        Eating for survival


        These arctic giants rely on the best-possible diet to help see
        them through such extreme conditions
        Polar bears need to maintain their thermal fat layer to
        battle the cold, and seal blubber contains 70 per-cent
        energy-packed fat, rich in healthy oils and vitamins.
        Seals are abundant in the Arctic circle so they are a
        logical choice, and with 42 sharp teeth the polar bear
        has little trouble killing a meal. The hunting skills of
        polar bears range from a silent sneak attack to an
        outright charge, so no seal is safe.
