Description

The eastern bottlenose mormyrid is an African freshwater fish of the elephantfish family (Mormyridae). The species has an elongate, silvery-grey to brownish body with a blunt, rounded snout and grows to about 22 cm. Like all elephantfishes it generates weak electric fields with which it navigates in turbid water, detects prey and communicates with conspecifics. It lives as a bottom dweller in rivers and streams and hunts mainly insect larvae and other small invertebrates. The electric discharges also play a role in territorial behaviour. The species is harmless to humans.
