Piranhas will eat just about anything. They like the fruit that drops from the trees, but they will also not hesitate to eat anything living or dead, like other fish, each other, fallen baby birds, amphibians, snakes, lizards, or any mammal that ventures into the water, but will usually not attack unless the animal is bleeding, which creates a feeding frenzy. Piranhas have extremely sharp teeth that are designed for cutting. Natives use the jaws of dead, dried Piranhas to sharpen things like blow pipe darts, etc. Once they attack an animal, it has little chance of escaping because there are so many of these small fish and they eat the flesh in such a frenzy that they strip a small animal down to the bone within hours. A large animal make take a day, but when they're done there is little left but bones.
