Biology     Glossary (e.g. epibenthic)

Inhabits inner reef flats and sheltered lagoons. A common inshore species, often on algal or silty reefs and among attached Sargassum on shallow rubble flats (Ref. 48637). Solitary or in groups (Ref. 90102). Feeds mainly on filamentous green algae and to a lesser extent on fleshy and coralline red algae and on benthic invertebrates. Monogamous (Ref. 52884).

Estimates based on models

Preferred temperature (Ref. 123201): 25.1 - 29.3, mean 28.4 °C (based on 2768 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.03631 (0.01554 - 0.08482), b=2.88 (2.69 - 3.07), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).
Trophic level (Ref. 69278):  2.5   ±0.20 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 (10 of 100).
Nutrients (Ref. 124155):  Calcium = 134 [60, 335] mg/100g; Iron = 1.16 [0.54, 2.69] mg/100g; Protein = 17.9 [15.6, 20.1] %; Omega3 = 0.11 [0.05, 0.23] g/100g; Selenium = 32.3 [14.8, 75.5] μg/100g; VitaminA = 46.7 [12.0, 192.6] μg/100g; Zinc = 2.2 [1.4, 3.5] mg/100g (wet weight);
