Echolocation is the sound that is heard when you make a sound and it rebounds off an object or thing. You can hear the echo if you are in a cave and you shout out. It sounds like a double voice.
Some animals like whales, bats, and dolphins can use echolocation. Bats have really good hearing because of the size of their huge ears. dolphins have really good hearing too. They use echolocation to find fish.
Ben Underwood was a kid who had eye cancer. Aquanetta who was Ben’s mum spotted something wrong with his eyes when he was two years old. His real eyes were taken out and he was given fake ones. Ben used echolocation to find his way around.
