Biology     Glossary (e.g. epibenthic)

Adults occur in inshore and offshore rocky reefs in 5 to 30 meters in small to large aggregations (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).

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01259 (0.00571 - 0.02773), b=3.03 (2.84 - 3.22), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.0   ±0.1 se; based on size and trophs of closest relatives
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 = 60.3 [26.7, 115.3] mg/100g; Iron = 0.85 [0.49, 1.42] mg/100g; Protein = 19.4 [18.3, 20.4] %; Omega3 = 0.224 [0.126, 0.388] g/100g; Selenium = 10.8 [5.4, 22.6] μg/100g; VitaminA = 111 [37, 329] μg/100g; Zinc = 1.08 [0.69, 1.62] mg/100g (wet weight);
