Espinas dorsales (total) : 9; Radios blandos dorsales (total) : 26 - 28; Espinas anales: 3; Radios blandos anales: 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).
Body shape (shape guide): short and / or deep; Cross section: compressed.
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).
