A member of the Molossidae
family, the Brazilian free-tailed bat has the characteristic mouse-like tail protruding beyond the flight membrane stretched between its hind legs. Relatively plain when compared to many bats, this species has brown fur, large ears that are nearly square, and a strongly wrinkled upper lip. However, it is superbly adapted to its aerial lifestyle, having long, narrow wings with pointed tips to enable very fast flight, and long hairs on the toes to judge flight speed and turbulence. The hind legs are short and powerful, making this bat an excellent climber (3).
