Grizzly bears are large, powerful mammals found mainly in North America, particularly in places like Alaska and Yellowstone National Park. They have a distinctive hump on their shoulders and can weigh between 400 to 1,500 pounds. Grizzlies are known for their brown fur, which can vary in shade, and their long claws, which help them dig for food and climb trees. These bears are omnivores, meaning they eat both plants and animals. Their diet includes berries, fish, and small mammals. Grizzly bears are also known for their impressive strength and speed, making them one of the most formidable animals in the wild.
