Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 13; Dorsal soft rays (total): 15; Anal spines: 3; Anal soft rays: 12. Bluish grey with blackish margin on gill cover; diagnostic white patch just in front of each eye (Ref. 11482).

Usually seen in aggregations while grazing over shallow reefs (Ref. 11482). May also mix with schools of other species (Ref. 5227).The fine mat of comb-like, bicuspid and tricuspid teeth are used to scrape algae from rocks and corals (Ref. 28023).

Estimates based on models

Preferred temperature (Ref. 123201): 19.9 - 24.4, mean 23 °C (based on 47 cells).

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

Bayesian length-weight: a=0.01479 (0.00674 - 0.03244), 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): 2.0 ±0.00 se; based on food items.

Resilience (Ref. 120179): Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low to moderate vulnerability (35 of 100).

Nutrients (Ref. 124155): Calcium = 49.3 [23.9, 88.7] mg/100g; Iron = 0.587 [0.349, 1.000] mg/100g; Protein = 18.2 [16.9, 19.5] %; Omega3 = 0.0752 [, ] g/100g; Selenium = 29.1 [15.0, 60.9] μg/100g; VitaminA = 40.2 [9.0, 162.8] μg/100g; Zinc = 1.41 [0.95, 2.12] mg/100g (wet weight);
