  • animals that live in polar regions of the world are mainly protected from the cold by a thick layer of fat called blubber but the blubber alone would not do the trick so they develop a thick coarse layer of fur close to the skin with longer hollow hairs away from the skin the hollow hairs help to retain the animals body heat even if they are submerged in icy cold water as with polar bears , animals that spend the majority of their time submerged in the cold water ( walrus seals whales ect. ) forgo the hairs and depend solely on their blubber therefor they have more of it.
  • Some animals, for example teleost fishes (like the rock cod Pagothenia borchgrevinki) and some insect species, produce proteins which act as natural antifreezes and metabolic enzymes which actually function best at very low temperatures. See, for example, the specialist book on fish antifreeze proteins by Kathryn Ewart at http://www.worldscibooks.com/lifesci/4917.html.

  • Some actually have a biological form of anti-freeze in their blood.

  • It's their natural habitat. Nature designed them that way.
