Description

Hippopotamyrus ansorgii is an African elephantfish (Mormyridae) from fresh water of the Congo basin in Central Africa. The species has a streamlined, silvery-grey body with a blunt head and reaches about 20 cm. Like other mormyrids it has a weak electric organ and electroreceptors with which it orients itself in turbid water, locates prey and communicates with conspecifics. It feeds on insect larvae and small invertebrates on the bottom. Mormyrids are known for their relatively large brains and complex social behaviour based on electric signals. The species is of limited local fishery importance.
