How Bats Navigate in Total Darkness

Bats are the masters of the night sky, and their secret is echolocation. They emit high-frequency sound pulses that bounce off objects and return as echoes, creating a sonic map of their environment. This isn’t just for obstacle avoidance; some bats can detect a human hair or a moth’s wingbeat from meters away. The calls are so loud they’d be deafening, but bats protect their own hearing by contracting a muscle in their ear just as they call. This biological sonar is so sophisticated that it’s inspired sonar and radar technology used by humans. It’s a perfect example of evolution creating a superpower.
