And so they “see” by echolocation. That’s their thing.
Why do bats give off high-pitched squeaks?
Bats use high-pitched calls to echolocate because only at those ultrasonic frequencies can they detect their small, swiftly moving insect prey. But high-frequency calls don’t travel far through the air, leaving bats unable to detect prey beyond a few metres.
