Some bats have a head shaped like that of a miniature bear or dog. 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.
