Description

The cyprinoid stonebasher is an African elephantfish of the family Mormyridae. The species grows to about 33 cm and has a streamlined body with a blunt snout, superficially resembling a carp. It inhabits lakes, lagoons, reservoirs and irrigation canals and is a bottom-feeding insectivore. Like other elephantfishes it generates weak electric fields to orient itself and communicate, using several discharge patterns. It breeds during the flood season, moving onto the inundated floodplains to do so. The cyprinoid stonebasher is eaten locally and is harmless to humans.
