生态学
; 海洋 居于水底的; 深度上下限 26 - 340 m (Ref. 9626), usually 70 - 120 m (Ref. 55). , preferred 27°C (Ref. 107945); 25°N - 19°S, 87°W - 35°W (Ref. 54572)
Western Atlantic: throughout most of the Caribbean Sea from Cuba southward to northeastern Brazil. Frequently confused with Lutjanus campechanus. Also referred to as Lutjanus aya by past authors, but Rivas (Ref. 6409) proved that Bodianus aya Bloch, 1790 is not a lutjanid, but probably a sciaenid.
Length at first maturity / 大小 / 重量 / 年龄
Maturity: Lm 43.0, range 79 - 40.6 cm
Max length : 100.0 cm TL 雄鱼/尚未辨别雌雄; (Ref. 55); common length : 65.0 cm TL 雄鱼/尚未辨别雌雄; (Ref. 55); 最大体重: 10.0 kg (Ref. 5217); 最大年龄: 18 年 (Ref. 55)
背棘 (总数): 10; 背的软条 (总数): 14; 臀棘 3; 臀鳍软条: 8 - 9. Head short, its dorsal profile somewhat rounded behind eye. Snout short and blunt. Eye large. Preopercular notch and knob weak. Pectoral fins long, reaching level of anus. Scale rows on back rising obliquely above lateral line. Back and upper side deep red; lower sides and belly rosy, with a silvery sheen; the fins mainly red. A small spot is sometimes on the lateral line below the anterior portion of the dorsal fin rays. Young with a rounded black spot on upper side below anterior dorsal soft rays, disappearing with growth.
Adults inhabit rocky areas. They feed mainly on fishes, shrimps, crabs, cephalopods and planktonic items.
