Generally associated with ice, but they have been swimming at sea many kilometers away from the nearest land. Feeds on ringed, bearded, harp and hooded seals, and rarely walruses and white whales; sometimes eat arctic cod and other forms of animal and vegetable matter (Ref. 1394). Generally associated with ice, but they have been swimming at sea many kilometers away from the nearest land. Feeds on ringed, bearded, harp and hooded seals, and rarely walruses and white whales; sometimes eat arctic cod (Ref. 1394), charr, sculpin, and plants (Ref. 81152). They display migration patterns and spend time on the ice for hunting, a positive energy state, and move to their terrestrial habitat, a negative energy state, when the ice melts. Earlier ice break-ups show earlier arrival of polar bears ashore (Ref. 93189).
