Polar bears are not only the largest of the world’s eight living bear species but also the most aquatic. Their scientific name, Ursus maritimus, translates to “sea bear,” and they are officially classified as marine mammals. Polar bears spend their lives in and around the ocean, and as such, they are great swimmers. Read on to find out how fast polar bears can swim, along with other water and land speed stats.
