Short description Identification keys | Morphology | Morphometrics
Dorsal spines (total): 10; Dorsal soft rays (total): 9; Anal spines: 3; Anal soft rays: 8. This species is distinguished by the following characters: body moderately deep, its depth 2.3-2.5 times in standard length; head length 0.8-1.0 times in body depth, 2.5-2.8 times in SL, dorsal profile near eye nearly straight or slightly convex; snout moderately short, its length about 1.9-2.2 times in head length, measured without the lip the snout is 0.9-1.0 times in cheek height, its dorsal profile concave, snout angle relative to upper jaw between 53° and 64°; interorbital space convex or almost flat; posterior nostril an oblong longitudinal opening, closer to orbit than anterior nostril; eye situated close to or slightly removed from dorsal profile, its length 3.3-4.6 times in HL; cheek moderately high, its height 2.1-2.7 times in HL; lateral teeth in jaws of adults molars or rounded; outer surface of maxilla usually smooth; D X,9, the 4th or 5th dorsal-fin spine the longest, its length 2.7-3.3 times in body depth; A III,8 with the 3rd, 4th or 5th soft ray usually the longest, its length much longer than length of base of soft-rayed portion of anal fin and 0.7-1 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; 44-46 lateral-line scales; 4 ½ scale rows between lateral line and base of middle dorsal-fin spines; 15-17 scale rows in transverse series between origin of anal fin and lateral line; usually 15 rows in lower series of scales around caudal peduncle; 5-9 scales in supratemporal patch; inner surface of pectoral-fin base densely covered with scales; posterior angle of operculum fully scaly. Colour of head and body brown or rust red, lighter ventrally; sometimes 2 light bars on caudal peduncle; area around eye, a broad streak from eye to tip of snout, lips, and base of pectoral fins red; all fins reddish, often a bright red or orange (Ref. 114226).
Occurs over coral reefs and adjacent sandy areas. May be solitary or in small groups. Feeds on echinoderms, mollusks, crustaceans, and small fish. Caught mostly by handlines and traps. Marketed fresh. Also caught with handlines (Ref. 9775, 687103).
