Polar bears have four large paws, that can be 30cm (12) across. Imagine having feet that were as large as dinner plates! Their giant paws act like snowshoes to spread the polar bear's weight out so they can walk on thin ice. A polar bear has five toes on each foot, and there is a sharp claw at the end of each toe.
Arctic Adaptations. Polar bears live in one of the planet's coldest environments and depend on a thick coat of insulated fur, which covers a warming layer of fat. Fur even grows on the bottom of their paws, which protects against cold surfaces and provides a good grip on ice. The bear's stark white coat provides camouflage in surrounding snow and ice. But under their fur, polar bears have black skinâthe better to soak in the sun's warming rays. Hunting.
