Short description Morphology | Morphometrics

Dorsal spines (total): 7; Dorsal soft rays (total): 9-10; Anal spines: 1; Anal soft rays: 8. The species is characterized by the absence of scales on the cheek, opercle and midline of the nape; fifth pelvic fin ray branched sequentially once; a moderate interorbital trench; a short and narrow postorbital trench; color of living specimens red with a white belly, a large brown-black spot larger than the eye immediately above the pectoral fin base and numerous smaller dark spots across the nape; and in preserved specimens the dark spots remain but the ground color is yellow. Differs from its congeners by the very large 1.25 eye diameter brown-black spot above the pectoral fin base and the rows of smaller brown spots on the nape separated by a honeycomb pattern (Ref. 59339).

Estimates of some properties based on models

Preferred temperature (Ref. 115969): 27.9 - 28.7, mean 28.4 (based on 4 cells).
Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00871 (0.00412 - 0.01842), b=3.09 (2.92 - 3.26), 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) .
