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.
In general their home range is between 10 and 380 square miles. A grizzly bear's home range is basically inland - away from major bodies of water. In most cases, a grizzly bear's home range includes an area of forested land or shrub cover, which is used mostly for escape (Jonkel 1984, p 21). Food Types: Grizzly bears feed on berries (blueberries, bearberries, etc.), roots, bulbs of plants, ground dwelling rodents, and most importantly whitebark pine nuts.
