Hepsetidae (African pikes)
Etymology: Hepsetus: Greek, epsetas, -e, -on = boiled, but there is the following sentence: "oí epsetoi" = certain fishes, and also could be related to "psetta" = grouper (Ref. 45335); odoe: The specific name is possibly derived from the Greek 'odon' which means tooth (Brown 1954) (Ref. 88135).

Diagnosis: This species is distinguished from all other Hepsetus species by the following unique combination of characters: number of lateral line scales low, 43–51; nostril-lower jaw distance short, 36.6–42.1% of head length; number of gill rakers high, 17–23; number of scales between dorsal fin and lateral line 7.5-9.5; number of scales between adipose fin and lateral line 4.5-6.5; head width broad, 32.8–42.3% of head length; and internasal distance high, 21.9–28.3% of head length (Ref. 88135).
附属的外翼骨。 在 supraoperculum 上的知觉管。 鼻骨接近彼此。 在下颌上的三角形的关于皮肤的摺层与小的而且圆的上面之上。 体高 4.5-5.8 x SL。 头部 3-3.7 x SL。 眼直径 6-8个 x 头长。 骨骼的公式 8-10/51-58/7-9,4. 区域眼睛上方红色-橘色的标志。 在眼后面的放射淡色与深色的条纹。 黑色的脂鳍。 粉红色到浅灰色的鳍。 成鱼在偶鳍上可能有黑色的斑点。
This species seems to prefer upper river courses or small rivers where Hydrocynus species are absent or scarce (Ref. 81278).
出现于大多数的沿海河川，湖与沼泽。 (参考文献 3569) 偏爱安静，深水域, 像大洪泛区的峡道与泻湖。 稚鱼与鱼苗居住于植物生长良好的边缘栖息地。 成鱼吃鱼, 稚鱼吃小型无脊椎动物与鱼。 多次产卵的鱼; 在夏天数个月以来繁殖。 相当生命期短又唯一的 4-5 年.(参考文献 7248) 也用拖网捕获。
