The fastest bat, the Mexican free-tailed bat (Tadarida brasiliensis), can achieve a ground speed of 160 km/h (100 mph). [52] Little brown bat take off and flight. The finger bones of bats are much more flexible than those of other mammals, owing to their flattened cross-section and to low levels of calcium near their tips.

They live in South Asia , Southeast Asia , Australia , East Africa , and some oceanic islands in the Indian and Pacific Oceans. [ 3 ]

Recently, there have been comparative studies of mouse and bat forelimb development to understand the genetic basis of morphological evolution. Consequently, the bat wing is a valuable evo-devo model for studying the evolution of vertebrate limb diversity. Diagram showing homologous skeletal structures of bat and mouse
The Molossidae, or free-tailed bats, are a family of bats within the order Chiroptera. [1] The Molossidae is the fourth-largest family of bats, containing about 110 species as of 2012. [ 2 ] They are generally quite robust, and consist of many strong-flying forms with relatively long and narrow wings with wrinkled lips shared through their ...
