Smoky Bat

Native to Puna Island, northern Peru, Ecuador, and northern Chile, this adorable tiny bat is only a 0.12-ounce creature that is found in caverns, pastures, abandoned buildings, and woodlands. Its length ranges from 1.5 to 2.28 inches. The smoky bat's diminutive size allows it to be concealed in cracks and other discreet locations.

Peter's Dwarf Epauletted Fruit Bat

The adorable, little megabat known as Peter's dwarf epauletted fruit bat was discovered in the woodlands of central Africa. Its size, 2.64 to 4.13 inches, doesn't take away from its appeal. The fur covering the forearms and portions of the wings is brown on top and paler below. It has large eyes, round ears, and a head that resembles a mouse. Males display white-haired shoulder pouches that resemble epaulets to entice females.

Common Pipistrelle

Not only does this small bat have a cute appearance, but also a cute name: the common pipistrelle. Its two species, which can be found in large numbers throughout North Africa, much of Asia, Europe, and the United Kingdom, were initially distinguished by the frequency associated with their echolocation signals. The soprano pipistrelle calls at a frequency of 55 kHz, while the common pipistrelle calls at 45 kHz, according to AZ Animals
