  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!
