Senegal Mormyrid Mormyrus rume

Mormyrus rume is native to freshwater systems in West Africa. It is sometimes called the Senegal Mormyrid, and also the Dolphin Mormyrid, but several others in its genus share the latter name (eg the Eastern and the Western Bottle-nosed, M. longirostris, lacerda, and also M. tapirus and M. kannume).

Mormyrids are also called elephant-nosed fish, and sometimes trunkfish (although that is also a name for some species of marine boxfish), along with others in different genera in the same family. The Senegal has two subspecies and can grow to 1 metre long.

Mainly nocturnal and living near the substrate, it eats insects and larvae. It navigates surroundings using electro receptors and presumably feels safe and invisible in a transparent pipe. It has weak electric senses for navigation, communication and hunting prey and can give a mild electric shock for defence.

It is common as human food in its native range.
