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.
Skin. Polar bears have black skin under which there is a layer of fat that can measure up to 4.5 inches (11.5 centimeters) thick. 1  On land (or on top of the sea ice) the polar bear's thick fur coatâ not its fatâprevents nearly any heat loss.2  In fact, adult males can quickly overheat when they run.olar bears' fur consists of a dense, insulating underfur topped by guard hairs of various lengths. It is not actually whiteâit just looks that way. Each hair shaft is pigment-free and transparent with a hollow core that scatters and reflects visible light, much like what happens with ice and snow.
