Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 9; Dorsal soft rays (total): 26 - 28; Anal spines: 3; Anal soft rays: 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).

Biology     Glossary (e.g. epibenthic)

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).

Estimates based on models

Preferred temperature (Ref. 115969): 24.5 - 28.4, mean 27.5 (based on 214 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.02344 (0.01103 - 0.04981), b=2.96 (2.79 - 3.13), in cm Total Length, based on LWR estimates for this Genus-body shape (Ref. 93245).
Trophic level (Ref. 69278):  2.0   ±0.00 se; based on food items.
Resilience (Ref. 120179):  Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Moderate vulnerability (40 of 100).
