Bats are the only mammals that can sustain flight and belong to the order of Chiroptera. A bat's "wings" are formed by the spreading of the digits at the end of their limbs. There are two main types of bats: insectivores that eat insects and frugivores that eat fruit. There are over 1,100 different species of bat. The smallest bat is less than two inches in length while the largest bat is over four foot in length.

Like bees, bats pollinate flowers and spread fruit seeds helping to sustain the natural environment. Without the dispersion of seeds performed by bats, many tropical plant species wouldn't survive.

Bats utilize a system of echolocation in order to understand their environment. Bats call out using ultrasonic sounds and measure the returning echo for clues to their location. Bats aren't actually blind but do suffer from poor vision which makes echolocation essential for understanding their geographic location. Bats have excellent hearing and smell.

Bats are nocturnal meaning they conduct their activities during the night. Hunting for prey is performed using the echolocation system. Bats emit an ultrasonic sound when they fly which bounces off potential prey and back to the bat so he can find them. Bat feces also referred to as guano is a potent fertilizer.
