In springtime, a mother polar bear emerges from her den with her newborn cub or cubs. She and her cubs will stay at their den for a few days or weeks, giving the cubs a chance to play, explore, and strengthen their legs. Once polar bear cubs are big enough, she and her cubs will head out onto the sea ice. A mother polar bear will begin teaching her young cubs not only how to hunt, but how to simply survive in the Arctic. | Polar Bears International
