Bats use sound to see in the dark. When they fly, they make little clicks and whistles, and the echoes come back to them like a game of ping pong, this helps them know where everything is. It's kind of like when you shout in a big empty room and hear your voice echo back.
Examples
- A bat makes a click, and the echo comes back like a reply to its question: 'Where is my insect?'
- Imagine shouting in a large hall, you hear your voice echo back. Bats use this same idea, but with tiny clicks.
- It's like playing hide-and-seek, but instead of guessing, the bat listens for echoes.
