Polar bear (Ursus maritimus) grows up to 2.6 m and can be simply recognized by a thick white fur. Together with Kodiak bear, the polar bear is the largest land carnivore (order Carnivora). Polar bears are widespread in the whole Arctic region. They prefer floating pack ice which they use for traveling. Thus, their geographic range usually reaches the southern area of floating ice.
