The pizzly bear is one of a handful of naturally-occurring animal hybrids. Also known as “grolar bears,” pizzly bears are the offspring that result from the mating of a polar bear and a brown grizzly bear. The first documented evidence of a pizzly bear was in 2006, in Canada's Northwest Territories. Hybridization of polar and grizzly bears is thought to be the result of melting Arctic Ocean sea ice, where polar bears live and hunt marine prey. The thawing sea ice forces polar bears onto land, where they are more likely to encounter and mate with grizzly bears, with whom they are closely related.
