Storyboard Text

  • Bats have a special skill it is called echolocation. A bats eyes can't see too well so they depend on echolocation to survive
  • Bats let out high frequency squeaks that echo off of objects showing it where they are so it can avoid obstacles and find food. It helps a lot that a bats ears are big, so they can hear the echos better.
  • Bats can eat half their body weight everyday in bugs and their children weigh a quarter of their soon to be full weight, so that means without echolocation bats might not survive in the wild.
  • Did you know that whales use echolocation just like bats? They do it by blowing out air to create little clicks and then suck the air back in to create more!
  • Whales use echolocation to find food and to help navigate underwater and so do dolphins.
  • Krill
  • Scientists found that to make a click at depths of 500 meters (1,640 feet), the whales may use as little as 50 micro-liters of air. (the volume of a drop of water) So we know it doesn't take a lot of air!
