Description

The Sanaga elephantfish is an elephantfish from the Sanaga basin in Cameroon, West Africa. The species grows to about 17 cm and has an elongate body with a small, downward-directed mouth with a chin appendage. Like all elephantfishes it generates a weak electric field with an electric organ in the tail region to navigate in turbid water, find prey and communicate with conspecifics. It is nocturnal and searches the bottom for insect larvae. The fish is harmless to humans and is assessed as Least Concern (LC) by the IUCN.
