Max length : 90.0 cm TL オス/雌雄の選別がない; (Ref. 9987); common length : 76.0 cm SL オス/雌雄の選別がない; (Ref. 37816); 最大公表体重: 12.5 kg (Ref. 4699); 最大記録サイズ: 55 年 (Ref. 72420)
背面の脊椎 (合計): 10; 背鰭 (合計): 13-14; 肛門の骨 3; 臀鰭: 8. This species is distinguished by the following characters: moderately deep body, its greatest depth 2.4-2.9 in SL; distinct groove or pit from nostrils to the front of the eye; preopercular notch and knob moderately developed; vomerine tooth patch narrow crescentic, without a medial posterior extension; gill rakers of first gill arch 6-7 + 16 = 22-23 (including rudiments). Colour of body dark reddish-brown with faint dark stripes; young and some adults with two silvery-white spots on back; pectoral fins pink with dorsal edge prominently black; juveniles sometimes have caudal end of body and the tail white. mimicking Chromis damselfishes (Ref. 9821, 90102).
Adults inhabit coral reefs, including sheltered lagoons and outer reefs (Ref. 30573). Usually found singly, often adjacent to steep outer reef slopes, but occasionally found in groups (Ref. 9710). Feeds mainly on fishes, but also take shrimps, crabs, amphipods, stomatopods, gastropods and urochordates. Large fish from oceanic areas in the western Pacific are often ciguatoxic, e.g., in Tuvalu (Ref. 9513). Caught mainly with handlines and bottom longlines (Ref. 9821). Utilized fresh and dried-salted (Ref. 9987). Juveniles mimic Chromis damselfishes (Ref. 90102).
