Max length : 90.0 cm TL पुल्लिंग / अलिंग; (Ref. 9987); common length : 76.0 cm SL पुल्लिंग / अलिंग; (Ref. 37816); अधिकतम प्रकाशित वज़न: 12.5 kg (Ref. 4699); अधिकतम सूचित उम्र: 55 वर्षो (Ref. 72420)
पृष्ठीय रीढ़ (सम्पूर्ण): 10; पृष्ठीय सौफट रेज़ (सम्पूर्ण): 13-14; गुदा कांटा 3; ऐनल सौफट रेज़: 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). Minimum depth reported taken from Ref. 128797.
