大小 / 重量 / 年齡
Maturity: Lm ? range ? - ? cm
Max length : 48.0 cm TL 雄魚/尚未辨別雌雄; (Ref. 55); common length : 38.0 cm TL 雄魚/尚未辨別雌雄; (Ref. 55); 最大體重: 1.3 kg (Ref. 26340); 最大年齡: 18 年 (Ref. 115050)
背棘 (總數): 10; 背的軟條 (總數): 11-12; 臀棘 3; 臀鰭軟條: 8. Lower jaw projecting slightly beyond upper jaw; lower corner of preopercle greatly projecting and strongly serrated. Preorbital bone broad, maxilla extending nearly to mid-eye level. Preopercular notch and knob moderate. Scale rows on back rising obliquely above lateral line. Back and upper side gray to dark olive grading to silvery ventrally. Usually with a black spot, about eye size, on lateral line below the anterior soft dorsal-fin rays.
Adults inhabit clear shallow waters over rocky bottoms in the vicinity of coral reefs, less frequently in sandy or seagrass areas. They often form large aggregations during the day. They feed at night mainly on small fish, shrimps, crabs and cephalopods (Ref. 78464).
