Description:
The Polar Bear is made for life in the Arctic. Males are huge, hulking
predators that can weigh up to 1,700 pounds and reach 10 feet in
length. Polar Bear are incredible swimmers and have no problem swimming
the Arctic waters for miles at a time. Polar Bears use their front
paws to paddle and their back paws to steer while in the water.
They are also fast runners and can reach speeds in excess of 25
miles per hour. Scientists estimate the world population of Polar
Bears at about 25,000.
The
Polar Bear is well camouflaged in its Arctic habitat. It is entirely
white or slightly off-white with black eyes, a black tongue, and
a conspicuous black nose. The head is small and the tail is barely
noticeable. Polar Bears have an excellent sense of smell and can
detect seals from long distances. Polar Bears have thick, woolly
fur close to the skin to keep it warm, and hollow outer hairs that
keep water away from the skin. Like most Arctic animals, the Polar
Bear has a thick layer of fat that helps to keep it warm in sub-freezing
temperatures.
Habitat/Range:
The Polar Bear is found primarily north of the Arctic Circle, in
the frozen lands and ocean of Alaska, northern Canada, Greenland
and Eurasia. In Canada, Polar Bears may congregate at coastal spots
along the Hudson Bay. At Churchill, Manitoba, tour buses take people
to the shores of the bay to view wild Polar Bears.
Diet:
Polar Bears are powerful and fearless Arctic predators. They feed
primarily on seals and young walruses. Polar Bear hunting techniques
are legendary. They often times wait hours at breathing holes carved
by seals. When a seal comes to the surface for oxygen, the bear
seizes it by the head in its jaws and drags it out of the water.
Polar Bears may stalk their prey for hours before striking. Sometimes,
Polar Bears will take a baby walrus from a colony of hundreds, despite
the slashing tusks of the adults. Polar Bear leftovers are eaten
by other Polar Bears, Ravens and Arctic Foxes.
Young/Reproduction:
Female Polar Bears give birth to twin cubs every year. The cubs
weigh less than one pound at birth. Cubs drink their mother's mile
for 15-18 months. Female Polar Bears are very protective of their
young and may attack any threat. Nevertheless, 60 percent of Polar
Bear cubs die in their first year of life.
