6″ & 4″ Cloth National Wildlife Federation Polar Bears. I received the bears as a gift after a donation to the Federation in 2009 and received the following fact sheet:” About the polar bear… 1. Of all living bear species, polar bears are the largest, averaging eight feet in height and weighing between 440 and 1,700 pounds. 2. Polar bears inhabits Arctic sea ice, water, islands and northern limits of the continental coastlines of the Northern Hemisphere. 3. Black skin protected by a dense coat of underfur, covered by a coat of longer guard hairs, allows the polar bear to survive harsh Arctic conditions where temperature drop to well below freezing. 4. Polar bears can live as long as 30 years, but only a small number live beyond 20 years.”
