Short description Identification keys | Morphology | Morphometrics
Dorsal spines (total): 9; Dorsal soft rays (total): 10; Anal spines: 3; Anal soft rays: 9; Vertebrae: 25. Head and body gray-brown with darker scale edges, paler ventrally. Numerous dark spots on scales on operculum and region circumscribed by pectoral fin. Flexible dorsal spines; caudal fin rounded in juveniles, double emarginate in adults; pectoral fin base yellowish, the rest unpigmented; pale pelvic fins with 2 reddish bars, at the center and near the base. Skin dark, almost black around anus. Orangish iris.
Inhabits coral and rocky reefs and grass bed areas to depths of about 30 m (Ref. 9710). Occurs singly or in small groups (Ref. 9710). Feeds mainly on marine angiosperms and epiphytic algae. Caught mainly with traps, nets and other types of artisanal gear.

Estimates based on models
Preferred temperature (Ref. 123201): 24.8 - 29.2, mean 27.5 °C (based on 233 cells).
Phylogenetic diversity index (Ref. 82804): PD50 = 0.5312 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.02089 (0.00803 - 0.05439), b=2.98 (2.75 - 3.21), 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 (16 of 100).
Nutrients (Ref. 124155): Calcium = 52.4 [20.4, 149.7] mg/100g; Iron = 0.709 [0.277, 1.756] mg/100g; Protein = 18 [16, 20] %; Omega3 = 0.066 [0.029, 0.146] g/100g; Selenium = 13.2 [4.0, 39.6] μg/100g; VitaminA = 42.1 [9.8, 167.6] μg/100g; Zinc = 2.25 [1.06, 4.02] mg/100g (wet weight);
