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.
Current Distribution. Piranhas are not currently found in California or elsewhere in the United States. One piranha was captured in a pond in Riverside County, California in 1987; the pond was subsequently drained and no additional piranhas were found.iranhas are aggressive predators that lurk in vegetation and ambush and chase prey. Their diet consists mostly of insects, mollusks, crustaceans, worms, small fish, and some plant matter, but they often feed in large groups to kill larger prey like capybaras. Piranhas have few predators in the wild except man.
