Bat Wings
Bat wings are made of two
thin layers of skin stretched over the bat's arm and fingers. Bats
have a thumb and four fingers, just like people (sorry, you can only see
3 of the fingers in my photo -- it's tough to get a bat to pose!).
The bat's fingers are
very long compared to its body. If we had fingers like a bat, they
would be longer than our legs!
Bat wings go all the way
down the side of the bat's body and partway down its legs. |
