Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 7; Dorsal soft rays (total): 7 - 9; Anal spines: 1; Anal soft rays: 7 - 8. This species is distinguished by having predorsal scales; second and third dorsal spines not elongated; with interorbital and postorbital trenches; opercular scales 2; a single dichotomous branch in the fifth pelvic-fin ray; when alive has three or four rows of yellow to orange blotches along the body and a narrow red bar on the vertical limb of the preopercle (Ref. 59340); characterized further by having longitudinal scale series 21-25; predorsal scales 4-5; cheek without scales; depth of body 4.3 in SL (Ref. 90102).

Collected specimens came from patch reefs and coral slopes with diverse coral cover, except for the 3 specimens collected from a steep (45°) wall of large boulders with little algal or coral growth (Ref. 59340).

Estimates based on models

Preferred temperature (Ref. 123201): 28.6 - 29.3, mean 29 °C (based on 446 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01023 (0.00477 - 0.02194), b=3.01 (2.83 - 3.19), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Resilience (Ref. 120179): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
