臀棘 3; 臀鳍软条: 8 - 9. Diagnosis: body moderately stout, rounded in cross-section; head large, interorbital space almost flat; adipose eyelid well developed, extending unto pupil; upper lip thin, not ornamented (Ref. 57400). Upper lip with single comb-like series of setiform/cilliform, recurved (Ref. 57400, 81659), longish (Ref. 57400) unicuspid teeth, just visible to the naked eye as a fine fringe, and no inner rows (Ref. 81659). Lower lip without teeth, or with a single comb-like series of minute ciliiform teeth (not visible to naked eye) (Ref. 81659). 2nd row at base of lower lip in small fish (Ref. 57400). Hind end of upper jaw reaching a vertical line from posterior nostril; maxillary pad not visible below corner of mouth when closed; origin of first dorsal fin nearer to snout tip than to caudal-fin base; pectoral axillary process well developed (31.5-33% of pectoral-fin length)(Ref. 57400). 11-12 scale rows between origins of 1st dorsal and pelvic fins; anterior parts and bases of second dorsal and anal fins (sparsely) scaled; pelvic fins, anal and lower caudal fin lobe greyish to more or less whitish (never yellowish) (Ref. 57400, 81659).
Inhabits coastal waters (Ref. 2683, 7399, 57400), estuaries (Ref. 2683, 7399, 81659), inshore marine waters and lagoons (Ref. 81659). Also in high salinity waters (up to 73‰)(Ref. 57400). Feeds on phytoplankton and detritus (Ref. 28587). Oviparous, eggs are pelagic and non-adhesive (Ref. 205). Maximum FL reporded 260mm (Ref. 57400), maximum SL 260 mm, common length 200 mm SL (Ref. 81659).
栖息于沿岸水域与河口。 (参考文献 2683,7399) 吃浮游植物与碎屑。 (参考文献 28587)
