Rivers of the World

The Elephant Nose which is also called Peter’s Elephant Nose Fish, Long Nosed Elephant Fish and Ubangi Mormyrid (after the Ubangi River) is a very unusual looking fish. What looks to be the nose of an elephant is actually an extension of its mouth. This trunk-like extension is used for food foraging, communicating, navigating and self defense.

The elephant nose is nocturnal and somewhat territorial in nature. It produces a weak electrical field from specially adapted muscle tissue which helps the fish locate food, a spawning mate and potential predators.

According to the IUCN Red List of Threatened Species, elephant fish are of least concern. They are widespread through West and Central Africa.
