To the Arctic: Polar Bears Rough and Tumble

Polar bears are the newest of the 6 bear species alive today, arising about 150,000 years ago, when grizzly bears living in Siberia and Alaska began venturing farther out onto sea ice to take advantage of easy seal hunting. The good ones stayed out there, and gradually became separated from grizzlies who remained terrestrial omnivores, that largely lived on plants, and were best suited to temperate climates. Over generations the seal-hunting bears adapted to being on the ice, and a new type of bear emerged: Ursus maritimus, a marine mammal and pure carnivore, the polar bear.

For more information about polar bears and Arctic wildlife, see the new IMAX® film "To The Arctic 3D" opening in select IMAX Theatres starting April 20, 2012. "To The Arctic 3D" is a MacGillivray Freeman Film from Warner Bros. Pictures and IMAX Corporation.
