Comments: Adults prefer deep waters but females and occasionally males may be found on the surface.  Depth of distribution in January and February is 150-250 m; 100-120 m in March and April.  Adults feed mainly on the amphipod <i>Macrohectopus branickii</i>.  Mature individuals spawn in July to October.  Fat content of the body is about 25%.  The dead fish does not sink but float up to the surface and freeze into ice.  In spring, they are cast ashore by the waves (Ref. 26334).
