Habitat Type: Marine
Comments: Cold temperate to arctic marine waters, often in water 1000 m or more in depth; ice edges and broken pack ice (Leatherwood and Reeves 1983). Cold, deep water along and seaward of the edge of the continental shelf (Reeves and Mitchell 1993, Reeves et al. 1993). Sometimes penetrates up to several miles into ice-covered areas but more frequently occurs in open ocean. Young are born in the water.
