Why do bats use sound waves and how?

Bats use sound waves for echolocation, a navigation and hunting technique that involves emitting high-frequency sounds and listening for the echoes that bounce back from objects in their environment. By analyzing these echoes, bats can determine the distance, size, shape, and even texture of objects, allowing them to locate prey and avoid obstacles in complete darkness. This sophisticated ability enables them to thrive in various habitats, primarily at night.
