Snowy Snuggles

source:clickhereIn Canada's Wapusk National Park, a mother polar bear cuddles with her two cubs. When polar bears are born, they weigh only a pound. They'll stay with their mother in a hibernation den until they reach 20-30 pounds, at which point they all venture out into the world. Female polar bears have about five litters over the course of their lives, a significantly lower reproduction rate than other mammals.
