What are some Polar bear fun and interesting facts?

Polar bears are the largest land carnivores, with adult males weighing between 900 to 1,600 pounds. They have a thick layer of blubber and a dense, water-repellent coat that helps them survive in frigid Arctic temperatures. Interestingly, polar bears are classified as marine mammals because they spend much of their time on sea ice and are Excellent swimmers, capable of covering long distances in open water. Additionally, their skin is black beneath their white fur, which helps absorb sunlight and keep them warm.
