• Question: We are learning about sonar in science class. Don't bats use this? Do bats have eyes?

      Bats use echolocation (so do dolphins and whales), which is VERY similar to sonar and radar. Echolocating animals use high-frequency calls and listen to how they reflect off different objects, and use that to navigate or catch prey. However, this doesn’t mean they’re blind. All bats and dolphins/whales can actually see as well as we can, or better, with their eyes – echolocation simply helps them maneuver in complex environments even better!
