Red-Bellied Piranha

Their triangular, razor sharp teeth interlock neatly, allowing piranhas to bite down with incredible force and shearing ability. The teeth are not usually visible, being covered by thick, fleshy lips. In the wild, a good portion of their diet consists of fins nipped from the tails of larger fish. Males have a much more intense red belly than the females, especially during breeding season.
