Excess heat is also released in areas where fur is absent or blood vessels are close to the skin e.g. the muzzle, nose, ears, footpads, inner thighs, and shoulders. On days when they are not swimming to cool down but to hunt, and the water is freezing, a thick layer of blubber keeps them warm, their hair is also designed so that water is easily shaken off as well as any ice that may start to form. The hair sticks together when wet and effectively keeps the bear dry when it is swimming. The hairs are hollow and channel ultraviolet light down to the bear's skin, which is black. https://www.nutramozo.com/pcpac
