The only mammal that can truly fly is the bat. Bats are part of the order Chiroptera, which means "hand wing." Their wings are adapted from elongated fingers covered by a thin membrane of skin, allowing for powered flight. This adaptation enables bats to be highly maneuverable flyers, pursuing insects and navigating through dark environments using echolocation. Bats play crucial roles in ecosystems as pollinators and pest controllers. With over 1,400 species worldwide, they exhibit a wide range of behaviors and habitats, showcasing their adaptability and ecological significance.
