Eastern Atlantic: coastal waters of West Africa from Mauritania to Angola or Namibia (Ref. 4445, 81265, 81629). Sometimes it enters freshwater, like in Cross River and Kouilou-Niari River (Ref. 81629). It is often confused with Elops senegalensis (Ref. 81629).
东大西洋: 塞内加尔到安哥拉。 报告出现到至少 23个 °S 。 (参考文献 3968) 记录来自毛里塔尼亚了。 (参考文献 2844) 时常与 塞内加尔海鲢〔Elops senegalensis〕 互相混淆。

简单描述 型态特徵 | 形态测量图

背棘 (总数): 0; 臀棘 0. Diagnosis: Elops lacerta is characterized by 17-19 gill-rakers on lower limb of first gill arch and small scales, those in lateral line numbering 72 to 83 and ornamented with a small, unbranched, tubule (Ref. 2844, 81265, 81629).

生物学特性     字汇 (例如 epibenthic)

Elops lacerta lives in shallow coastal waters over sandy/muddy bottoms, occasionally entering brackish waters and the lower reaches of rivers; from inshore and some way up tidal rivers to edge of shelf (Ref. 4445, 81265, 81629). The reproduction takes place in the sea (Ref. 81265). It feeds primarily on small fishes, mainly clupeids, crustaceans and molluscs; large specimens also feed on insects (Ref. 81629).

生活于沿岸浅水区具有沙的-泥质底部。 偶然地进入半咸淡水域与河的下游。 捕食鱼与虾。 (参考文献 28587) 在海上产卵。
