Echo location is a natural navigation technique used by certain animals, such as bats and dolphins. These creatures emit sound waves that bounce off objects in their environment. By listening to the returning echoes, they can determine the distance, size, and shape of nearby objects, helping them to navigate and hunt. This ability is particularly useful in dark or murky environments where visibility is limited. Bats, for example, use echo location to find insects while flying at night. Similarly, dolphins use it to locate fish and navigate through the ocean, showcasing the remarkable adaptations of these animals.
