Malapterurus electricus is a thickset fish with six mouth barbels and a single fin on its back, just anterior to the rounded tail fin. It is brownish or grayish, irregularly spotted with black, and attains a length and weight of about 1.2 metres (3 ft 11 in) and 23 kilograms (51 lb)

M. electricus is capable of generating and controlling the discharge of up to 450 volts of electricity. It uses its power to defend itself and to capture prey.

Distribution

Africa: typical Sudanian distribution; in much of the Nile system (exclusive of Lake Victoria), Lake Turkana, Lake Chad and Senegal basins, throughout the Niger system and smaller southward flowing basins in west Africa, from Bandama through Volta rivers in Ivory Coast and Ghana (Ref. 44050). Absent from Congo basin

Biology
Occurs among rock favors standing water. Active at night, feeding mainly on fish stunned by electric shocks. The electric organ, capable of discharging 300-400 V, is derived from pectoral muscle and surrounds almost the entire body. It is used both for prey capture and defense.
