Ekologi
marina bottenlevande; djupintervall 26 - 340 m (Ref. 9626), usually 70 - 120 m (Ref. 55). Tropical; 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.

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.
