After the mother polar bear searches, the baby bears will freeze at a motion-less position in order to not frighten off any potential prey the mother bear might be hunting. Should the baby bears move, the mother bear will subject them with a quick slap to the head. The baby bears usually get the message pretty quick then.
Only the pregnant female bears hibernate. Though hibernating females sleep soundly, they are quickly and easily woken. The female bear’s heart rate will slow down to as little as 27 beats per minute from her usual rate of approximately 46 beats per minute. Most bears hibernate, however polar bears are the only bears that could give birth while hibernating.

Their hair is also oily which allows them to shake of excess water after swimming.
All polar bears have padded paws with rough surfaces in their base. The rough surface of the pads help the bears to walk on snow and ice without slipping over. Their broad paws are also helpful for swimming. Their front paws are used to propel them through the water while the back legs and paws are utilized to steer. Another use they make of their paws is to pay their muzzle (nose) when resting in order to conserve body heat. Their legs and paws are so strong they can kill prey with a single blow.
