Bites usually happen out of the water: Captured piranhas may chomp on fishermen who try to extricate them from hooks and nets. For the most part, free-swimming piranhas in their natural habitat avoid people, though they may target human swimmers when water levels are low and food is scarce. This probably explainsa 2017 incident in which 70 river-ba...
Research suggests traveling in schools is a defensive strategyagainst predators like cormorants, caimans, and river dolphins. In a 2005 study, cormorant models were shown to groups of captive red-bellied piranhas. The fish who swam alone or in small clusters had faster breathing rates—a clear symptom of stress. By gathering in larger numbers, indiv...
Even well-known meat-eating species like the red-bellied and black piranhas can’t resist the occasional fruit, leaf, or fig. Other species eat mainly nuts and seeds. These fish remove the tough outer shells with their teeth before devouring the contents.
The scales and fins of many fish are 34 to 85 percent protein, but what’s more important is the fact that they’ll often grow back. In other words, they're a renewable food source: A piranha can repeatedly pluck scales off the same victim for years without killing it. The wimple piranhahas turned the scale-grazing strategy into an art form. After it...
Native to the upper half of South America, the black piranha measures 8 to 15 inches long. A 2012 study found it can slam its muscular jaws with a bite force of 320 Newtons, three times stronger than an American alligator’s. Relative to its body size, the black piranha’s bite is more powerful than that of any other bony fish.
South American arapaima can grow to be 10 feet long and weigh over 400 pounds. The slow-moving fish have little to fear from the piranhas who share their habitats. Arapaima scales are ultra-hard on the outside, but there’s a layer of flexible, cross-hatched fiberson the inside. When the scales get bent, they don’t crack, and lab experiments suggest...
Piranha teeth measure up to 4 millimeters long. The upper and lower teeth interlock, allowing the piranha to slice through vegetation, meat, bone, and even metal. For that reason, piranhas shed the teeth on one side of their head—both lower and upper jaws—at once. A 2019 study in Evolution and Developmentfound that piranhas grow a new set of teeth ...
During his travels in the Amazon, TR heard tales of the piranha's vicious nature and recounted them in his book Through the Brazilian Wilderness. “They are the most ferocious fish in the world,” Roosevelt wrote. "They will snap a finger off a hand incautiously trailed in the water; they mutilate swimmers ... they will rend and devour alive any woun...
From Orca: The Killer Whale to Tentacles and Barracuda, a veritable school of aquatic horror movies tried to capitalize on Jaws’s success in the late 1970s. Piranha, a cult classic directed by Joe Dante, rode the wave of this trend. Some biologists have accused the flick—and its gory 2010 remake, Piranha 3-D—of contributing to the public’s negative...
Despite their bloodthirsty reputation, piranhas are a popular aquarium species. Unfortunately, some hobbyists dump them into waterways when they tire of them. They've been reportedin 14 states, including Louisiana in 2021. There’s no evidence that red-bellied piranhas are establishing themselves as an invasive species. But if you're wading in a war...
