簡短描述
檢索表 | 型態特徵 | 形態測量圖
臀棘: 0; 臀鰭軟條: 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).
超過 M. microstoma, 與少的鰓耙較寬的嘴與更多的脊椎骨超過任一 M. microstoma 與 M. tanganyikaensis. 小的深色印記相當均勻地佈滿了整個的身體與尾鰭,沒有明顯的深色或灰白的橫帶或條紋, 如 M. microstoma 與 M. tanganyikaensis 。 (參考文獻 34006)
Female reaches up to 42.0 SL; carnivorous, feeding on fishes, crabs, and other aquatic creatures (Ref. 44050).
