What Do Piranhas Eat?

Piranha are carnivores that eat live prey and can also feed on insects, plants and even their own kind. These voraciously hungry fish tend to have a lurk-and-ambush style of attack that occurs en masse, with large groups of piranha feeding at once.

As carnivores, piranhas have a wide-ranging, somewhat opportunistic diet. They will eat whatever meat crosses their path, and because they hunt in groups, they can take down large animals, including cows. These hungry fish, which have rows of incredibly sharp teeth and very strong jaws that allow them to take big bites, will eat everything from humans to snails and other fish.
