生態學
海洋 礁區魚類; 非遷移的; 深度上下限 10 - 200 m (Ref. 2295). 熱帶; 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.
印度-西太平洋: 廣泛分佈, 包括紅海 , 波斯灣, 東非到斯里蘭卡，到琉球群島與巴布亞新幾內亞。 也記錄自密克羅尼西亞 (參考文獻 3807) 與法屬玻里尼西亞 (參考文獻 4517) ，但是這些是可能是 尖吻裸頰鯛〔Lethrinus olivaceus〕 的誤鑑.
Length at first maturity / 大小 / 重量 / 年齡
Maturity: Lm 29.1 range ? - ? cm
Max length : 80.0 cm TL 雄魚/尚未辨別雌雄; (Ref. 48635); common length : 40.0 cm TL 雄魚/尚未辨別雌雄; (Ref. 2295); 最大體重: 4.9 kg (Ref. 40637)
背棘 (總數): 10; 背的軟條 (總數): 9; 臀棘 3; 臀鰭軟條: 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.
吻部是中等長度的,它的背面輪廓些微地凹曲。 體色是藍灰色的，否則褐色時常在側邊上有分散的不規則的黑色斑塊; 有時三個深色條紋向前呈放射狀從眼。 鰭是灰白或橘色的。
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.
發現在在珊瑚礁附近的沙地上了。 (參考文獻 30573) 吃魚，甲殼動物，頭足類動物與多毛類動物。 形成小群魚群群游有時伴隨著 L. 橄欖色的 . 作為食用魚。
