What is echolocation?

What is echolocation? Echolocation is when you use echoes or sound to detect things and find out where something is. Some animals in the dark use echolocation to navigate through the dark, and to find food to eat as they sleep during the day. Dolphins also use echolocation to find food and to communicate with families miles away.

There is something also called bio sonar (echolocation), which is another tool that people, whales and dolphins use to navigate through water. Sailors use sonar to find shipwrecks and to navigate through rough seas.There is a downside to sonar in the marine life. If dolphins hear sonar they immediately rush to the surface of the water and this can make air bubbles in the tissue of dolphins and it can lead to eternal bleeding.  

Other animals such as bats use echolocation to hunt down their prey. They make a little sound with their mouth and it vibrates to the prey and bounces back. That determines and pinpoints where the prey is and then they go in for the kill. That’s why bats sleep at during the daytime and why they have such big ears that are curved inwards.

Ben underwood was a person who suffered eye cancer at the age of two. His mum spotted something different in his eyes. His eyes were removed. He learnt how to use his other senses, especially his hearing. He used his mouth to click. The clicks vibrated off objects so he knew where the objects were. He was unique because he was the only person in the world to use echolocation.
