The Red bellied piranha is a fish from the Amazon River system: it also lives in the coastal rivers of northeastern Brazil, the Paraguay, Parana, and Essequibo Rivers. They have a grey coloration with red bellies and numerous metallic flecks. This fish has very sharp teeth; its usual diet is fish, crustaceans, worms, insects, and the occasional larger animal. These fish usually grow to a length of about 8 - 10 inches in length and have achieved a maximum length of 13 inches.  Whether the Piranha deserves its reputation as a vicious carnivore is a matter of some debate. Theodore Roosevelt established this reputation in his 1914 book Through the Brazilian Wilderness. Many subsequent articles and movies have capitalized on this reputation.
