背棘 (總數) : 10 - 11; 背的軟條 (總數) : 14 - 16; 臀棘: 3; 臀鰭軟條: 7 - 9. Diagnosis: depth of body less than head length, depth 3.0-3.6 times in SL; head length 2.5-2.9 times in SL; interorbital area convex; preopercle angular, 3.6- large spines at the angle, lowermost directed ventrally; posterior nostril slightly bigger than anterior nostril; maxilla reaches nearly to vertical at rear edge of eye; pelvic fin origin below base of pectoral fins; rounded caudal fin; body scales ctenoid (Ref. 89707).

Adults are found on rocky or mud-sand bottom; juveniles have been taken in coastal lagoons and estuaries (Ref. 5222, 57293). In the west African waters, diet comprise of fishes (58%), stomatopods (21%), crabs (10%), and cephalopods (10%). It is a protogynous hermaphrodite. The seasonal migration of the species off the coast of Senegal is influenced by the seasonal upwelling off Senegal and Mauritania. Utilized fresh and smoked (Ref. 9987). Highly esteemed in the market of West Africa (Ref. 5377).

成魚棲息於岩石的或泥-沙底部; 稚魚曾經採自岸邊潟湖與河口。在西方中非洲水域, 食性魚 (58%) ，口足目甲殼類 (21%) ，螃蟹 (10%) 與頭足類動物 (10%) 包含. 它是一個雌性先熟的雌雄同體。此魚種的季節性遷移外海的塞內加爾的海岸被影響藉由季節性的湧升流塞內加爾外海與茅利塔尼亞。燻製或新鮮使用.(參考文獻 9987) 在非洲西方部的市場中深受喜愛的。 (參考文獻 5377)

Life cycle and mating behavior 成熟度 | 繁殖 | 產卵場 | 卵 | 孕卵數 | 仔魚

Most females change sex at about 9 kg, but smaller males (of 3 to 5 kg) are occasionally found. Total potential fecundity was estimated to range from 789,436 ova in a 44 cm SL fish of 2.2 kg to 12,589,242 ova in a 87 cm SL fish of 12.6 kg. In Tunisia, sex change occurs at 10 to 13 years (6 to 15 kg, 80 to 110 cm TL).東大西洋: 沿著到安哥拉南部的非洲西岸,包括地中海南部。記錄從加納利群島與維德角是未證實的。
