Description

The elephantfish is an elephantfish (Mormyridae) from the fresh waters of West Africa. The species has a stocky, dark body with a small, blunt head and a short chin projection. Like other elephantfishes it generates a weak electric field with an organ in the tail base to navigate in turbid water and find prey. It lives near the bottom in rivers and searches at night for insect larvae and small invertebrates. The species is harmless to humans.
