生態學
海洋; 淡水; 半鹹淡水; 深度上下限 1 - 50 m (Ref. 26999). 熱帶; 21°N - 29°S, 20°W - 15°E
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).
東大西洋: 塞內加爾到安哥拉。 報告出現到至少 23個 °S 。 (參考文獻 3968) 時常與 塞內加爾海鰱〔Elops senegalensis〕 互相混淆。

Maturity: Lm ?  range ? - ? cm
Max length : 100.0 cm TL 雄魚/尚未辨別雌雄; (Ref. 5377); common length : 60.0 cm TL 雄魚/尚未辨別雌雄; (Ref. 2683)
背棘 (總數): 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).
側線鱗片以非分枝的小管裝飾了。 灰色背面, 銀色的平滑側邊; 鰭上色了黃色。
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).
生活於沿岸淺水區具有沙的-泥質底部。 偶然地進入半鹹淡水域與河的下游。 捕食魚與蝦。 (參考文獻 28587) 在海上產卵。
