This species is distinguished by the following characters: body depth less than head length, 2.7-3.3 in SL (for specimens 14-31 cm SL); head length 2.4-2.8 in SL; D XI,15-17; pectoral rays 17-19 (usually 17-18); body scales ctenoid, cycloid scales on thorax and ventrally on abdomen; body with auxiliary scales; anal fin of adults rounded to slightly angular, longest soft ray 2.0-2.6 in HL; gill rakers of first gill arch 8-10 + 14-16; pyloric caeca 11-17; preopercle with 2-7 enlarged serrae at the angle; upper edge of operculum straight or slightly convex; midlateral part of lower jaw with 2 rows of teeth; lateral-line scales 49-53; caudal fin slightly convex in juveniles, truncate or slightly emarginate in adults. Colour of head, body, and fins pale, covered with numerous close-set brown, brownish yellow or greenish yellow spots (becoming smaller and increase in number as growth increases), the largest about size of pupil, those on front of head smaller than those on operculum; pectoral fins pale, with small dark spots on the rays; posterior edge of caudal fin with a distinct white margin (Ref.
39231
,
90102
).
Usually found in seagrass beds or on fine sediment bottoms near rocky reefs, dead coral, or alcyonarians (Ref.
5222
), in shallow continental shelf waters (Ref.
27353
). Juveniles are common at water depths to 80 m (Ref.
6390
). Probably spawn during restricted periods and form aggregations when doing so (Ref.
27352
). Eggs and early larvae are probably pelagic (Ref.
6390
). Feed on fish and benthic invertebrates, primarily prawns and crabs (Ref.
4787
,
27354
). Caught with hook-and-line, traps, and trawls; common in the markets of Hong Kong, Singapore and probably throughout its range (Ref.
39231
).
