Description

The sickle-snouted mormyrid is an elongate African fish of the family Mormyridae (elephantfishes) reaching about 27 cm. The brown-black body has a strikingly curved, sickle-shaped snout with an inferior mouth, with which the fish probes the soft bottom and crevices for prey. Like all elephantfishes it generates weak electric pulses with an organ in the tail; with them it orients in turbid water, recognises conspecifics and hunts - a kind of 'electric language'. The species comes from the Congo basin and surroundings in Central and West Africa and lives in quiet, turbid rivers and creeks. Mainly at night it hunts insect larvae, worms, crustaceans and small fish. Elephantfishes have a proportionally very large brain mass.
