Description

Hyperopisus bebe is an African elephantfish (Mormyridae) from fresh water of the Sahel region and Northeast Africa, including the Nile, the Niger and the Senegal. The species has a streamlined, silvery-grey body with a downward-pointing snout and reaches about 51 cm. It inhabits both still and flowing waters and breeds in the flood season. Like other mormyrids it has electroreceptors over almost the entire body and a weak electric organ with which it orients itself in turbid water. It feeds mainly on mollusks, which it picks from the bottom. Owing to its size the species is important for fisheries.
