Description

Knoepffler's elephantfish is an African weakly electric fish of the family Mormyridae from west-central Africa. The species has an elongate, laterally compressed, dark body with the dorsal and anal fins placed far back, characteristic of this family. Like all elephantfishes it generates a weak electric field with an organ in the tail base, which it uses to navigate in turbid, dark water, locate prey and communicate with conspecifics. It inhabits rivers and streams, where at night it searches the bottom for insect larvae and small invertebrates. The species is harmless to humans.
