Short description Morphology | Morphometrics

Dorsal spines (total): 9; Dorsal soft rays (total): 31-33; Anal spines: 3; Anal soft rays: 23 - 25. Pale gray around mouth, and pale gray margin on caudal fin. Inside of pectoral fin yellow (Ref. 26938). Juveniles are black with two light yellow bars on body and three on head; caudal fin yellow with a vertically elongate, nearly rectangular or hemispherical black spot in middle (Ref. 13442).

Biology     Glossary (e.g. epibenthic)

Common in coral reefs, usually solitary, occasionally in pairs. Juveniles are part-time cleaners. Feed mainly on sponges, but also takes tunicates, algae, zoantharians, gorgonians, hydroids, bryozoans, and seagrasses. Oviparous (Ref. 240), monogamous (Ref. 52884). Flesh reported to be of excellent quality (Ref. 3797); marketed fresh and salted (Ref. 5217). Friendly toward divers (Ref. 9710). Have been reared in captivity (Ref. 35419).

Life cycle and mating behavior Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae

Monogamous mating is observed as both facultative and social (Ref. 52884).
