Dorsal spines (total): 12; Dorsal soft rays (total): 15-16; Anal spines: 2; Anal soft rays: 13

Adults inhabit rocky reefs (Ref. 9334). Territorial herbivore, feed on farmed turf-algae within their territories (Ref. 57615). 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): 22.3 - 28.6, mean 26.2 °C (based on 223 cells).

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

Bayesian length-weight: a=0.01950 (0.00901 - 0.04219), b=2.99 (2.81 - 3.17), in cm total length, based on LWR estimates for this Genus-BS (Ref. 93245).

Trophic level (Ref. 69278): 2.0 ±0.00 se; based on food items.

Generation time: 1.4 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.

Resilience (Ref. 120179): Low, minimum population doubling time 4.5 - 14 years (tmax=32).

Fishing Vulnerability (Ref. 59153): Low vulnerability (18 of 100).

Nutrients (Ref. 124155): Calcium = 114 [58, 186] mg/100g ; Iron = 0.914 [0.539, 1.544] mg/100g ; Protein = 18.2 [16.9, 19.4] % ; Omega3 = 0.0936 [, ] g/100g ; Selenium = 31.1 [16.4, 64.6] μg/100g ; VitaminA = 39.3 [9.2, 158.9] μg/100g ; Zinc = 1.94 [1.28, 2.90] mg/100g (wet weight);
