生態學
海洋 居於水底的; 深度上下限 26 - 340 m (Ref. 9626), usually 70 - 120 m (Ref. 55). 熱帶; 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.
西大西洋: 在大部分的加勒比海各處從古巴向南至巴西東北部。 時常與 Lutjanus campechanus 互相混淆了。 也被歸屬於 Lutjanus aya 由過去的命名者, 但是 Rivas(參考文獻 6409) 證明 Bodianus aya Bloch,1790 不是一個 lutjanid, 但是可能一個石首魚科魚類。
Length at first maturity / 大小 / 重量 / 年齡
Maturity: Lm 43.0, range 42 - ? cm
Max length : 100.0 cm TL 雄魚/尚未辨別雌雄; (Ref. 55); common length : 65.0 cm TL 雄魚/尚未辨別雌雄; (Ref. 55); 最大體重: 10.0 kg (Ref. 5217); 最大年齡: 18 年 (Ref. 55)
背棘 (總數) : 10; 背的軟條 (總數) : 14; 臀棘: 3; 臀鰭軟條: 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.
頭部短, 它的背面輪廓略微圓的在後眼。 吻短與鈍的。 眼大的。 前鰓蓋骨凹槽與癤瘤弱的。 胸鰭長的, 達到肛門高度。 鱗片列背面斜向上升在側線上面。 背面與上側面深的紅色; 下側與腹面玫瑰紅色的, 具有一個銀色的光輝; 鰭主要紅色。 一種小的斑點有時在側線上在背鰭鰭條的前部之下。 在前面的背鰭軟條之下在上側面上幼魚有一個圓形的黑色斑點,隨著成長而消失。
Adults inhabit rocky areas. They feed mainly on fishes, shrimps, crabs, cephalopods and planktonic items.
棲息於岩石區。 主要吃魚，蝦，螃蟹，頭足類動物與浮游生物項目。
