This flexible skin membrane that extends between each long finger bone and many movable joints make bats agile fliers Bats are the only mammals capable of true and sustained flight, distinguishing them from other mammals like flying squirrels, which can only glide short distances. While other mammals like flying squirrels can glide, bats can flap their wings, achieving greater control and distance, which distinguishes them from all other mammals Bats are also equipped with a sophisticated echolocation system, allowing them to navigate and hunt in complete darkness.
