Description

Mormyrops nigricans is an African elephantfish of the family Mormyridae from fresh water of West and Central Africa. The species has an elongate, dark body with a fairly large mouth for a mormyrid and reaches about 34 cm. Unlike most mormyrids, which eat small invertebrates, the genus Mormyrops is decidedly predatory and hunts other fishes. Like other mormyrids the species has a weak electric organ with which it orients itself in turbid water and communicates with conspecifics; some relatives even hunt in groups. The species is of local fishery importance.
