Short description Morphology | Morphometrics

Dorsal spines (total): 7; Dorsal soft rays (total): 8-9; Anal spines: 1; Anal soft rays: 8 - 9. Diagnosis: Seven large regular orange red bars along the side of the body; a dark spot on the lower base of the pectoral fin, and another on the lower peduncle; internal pigmentation on the dorsal surface of the head just behind eyes well-developed but broadly diffused, not forming a discreet bar. Predorsal scales absent. Second dorsal spine slightly to very elongate. A moderate interorbital and variably-developed postorbital trench. The fifth pelvic fin ray is unbranched and 50-70% of the length of the fourth.

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00891 (0.00419 - 0.01894), b=3.07 (2.90 - 3.24), 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) .
