This species is distinguished by the following characters: body moderately deep, its depth 2.5-2.8 times in standard length; head length 0.9-1 times in body depth, 2.6-3 times in SL, dorsal profile near eye nearly straight; snout moderately short, its length about 1.9-2.4 times in HL, measured without the lip the snout is 0.8-1 times in cheek height, its dorsal profile nearly straight, snout angle relative to upper jaw between 60° and 70°; interorbital space convex; posterior nostril an oblong longitudinal opening, closer to orbit than anterior nostril; eye situated close to or far removed from dorsal profile, its length 3.3-4.8 times in HL; cheek not high, its height 2.4-3.1 times in HL; lateral teeth in jaws rounded often with conical tips, or molars often with tubercles; outer surface of maxilla with a longitudinal ridge; D X,9 with the 4th dorsal-fin spine usually the longest, its length 2.4-3.4 times in body depth; A III,8 soft rays, the first soft ray usually the longest, its length almost equal to or shorter than length of base of soft-rayed portion of anal fin and 1-1.2 times in length of entire anal-fin base; pectoral-fin rays 13; pelvic-fin membranes between rays closest to body without dense melanophores; cheek without scales; 46-47 lateral-line scales usually; 5 ½ scale rows between lateral line and base of middle dorsal-fin spines; 15- 16 scale rows in transverse series between origin of anal fin and lateral line; usually 15 rows in lower series of scales around caudal peduncle; 4-9 scales in supratemporal patch; inner surface of pectoral-fin base densely covered with scales, with a few scales, or naked; posterior angle of operculum fully scaly. Colour of body greenish or grey, shading to white below, centers of scales on upper sides often white; posterior margin of opercle and sometimes base of pectoral fins red; pectoral fins white, yellow, or pinkish; pelvic and anal fins white to orange; dorsal fin white and orange mottled with a reddish margin; caudal fin mottled orange or reddish (Ref. 114226).

Biologie     Glossaire (ex. epibenthic)

Inhabits sandy bottoms in coastal areas, deep lagoons and near coral reefs (Ref. 30573). Juveniles and small adults commonly in loose aggregations over seagrass beds, mangrove swamps and shallow sandy areas while adults are generally solitary in deeper waters. Feeds primarily on crustaceans and mollusks but echinoderms, polychaetes and fishes are also consumed in considerable quantities (Ref. 2295). A protogynous hermaphrodite (Ref. 55367). Caught primarily by handline, traps, trawls, beach seines, and gill nets. Marketed mostly fresh (Ref. 68703).
