Other bats have a flatter face. Some species have folds of skin called a nose-leaf on their snout. The nose-leaf may look like a spearhead or a blade. Bats have a good sense of smell that helps them find food and their roost. Most bats have small, sharp teeth that reduce food to a soupy texture.
Bats digest their food more quickly than many other mammals.
This rapid digestion helps them avoid having extra weight while flying. Wings and legs. A bat's hands serve as its wings. Its long fingers support the flexible skin of the wings. The upper arm, forearm, and second and third fingers make up the front edge of the wing.
