A picture illustrating the location of the calcar on a bat. The calcar, also known as the calcaneum, [1] is the name given to a spur of cartilage arising from inner side of ankle and running along part of outer interfemoral membrane in bats, [1] [2] as well as to a similar spur on the legs of some arthropods.
They range in size from the Amazonian sac-winged bat, at 3 cm (1 in) plus a 1 cm (0.4 in) tail, to the Pel's pouched bat, at 14 cm (6 in) plus a 4 cm (2 in) tail. Like all bats, emballonurids are capable of true and sustained flight , and have wing lengths ranging from 3 cm (1 in) to 10 cm (4 in).
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
It is composed of 270 bones at the time of birth, [2] but later decreases to 206: 80 bones in the axial skeleton and 126 bones in the appendicular skeleton. 172 of 206 bones are part of a pair and the remaining 34 are unpaired. [3] Many small accessory bones, such as sesamoid bones, are not included in this.

The connection between the stylohyal bone and the tympanic bone enables the bat to neurally register the outgoing and incoming ultrasonic waves produced by the larynx. [11] Furthermore, the stylohyal bones connect the larynx to the tympanic bones via a cartilaginous or fibrous connection (depending on the species of bat).
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. [53] [54] The elongation of bat digits, a key feature required for wing development, is due to the upregulation of bone morphogenetic proteins (Bmps).
