The only mammal capable of true flight is the bat. Bats are the only mammals that have developed the ability to fly, and they do so with powered flight, using their wings, which are essentially modified forelimbs. Bats are highly diverse and can be found in various ecosystems worldwide, playing essential roles in pollination, seed dispersal, and insect control. There are over 1,400 species of bats, each with unique adaptations for their specific habitats and diets.
