echolocation

Echolocation is a natural navigation method used by some animals, like bats and dolphins. They emit sounds—usually high-frequency clicks or calls—that travel through the environment. When these sounds hit an object, they bounce back. The animal listens to the returning echoes to determine the location, distance, size, and even shape of the object. This ability helps them find food, navigate in darkness, and avoid obstacles. Echolocation showcases the remarkable adaptability of species in utilizing sound as a critical tool for survival.
