Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 12 - 15; Dorsal soft rays (total): 8 - 10; Anal spines: 1; Anal soft rays: 16 - 19. 9-12 spines in the second dorsal fin, 8-10 rays in the third dorsal fin, 17-20 anal fin rays, 32-37 + 1 lateral scale rows, 13-19 + 17-22 lateral line scales, two median mandibular pores, a black band on the caudal peduncle, about 9 basal dark spots on the female's anal fin, and a overall blackish coloration of the male.

Adults inhabit rock and coral reefs (Ref. 90102), from the surface to 15 m, including intertidal pools (Ref. 13227). Eggs are hemispherical and covered with numerous sticky threads that anchor them in the algae on the nesting sites (Ref. 240). Larvae are planktonic which occur primarily in shallow, nearshore waters (Ref. 94114).

Estimates based on models

Preferred temperature (Ref. 123201): 24.7 - 29.4, mean 28.2 °C (based on 895 cells).

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

Bayesian length-weight: a=0.00562 (0.00258 - 0.01228), b=3.08 (2.89 - 3.27), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.1 ±0.3 se; based on size and trophs of closest relatives

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).
