生態學
; 淡水 居於水底的; pH range: 7.0 - ? ; dH range: 10 - ?; 河川洄游 (Ref. 51243). 熱帶; 22°C - 24°C (Ref. 12468); 20°S - 31°S
Africa: Lower Zambezi River from the delta upstream to at least Tete, if not Victoria Falls, and the lower Shire River; also Pungwe, Buzi and Mulela Rivers (Ref. 75962). Also upper and central Congo basin (Ref. 3203, 95585), Lake Rukwa basin (Ref. 95585), and east flowing rivers of Tanzania and Natal (Ref. 3203).

背棘 (總數) : 0; 背的軟條 (總數) : 20 - 24; 臀棘: 0; 臀鰭軟條: 26 - 31. Diagnosis: Marcusenius macrolepidotus is best distinguished from M. altisambesi by the number of circumpeduncular scales, which is 12-18 vs. 12-14, and an electric organ discharge lacking an initial head-negativity; from M. devosi by the number of scales in linear series along the lateral line row, which is 52-62 vs. 56-66, shorter caudal peduncle length, and weaker Namp of its electric organ discharge; from M. pongolensis by the number of scales in linear series along the lateral line row, which is 52-62 vs. 70-76, the umber of circumpeduncular scales, which is 12-18 vs. 16-20, a greater body depth, and longer Ndur of its electric organ discharge in females and juveniles; and from M. angolensis by its lower number of anal fin rays, being less than 31 vs. 33, and dorsal fin rays, being less than 24 vs. 26, and a higher number of circumpeduncular scales (Ref. 75962).
延長 (參考文獻 13337) 的下巴有小的凸起。 (參考文獻 4967)
Caught with dipnets in the Kafue floodplain, Zambia. Prefers well-vegetated, muddy bottomed marginal habitats of rivers and floodplains. A shoaling species which moves inshore after dark. Migrates within rivers. Recorded to move up tributaries in shoals during flood season (Ref. 13337). Feeds on invertebrates, especially midge and mayfly larvae and pupae taken from the bottom and off plant stems. Breeds during the rainy season in shallow vegetated localities; females carry up to 6,000 eggs (Ref. 7248). Possesses electroreceptors over the entire head and on the ventral and dorsal regions of the body, but absent from the side and the caudal peduncle where the electric organ is located (Ref. 10011).
在 Kafue 洪泛區，尚比亞中用手抄網捕獲了。 偏愛植物生長良好的, 泥底部河與洪泛區的邊緣棲息地。 黃昏以後向海岸移動的一個淺灘種。 在河裡面迴游。 記錄到在洪水季節期間在淺灘中向上游支流遷移.(參考文獻 13337) 吃無脊椎動物,蚊與孚游類仔魚與蛹取自了底部與外海的植物莖尤其。 在長滿植物的淺水處的雨季期間進行繁殖; 母魚抱卵向上到 6,000個卵。 (參考文獻 7248) 具有電感受體佈滿整個頭與在身體的腹與背部區域上, 但是發電器官所在的體側與尾梗沒有出現.(參考文獻 10011)
