A 2017 research paper shows that all eight of these hybrids were descended from one female polar bear mating with two different male grizzly bears. Three of the four unique hybrid cubs survived: Fridgee, Taku, and Pokodiak. They radioed in to have it darted and tested. Two male grizzlies mated with the female polar bear to give rise to the four F1s, with one grizzly bear apparently mating with the polar bear in two different years (two of the F1s are full siblings, but born three years apart). The pizzly bear is the hybrid offspring of its parents, the polar bear, and the grizzly bear. DNA testing of the bear near Sachs Harbour, Northwest Territories, on Banks Island showed the bear was a hybrid of two species.

As global temperatures continue to rise, the two species of bear are slowly congregating together more and more. The hybrid is a short-furred bear that is more adept at handling hot temperatures than the grizzly. With several suspected sightings and eight confirmed cases,[3] theories of how such hybrids might naturally occur have become more than hypothetical.

Although polar bears can adapt their diet to include sea bird eggs and caribou when on land, a 2015 study published in the journal Frontiers in Ecology and the Environment found that the calories they gain from these sources do not balance out those they burn from foraging for them, Live Science previously reported.

Prizzly bears, or grolar bears, are a hybrid of polar bears and grizzly bears. On the other hand, grizzly bears have solid hair, with only a few small sections that are hollow. Observational data does not show the two species intermixing, other than grizzlies running the much larger polar bears off.

Martells hunt took place 90 miles north of Canadas mainland. With features that could give them an edge in warming northern habitats, some scientists speculate that the pizzlies, or "grolars", could be here to stay. Hybrid bears are mostly found around the Northern Territories in Canada. All of this could result in a habitat ready for the hybrids to move in and take over, leading to a loss in biodiversity if polar bears are replaced.
