Các tia vây lưng cứng (tổng cộng) : 9 - 11; Các vây lưng mềm (tổng cộng) : 22 - 24; Tia cứng vây hậu môn: 4; Tia mềm vây hậu môn: 20 - 23. Gill rakers rudimentary. Minute scales present. Highly compressed body (Ref. 4253). Large dark spot, surrounded by a light ring on each side of the body (Ref. 35388).
Found in areas close to the sea bed (Ref. 6390). Generally solitary. Feeds mainly on schooling bony fishes, occasionally on cephalopods and crustaceans (Ref. 27121). Reproduction takes place at the end of winter and at the start of spring in the northeastern Atlantic, earlier in the Mediterranean. Eggs are pelagic, maturity reached at 4 years (Ref. 36731). Sold fresh (Ref. 9563) and frozen (Ref. 9988). Can be steamed, fried, broiled, boiled, microwaved and baked (Ref. 9988). The flesh is excellent but is utilized little in West Africa (Ref. 5377).
No studies of their reproductive development or early life history have been undertaken in Australia (Ref. 6390). Pelagic eggs (Ref. 35388).
