Africa: in West Africa from Ouémé River basin to Niger Delta (Ref. 81268), Cross River (Ref. 85170) and Mungo River in Cameroon (Ref. 81632).
非洲: 單一種, 侷限於非洲西方部; Oueme 流域到尼日三角州以及在河 Mungo ,喀麥隆中。
大小 / 重量 / 年龄
成熟度: Lm ?  range ? - ? cm
Max length : 15.0 cm TL 雄鱼/尚未辨别雌雄; (Ref. 81268)
背棘 (总数) : 0; 背的软条 (总数) : 8 - 9; 臀棘: 0; 臀鳍软条: 23 - 27; 脊椎骨: 39 - 41. Diagnosis: Denticeps clupeoides is closely related to the Clupeidae, characterised by the presence of midventral scutes; it is distinguished from all clupeids by the presence of numerous small denticles on the surface of the dermal head bones (odontodes) and a complete lateral line along the entire length of the sides (Ref. 2848, 81268, 81632, 117233). Unlike the majority of African freshwater clupeids, Denticeps clupeoides lacks a supramaxilla (Ref. 2848, 81268).
Body shape (shape guide): fusiform / normal; Cross section: compressed.
侧线完整。 在臀鳍的一个第三或者四分之一后端上面的背鳍起点是非常长的。 腹鳍前的鳞甲: 15-20, postpelvic 鳞甲: 4-6. 黑色的线背面, 从头部到尾部的。 深色的细纹结合尾鳍的鳃盖到基底, 在尾梗扩大。 银色的在侧边,微白色的腹面上有呈绿色的色彩, 黄色-浅灰色的背面。 鳞片基底的颜色较深区域形成一个垂直偏菱形野外采集的设计。
Found in streams with water of low ionic content; it always occurs in shoals that tend to keep to the middle of the stream, where the current is at its strongest (Ref. 81632, 101724). It is a skilled and untiring swimmer, extremely fast and hence not easily caught (Ref. 81632, 101724). Peak spawning period in Cross River occurs from July to August (Ref. 85170).
