Ambiente: milieu / zona climatica / distribuzione batimetrica / gamma di distribuzione
Ecologia
marino associati a barriera corallina; non migratori; distribuzione batimetrica 10 - 200 m (Ref. 2295). Tropical; 32°N - 23°S, 32°E - 160°E
Indo-West Pacific: widespread, including the Red Sea, Arabian (Persian) Gulf, East Africa to Sri Lanka, to the Ryukyu Islands and Papua New Guinea. Also recorded from Micronesia (Ref. 3807) and French Polynesia (Ref. 4517) but these are probably misidentifications of Lethrinus olivaceus.

Max length : 80.0 cm TL maschio/sesso non determinato; (Ref. 48635); common length : 40.0 cm TL maschio/sesso non determinato; (Ref. 2295); peso massimo pubblicato: 4.9 kg (Ref. 40637)
Spine dorsali (totale) : 10; Raggi dorsali molli (totale) : 9; Spine anali: 3; Raggi anali molli: 8. The snout is moderately long, its dorsal profile slightly concave. Body color is bluish gray or brown often with scattered irregular dark blotches on sides; sometimes three dark streaks radiate forward from the eye. The fins are pale or orangish.
Body shape (shape guide): fusiform / normal; Cross section: oval.
Found over sandy areas near coral reefs (Ref. 30573). Feeds on fish, crustaceans, cephalopods, and polychaetes. Swims in small schools sometimes together with L. olivaceous. Utilized as a food fish. Maximum depth reported taken from Ref. 9773.
