The polar bear is the most carnivorous member of the bear family, and throughout most of its range, its diet primarily consists of ringed ("Pusa hispida") and bearded seals ("Erignathus barbatus"). The Arctic is home to millions of seals, which become prey when they surface in holes in the ice in order to breathe, or when they haul out on the ice to rest. Polar bears hunt primarily at the interface between ice, water, and air; they only rarely catch seals on land or in open water.
