The animal known for its ability to fly but is not a bird is the bat. Bats are the only mammals capable of sustained flight, and they belong to the order Chiroptera. Unlike birds, which have feathers, bats possess wings made of a thin membrane of skin stretched between elongated finger bones. Bats are incredibly diverse, with over 1,400 species worldwide, playing essential roles in ecosystems as pollinators and pest controllers. They use echolocation to navigate and locate food, which typically consists of insects, fruits, and nectar. Bats are fascinating creatures that contribute substantially to environmental health.
