Short description

Dorsal spines (total): 10; Dorsal soft rays (total): 9; Anal spines: 3; Anal soft rays: 8. The caudal fin is only slightly forked with the tips rounded. The inner surface of the pectoral fin is densely scaled; the posterior angle of the operculum is fully scaled. The head and body is brown or rust red, becoming lighter ventrally. Sometimes there are two light bars on the peduncle. A broad white streak originates from the eye and ends at the tip of the snout. The lips and the base of the pectoral fin are red. The fins are reddish, often bright red or orange.

Occurs over coral reefs and adjacent sandy areas. May be solitary or in small groups. Feeds on echinoderms, mollusks, crustaceans, and small fish. Also caught with handlines (Ref. 9775). Marketed fresh (Ref. 9775).
