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: 38 - 45. Diagnosis: tooth patches broad; 9-12 anal-fin rays; 38-41 vertebrae; 19-20 caudal-fin rays (ii-7-8-ii-iii); stout, cylindrical head; broad, square snout; body finely spotted (Ref. 44050).
顏色類似 M. microstoma ，而且 M. monsembeensis 相當均勻地有小的深色印記佈滿整個的身體與尾鰭; 沒有明顯的深色或灰白的橫帶或條紋。 在有一個方面有別於 M. microstoma 較寬的嘴，較少的脊椎骨 (vs.44-46) 與較少的角鰓骨鰓耙。 (vs.20-24) 有別於 M. monsembeensis 有較少的脊椎骨 (vs.47-48).(參考文獻 34006)

生物學特性     字彙 (例如 epibenthic)

Limnetic electric catfish (Ref. 44050). Voracious piscivore (Ref. 36901, 44050, 78218) feeding on cichlids (Ref. 36901, 44050). Encountered in the littoral zone down to a depth of 50 m; especially common in bays or near the mouths of rivers (Ref. 36901).
