When polar bears mate with grizzlies they produce grolar bears.
Biologists in the Northwest Territories have confirmed that an unusual-looking bear shot near Ulukhaktok, N.W.T., was a rare hybrid grizzly-polar bear.
The grolar bear had thick white fur like a polar bear, but it also had a wide head, brown legs and brown paws like a grizzly.
Wildlife DNA analysis shows the bear was a rare second-generation hybrid.
The bear was the result of a female grizzly-polar hybrid mating with a male grizzly bear.
