Краткое описание
морфология | морфометрия
колючие лучи спинного плавника (общее число): 10; членистые (мягкие) лучи спинного плавника (общее число): 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).
