Biology     Glossary (e.g. epibenthic)

Lives in coastal waters at shallow depths, generally from 10-20 m, more seldom from 75-100 m, on rocky bottom with seaweeds. Solitary and secretive, undertakes only limited local movements. Spawns from May to September at 50-70 m depth near the shore throughout its entire range. Feeds on sea stars, crustaceans, worms, mollusks and small fish (Ref. 1371).

Estimates based on models

Preferred temperature (Ref. 123201): 8.5 - 12.5, mean 10.4 °C (based on 120 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 1.0000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01072 (0.00412 - 0.02789), b=3.06 (2.83 - 3.29), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.8   ±0.56 se; based on food items.
Fishing Vulnerability (Ref. 59153):  Low vulnerability (20 of 100).
Nutrients (Ref. 124155):  Calcium = 28.6 [14.3, 51.4] mg/100g; Iron = 0.331 [0.207, 0.536] mg/100g; Protein = 18.4 [17.1, 19.6] %; Omega3 = 0.565 [0.290, 1.051] g/100g; Selenium = 13.7 [7.3, 26.5] μg/100g; VitaminA = 10.4 [3.7, 28.5] μg/100g; Zinc = 0.565 [0.427, 0.763] mg/100g (wet weight);
