Do polor bears have clean skin?

Polar bears have clean skin under their thick fur, which helps insulate them from the cold. Their fur is water-repellent and helps keep them dry, but it can become dirty from their environment or when they hunt. Despite this, the skin itself is typically free of external contaminants, as the fur protects it from direct exposure to dirt and bacteria. Overall, while their fur may not always look clean, their skin remains relatively uncontaminated.
