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.

背棘 (总数) : 10; 背的软条 (总数) : 9; 臀棘: 3; 臀鳍软条: 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.
吻部是中等长度的,它的背面轮廓些微地凹曲。 体色是蓝灰色的，否则褐色时常在侧边上有分散的不规则的黑色斑块; 有时三个深色条纹向前呈放射状从眼。 鳍是灰白或橘色的。

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.
