Description

Mormyrus tapirus is an African elephantfish of the family Mormyridae from rivers of West Africa. The species has an elongate, silvery-grey body with a conspicuously long, downward-curved snout, to which the name refers, and a long dorsal fin; it reaches about 43 cm. With its snout it probes mud and crevices for insect larvae and small invertebrates. Like other mormyrids it has a weak electric organ with which it orients itself in turbid water and communicates with conspecifics. It strongly resembles related Mormyrus species but is distinguished by its longer snout and anal fin. Owing to its size the species is of local fishery importance.
