Eastern Atlantic: Norway to South Africa (Ref. 6633), including the Mediterranean, Canary Islands, Madeira, Cape Verde, and Tristan da Cunha. Western Atlantic: Newfoundland, Canada and Gulf of Maine to North Carolina, USA (Ref. 7251). Recorded from Uruguay to Argentina (Ref. 9050). Western Indian Ocean: St. Paul and Amsterdam islands (Ref. 6633). Southwest Pacific: New Zealand (Ref. 5755, 9072).

Biology     Glossary (e.g. epibenthic)

Adults prefer to inhabit caves and shipwrecks (Ref. 27121). Juveniles congregate below floating objects (Ref. 27121). Usually solitary. Feed on large crustaceans, cephalopods and benthic fishes (Ref. 27121). Spawn in the summer (Ref. 35388). Are primary gonochorists (Ref. 58421). Marketed fresh or frozen; eaten steamed, fried, broiled, boiled, microwaved and baked (Ref. 9988). Minimum depth reported from Ref. 6633.

Estimates of some properties based on empirical models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.8125   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01450 (0.01071 - 0.01964), b=3.03 (2.94 - 3.12), based on LWR estimates for this species (Ref. 93245).
Trophic Level (Ref. 69278):  4.1   ±0.64 se; Based on food items.
Resilience (Ref. 69278):  Low, minimum population doubling time 4.5 - 14 years (K=0.05-0.08; tmax=76; tm=9-10 yrs estimated from VBGF; Fec=3 million).
Vulnerability (Ref. 59153):  Very high vulnerability (76 of 100) .
Price category (Ref. 80766):   Low.
