Environment / Climate / Range
Marine; brackish; benthopelagic; depth range 20 - 100 m (Ref. 2683), usually 20 - 100 m (Ref. 54930). Tropical; 15°C - 22°C (Ref. 54930); 35°N - 19°S, 26°W - 14°E (Ref. 54930)
Length at first maturity / Size / Weight / Age
Maturity: Lm 24.1  range ? - ? cm
Max length : 35.0 cm FL male/unsexed; (Ref. 7097); max. published weight: 2.0 kg (Ref. 27584)
Eastern Atlantic: Morocco to Angola. Sometimes ranging south to northern Namibia (Ref. 27121).
Adults are sometimes found near the surface. They form schools (Ref. 2683). Commercial fishing trawlers catch this species at depths up to 650 m (J. Luyben, pers. Comm. 10/02). Adults feed mainly on crustaceans (Ref. 4233). Eggs are pelagic (Ref. 4233).
