Polar Bears, Polar Lives

Polar bears are bears that live in the North Pole. They have the same characteristics as brown or black bears but they don’t hibernate. Beacause they live in the cold, they are used to it, so in winter, they don’t need to hibernate. Only pregnant polar bears do, to keep warm. Brown, black and other kinds of bears do have to hibernate because their bodies are not made for the intense cold that winter has! http://www.futurity.org/polar-bears-survive-arctics-icy-blasts/
