Polar Bear
(Ursus maritimus)


    Polar Bears can be found in the northern areas of
    Canada, Alaska, Russia and Norway.  They are also
    located in various parts of Greenland.


    Polar Bears' diets consist mainly of seals.  Polar Bears
    will use a variety of tactics while hunting seals, and these
    tactics will usually involve stealth and patience.  Polar
    Bears will occasionally feed on other animals including
    walruses.  Polar Bears will also sometimes feed on the
    carcases of dead whales.  


    Polar Bears are often located near areas of water and ice
    floes where their favorite food - seals - can be found.  
    Polar Bears have dens in which they will sleep and where
    the females will give birth to cubs.  Polar Bears do not
    enter true hibernation in the winter as this is a period of
    hunting, however, some Polar Bears and pregnant
    females in particular will enter a deep sleep where their
    heart rates will drop.    

Size and Description

    Polar Bears are among the largest land mammals on
    earth.  Males can weigh between 700 - 1400 pounds and
    stand between 8 - 10 feet tall.  Females are smaller than
    males, with weights averaging 350 - 700 pounds.  Polar
    Bears appear to have a white coat; however, the actual
    hairs are translucent and clear.  The skin of the Polar
    Bear is black.  The coat and skin are adapted to absorb
    sunlight and retain heat.  Like many animals of the
    tundra, Polar Bears have short ears to minimize heat


    Polar Bears will give birth one out of every two to three
    years.  The mating season occurs in the spring, and the
    female will then give birth in the winter to a litter of one to
    two cubs.  


    Polar Bears are listed as vulnerable because of the
    possibility of ice floes in the arctic region melting due to
    climate change.  While the number of Polar Bears is still
    relatively healthy, human activity such as pollution and oil
    drilling could create habitat loss for the bear.
