身體是黃灰色的有分散的不規則的深色斑點; 唇淡黃色的, 上嘴唇更密集; 在胸鰭的上面基底的一個紅色的斑點。 鰭是藍灰色而有斑點的,鰭的基底是顏色淡的，而且背鰭與尾鰭的邊緣是淡紅的。
Occurs in small groups over seagrass beds, sand and rubble areas of coral reefs, deep channels, and lagoons. Usually found in shallow water to depths of 150 m. Usually seen solitary but sometimes swims in small groups. Juveniles in seagrass beds (Ref. 48635). Feeds mainly on crustaceans, fishes, and echinoderms. Caught mostly with handline, traps,
and trawl (Ref. 114226). Minimum depth reported taken from Ref. 128797.
形成小群魚群海草床之上，珊瑚礁，深的峽道與潟湖的沙子與碎石區。 通常發現於淺水區。 通常單獨的被看到但是有時群游於小群魚群中。 稚魚在海草床。 (參考文獻 48635) 主要吃甲殼動物，魚與棘皮動物。
