Biology     Glossary (e.g. epibenthic)

Adults are found in 1-6 m (Ref. 7247) and in coastal to outer reef crests to depths of about 20 m (Ref. 48636). They occur solitarily or in groups in reef margins and upper seaward slopes subject to mild surge (Ref. 9710). Feed mainly on algae. 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). Diurnal species (Ref. 113699).

Estimates based on models

Preferred temperature (Ref. 123201): 25.4 - 29.3, mean 28.6 °C (based on 2013 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01479 (0.00651 - 0.03363), b=3.00 (2.81 - 3.19), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  2.5   ±0.2 se; based on diet studies.
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).
Price category (Ref. 80766):   Unknown.
Nutrients (Ref. 124155):  Calcium = 168 [92, 298] mg/100g; Iron = 1 [1, 2] mg/100g; Protein = 18.5 [17.4, 19.5] %; Omega3 = 0.151 [0.090, 0.246] g/100g; Selenium = 21.4 [12.0, 39.8] μg/100g; VitaminA = 134 [44, 414] μg/100g; Zinc = 2.57 [1.74, 3.60] mg/100g (wet weight);
