Description

The Eastern bottlenose is an elephantfish (Mormyridae) from turbid fresh water of southern Africa. The species grows to about 12 cm and has an elongate, dark body with far-set dorsal and anal fins and a small mouth. With a weak electric organ in the tail it generates electric pulses to navigate, find prey and communicate with conspecifics in the dark water. As a nocturnal bottom-dweller it searches for insect larvae and small invertebrates. The fish is harmless to humans.
