The majority of records are from the Atlantic, possible because more deep sampling has been carried out there, other than the hadal sampling carried out by the Vityaz (e.g. Rudjakov, 1962). It extends as far south as the Polar Front in the Southern Hemisphere, and may be an indicator of the spread of North Atlantic Deep Water. A subspecies has been described from the North Pacific at great depths in the vicinity of the Kuril-Kamchatka Trench that may well prove to be a different species.   n Mean mm s.d.
