Description

The slendertail stonebasher is a small African elephantfish of the family Mormyridae from West Africa. The species grows to about 11 cm and has a stocky, silvery-grey body with a blunt head lacking the long snout of many relatives, and a conspicuously slender tail stem to which the name refers. Like other elephantfishes it generates weak electric fields to orient itself in turbid water and communicate with conspecifics. As a bottom dweller it feeds on insect larvae and other small invertebrates. Owing to its small size the species is of limited fishery interest and is harmless to humans.
