Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 12 - 13; Dorsal soft rays (total): 15 - 17; Anal spines: 2; Anal soft rays: 12 - 13. Body color is medium brown, sometimes with slight diffusion of yellow. The edges of scales are narrowly bordered with dusky brown. The suborbital is lavender or blue and the lips are pale gray. The pectoral fins are translucent with brownish rays and yellow suffusion on posterior edge. A prominent black spot bordered with light blue is on the outer part of anterior dorsal spines running from base of 1st spine to distal tip of 5th or 6th spine.

Biology     Glossary (e.g. epibenthic)

Adults usually inhabit rocky reefs (Ref. 7247). Oviparous, distinct pairing during breeding (Ref. 205). Eggs are demersal and adhere to the substrate (Ref. 205). Males guard and aerate the eggs (Ref. 205).

Estimates based on models

Preferred temperature (Ref. 123201): 18.3 - 25.2, mean 21.4 °C (based on 155 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01259 (0.00497 - 0.03190), b=3.04 (2.82 - 3.26), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  2.0   ±0.00 se; based on food items.
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).
Nutrients (Ref. 124155):  Calcium = 65.5 [24.5, 123.1] mg/100g; Iron = 0.787 [0.436, 1.375] mg/100g; Protein = 19.1 [17.9, 20.2] %; Omega3 = 0.19 [0.10, 0.34] g/100g; Selenium = 10.7 [5.1, 24.0] μg/100g; VitaminA = 64.5 [17.4, 235.5] μg/100g; Zinc = 1.49 [0.95, 2.34] mg/100g (wet weight);
