Spotty records from the subarctic and subantarctic to temperate waters of the Atlantic Ocean. South Atlantic: along the coast of Africa, on Walvis Ridge, near Discovery and Meteor seamounts and on the continental slope of Antarctica (Ref. 44938). Northwest Atlantic: Canada (Ref. 5951). North Pacific: northwestern Bering Sea and the Pacific Ocean south of the Gulf of Alaska to California and to Japan and the Sea of Okhotsk.

Biology     Glossary (e.g. epibenthic)

Epibenthic (Ref. 58426). Food consists of free-living small animals, such as crustaceans and squids. This species is reportedly being caught by trawl in temperate waters of Australia (Ref. 9563).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 1.0000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00363 (0.00180 - 0.00731), b=3.12 (2.94 - 3.30), based on LWR estimates for this (Sub)Family-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  3.4   ±0.47 se; Based on food items.
Resilience (Ref. 69278):  Low, minimum population doubling time 4.5 - 14 years (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153):  Moderate to high vulnerability (45 of 100) .
Price category (Ref. 80766):   Medium.
