Calcar
Townsend long-eared long-eared ears ( Corynorhinus townsendii ) with clearly recognizable, taut tail skin
The calcar is a cartilaginous spur in flight and gliding animals, which serves to support the flight and gliding skin.
In bats it is formed on the hind legs and stretches the tail fly skin (uropatagium) between the calcar, hind leg and tail of the animals. In some species, such as the noctule bat ( Nyctalus ), it also carries the epiblema , a stiff piece of skin in the tail membrane.
A calcar can also be found in other animals, such as the sliding planes . This is a cartilaginous brace on the forearm, on which the sliding skin formed between the front and rear legs is stretched.
