Description

Marcusenius senegalensis is an African elephantfish of the family Mormyridae from rivers of West Africa, including the Senegal and the Niger. The species has an elongate, laterally compressed, dark body and reaches about 32 cm. Like other mormyrids it produces weak electric discharges, with which it orients itself in turbid water, locates prey and communicates with conspecifics. The diet consists of small invertebrates and insect larvae on the bottom. The species is of limited local fishery importance. Owing to its crepuscular and nocturnal habits relatively little is known about its precise behaviour.
