Jawbone of Pygocentrus nattereri. Piranhas are normally about 14 to 26 cm (5.5 to 10.2 in) long, although some specimens have been reported to be up to 43 cm (17 in) in length. Serrasalmus, Pristobrycon, Pygocentrus, and Pygopristis are most easily recognized by their unique dentition.
Some of their prey includes fish, mollusks, crustaceans, insects, birds, lizards, amphibians, rodents and carrion (carcasses). Piranhas are diurnal (most active during the day). Piranhas generally eat smaller fish. Larger fish and small mammals may be attacked if there is a school of piranhas. Foraging methods vary in the different life stages of Piranhas. During the day, smaller fish typically search for food whilst at dawn, late afternoon and early evening the larger fish search for food.
