Maturity: Lm ? range ? - ? cm
Max length : 50.0 cm TL 雄魚/尚未辨別雌雄; (Ref. 2334)
背棘 (總數) : 9; 背的軟條 (總數) : 26 - 28; 臀棘: 3; 臀鰭軟條: 25 - 26. Body brown; a round black spot at upper gill opening; dark blue line just below the bases of dorsal and anal fins. Dorsal fin with soft part having longer base than spinous part. Minute scales. Gill rakers in anterior row 19-23, posterior 22-24. A dark brown area surrounding the caudal spine. Large males develop highly convex foreheads that extend beyond the mouth (Ref. 1602).
Occurs in clear seaward reef slopes, below 15 m, usually below 30 m (Ref. 9710). Adults mainly on deep coastal reef slopes and outer reef walls (Ref. 48637). Found singly or in pairs (Ref. 9710). Feeds on algal film on bare rocks (Ref. 9710). Juveniles found in shallow protected reefs, usually between soft coral, in 0.2-3 m depth (Ref. 9710).
出現於清澈的臨海礁石斜坡,在 15 公尺之下, 通常在 30 公尺之下.(參考文獻 9710) 各別地或成對發現。 (參考文獻 9710) 在裸露的岩石上吃海藻的薄膜。 (參考文獻 9710) 稚魚發現於水淺且有遮蔽礁區了, 通常在軟珊瑚之間, 在 0.2-3 公尺深中.(參考文獻 9710)
