How do bats use echolocation to navigate?

Bats use echolocation to navigate and hunt for food in the dark. They emit high-frequency sound waves from their mouths or noses, which bounce off objects and return as echoes. By listening to the returning sound waves, bats can determine the size, distance, and shape of objects in their environment, including prey. This ability allows bats to hunt insects and navigate through dark caves or forests without relying on sight. Echolocation is essential for many species of bats, especially those that hunt at night.
