背棘 (总数) : 10 - 11; 背的软条 (总数) : 14 - 16; 臀棘: 3; 臀鳍软条: 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).

成鱼栖息于岩石的或泥-沙底部; 稚鱼曾经采自岸边泻湖与河口。在西方中非洲水域, 食性鱼 (58%) ，口足目甲壳类 (21%) ，螃蟹 (10%) 与头足类动物 (10%) 包含. 它是一个雌性先熟的雌雄同体。此鱼种的季节性迁移外海的塞内盖尔的海岸被影响藉由季节性的涌升流塞内盖尔外海与毛里塔尼亚。熏制或新鲜使用.(参考文献 9987) 在非洲西方部的市场中深受喜爱的。 (参考文献 5377)

Life cycle and mating behavior 成熟度 | 繁殖 | 产卵场 | 卵 | 孕卵数 | 仔鱼

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。
