View of a Grizzly Bear paw. See how big the Grizzly Bear paw appears. It can measure over 30 cm. Notice the large toes, the claws that extend past the paw, and the padding underneath. The grizzly bear and the polar bear have about the same size of paw. The difference lies in the amount of fur beneath the paw and the length of their claws.Andrew Derocher, Canadian Wildlife Service.
