"BAT"

Bats are mammals of the order Chiroptera;^[a] with their forelimbs adapted as wings, they are the only mammals naturally capable of true and sustained flight. Bats are more manoeuvrable than birds, flying with their very long spread-out digits covered with a thin membrane or patagium. The smallest bat, and arguably the smallest extant mammal, is Kitti's hog-nosed bat, which is 29–34 mm (1.14–1.34 in) in length\

The largest bats are the flying foxes and the giant golden-crowned flying fox, Acerodon jubatus

This massive group of mammals lives in nearly every type of habitat outside of Arctic regions. You can find these creatures in fields, grasslands, forests, woodlands, rainforests, deserts, and more.

Most Bats eat one specific type of food. Different species specialize their feeding habits to obtain that food. Many feed on insects, some eat fruit and nectar from flowers, and some eat other types of  
food like blood, frogs, or fishNearly all of them feed while on the wing. They capture prey while flying through the air, snag  fruits and berries while flying, or hover to drink  nectar.
