Description

The western bottlenose mormyrid is an elephantfish (Mormyridae) from southern Africa. The species has an elongate body with a downward-curved, tube-like snout and a long dorsal fin. It prefers quiet stretches of river channels, deep pools and floodplain lagoons with aquatic plants and may form small shoals. With a weak electric organ in the tail it navigates in turbid water and locates prey. With its snout it roots in the bottom for insect larvae and small invertebrates. The species is harmless to humans.
