Etymology: Malapterurus: Greek, mala = a lot of + Greek, pteron = fin + Greek, oura = tail (Ref. 45335); electricus: The electric discharging capacity of this electric catfish is described by the specific epithet (Ref. 44050).

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; reports from Congo basin refer to any of the other species in this system (see Ref. 44050 for details).

Biologi     Daftar kata (contoh epibenthic)

Occur among rocks or roots. Favors sluggish or standing water. Active at night, feeding mainly on fish stunned by electric shocks. Described as a nocturnal piscivore that breeds during periods of high water; rarely feeds on molluscs (Ref. 44050). 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. Electric organ discharge (EOD) is intermittent and the amplitude increases with size of the fish (Ref. 10011). Responds immediately to cyclic light changes, exhibiting maximum EOD activity shortly after sunset and lowest activity just after sunrise (Ref. 10798). Its EOD duration decreased from 1.5 to 0.3 ms in response to increased temperature from 15 to 30°C (Ref. 10838). Adults form pairs and breed in excavated cavities or holes (Ref. 7248). Maximum size in Lake Chad reported as 1125mm SL, but most museum specimens much smaller (maximum 400mm SL, Nile River)(Ref. 57130).

It is assumed that the male tends the clutch. Others report that the male takes the eggs into his mouth. It is also unknown how the fry is immune to the electric shocks by the parents (Ref. 1672).
