Biologia     Glossario (es. epibenthic)

Occur on rock bottoms; near shore, outside kelp beds and along drop-offs (Ref. 2850). Large specimens usually found deeper than 30 m, small ones over sand and in kelp beds mostly from 12-21 m (Ref. 2850). Aggregate for spawning in summer (Ref. 2850). Pelagic spawners (Ref. 56049). Longevity of 90 to 100 years (Ref. 56049) stemmed from speculation on the age of a 557 lb fish caught in 1962, but the oldest age determined from otoliths of a 435 lb fish was 72 to75 years (Ref. 4563). Validated age so far is up to >50 years using bomb radiocarbon (A.H. Andrews, pers. comm.)

Estimates of some properties based on models

Preferred temperature (Ref. 115969): 14.8 - 23, mean 20.9 (based on 48 cells).
Phylogenetic diversity index (Ref. 82805):  PD50 = 0.8125   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01479 (0.00752 - 0.02911), b=3.03 (2.85 - 3.21), in cm Total Length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).
Trophic Level (Ref. 69278):  4.5   ±0.80 se; Based on food items.
Resilienza (Ref. 69278):  Molto basso, tempo minimo di raddoppiamento della popolazione più di 14 anni (tm=11; tmax=75; also Musick et al. 2000 (Ref. 36717)).
