Which mammals fly?
Many species have developed to integrate aerial mobility over time. Some of them have accomplished this via flying or gliding. Bats are the only flying mammals. Others can glide from tree to tree, but bats are the only animals that can fly propelled. Have you ever wondered if there are any other creatures that can fly besides birds? You would be accurate if you thought of bats. Bats are the world's only flying mammals.
The bat's arm bones and four fingers are slimmer, lighter, and longer. These are the primary flying adaptations of the bat. A thin membrane called the patagium covers the wings as well. The patagium is the membrane that joins the forelimbs to the hindlimbs. The membrane allows the bat to move more naturally and quickly than other birds. The arms are responsible for supporting, spreading, and manipulating the membrane. Bats' forelimbs evolved into wings to allow them to fly. The bat's thumb is not linked to the wing. The thumb can still stick to surfaces. This is especially useful while the bat is napping. A fantastic thing about bats is that their hind limbs bend backward while their feet face forward.
