HOW DO DOLPHINS SEE WHAT THEY CAN'T SEE?
Dolphins have really good eyesight, they can see well below and above water. They can also see things beyond their sight with a process known as Echolocation.
How does this work?


  •  They produce high frequency sounds (clicks) that travel through the water.
  •  This clicks are like a basketball that bounces (echoes) back to the dolphin when it hits an object.
  • The time it takes for the click to echo back to dophlin after hitting an object determines it's distance from the dolphin
  • The dolphins melon helps it to decode the received echo so as determine what the object is.  This helps it to locate food.
In summary the dolphin sends high frequency sounds (clicks) and based on the echo of the sound it is able to identify and locate it. That's  just amazing
Airport screening machines employs such technology.
