Description

The elephant-snout fish is a large African elephantfish of the family Mormyridae from East Africa, including Lake Victoria and surrounding waters. The species grows to about one metre and has a streamlined, dark body with a long dorsal fin and a downward-curved, snout-like mouth with which it searches the bottom. Like other elephantfishes it generates weak electric fields to navigate in turbid water, find prey and communicate. It is solitary and nocturnal and feeds on insect larvae and other small bottom animals. The elephant-snout fish is of local fishery importance and harmless to humans.
