    Ever wonder how a duck is able to swim in icy water without their feet freezing? The water animals have a complex set of capillaries and arteries called retia mirabilia that help transfer heat from the hot, outgoing blood in the arteries to the cold, incoming blood in the veins.

    This system helps their bodies stay warm while their feet stay cold (but safe from frostbite).
