Patagia on a flying squirrel. The patagium (pl.: patagia) is a membranous body part that assists an animal in obtaining lift when gliding or flying.The structure is found in extant and extinct groups of flying and gliding animals including bats, theropod dinosaurs (including birds and some dromaeosaurs), pterosaurs, gliding mammals, some flying lizards, and flying frogs.
They range in size from the Shortridge's long-fingered bat, at 3 cm (1 in) plus a 3 cm (1 in) tail, to the great bent-winged bat, at 8 cm (3 in) plus a 7 cm (3 in) tail. Like all bats, miniopterids are capable of true and sustained flight , and have wing lengths ranging from 3 cm (1 in) for many species to 6 cm (2 in) in the western bent-winged ...
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
A bat wing, which is a highly modified forelimb. Bats are the only mammal capable of true flight. Bats use flight for capturing prey, breeding, avoiding predators, and long-distance migration. Bat wing morphology is often highly specialized to the needs of the species. This image is displaying the anatomical makeup of a specific bat wing.
The common name bent-winged bat refers to their most obvious feature, the group's ability to fold back an exceptionally long third finger when the wings are folded. This finger gives the bats long, narrow wings that allows them to move at high speed in open environments and in some species to migrate over a distance of hundreds of kilometres.
