A grizzly-polar bear hybrid is also known as a pizzly or a grolar bear. These creatures are the result of mating between a grizzly bear (Ursus arctos horribilis) and a polar bear (Ursus maritimus). The hybrid bears have a unique appearance due to their mixed parentage, with white and brown fur and a head shape that is intermediate between the two species. Another term for these bears is "nanulak," which means "polar-grizzly" in the Inuit language. Pizzly and grolar bears have become more common in recent years as climate change has caused the habitats of polar and grizzly bears to overlap more frequently.
