Bat

A bat is a mammal in the order Chiroptera. The forelimbs of all bats are developed as wings, making them the only mammals naturally capable of flight (though other mammals, such as flying squirrels, flying possums and colugos, can glide for limited distances). The word Chiroptera comes from the Greek words cheir (χειρ) "hand" and pteron (πτερον) "wing," as the structure of the open wing is very similar to an outspread human hand with a membrane (patagium) between the fingers that also stretches between hand and body.
