Africa: a very wide distribution area which includes most of the West African river basins (Ref. 81274), the White Nile, Uebi Shebeli and Juba (Ref. 3203), and the Congo River basin (Ref. 52193). In southern Africa, restricted to the middle and lower Zambezi, Buzi and Pungwe (Ref. 52193). Also known from Lake Malawi, Lake Tanganyika and Lake Albert [former Lake Mobuto] (Ref. 3203, 52193).
非洲: 白色的尼羅河,湖艾伯特湖流域, 內陸的水域從塞內加爾到查德, 在喀麥隆的河, 在幾內亞地區中的小海岸的流域。 廣泛分佈於剛果河流域,馬拉威湖,坦噶尼喀與 Mobuto; 在非洲南部中的佛塔河流域, Whebi Shebeli 與 Juba(如 Mormyrops deliciosus), 它被侷限於尚比西河, Buzi 與 Pungwe 河中下游.(參考文獻 7248)

背棘 (总数) : 0; 背的软条 (总数) : 21 - 33; 臀棘: 0; 臀鳍软条: 38 - 51. Diagnosis: head depressed (Ref. 13337, 52193). Body elongated (Ref. 2915, 13337, 52193), shallow (Ref. 28714), ratio standard length/body depth 4.9-7.5 (Ref. 81274). Mouth large (Ref. 13337, 52193) and terminal (Ref. 13337, 28714, 52193, 81274), with 16-28 teeth in upper, and 14-28 in lower jaw (the number of teeth increases with size) (Ref. 81274). Chin (mental swelling) absent (Ref. 52193). Origin of dorsal fin behind origin of anal fin, nearer caudal fin base than tip of snout (Ref. 4903, 52193). Dorsal fin shorter than anal fin; mouth width subequal to snout length (Ref. 52193). Snout long (Ref. 52193), rounded, its length 1/5-1/4 that of the head (Ref. 4903), almost as broad as head (Ref. 2915, 81274). 21-33 dorsal- and 38-50 anal-fin rays (Ref. 52193, 81274). Head 3.4-5.1 times in standard length; interorbital space relatively broad, ratio head length/interorbital width 2.9-6.8; wide ranges for most of the meristic characters are caused by the existence of geographical clines (Ref. 2915, 81274).
头部扁平的, 口端位与身体延长.(参考文献 13337) SL/ 体高 4.9-7.5. 头部 3.4-5.1 x SL。 吻几乎与头部一样宽。 眼间隔宽的, 头长/ 眼间隔 2.9-6.8. 体节形质特徵的变化在地理的生态群中由于不同。 (参考文献 2915)

生物学特性     字汇 (例如 epibenthic)

Juveniles occur in marginal habitats, adults prefer deep quiet water between boulders and below overhangs, away from strong currents; also occurs beneath Salvinia mats and in river estuaries in Lake Kariba; juveniles prey on invertebrates, mainly shrimps and insect larvae (Ref. 7248, 52193). Adults/larger individuals are piscivorous (Ref. 28714), feeding on small cichlids, minnows and labeos (Ref. Ref. 7248, 52193). May live for 8 years or more; breeds in summer during the rainy season; mature females carry 25000 or more eggs (Ref. 7248, 52193). A fractional spawner (Ref. 10606, 10605). Affinities: M. breviceps.

成鱼偏爱在大圆石以下突出部份之间的深静止的水域, 远离强的水流。 也出现之下 Salvinia 垫与在卡里巴湖的河口中。 稚鱼捕食无脊椎动物, 主要地虾与昆虫幼生。 较大的个体吃小的慈鲷科鱼类,条鱼类与腐食。 可以活到 8个年或更多。 在雨季期间进行繁殖。 (参考文献 7248) 一个少产的鱼种 (参考文献 10606; 10605)。 分类相关: M. breviceps.
