The brown bear, or grizzly, is a large strong mammal. It lives in forests and mountains, swims well and can run very fast.
The brown bear stands out for its great strength, long claws, and ability to hibernate in a den. It is important for nature because it spreads plant seeds and helps maintain balance between different animal species.
