| | | | | | | Loc: | | | Bering Sea, S Aleutian Basin, off S Aleutian Is., Kamchatka, off E Japan, Station Knot, off British Columbia, off California, Antarct. (Pacif., Atlant., E Indian), Sub-Antarct. (Drake Passage), Sargasso Sea (off E Cape Cod) | | | | N: | 10 | | | | Lg.: | | | (22) F: 8,5-8; M: 9-8; {F: 8,00-8,50; M: 8,00-9,00} | | | | Rem.: | bathypélagique.
Cette espèce paraît bipolaire.
Sa présence dans la Mer des Sargasses est étonnante et ne s'explique que par les courants profonds polaires.
