Grolar bears. The offspring of a grizzly bear and a polar bear, a grolar bear is one beast you don't want to meet in the woods. Interestingly, unlike many hybrid animals on this list, grolar bears are known to occur naturally in the wild.
The movement and distribution of grizzly bears are becoming predictable. These species remain active for 6 to 8 months each year. What Do Grizzly Bears Eat.
