Краткое описание
определительные ключи | морфология | морфометрия
колючие лучи спинного плавника (общее число) : 12; членистые (мягкие) лучи спинного плавника (общее число) : 15 - 16; колючие лучи анального плавника: 2; членистые (мягкие) лучи анального плавника: 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): PD
50 = 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).
Trophic level (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.
устойчивость к внешним воздействиям (Ref.
120179): низкий, минимальное время удвоения популяции 4.5-14 лет (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);
