Habitat Type: Marine
Comments: Bays, fiords, and inlets in warmer months; moves south into deeper water when ice begins to form. Not often far from loose pack ice. Near northern Baffin Island in summer, made both shallow dives and deep (to 257 m) dives to bottom (Martin et al., 1994, Can. J. Zool. 72:118-125). Probably dive to depths of more than 1000 meters (Reeves, in Wilson and Ruff 1999).
