They use their ears instead of their eyes! Bats send out sound waves (vibrations that move through air, water, and other things) from their nose or mouth. The sound waves bounce off objects. The waves return to the bat’s ears like an echo. The bats use the echo to “see.” They know where the objects are. They know the size and shape of the objects. This is called echolocation. Some bats eat insects, like moths. A bat finds a moth. It sends out many sound waves quickly. The bat knows exactly where the moth is. The bat can fly over and catch it for dinner!
