頰沒有鱗片。 身體與頭部是褐色或灰色的, 變成腹部顏色較淡。 在胸鰭的基底與鰓蓋的邊緣上面的唇與小區塊是紅色的。 鰭是橘色的﹐暗色的或有斑點的。
Solitarily inhabits sand, rubble, and weed areas near corals (Ref. 90102) in deep reefs. Feeds on crustaceans and small fishes. Gonads in spawning state have been observed in October. This species is not well represented in museums due to the relatively large capture size for most specimens (Ref. 2295). Also caught with handlines (Ref. 9775).
棲息於深的礁。 吃甲殼動物與小魚。 在產卵狀態的生殖腺曾經在十月觀察。 這種很好地不在博物館被代表為大多數的標本由於相當大的抓取大小.(參考文獻 2295) 也用手執的釣絲捕獲。 (參考文獻 9775)
