What is echolocation?
Echolocation is when a sound wave is sent out, bounces off of a surface, and then the thing that sent out the sound interprets the returning sound waves.
How does echolocation work?
Sound waves bounce off of surfaces and then echo back to the object or thing that sent out the sound waves, showing the location of the things around it.
Dolphins - They make clicking noises that bounce off of surfaces. This helps them locate food when the sound waves bounce off of the fish or whatever they are hunting/eating, the sound waves bounce back to the dolphin showing where the food is.
Bats - They also use this to hunt for food. They make high-pitched noises that send out sound waves. Those sound waves bounce off of surfaces and then bounce back to the bats to show them where things are.
Some Whales - They make clicking noises that send out sound waves. Those sound waves, bounce off of things in the water and then echo back to the whale. This tells then how far everything in the water is.
