Description

The largeeye mormyrid is an elephantfish (Mormyridae) from West Africa. The species has an elongate body with a downward-curved snout, a long dorsal fin and relatively large eyes, to which the name refers. It inhabits rivers and streams. With a weak electric organ in the tail it navigates in turbid water, locates prey and communicates with conspecifics. With its snout it roots in the bottom for insect larvae and small invertebrates. The species is harmless to humans.
