How do dolphins use echolocation?

Dolphins use echolocation to navigate and hunt by emitting high-frequency sound waves, which bounce off objects and return to the dolphin’s ears as echoes. By analyzing the returning sound waves, dolphins can determine the size, shape, and location of objects, including prey. This ability is especially useful in murky or dark waters where vision is limited. Echolocation allows dolphins to navigate, communicate, and efficiently locate fish and other food sources in their environment.
