polar bears are my favourite bears

i like the fact that they are solitary and they can eat all kinds of big animals and they can swim well

Is that bear dancing in front of a mirror?

10-03-2005, 16:41:51
yeah they put them up there to make the arctic look bigger, really it's only about a mile square

And there's only one polar bear in the whole of the artic? :hmm:

I find that very hard to believe Mr Ghidra.

maybe a small wager? :cute:

Could they eat an elephant?

in instalments yes

after all they eat some small whales

Despite what our eyes tell us, a polar bear's fur is not white. Each hair shaft is pigment-free and transparent with a hollow core.

Polar bears look white because the hollow core scatters and reflects visible light, much like ice and snow does.

When photographed with film sensitive to ultraviolet light, polar bears appear black.

Early speculation over this discrepancy produced a theory, now widely repeated as fact, that polar bear hair acts like a fiber optic guide to conduct ultraviolet light to the skin.
In 1998, Daniel W. Koon, a physicist at St. Lawrence University in Canton, New York, decided to actually test whether or not polar bear hair could efficiently conduct ultraviolet light.
Koon and a graduate assistant, Reid Hutchins, obtained polar bear hair from the Seneca Park Zoo in Rochester. Their experiments showed that a one-fifth inch strand of polar bear hair was able to conduct less than a thousandth of a percent of the applied ultraviolet light. With such a high loss rate, meaningful amounts of ultraviolet light cannot be reaching a polar bear's skin.
Instead, Koon believes the ultraviolet light is absorbed by the keratin making up the hair.

In 1979, three polar bears at the San Diego Zoo turned green. Scientists discovered that colonies of algae were growing in the bears' hollow hair shafts.

Although the algae in no way harmed the animals, zoo veterinarian Phillip Robinson restored the bears' white fur by killing the algae with a salt solution.

The fur on a polar bear cub is whiter than that of adult bears. In older bears, fur colors range from white to almost yellow.

Hybrid cubs born to captive polar bears and their close relative, the brown bear, are white at birth but later turn blue-brown or yellow-white.

A polar bear is so well-insulated that it experiences almost no heat loss. In addition to its insulating fur, the bear's blubber layer can measure 4.5 inches thick.

So effective is the polar bear's insulation that adult males quickly overheat when they run.

Because polar bears give off no detectable heat, they do not show up in infrared photographs. (Infrared film measures heat.) When a scientist attempted to photograph a bear with such film, he produced a print with a single spot--the puff of air caused by the animal's breath.

If I could be any bear it would be a green polar bear

The hollow center of the hair should add significantly to their insulation.
