生態學
; 淡水 大洋性; 河川洄游 (Ref. 51243). 熱帶
Africa: only in Sahelo-Sudanese river basins (Ref. 81279), including the Nile, Chad basin, Niger, Volta, Senegal and Gambia (Ref. 2880, 5331).
非洲: 生存只在 sudano-sahalian 的流域中 - 尼羅河,查德,尼日/Benoue ,佛塔河,塞內加爾與甘比亞。
大小 / 重量 / 年齡
Maturity: Lm ?  range ? - ? cm
Max length : 86.0 cm TL 雄魚/尚未辨別雌雄; (Ref. 3799); 最大體重: 8.3 kg (Ref. 2880)
Diagnosis: eye <60% of interorbital space; massive profile specially on anterior part (Ref. 2880, 81279). Three scale rows between lateral line and scaly process at pelvic-fin bases; rakers of first gill arch poorly developed; snout-dorsal fin length/snout-ventral fins length different from one; adipose fin grey or black (Ref. 81279). Inferior lobe of caudal and anterior end of anal fin red-orange (Ref. 2880).
大的輪廓特別地在前部上。 眼 <60% 的眼間隔。 非常短的鰓耙。 尾鰭下葉與肛門紅色的前端-橘色的。
Hydrocynus species are piscivorous, but may also eat Caridina and insects (Ref. 28714). Affinities: easily distinguished from two other species in West Africa from the number of scale-rows below lateral line, which is 3 instead of 2 (Ref. 81279).
出現於開放水域棲息地。 以魚為食的也但是可能吃 Caridina 與昆蟲.(參考文獻 28714) 分類相關: 容易地在來自鱗片的數字的非洲西部與其他二個種區分了-列在側線下.(3 取代 2)
