bone, but only because the robber intentionally keeps his piranha hungry, feeding them only once a week.
  • Mystery Science Theater 3000 Season 12 episode Killer Fish. As the film is set in South America, quite a bit of riffing was done about what the titular fish could possibly be.

    Newspaper Comics 
  • The Far Side:
    • As always, the standard unit of hungriness in piranhas is stated to be one cow: "They can devour an entire cow in ten minutes". Of course, the strip has a cow note this fact.
    • Another Far Side comic shows the interior of a pet store. The focus of the comic is a cat with wooden pegs for its forelegs, and a piranha swimming in a fishbowl nearby.
      Prehistory of The Far Side: I thought for a long time about what caption to put on this one, then realized it didn't need a caption at all.
    • A third has some (human) explorers wading across a tropical river, while down below a piranha is saying to the rest of his swarm "OK, just nibble at first, but once they yell 'Piranha', let 'em have it!"
    • Another strip has a school of piranha exiting the water in a miniature bus, heading towards a camp where people are sleeping. The caption is "When piranhas dine out".

    Other 
  • A Deviantart piece titled Lucky the Cat features the ghosts of the nine lives of the titular, ironically named feline, all showing how that particular life ended. Death number four shows Lucky with numerous piranha biting onto his paws and tail.

    Tabletop Games 
  • Dungeons & Dragons includes stats for piranhas and giant piranhas in some editions. The original 1st edition Fiend Folio also has "quippers", piranhas adapted to cold-water environments so that players couldn't accuse a DM of having Misplaced Wildlife in a typical pseudo-European fantasy world. 5th edition retconned this, using "quipper" to refer to real piranhas instead.
  • Pathfinder: Onwu azu, meaning "flying death" in the local languages, are fish native to the coasts of the Mwangi Expanse that are essentially identical to saltwater piranhas, but are four feet long and able to fly. They feed on land creatures by preference, attacking in swarms and trying to bleed them to death.

    Theme Parks 
  • Disney Theme Parks: On Disneyland's Jungle Cruise ride, one stretch of the river is infested with animatronic piranha that leap out of the water toward the boat.

    Video Games 
  • Banjo-Kazooie has Bubblegloop Swamp, the water of which is infested with piranhas that take your health away anytime you entered the water. The only way to safely traverse the water was to wear wading boots, or have Mumbo Jumbo turn you into an alligator (because piranhas are afraid of alligators). There's even a piranha-like enemy found in various areas of the game called Chump.
  • The Legend of Zelda:
  • The Punisher features piranha tanks that you can use to threaten enemies into giving you info by holding them just a few inches from the water's surface. Of course, there's nothing stopping you from dunking your victims — Frank sticks the enemy's head in for a few seconds and pulls it out, revealing that most of the guy's face has been eaten off.
  • Spelunky: Piranhas appear in jungle areas. They chase any unfortunate spelunker who jumps into a body of water, but they can kill other enemies as well. And there are also large piranhas!
  • Let's Go Jungle!: One of the types of Mook. Very irritating, because they're hard to hit and attack in swarms, and if even one gets to you before you can kill it, you lose up to about a third of your lifebar!
  • In Spyro: Year of the Dragon, the Midday Gardens world has a level called Spooky Swamp. The water there is full of piranhas! And they will kill you if you so much as land in it, let alone try to swim, unless you get. The hell. Out of there. At least there are warning signs.
  • Darius: Fatty Glutton, a Humongous Mecha piranha. His name may sound laughable, but don't be fooled- he's usually one of the hardest bosses of the games he appears in.
  • Endless Ocean: The second game (Blue World in the US) has them in the Amazon area. You can distract them with food, but they won't react to the pulsar. If you do agitate them, they'll bite you and make your air meter drain faster. It is apparently possible to steer clear if you're careful.
  • In Guild Wars 2 there is an underwater spell that summons piranhas to deal damage over time. There is also a specific underwater level where you have to use bioluminescent plants to get from volcanic vent to volcanic vent because as soon as you leave the safety of a light radius you get eaten by super death killer piranhas and die in a couple of seconds.
  • Strider sees them in the Amazon level: they infest the Amazon River but are actually harmless, simply clinging to Hiryu's sprite if he walks close by. If Hiryu falls into the water, however, the (still harmless) piranhas will rush him en-masse as he slowly sinks into the bottom of the screen.
  • Bubble Trouble: Avertedl; Chombert the Piranha is The Goomba of the game.
  • House of the Dead 2 has the Mofish, which resembles a mutant piranha. These foes are found in water and leap at the players to take bites out of them. They are also seen during the fight with the Hierophant.
  • Super Mario Fusion Revival: Deep in the Amazon River basin (World 2-S4: Rebel River), Marco Rossi found a contingent of Rebel Army forces. However, the only clear way to it is to first traverse a stretch of the Amazon infested with piranha. There is a giant piranha fish nearby with a taste for flesh; contact with it will prove fatal!
  • Leisure Suit Larry 2: Looking for Love (in Several Wrong Places): Failing a specific timing puzzle results in Larry falling into waist-deep water. He notes that there's a weird tingling sensation, then climbs out of the river to find that piranhas have stripped everything below his waist to the bone. Notably, the game ends not because he dies, but because he lost his manhood and can't go on.
  • Animal Crossing: You can catch piranha; the Player Character lampshades this trope when they do ("Which river is this, anyway?"). And after you've donated one to the museum, you can see it bashing itself against the wall of the tank... but the description for it claims, correctly, that piranha are actually quite timid.
  • ADOM: There's a certain location where you need to pass through a pool of piranhas-on-crack that will probably kill you in two or three moves if you try to swim across. Fortunately the game provides you with ways to build a bridge if you know where to look.
  • Sheep Dogn Wolf has piranhas that swallow the player in one gulp.
  • Jaws Unleashed has piranha schools in the second level, set in a flooded Sea World-like amusement park/research complex. The little bastards can drain Jaws' health incredibly fast if he doesn't keep swimming. How the tiny fish can get through the shark's hide and why they're not terrified of the thirty-five-foot great white is a mystery.
  • Kid Pix Studio: One of the "Moopie" stamps is a piranha that leaps out of the water, snapping its teeth.
  • Metal Slug 3 has the Flying Killer enemies, piranha-like fish infesting the jungle water that would strip your character to the bone if they fell in. Like their name suggests, they also can jump out of the water and fly straight at the player!
  • The Amazon Trail: Averted; piranha are only encountered in the fishing minigame, and will never harm your character or your guide even if you capsize the boat.
  • New Dangan Ronpav 3: At one point, Angie and Himiko put on a magic show in which the latter has to escape from an aquarium filled with piranhas. Himiko manages to escape unharmed, but Ryoma's corpse, which was hidden inside the piranha tank above the aquarium, gets reduced to a freaking skeleton.
  • In Final Fantasy VI, Piranhas (or Opinicus Fish in later revisions) are the main foes that Sabin and Cyan fight when they take a dive down Baren Falls to escape The Empire. A purplish piranha called R(h)izopas serves as the boss battle after a few waves of Piranhas are defeated, and it uses powerful elemental attacks.
  • Sonic the Hedgehog:
    • Sonic the Hedgehog has Chopper, a robotic piranha that inhabits Green Hill Zone and jumps out of the water in a vertical fashion. The same game also has Jaws, a robotic piranha that inhabits Labyrinth Zone and swims back and forth in a horizontal fashion.
    • Sonic the Hedgehog 2 has Masher, who acts as Chopper's successor, having a similar apperance and attack pattern and inhabiting Emerald Hill Zone. The same game also has Chop Chop, a robotic piranha that inhabits Aquatic Ruin Zone. He swims underwater and charges towards Sonic and/or Tails if they get close to him.
    • Sonic 3 & Knuckles features Mega Choppers, robot piranhas that inhabit Hydrocity Zone. Rather than damaging Sonic normally, they latch onto him and start draining his rings until you can shake them off (or if playing in Sonic and Tails mode, Tails destroys them).
  • Disney's Kim Possible 3: Team Possible: Many bodies of water have piranha that injure Kim and Ron.
  • In Octogeddon, robotic piranhas are featured among the enemies Octogeddon comes across in the underwater levels. These annoying foes circle at high speed around it before lunging at the octopus.
  • Natica and Sandy: Underwater Rescue: These are the main enemies. You use Natica to kill piranhas with a Blade on a Stick to keep them from taking a bite out of Sandy while she's Chained to a Rock. Since both girls are underwater, taking damage from the piranhas also depletes their Oxygen Meter faster.
  • In ARK: Survival Evolved, giant piranhas based on the real-life Megapiranha (see the "Real Life" folder) are a common hazard in the game's rivers and coastlines. Fortunately, they're pretty easy to kill if you have a spear and are able to strand them in shallow water.
  • The aptly-named Piranha Jungle stage in Tadpole Treble features a school of piranhas that pursue Baton as she makes her way through. They can be staved off if you knock fruit from trees just above the water's surface.

