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).

Diagnosis: tooth patches narrow; pectoral fin placed near body mid-depth; 7-8 branched caudal fin rays (Ref. 44050). 9-11 anal-fin rays, usually 10-11; 38-41 total vertebrae, usually 39-41 (Ref. 57130). Caudal saddle and bar pattern not present in adults (Ref. 57130), poorly developed in all ages (Ref. 44050). Flank and dorsum in adults and young marked with large blotches (some up to 4-5 times eye diameter); caudal fin of adults generally same color as flank ground color or slightly darker, larger specimens usually with spots or blotches in caudal fin (Ref. 44050, 57130).

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).

在岩石或根之中生存; 喜欢滞流或静止的水。活跃的在晚上, 主要捕食被电击打昏的鱼。发电器, 能够排出 300-400 V, 从胸的肌肉被衍生而且几乎包围整个的身体。它是使用过的由于猎物抓取与防卫。发电器放电 (EOD) 是间歇的与那随着鱼的大小增加电流.(参考文献 10011) 紧邻反应就在日出之后在日落与最低的活动之后不久被展现最大的 EOD 活动的循环的光改变。 (参考文献 10798) 它的 EOD 持续时间反应来自 15 到 30 °C 的增加的温度从 1.5 到 0.3 ms 减少.(参考文献 10838) 在挖的洞或洞中成对而且繁殖。 (参考文献 7248)

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).非洲: 在尼日系统各处，出现于许多尼罗河系统 (专门的维多利亚湖) ，特坎那湖，查德湖与塞内加尔流域中, 与在非洲西方部 (河 Bandama 经过佛塔河) 的比较小的在南方的流动流域.(参考文献 44050)
