Worldwide except in tropical waters (Ref. 27363). North Atlantic: Gulf of Mexico and Cape Blanc, Mauritania north to Davis Strait, Canada and Iceland. South Atlantic: off South Africa. Southeast Pacific: off Chile. Eastern Indian Ocean: Australia (Ref. 7300). Southwest Pacific: New Zealand (Ref. 5755).

Biology     Glossary (e.g. epibenthic)

Benthopelagic (Ref. 58302) and epibenthic (Ref. 58426). Not uncommon in depths around 180 m off Iceland and Greenland. Individuals with nearly ripe eggs have been found in late autumn off Iceland. Mostly found at depths well below 200 m, but enters slightly shallower water on Grand Banks in Canada (Ref. 7251). Feeds primarily on sea anemones (Ref. 4449).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5161   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00191 (0.00103 - 0.00352), b=3.07 (2.89 - 3.25), based on LWR estimates for species & (Sub)Family-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  3.5   ±0.37 se; Based on food items.
Resilience (Ref. 69278):  Low, minimum population doubling time 4.5 - 14 years (Assuming tmax>10).
Vulnerability (Ref. 59153):  High vulnerability (63 of 100) .
Price category (Ref. 80766):   Unknown.
