生態學
海洋 居於水底的; 深度上下限 70 - 100 m. 熱帶; 22°N - 20°S, 49°E - 94°E (Ref. 55)
Indian Ocean: known only from Madagascar, Sri Lanka, and the Bay of Bengal, but probably widespread in the tropical region. This species has been frequently confused with other large red snappers such as Lutjanus malabaricus and Lutjanus sanguineus.
印度洋: 已知只來自馬達加斯加，斯里蘭卡與孟加拉灣了, 但是可能在熱帶的區域中廣泛分佈。 這種曾經時常與其他的大紅色的笛鯛例如 Lutjanus malabaricus 與 Lutjanus sanguineus 互相混淆。

Preopercular notch and knob poorly developed. Scale rows on back rising obliquely above lateral line. Color is red or reddish-orange, sometimes with an indistinct saddle-like black blotch on the caudal peduncle behind the dorsal fin. Median fins are reddish, sometimes with a yellow suffusion or narrow brown or black borders; pelvic fins are red; pectoral fins yellow.
