背棘 (总数) : 5; 背的软条 (总数) : 8 - 9; 臀棘: 3; 臀鳍软条: 8 - 9. Diagnosis: 8-9 anal soft rays; anal fin and lower lobe of caudal fin whitish or greyish (Ref. 57400). Body with ctenoid scales except for anterior predorsal scales which are cycloid and extend to anterior nostril or slightly beyond (Ref. 81659). Scales numerous (Ref. 57400), not large, 33-41 in a longitudinal series (excluding scales on caudal fin base), 11-14 scale rows between pelvic and first dorsal fin (Ref. 81659). 5-8 mucous canals on scales in front of 1st dorsal fin (only 1, less often 2 or 3, in other Liza species (Ref. 57400). Posterior end of maxilla sigmoid, curved down over premaxilla; serrate, anteroventral edge of lachrymal distinctly concave; pharyngobranchial organ with 1-2 valves, anteroventral valve a moderate size, semi-lunate flap, posterior valve usually vestigial, as a small nodule or, at most, a low papillate fold, and may be absent (Ref. 81659).
Body shape (shape guide): fusiform / normal.
Body shape (shape guide): fusiform / normal.
Adults inhabit shallow coastal waters (Ref. 27121), including estuaries (Ref. 2683, 57400, 81659), lagoons (Ref. 57400), tidal rivers (Ref. 3573), freshwater and supersaline environments (Ref. 81659). They feed on plankton and detritus (Ref. 28587). Oviparous, eggs are pelagic and non-adhesive (Ref. 205). They show a remarkable adaptation to hyperhaline environments (up to 97‰ in the Sine Saloum in Senegal)(Ref. 57400). Specimens from tropical East Atlantic reaching maximum of 280 mm SL and common to 180 mm SL (Ref. 81659).
栖息于沿岸浅水区 (参考文献 27121), 包括河口 (参考文献 2683) 与有潮汐涨落的河川。 (参考文献 3573) 吃浮游生物与碎屑。 (参考文献 28587)
