What Is echolocation?

What Is echolocation? Echolocation is something that non humans can use to see. Also echolocation is when you make a sound with your mouth and clicking with your mouth or fingers.  Bats use echolocation to navigate and find food in the dark. Echolocation is the use of sound waves and echoes to determine where objects are in space.

Bats send out sound waves from their mouth or nose. When the sound hits an object it produces an echo. Toothed whales can send ultrasounds that cannot be heard by humans to catch their prey. The other animals that use echolocation produce sounds that are audible to humans.

Ben Underwood was blind, but he was able to move around using echolocation. He was blind at the age of three. He has good hearing and is incredible with his movement. Ben Underwood had a habit of using echolocation. To use echolocation he made little clicking sounds with his mouth and also he clicks with his fingers to find his way around.

He is the only boy in the world thats blind but could do things normally. He can ride a bike, he can play basketball, he can surf.
