The bear's paw is smaller than the bear's right paw. This is because in the process of using the left palm and the right palm, the frequency of using the left palm is high, so the muscle development of the left palm is high, which makes the volume of the left palm relatively small.
The hind paw of the bear's paw has knuckles, but the front paw doesn't. The front paw is much smaller. This is because in the process of using the rear paw and the front paw, the use frequency of the rear paw is higher, so the structure of the rear paw is more complicated, while the use frequency of the front paw is lower, so the structure of the front paw is relatively simple.
