Explanation: Echolocation is a biological sonar used by several kinds of animals, including bats. They emit sound waves that bounce off objects in their environment, allowing the bats to determine the location, distance, size, and even shape of objects based on the returning echoes. This ability is essential for navigation and hunting in the dark.
