生態学
海 関連する礁; 移住性ではない; 深さの範囲 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 / サイズ / 重さ / 年齢
Maturity: Lm 29.1 range ? - ? cm
Max length : 80.0 cm TL オス/雌雄の選別がない; (Ref. 48635); common length : 40.0 cm TL オス/雌雄の選別がない; (Ref. 2295); 最大公表体重: 4.9 kg (Ref. 40637)
背面の脊椎 (合計) : 10; 背鰭 (合計) : 9; 肛門の骨: 3; 臀鰭: 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.
