ECHOLOCATION

Did you know marine mammals like dolphins and whales use echolocation  same as the bat?. They use echolocation to locate their prey and to navigate around their environment. Bats  emit high a pitched sound and wait until it echoes back to the bat and that tells the bat there is an object. Marine mammals uses echolocation like this to.

Echolocation is not only used by animals there are very few humans that use echolocation. Ben is a boy that doesn't have any  eyes  but he uses echolocation to navigate his way.  He might not have eyes but he can locate his way through cars and ride his bike everywhere. He emits a sound clicking his tongue and he listens for an echo to see if there is anything ahead.

The people from the university of California wanted to have an experiment with Ben. They did a test to see if he could tell where the objects are and how high they were. He got all of them right but it was hard for him to tell where a thin object was  because when he emitted a sound it bounced everywhere. But amazingly he managed to locate a thin stick standing up on the table.

As you can see that some animals can use their ears to see by using echolocation to navigate their way and and to locate their prey. Not only animals that uses echolocation other humans uses echolocation like Ben. He uses echolocation to see and he emit a sound by clicking his tongue.
