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). Widespread and common in the Cunene and Okavango systems (Ref. 7248). Reports from Pool Malebo (Ref. 41585), the middle Congo River (Ref. 4910) and the Lulua (Kasai drainage)(Ref. 42554) possibly refer to M. angolensis.
非洲: 剛果河流域上游,尚比西河, 坦尚尼亞 (Ruaha) 與納塔爾 (Umhlattuzi) 的東流動河. 廣泛分佈而且常見於庫內內河與奧塔萬戈河流域。 (參考文獻 7248)

简单描述 型态特徵 | 形态测量图

背棘 (总数): 0; 背的软条 (总数): 20-24; 臀棘 0; 臀鳍软条: 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).

生物学特性     字汇 (例如 epibenthic)

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 洪泛区,赞比亚中用手抄网捕获了。 偏爱植物生长良好的, 泥底部河与洪泛区的边缘栖息地。 黄昏以后向海岸移动的一个浅滩种。 在河里面回游。 记录到在洪水季节期间在浅滩中向上游支流迁移.(参考文献 13337) 吃无脊椎动物,蚊与孚游类仔鱼与蛹取自了底部与外海的植物茎尤其。 在长满植物的浅水处的雨季期间进行繁殖; 母鱼抱卵向上到 6,000个卵。 (参考文献 7248) 具有电感受体布满整个头与在身体的腹与背部区域上, 但是发电器官所在的体侧与尾梗没有出现.(参考文献 10011)
