Description

The elephantfish is an elephantfish (Mormyridae) from the Congo basin in Central Africa. The species has a stocky, dark body with a small, blunt head. 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.
