Bats are the only mammals capable of true flight. They are often mistaken for birds because of their wings, but they are actually more closely related to primates. Bats have a unique skeletal structure that allows them to fly, and they use their wings to propel themselves through the air.
Bats play an important role in the ecosystem. They are pollinators and seed dispersers, and they help to control insect populations. Some species of bats are also important sources of food for other animals.
