Polar bears are sea mammals, having very thick fur enabling them to dwell in icy regions. In addition to thick fur they also have a layer of blubber beneath the fur for providing insulation. They have also large and flat front feet, which are making them excellent swimmers.
Polar bears are together with the Kodiak bears the largest land carnivores in the world. Their shoulder height is more than 1.6 m (5.2 ft) and a total length of up to 3.05 m (10.0 ft). The heaviest polar bear weight recorded was 1,003 kg (2,210 lb). They mainly feed from seals living in icy areas.
