Funnel-eared Bats

The family Natalidae, or funnel-eared bats, are found from Mexico to Brazil and the Caribbean islands. The family has three genera, Chilonatalus, Natalus and Nyctiellus. They are slender bats with unusually long tails and, as their name suggests, funnel-shaped ears. They are small, at only 3.5 to 5.5 cm (1.4 to 2.2 in) in length, with brown, grey, or reddish fur. Like many other bats, they are insectivorous, and roost in caves.

Geographic changes and isolation methods have affected the differences among species within this family of Natalie's. Like the Natalus from Cueva La Barca, males seem to have longer tibias and greater skulls than that of females and when comparing them to the Greater Antilles, they have the largest body in the genus.
