Bats are the only kind of mammal that really flies.
As mammals, they are warm blooded, have fur, give live birth, and make milk for their babies. There are over 900 kinds of bats, but only about ten live in northeast Florida. Most of the bats in Florida are small, with wingspans of less than one and a half feet. The biggest Eastern US bat only weighs as much as 17 dimes. This is a good name for bats because their wings are actually made up of long fingers with skin in between.
