Max length : 60.0 cm TL 雄魚/尚未辨別雌雄; (Ref. 26938); common length : 35.0 cm TL 雄魚/尚未辨別雌雄; (Ref. 55); 最大體重: 3.2 kg (Ref. 40637); 最大年齡: 10 年 (Ref. 3090)
背棘 (總數): 12 - 13; 背的軟條 (總數): 10-11; 臀棘 3; 臀鰭軟條: 8. Snout short, lower jaw slightly projecting. Mouth small. Pectoral fins relatively short, not reaching level of anus. Scale rows on back rising obliquely above lateral line. Back and upper sides vermilion, shading to silvery with reddish tinge ventrally, with narrow horizontal yellow lines below the lateral line. The dorsal and caudal fins yellowish; the anal and pelvic fins whitish.
Adults are found in moderately deep waters, most common over rock, gravel or sand bottoms near the edge of the continental and island shelves, often in large schools. Young fish occur in shallower depths (below 25 m), also often forming large schools. They feed on fishes, shrimps, crabs, polychaetes, other benthic invertebrates, cephalopods and planktonic organisms. Good food fish (Ref. 9626).
