Bats can be found on all continents except Antarctica and live in a variety of habitats. Many bats roost in trees, caves, or man-made structures. They play an important role in ecosystems by eating insects, fruit, nectar, pollen, and small fish. Bats use echolocation, smell, and vision to locate different types of food. Their large ears, nose, eyes, claws, and wings help bats survive and find resources in their environments.
