Thirteen species of bat are listed as endangered.
Bats are the only mammals capable of true flight.
The bat's wing anatomically resembles the human hand, with extremely elongated fingers and a wing membrane stretched between. Almost 1,000 bat species can be found worldwide. The largest bats have a 6 foot wing span. The bodies of the smallest bats are no more than an inch long. While some bat populations number in the millions, others are dangerously low or in decline.
