Short description
Dorsal spines (total): 10; Dorsal soft rays (total): 13 - 14; Anal spines: 3; Anal soft rays: 8. Dorsal profile of head steeply sloped. Preorbital bone broad, much wider than eye diameter. Preopercular notch and knob well developed. Scale rows on back rising obliquely, both above and below the lateral line. Generally red or gray, darker on back and upper portion of the head, with orange hue on the lower part of the opercle and in the pectoral axil. The fins are red, or frequently brown to blackish.

Biology
    Glossary (e.g. epibenthic)
Mainly inhabit coral reefs, sometimes forming large aggregations, which are mostly stationary during the day. Juveniles occur in seagrass beds, also in mixed sand and coral habitats of shallow sheltered reefs (Ref. 1602). Sub-adults commonly form very large schools that are stationary or drift slowly along slopes during the day. Large individuals along coastal slopes at moderate depths (Ref. 48635). Benthopelagic (Ref. 58302). Feed on fishes, and a variety of invertebrates including shrimps, crabs, lobsters, stomatopods, cephalopods, echinoderms and ophiuroids (Ref. 55).
