All species have broad heads, extended jaws, massive frames, heavy paws, powerful claws, and shaggy coats. Bears vary in size according to their species. Bears are plantigrade, or flat-footed, animals. The heel of the foot rests on the ground, like the human foot. The toes end in enlarged claws that are especially adapted for digging out small rodents.
Bears move both legs on one side of the body forward at the same time.
This gives them a deceptively clumsy gait. They are actually swift and agile animals and are able to stand on their hind legs and strike out with their front paws. Most bears climb trees with ease and swim well. A bear normally has a short, thick neck, a rounded head, pointed muzzle, short ears, and small eyes. Some species have round faces.
