Voice 2: The bat's body is designed well! A bat is not a bird. It is the earth's only flying mammal¹! A bat's wing has two layers of skin. The skin stretches between the bat's long finger bones, then down the side of its body and back leg. The bat's 'thumb' sticks out at the front of the wing. It is free to hold on to trees and walls.
