Etymology: Lutjanus: Malay, ikan lutjan, name of a fish.
Environment: milieu / climate zone / depth range / distribution range
Ecologia
marinhas demersal; intervalo de profundidade 70 - 100 m. Tropical; 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.

Maturity: Lm ? range ? - ? cm
Max length : 60.0 cm TL macho/indeterminado; (Ref. 55); common length : 55.0 cm TL macho/indeterminado; (Ref. 5450)
Espinhos dorsais (total) : 10 - 11; Raios dorsais (total) : 13 - 14; Espinhos anais: 3; Raios anais : 9. Dorsal profile of head steeply sloped. Preorbital bone relatively broad, its width greater than eye diameter. 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.
