Who have more hair a polar bears or a black bear?

Polar bears generally have less dense fur compared to black bears, as their fur is designed for insulation in icy environments rather than for protection. Polar bears have a thick layer of blubber beneath their skin to help keep them warm. In contrast, black bears have denser fur that provides better insulation in forested habitats. Therefore, while both bears have adaptations suited to their environments, black bears typically have more hair overall.
