The Sauvage's stonebreaker (Petrocephalus sauvagii) is a freshwater fish of the family Mormyridae that grows up to 18 cm.
Description
Sauvage's stonebreaker is a small African fish of the family Mormyridae (elephantfishes) reaching about 18 cm. Unlike many elephantfishes this species has no long snout but a blunt, round little head with large eyes and a small, terminal mouth. Like all elephantfishes it generates weak electric pulses with an organ in the tail; with them it orients in turbid water, recognises conspecifics and keeps contact in loose schools - a kind of 'electric language'. The species comes from the Congo basin in Central Africa and lives in quiet, turbid rivers and creeks. Mainly at night it eats insect larvae, small zooplankton and worms. Elephantfishes have a proportionally very large brain mass.
