Biology     Glossary (e.g. epibenthic)

Adults occur in exposed seaward reefs, on relatively barren gently sloping terraces with scattered low-profile corals. Feed on zooplankton found 1 to 2 meters above the substrate (Ref. 7247). 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. 52881).

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5625   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01479 (0.00642 - 0.03409), b=3.00 (2.80 - 3.20), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.4   ±0.45 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 = 196 [111, 430] mg/100g; Iron = 1.2 [0.7, 2.0] mg/100g; Protein = 18.5 [17.4, 19.6] %; Omega3 = 0.183 [0.097, 0.342] g/100g; Selenium = 21 [10, 44] μg/100g; VitaminA = 285 [96, 822] μg/100g; Zinc = 2.37 [1.53, 3.45] mg/100g (wet weight);
