Short description Morphology | Morphometrics

Dorsal spines (total): 6 - 7; Dorsal soft rays (total): 8-10; Anal spines: 1; Anal soft rays: 8 - 9. Distinguished by the combination of the following features: no predorsal scales anterior extension of body scales along the side of the nape from half-way between the eye and the shoulder spot in juveniles to just behind the eye in adults; body light brown with orange spots or stripes on the head, a dark greyish orange shoulder spot above pectoral fin base, and scale pockets strongly outlined with dark brown chromatophores with an orange spot at the junction between adjacent pockets in the same longitudinal row (Ref. 51083).

Biology     Glossary (e.g. epibenthic)

Estimates of some properties based on models

Preferred temperature (Ref. 115969): 28.4 - 29.3, mean 28.8 (based on 732 cells; Ref. 115970).
Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00891 (0.00412 - 0.01928), b=3.08 (2.91 - 3.25), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Resilience (Ref. 69278):  High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153):  Low vulnerability (10 of 100) .
