A 2018 study published in Science found as sea ice continues to decline, "polar bears are likely to experience increasingly stressful conditions and higher mortality rates." Hybrid polar-grizzly bears are taking over. Two of her cubs were full genetic siblings, even though they were born a whole three years apart. The pizzly bear is a polar bear-grizzly bear hybrid.

The shape of the head is different for both parents as well. They also have a highly specialized, meat-only diet. The pizzly bear is an example of the hybridization of two different species and has caused controversy, primarily from a conservation standpoint. Since there are only a handful of officially confirmed pizzly bears in the wild, more research needs to be done to better understand unique hybrid animals. The answer might soon be common knowledge, as climate change has pushed these two species of bears together. Its coloration was pissy-mountain-goat-butt-white with some brown in the mix. Josh Hawkins has been writing for over a decade, covering science, gaming, and tech culture. However, many hybrid species cannot reproduce beyond this first generation. Since then, sightings of pizzlies in the wild have become more common. But it will take time and additional research to know how well suited these hybrids are to survival.
