Ever heard of a Grolar? How about a Pizzly? Actually, they are the same animal; a cross between a polar bear and a brown grizzly. The offspring show fascinating characteristics of both species; they are midway in size between the two species, have long necks like polar bears but shoulder humps like grizzly bears.

Most interesting is their pelt; polar bear hair is hollow for added insulation, grizzlies have solid hairs but the coat of the offspring is a mixture of the two.

Some experts predict that polar bears may be driven to breed with grizzly bears at an increased frequency due to global warming and the fact that polar bears are being forced from their natural habitats on the polar ice.
