Toothless and blind, they rely on their mother for nutrient milk and warmth.
While their white fur keeps them camouflaged against the snow, their black skin absorbs the heat of sunlight that may pass through their coat.
A layer of fat beneath the skin insulates their body further from sub-zero temperatures.
Polar bears, also called sea bears or ice bears, are found throughout the Arctic; mainly in Canada, Norway, Alaska, Greenland and Russia.
They are solitary animals and highly evolved for living in frigid arctic temperatures.
