Polar bears live on the shores of the Arctic Ocean and can
be found in Alaska, Canada, Russia, Denmark (Greenland)
and Norway.
Polar
bears have partially webbed feet and are able to swim six
miles per hour for up to 60 miles without stopping.
No
other four-footed animal can swim as fast as a polar bear.
Polar
bears sometimes slide down slopes on their bellies.
A
fully grown polar bear's worst enemy is the killer whale.
A
polar bear's fur is not white. It is actually transparent.
Each hair shaft is pigment free and transparent with a hallow
core. Polar bears look white because the hallow core reflects
visible light, same as snow and ice does. Their fur coloring
is a great camouflage.
Polar
bears are the largest land predators hunting mainly seal
in the Arctic.
Polar
bears are considered better hunters than any other kind
of bear.
Polar
bears primarily eat seals. Polar bears rest patiently at
a seal’s breathing hole in the ice, waiting for a
seal in the water to surface. Once the seal comes up, the
bear will spring and sink its jagged teeth into the seal’s
head.
Male
Polar bears weigh up to 770 to 1,500 pounds and are 8 to
10 feet tall. Females weigh from 330 to 660 pounds and are
6 to 7 feet tall.
Unlike
brown and black bears, polar bears, except for pregnant
females, spend their winters hunting for seals.
Polar
Bears make a den only if the weather is worse than usual.
A
female Polar bear gives birth to one to three cubs in December
and January in a den which is dug in snow and ice.
Polar
bears are as intelligent as apes. They are highly cognitive
creatures.
The
Polar bears only enemies are human hunters and sometimes
other bears. An adult Polar bear's mortality is very low,
only 5% per year.
The
U.S., Canada, Denmark, Norway, and the Soviet Union signed
an agreement in 1973 to protect polar bears. Each of these
countries either banned hunting or established rules for
how many polar bears could be hunted within its own boundaries.
These rules help keep polar bear populations stable. Today,
25,000 to 40,000 polar bears roam the Arctic.
Adult
Polar bears can live up to 20 years in the wild and may
live up to 40 years in captivity.
