Description

Wilverth's stonebasher is an African elephantfish of the family Mormyridae from the Congo basin in Central Africa. The species grows to about 26 cm and has a streamlined, dark body with a blunt snout. Like other elephantfishes it generates weak electric fields to orient itself in turbid water, find prey and communicate with conspecifics; each species has its own discharge pattern. As a bottom dweller it feeds on insect larvae and other small invertebrates. Elephantfishes are known for their relatively large brains. The species is eaten locally and is harmless to humans.
