Maturity: Lm ? range ? - ? cm
Max length : 86.0 cm TL 雄鱼/尚未辨别雌雄; (Ref. 3799); 最大体重: 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).
大的轮廓特别地在前部上。 眼 <60% 的眼间隔。 非常短的鳃耙。 尾鳍下叶与肛门红色的前端-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).
出现于开放水域栖息地。 以鱼为食的也但是可能吃 Caridina 与昆虫.(参考文献 28714) 分类相关: 容易地在来自鳞片的数字的非洲西部与其他二个种区分了-列在侧线下.(3 取代 2)

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5312 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01122 (0.00514 - 0.02450), b=3.04 (2.87 - 3.21), in cm total length, based on all LWR estimates for this body shape (Ref.
93245).
营养阶层 (Ref.
69278): 3.4 ±0.50 se; based on food items.
回复力 (Ref.
120179): 中等的, 族群倍增时间最少 1.4 - 4.4年 (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
