Grizzly bears are a North American sub-species of brown bear which includes the Alaska kodiak bears.
Grizzly bears get their name and are distinquished from other brown bears by the whitish tips of their fur. Historically, grizzly bears had a large range extending from Mexico, through the continential United States and Canada to Alaska. Today they are limited to a few national parks in the United States and are considered nearly extinct. As with all bears, grizzlies have strong, massive jaws, thick, powerful legs and feet. Each toe has a long, sharp claw.
