As you know, bats are the only flying mammals, and, as their bodies became increasingly specialized for flight over the course of evolution, most species lost the ability to walk. Only a couple of exceptions are known, including a species of bat that lives in New Zealand and the common vampire bat of South and Central America. While other bats can only shuffle, these bats use their wings as forelimbs, so they can walk around like any other four-legged animals. Learn more on this Moment of Science.
