The coat can vary from pure white to creamy yellow to light brown, depending upon season and angle of light. A polar bear's black skin absorbs heat from the sun, helping it stay warm. Polar bears are strong swimmers, paddling dog-style with their front paws while holding their hind feet and legs flat like rudders. Polar bear cubs are born in a den from November through January. They are born helpless with their eyes closed, and appear hairless because of their very fine fur.
Cubs open their eyes within the first month, and begin walking at two months.
Cubs emerge from the den when they are four to six months old. Polar bears at zoological parks provide opportunities for the public to learn about these animals and how human activities may impact their survival. Scientists and specialists study polar bear biology, including polar bear reproduction, birth and care of young, and communication. Inc. Busch Entertainment Corporation. All rights reserved.
