The second-most diverse mammalian group is unique!

Flight – bats are the only group of mammals that can sustain flight. Compared to a host of mammals that have the capacity to glide, bats can reach amazing heights because of some incredible specializations, including wings, thin skin membranes, and powerful, fast hearts.

Echolocation – bats are not the only mammalian group to use ultrasound; however, they are masters of using it to pursue prey in flight.
