Polar bears have thick water-repellant fur to insulate them against the frigid Arctic temperatures and to keep them dry while swimming or moving through icy waters. The fur consists of two layers: a dense undercoat for insulation and longer guard hairs that repel water and snow. This unique adaptation helps polar bears maintain their body heat and stay buoyant in their icy habitat, enhancing their survival in extreme conditions.
