背棘 (总数) : 0; 背的软条 (总数) : 10; 臀棘: 0; 臀鳍软条: 15. Diagnosis: large fang-like teeth overlapping the jaws when the mouth is closed; gill-rakers long, about equal to the length of gill filaments; body generally > 22% of SL (Ref. 28714). 43-53 scales in lateral line; 2 scale rows between lateral line and scaly process at pelvic-fin bases; eye < 70% of interorbital space (Ref. 2880, 81279). Dorsal-fin origin at about same level as pelvic-fin insertions (Ref. 2880, 80290, 81279). Gill rakers few (5-9/9-12) but rather long (Ref. 2880, 80290, 81279), about equal to the length of gill filaments (Ref. 28714). Tips of adipose and dorsal fins black; forked edge of caudal fin black (Ref. 2880, 80290, 81279). Dark caudal fin coloration may also extend unto median caudal rays, forming crescent-shaped blotch (Ref. 80290, 81279). Dark longitudinal streaks present above the lateral line (Ref. 28714).
身体轮廓比较不细长超过 H. forskalii. 眼 <70% 的眼间隔。长的鳃耙。脂鳍与背鳍黑色的顶端。尾鳍黑色的分叉边缘。

Prefers warm, well-oxygenated water, mainly larger rivers and lakes; all but the largest form roving schools of like-sized fish; aptly described as fierce and voracious; diet increasingly piscivorous, becoming exclusive fish feeders when above 90-100 mm length; feeds on whatever prey is most abundant but Brycinus, Micralestes, Barbus, and Limnothrissa are favored (Ref. 7248, 52193). Piscivorous, but may also eat Caridina and insects (Ref. 28714). Useful food fish in some areas (Ref. 4967).

偏爱温暖的,溶氧量高的水, 主要比较大的河川与湖泊。所有的除了最大的形式之外游动鱼群相似的-大小了鱼; 适当地描述为凶猛而狼吞虎咽的。吃任何的猎物是最丰富的但是 Brycinus ， Micralestes ， Barbus 与 Limnothrissa 被偏爱.(参考文献 7248) 在一些地区的有用食用鱼.(参考文献 4967)

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5312 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01047 (0.00834 - 0.01314), b=3.03 (2.97 - 3.09), in cm total length, based on LWR estimates for this species (Ref. 93245).

营养阶层 (Ref. 69278): 4.4 ±0.0 se; based on diet studies.

Generation time: 3.7 (3.0 - 5.0) years. Estimated as median ln(3)/K based on 14 growth studies.

回复力 (Ref. 120179): 中等的, 族群倍增时间最少 1.4 - 4.4年 (K=0.20-0.30; tmax=11).

Fishing Vulnerability (Ref. 59153): Moderate vulnerability (41 of 100).

价格分类 (Ref. 80766): Unknown.

Nutrients (Ref. 124155): Calcium = 69.1 [24.4, 163.4] mg/100g; Iron = 1.47 [0.76, 3.56] mg/100g; Protein = 19.5 [17.4, 21.7] %; Omega3 = 0.462 [0.179, 1.253] g/100g; Selenium = 75 [30, 165] μg/100g; VitaminA = 30.6 [9.0, 102.8] μg/100g; Zinc = 0.887 [0.602, 1.339] mg/100g (wet weight);
