Short description Morphology | Morphometrics

Dorsal spines (total): 8; Dorsal soft rays (total): 25-28; Anal spines: 3; Anal soft rays: 22 - 25. Yellow on edge of orbit broad and conspicuous (pale in preservative), especially posteriorly. Small spots on head blue, not extending onto anterior body or chest. Posterior gill rakers 30-36 (Ref 42056).

Benthopelagic over coral, rock, and rubble (Ref. 58302). Solitary. Mainly diurnal (Ref. 4887). Feeds on detritus by whisking its comb-like teeth over the bottom as it closes its mouth (Ref. 3921).

Estimates based on models

Preferred temperature (Ref. 115969): 24.4 - 28.9, mean 27.4 (based on 382 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5020 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.02291 (0.01363 - 0.03849), b=3.03 (2.89 - 3.17), in cm Total Length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Resilience (Ref. 120179): High, minimum population doubling time less than 15 months (K=0.9).

Fishing Vulnerability (Ref. 59153): Low to moderate vulnerability (28 of 100).
