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). 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。
