Figure 5 The temperature at different sites within and outside the fur of a mammal adapted to arctic life. The temperature at the surface of the epidermis is close to that of deeper tissues below the dermis, i.e. is close to what is called the core temperature. The close match between these measurements shows that nearly all the insulation is provided by fur, notably by the air trapped between the hairs
