Watch as these Piranhas go into a feeding frenzy as they are fed. Not the best place to go for a swim!
Piranhas have one of the strongest bites found in bony fishes. Relative to body mass, the black piranha produces one of the most forceful bites measured in vertebrates. This extremely powerful bite is generated by large jaw muscles that are attached closely to the tip of the jaw, conferring the piranha with a mechanical advantage that favors force production over bite speed. Strong jaws combined with finely serrated teeth make them adept at tearing flesh. Piranhas have a reputation as ferocious predators that hunt their prey in schools.
