Description

Weeks's elephantfish is an African weakly electric fish of the family Mormyridae from the Congo basin. The species has an elongate, dark body with the dorsal and anal fins set 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 water, locate prey and communicate with conspecifics; subtle differences in the electric pulses help species recognise one another. It searches the bottom for insect larvae and small invertebrates. The species is harmless to humans.
