Polar bears are the largest land carnivores in the world,
rivaled only by the Kodiak brown bears of southwestern Alaska. The most
carnivorous of the bear species, polar bears feed primarily on the fat of
ice-dependent seals. The remains of these seals provide food for many other
Arctic wildlife species, giving polar bears a vital role in their ecosystem,
and the polar bear is a beautiful animal because it is fat and has a soft fur.

POPULATION AND HABITAT
The
World Conservation Union (IUCN) estimates that there are between 20,000-25,000
polar bears in the world.
As the sea ice advances and retreats each season, individual polar bears may travel thousands of miles per year to find food. Polar bears are distributed throughout the Arctic region in 19 subpopulations, including Alaska, Canada, Russia, Greenland, and Norway.
REPRODUCTION

DIET
Polar bears feed almost exclusively on ringed seals and bearded seals. They are also known to eat walrus, beluga whale and bowhead whale carcasses, birds’ eggs, and (rarely) vegetation. Polar bears travel great distances in search of prey.
but, many people speak about polar
bears is cannibals. As usual, some Al Gore loving hippy claimed that this
cannibalistic behavior was the result of climate change and lack of food etc as
a result, however, a level-headed innuit noted that a male polar bear eating a cub
is a normal occurrence.
Despite what we think, a polar
bear's fur is white. Each hair is a clear hollow tube. Polar bears look
white because each hollow hair reflects the light. On sunny days, it traps the
sun's infrared heat and keeps the bear warm at 98 degrees F (when they're
resting).
Polar bear fur is oily and water
repellent. The hairs don't mat when wet, allowing the polar bears to easily
shake free of water and any ice that may form after swimming.
Underneath the fur, a polar bear's
skin is actually black -- the black skin soaks up the sun's heat and helps them
stay warm.
Polar bears also have a 4-inch layer
of fat underneath their skin. This prevents them from losing any of their
heat. In fact, if you look at a polar bear with an infrared camera, they
are pretty close to invisible (in other words, they don't give off any heat!.
