Biology     Glossary (e.g. epibenthic)

Inhabits coral and rocky reefs and grass bed areas to depths of about 30 m (Ref. 9710). Occurs singly or in small groups (Ref. 9710). Feeds mainly on marine angiosperms and epiphytic algae. Caught mainly with traps, nets and other types of artisanal gear.

Estimates based on models

Preferred temperature (Ref. 123201): 24.8 - 29.2, mean 27.5 °C (based on 233 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5312   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.02089 (0.00803 - 0.05439), b=2.98 (2.75 - 3.21), 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):  High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (16 of 100).
Price category (Ref. 80766):   High.
Nutrients (Ref. 124155):  Calcium = 52.4 [20.4, 149.7] mg/100g; Iron = 0.709 [0.277, 1.756] mg/100g; Protein = 18 [16, 20] %; Omega3 = 0.066 [0.029, 0.146] g/100g; Selenium = 13.2 [4.0, 39.6] μg/100g; VitaminA = 42.1 [9.8, 167.6] μg/100g; Zinc = 2.25 [1.06, 4.02] mg/100g (wet weight);
