The polar bear is one of the largest animals in the world. Although they look white, their fur is actually clear, hollow hairs that trap air next to its body which helps to keep it warm. Their skin is actually black which allows them to absorb the heat from the sun. They have a thick layer of blubber which helps them to keep warm even when swimming in the icy water.
Their favourite food is ringed seal, but they have to wait very patiently at their breathing holes in the ice in order to catch them when they pop up to get a breath of air or catch them in their winter dens.
Polar bears are protected because at one time they were a popular target of sport hunting and became endangered.
