Bats may fly in the night, but there’s no reason to fear these amazing mammals! Bats are one of the most common types of mammals on the planet and live on almost every continent. Most bats eat insects, some eat fruit, some eat nectar, and a few even eat blood. They are amazing creatures: not only are they the only flying mammal, but they also use echolocation to find their food and navigate in total darkness. Bats are cool!
