Etymology: Malapterurus:Greek, mala = a lot of + Greek, pteron = fin + Greek, oura = tail (Ref. 45335). More on author: Roberts.
Environment: milieu / climate zone / 深度上下限 / distribution range 生态学
臀棘: 0; 臀鳍软条: 9 - 12; 脊椎骨: 44 - 49. Diagnosis: large species (Ref. 34006, 78218). Tooth patches broad; obliquely angled pectoral fins positioned low on body (Ref. 44050). 17-49 (Ref. 34006) or 44-45 (Ref. 44050) vertebrae. 9-12 anal-fin rays; 19 caudal-fin rays (ii-7-8-ii); eye typically oval (along horizontal axis); caudal saddle and bar pattern poorly developed, even in juveniles; body with relatively small spots and flecks; pectoral and pelvic fin rays unpigmented (Ref. 44050). Broader mouth than M. microstoma, and fewer gill rakers and more vertebrae than either M. microstoma and M. tanganyikaensis; small dark marks rather uniformly distributed over the entire body and caudal fin, with no distinct dark or pale bars or bands, as M. microstoma and M. tanganyikaensis (Ref. 34006).
超过 M. microstoma, 与少的鳃耙较宽的嘴与更多的脊椎骨超过任一 M. microstoma 与 M. tanganyikaensis. 小的深色印记相当均匀地布满了整个的身体与尾鳍,没有明显的深色或灰白的横带或条纹, 如 M. microstoma 与 M. tanganyikaensis 。 (参考文献 34006)
Female reaches up to 42.0 SL; carnivorous, feeding on fishes, crabs, and other aquatic creatures (Ref. 44050).
