Tamaño / Peso / Age

Maturity: L_m ? range ? - ? cm
Max length : 32.0 cm TL macho / no sexado; (Ref. 55763); common length : 20.0 cm TL macho / no sexado; (Ref. 55763)

Abundant in shallow coastal areas, especially in rocky coasts with macroalgae. May be solitary or swim in loose schools (Ref. 5227). Feeds by scraping or breaking off chunks of the reef and digest the algae that grows within, or they feed directly on algae (Ref. 28023).

Estimates based on models

Preferred temperature (Ref. 123201): 22.3 - 29.1, mean 26.2 °C (based on 211 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.6250 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01122 (0.00535 - 0.02352), b=3.09 (2.92 - 3.26), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Nivel trófico (Ref. 69278): 2.0 ±0.00 se; based on food items.

Resiliencia (Ref. 120179): Alto, población duplicada en un tiempo mínimo inferior a 15 meses (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (22 of 100).

Price category (Ref. 80766): High.

Nutrients (Ref. 124155): Calcium = 62.1 [37.1, 120.0] mg/100g; Iron = 0.764 [0.411, 1.300] mg/100g; Protein = 18.6 [16.6, 20.5] %; Omega3 = 0.0961 [, ] g/100g; Selenium = 25.9 [14.9, 49.0] μg/100g; VitaminA = 52.8 [15.9, 176.3] μg/100g; Zinc = 1.83 [1.25, 2.91] mg/100g (wet weight);
