Today, February 27th, we are celebrating the world’s largest carnivore. Polar Bears live along the shores and on sea ice in the cold Arctic. When the sea ice forms over the ocean in cold weather many polar bears, except pregnant females, head out onto the ice to hunt seals. Polar bears have been spotted hundreds of miles away from shore. When the warm weather causes the ice to melt polar bears move back toward the shore. In the fall pregnant polar bears make dens in snowbanks, where they will stay throughout the winter and give birth to one to 3 cubs. Generally she nurses them for two and half years. A polar bear paws have rough pads that prevent them from slipping on the ice. They use their large front paws to swim and their back legs to steer through the icy waters. Some polar bears have been known to swim 100 miles at a stretch. Adult males usually weight between 720-1700 pounds. Adult females usually weigh 500-600 pounds. Males can grow 10 feet tall, making them the largest of all bears.
