Indo-West Pacific: Red Sea and East Africa to the Ryukyu Islands and New Caledonia. Recently reported from Tonga (Ref. 53797). Also reported from French Polynesian islands (Ref. 4795) but this is a misidentification of Lethrinus rubrioperculatus (Ref. 2295).
印度-西太平洋: 红海而且东非到琉球群岛与新加勒多尼亚。 最近记录自东加。 (参考文献 53797) 也记录自法属玻里尼西亚岛 (参考文献 4795) ,但是这是一个 红鳃龙占〔Lethrinus rubrioperculatus〕 的错误鉴定。 (参考文献 2295)

生物学特性     字汇 (例如 epibenthic)

Inhabits sandy and weedy areas near coral reefs, solitarily or in groups (Ref. 30573, 90102), where it is well camouflaged and usually swims in the cover of the substrate (Ref. 48635). Juveniles sometimes abundant in shallow, weedy areas (Ref. 4369). Solitary or in small groups (Ref. 90102). Feeds on small benthic invertebrates (Ref. 30573). A protogynous hermaphrodite (Ref. 55367). Flesh of large individuals is esteemed (Ref. 4369).

栖息于在珊瑚礁 (参考文献 30573) 附近的沙而杂草丛生的区域, 在那里它是善于伪装而且通常在底部的表面中游泳.(参考文献 48635) 稚鱼有时丰富的在水浅又杂草丛生的区域中.(参考文献 4369) 吃小型底栖的无脊椎动物。 (参考文献 30573) 一个雌性先熟的雌雄同体.(参考文献 55367) 大个体的肉被赞赏。 (参考文献 4369)
