Biologia     Glossario (es. 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. 115969): 25.1 - 29.3, mean 28.4 (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.
Resilienza (Ref. 120179):  Alto, tempo minimo di raddoppiamento della popolazione meno di 15 mesi (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
