البيئة
بحري مرتبطة بالشعاب; غير مهاجرة; نطاق العمق 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.
Length at first maturity / الحجم / وزن / العمر
Maturity: Lm 29.1 range ? - ? cm
Max length : 80.0 cm TL ذكر/ مختلط الجنس; (Ref. 48635); common length : 40.0 cm TL ذكر/ مختلط الجنس; (Ref. 2295); أعلا وزن تم نشرة: 4.9 kg (Ref. 40637)
الأشواك الظهرية (المجموع) : 10; الأشعة الظهرية الناعمة (المجموع) : 9; شوكة شرجية: 3; أشعه شرجية لينه: 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.
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.
