Echolocation, also called bio sonar that is used by several kinds of animals. Echolocating animals emits calls out that ricochets back to to the animal now it knows how big and how far the object is. Echolocation is used for navigation and for hunting in various environments. Some blind people may have learnt how to use echolocation by either using a clicking device or making sound by mouth. Bats,  mammals, , a few birds, dolphins and toothed whales use echolocation. Some of the bats make the sound through their noses.

There was a teenage boy named Ben that had learnt how to use echolocation by making a clicking sound from his mouth. One day Ben and his mum were driving past a big building when Ben said to his mum "Mum can you see that big building out there?" His mum replied "Can you see that big building out there?". Ben had noticed that the sound in the car had changed when they went past the big building. Now Ben knows how to ride a bike and he knows how to shoot a ball in a hoop.

So in conclusion Echolocation is used by animals, marine mammals and some humans to locate objects in their surroundings. Echolocation is like a replacing eyes for people that are blind.
