Description

Hopkins's stonebasher is an African elephantfish of the family Mormyridae from West-Central Africa, including the Ogooué drainage. The species grows to about 16 cm and has a streamlined, dark body with a blunt snout. Like other elephantfishes it generates weak electric fields with a species-specific discharge pattern, with which it orients itself in turbid water, finds prey and communicates with conspecifics; these electric signals also play a role in mate recognition. As a bottom dweller it feeds on insect larvae and small invertebrates. Owing to a restricted range the species is listed as Vulnerable (VU). It is harmless to humans.
