生态学
海洋 礁区鱼类; 深度上下限 20 - 200 m (Ref. 9626), usually 80 - 150 m (Ref. 55). ; 43°N - 3°S, 100°W - 38°W (Ref. 55227)
Western Atlantic: as far north as North Carolina, USA and Bermuda south to Trinidad and northern Brazil; including the Gulf of Mexico (Ref. 9626). Very common in the Caribbean, particularly the Antilles.
Length at first maturity / 大小 / 重量 / 年龄
Maturity: Lm 28.7, range 21 - 25 cm
Max length : 75.0 cm TL 雄鱼/尚未辨别雌雄; (Ref. 9710); common length : 50.0 cm TL 雄鱼/尚未辨别雌雄; (Ref. 55); 最大体重: 14.0 kg (Ref. 9710)
背棘 (总数): 10; 背的软条 (总数): 14; 臀棘 3; 臀鳍软条: 8. Preopercular notch and knob weak. Scale rows on back rising obliquely above lateral line. Mainly scarlet red, silvery on lower sides and belly; fins are yellowish to orange. A prominent black blotch is at the base and in axil of pectoral fins.
Adults inhabit deeper waters over sandy or rocky bottoms and near drop-offs and ledges. Young occur in shallower water, often between about 35 and 50 m. Feed mainly on fishes. Good food fish, it is marketed mostly fresh (Ref. 55).
