Biology     Glossary (e.g. epibenthic)

Inhabits offshore waters over soft bottoms, often with boulders, from 25-590 m, but most common from 100-400 m (Ref. 4694). Benthic (Ref. 58426). Feeds mainly on echinoderms, but also crustaceans, mollusks, fishes (Ref. 4694) and worms (Ref. 58426). In Barents sea, it reached at least 80 cm, age 9 years. Marketed fresh or as frozen fillets. Leather can be made of the skin (Ref. 35388).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5938   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00331 (0.00177 - 0.00620), b=3.21 (3.04 - 3.38), based on LWR estimates for species & Subfamily-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  3.5   ±0.4 se; Based on diet studies.
Resilience (Ref. 69278):  Low, minimum population doubling time 4.5 - 14 years (K=0.06-0.13; tm=8; Fec=4,200-35,200).
Vulnerability (Ref. 59153):  Very high vulnerability (80 of 100) .
Price category (Ref. 80766):   Low.
