How do bats see in the dark?

Browse → Animals → Small Mammals
Bats come out at night to hunt for food. As they fly through the sky, they seek insects like moths and beetles. But it’s dark at night! How do bats see the critters that will become their next meal? 
While some think that bats are blind, these mammals can actually see! However, sight isn’t the most important sense when it comes to hunting their prey in the dark. In fact, as they hunt, bats use a technique called echolocation. They make a high-pitched noise with their mouth or nose, releasing sound waves into the air. The sound waves hit the insect and bounce back, creating an echo
From the echo it hears, the bat can tell the shape and size of the bug, as well as where it is! As you may imagine, this information comes in handy during hunting time!
