The big naked-backed bat (Pteronotus gymnonotus ), is a bat species from South and Central America.
Instead of attaching to the sides of the bat, its wings attach to its back near its spine.This gives individuals the appearance of having a "naked back" due to the lack of fur on its wings.However, its back is furred under the wings.Individuals weigh 12–16 g (0.42–0.56 oz) and have a forearm length of 49–56 mm (1.9–2.2 in).It has a dental formula of 2.1.2.32.1.3.3 for a total of 34 teeth.
The big naked-backed bat is found in Central and South America.Its range includes the following countries: Belize Bolivia, Brazil, Colombia, Costa Rica, Ecuador, El Salvador, Guatemala, Guyana, Honduras, Mexico, Nicaragua, Panama, Peru, and Venezuela.It has only been documented at elevations below 400 m (1,300 ft) above sea level.
As of 2008, it is evaluated as a least-concern species by the IUCN.It meets the criteria for this classification because it has a wide geographic range; its range includes protected areas; its population is presumably large; and it is unlikely to be experiencing rapid population decline.
