There have been eight pizzly or grolar bears either killed by hunters or live-captured. These eight species identified include four first-generation pizzly bears with a 50:50 split between a grizzly and polar bears.

Correspondingly, where are Grolar bears found?
Grolar bears, also known as pizzly bears, are the cross between grizzly bears and polar bears. They can be found wild in Canada because global warming is causing ice caps to melt therefore forcing polar bears into grizzly habitat.
Can a Pizzly bear reproduce?
What's more, researchers believe some of the Pizzly bears found are descendants of a Brown Bear and a Pizzly Bear! Meaning, not only could they reproduce, but the offspring can be fertile! This isn't the only instance of hybridization occuring in the wild. Narwhals have mated with Beluga Whales.
