Descrição breve Chaves de identificação | Morfologia | Morfometria

Espinhos dorsais (total) : 12; Raios dorsais moles (total) : 15 - 16; Espinhos anais: 2; Raios anais moles: 12 - 13. Exhibits geographic color variations.

Adults inhabit coral and rocky reefs (Ref. 9334). Omnivorous (Ref. 9334). Adults are territorial and aggressive, vigorously driving off other fishes and certain invertebrates from their feeding and reproductive territories. They graze on algae and invertebrates including tubeworms, small crustaceans, and the tentacles of anemones (Ref. 28023). 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): 23.5 - 28.1, mean 24.4 °C (based on 27 cells).

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

Bayesian length-weight: a=0.01950 (0.00893 - 0.04257), b=2.99 (2.81 - 3.17), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).

Nível Trófico (Ref. 69278): 3.0 ±0.39 se; based on food items.

Generation time: 1.5 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.

Resiliência (Ref. 120179): Baixo, tempo mínimo de duplicação da população 4,5 - 14 anos (tmax=27).

Fishing Vulnerability (Ref. 59153): Low vulnerability (19 of 100).

Nutrients (Ref. 124155): Calcium = 108 [57, 166] mg/100g; Iron = 0.778 [0.466, 1.256] mg/100g; Protein = 18.4 [17.3, 19.5] %; Omega3 = 0.112 [0.069, 0.179] g/100g; Selenium = 24.3 [13.9, 45.4] μg/100g; VitaminA = 72.6 [21.9, 237.1] μg/100g; Zinc = 1.61 [1.09, 2.29] mg/100g (wet weight);
