The mammal capable of true flight is the bat. Bats are unique among mammals as they possess the ability to sustain powered flight, unlike other mammals that may glide or jump. Their wings are formed from a membrane of skin stretched between elongated fingers, allowing them to navigate through diverse environments efficiently. Bats play critical roles in ecosystems by contributing to pollination, controlling insect populations, and helping to disperse seeds. With over 1,400 species, bats are a vital part of many ecosystems and demonstrate remarkable adaptations for survival.
