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).

背面の脊椎 (合計) : 0; 肛門の骨: 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).
Body shape (shape guide): elongated; Cross section: oval.
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).
