简单描述
型态特徵 | 形态测量图
背棘 (总数): 10; 背的软条 (总数): 28-32. Diagnosis: dorsal fin with 9 spines in the 1st part and 1 spine and 28-32 in the second; second anal spine about half the length of the 1st anal fin soft ray; pectoral fins short, about 19-21% SL; gill rakers short, about as long as gill filament at angle between lower and upper part of gill arch; maxilla extending beyond posterior eye border, eyes small, 7.2-8.4 times in HL, but this character is difficult to use for identification because of allometry (Ref. 81656).
Inhabits coastal waters from shoreline to about 150 m depth, over mud and sandy mud bottoms. Most abundant in waters less than 60 m at temperatures above 18°C. Juveniles and sub-adults enter estuaries and rivers. Feeds mainly on small fishes and crustaceans. Peak spawning season from late spring to early autumn in tropical West Africa (Ref. 4780).
栖息于来自海岸线的沿岸水域到大约 150 公尺深, 在泥与沙泥底之上。 在 18个 ° C. 上面的温度最丰富在水域少于 60 公尺 稚鱼与亚成鱼进入河口与河。 主要吃小鱼与甲壳动物。 在热带的非洲西方部的来自春末到秋初的生殖高峰季节.(参考文献 4780)
