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 forearm lengths ranging from 3 cm (1 in) to 10 cm (4 in).
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 forearm lengths ranging from 3 cm (1 in) for many species to 6 cm (2 in) in the western bent ...
However, most bats in Florida seem to prefer buildings and other man-made structures over natural roosts. [8] Caves in Florida tend to be occupied mostly by the southeastern myotis. Caves in Florida tend to have pools of water on the floor and the free-tailed bats do not need as much relative humidity as the southeastern myotis. [8]
However, bats have a unique muscle group known as the occipito-pollicalis, a necessary muscle group for mammalian flight. [15] These muscle groups act to power flight and utilize the plagiopatagium which is the skin overlapping the forelimb, similar to the skin on species of flying squirrels . [ 21 ]
However, the name is arguably somewhat misleading, since only three of the other seven species of "tailless bats" genuinely lack a tail. [4] Of the remaining four, however, three have tails that are significantly shorter even than that of A. caudifer, and the fourth, the equatorial tailless bat, was only distinguished from A. caudifer in 2006.

The wing bones of bats have a slightly lower breaking stress point than those of birds. [56] As in other mammals, and unlike in birds, the radius is the main component of the forearm. Bats have five elongated digits, which all radiate around the wrist.
False vampire bats are relatively large, with combined head and body lengths that range from 65–140 mm (2.6–5.5 in). Their forearm lengths range from 50–115 mm (2.0–4.5 in). They all lack tails. The ghost bat is the largest member of the family. All the species have very large ears with divided tragi. They have long nose-leaves.
The general assembly of North Carolina considered a bill in 2007 that would have made Rafinesque's big-eared bat as its state bat. The bill passed 92-15, but died in the state senate. [3] In 2020, the big brown bat was designated the official state mammal of the District of Columbia. [4]
