Information


    Located

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

    Diet

    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.  

    Habitat

    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 loss.     

    Reproduction

    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.  
Notes

  • 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.
