Description

The pirambeba is a deep, silvery piranha of the family Serrasalmidae reaching about 20 cm. The strongly compressed body has an adipose fin (as in many characins), a sharp, saw-toothed belly keel and a lower jaw with a mouth full of sharp, triangular, interlocking teeth. The species comes from the Amazon basin in South America and lives in slow to flowing water of rivers and floodplains. It eats fish and sometimes clips fins and scales off other fish, supplemented with insects and carrion. In the rainy season it spawns among flooded plants. Because of its sharp teeth a caught animal must be handled with care; it is eaten locally.