    • In "Daring Don't", the villain Ahuizotl tries to off Daring Do by means of a death trap featuring a pool full of piranhas.
    • In "Non-Compete Clause", a school of biteacudas — fish with bat wings that are visually reminiscent of piranhas, being stout-bodied, river-dwelling carnivorous fish — serves the piranaha's typical narrative role by menacing Rainbow Dash and Applejack when they're dangling over a river infested with them, jumping out of the water and trying to take bites out of the two. As is typical for fictional piranhas, they're depicted as highly aggressive, voraciously carnivorous bundles of sharp teeth and bad attitudes waiting to devour anyone and anything that falls in the water with them.
  • Batman: The Animated Series: In "Mad Love", the Joker came up with a plan to drop Batman into a piranha tank, but gave up on it because he couldn't make the fish smile (thus making the scheme unfunny and thus unworthy of him). Harley figured out how to fix the problem by lowering Batman into the tank upside down so their frowns would look like smiles, but instead of impressing the Joker she enraged him by stealing his victory. And she explained the joke.
  • The Secret Saturdays: Subverted in the pilot episode, when the family is traversing through the amazon river, a piranha bites Komodo's tail. Komodo then proceeds to eat the unlucky fish.

    Real Life 
  • Many villages along rivers with piranha have a designated 'garbage dump' spot in the river, and the piranha will greedily devour anything dumped into the water there, as they've been taught it will be food. It's often fairly safe to swim in the river — unless you try to jump in at the garbage dump.
  • Piranha are also a treat for many predators: botos (Amazon river dolphins), giant river otters, caimans, arowanas, viperfish, and many fishing birds eat them like popcorn. It's funny how the most dreaded predator of the Amazon River is sitting near the bottom of the food chain.
  • What's worse than a swarm of normal piranhas? How about a school of giant piranhas! Meet Megapiranha, a meter long fish that lived 10 million years ago in the interior sea that is now the Amazon River. However, it's only known from a few teeth that seem to have characteristics of both the famous carnivorous ones and the herbivorous pacu (a piranha relative). The scary part is that 40-foot caimans and 12-foot turtles living in the same habitat show that the Megapiranha was just a tiddler in the ancient Amazon.
  • The pacu mentioned above displays similar behavior, but they prefer nuts and seeds that fall into the water rather then hapless prey. Instead of sharp pointed teeth, their teeth are flat grinders, which look disturbingly like human molars and can deliver even worse bites then a piranha bite could.
