The species of bear known for its white fur is the polar bear, scientifically named Ursus maritimus. Polar bears are primarily found in the Arctic region and are uniquely adapted to their cold environment, possessing a thick layer of blubber and a dense fur coat that insulates them from frigid temperatures. Their white fur not only provides camouflage against the snow and ice but also helps them attract heat from sunlight. As apex predators, polar bears primarily hunt seals and have an excellent sense of smell, allowing them to detect prey from great distances, making them a vital part of their ecosystem.
