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).

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). Feed on plankton and detritus (Ref. 28587). Oviparous, eggs are pelagic and non-adhesive (Ref. 205). Shows 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).
