Talk about it
A bat sends out sounds and listens for the echoes bouncing back — echolocation. By whispering, these bats sneak up on prey that would otherwise hear a loud call.
- How does a bat use sound to find prey in the dark?
- Why would whispering help these bats catch careful prey?
- What information does a returning echo give the bat?
