Here's why:
* Thick Fur: Polar bears have a dense, insulating layer of fur that keeps them warm in the frigid Arctic. This fur is so effective that it can even trap heat from the sun, allowing them to survive in areas with little sunlight.
* Blubber: Underneath their fur, polar bears have a thick layer of blubber, a type of fat, which acts as an additional layer of insulation and protects them from the cold water.
* Color Camouflage: Their white fur provides excellent camouflage in the snowy environment, helping them hunt seals and avoid predators.
While other animals have adaptations that help them survive in various environments, the combination of fur, blubber, and camouflage makes the polar bear particularly well-suited for a wide range of cold climates.
