Detailed explanation-1: -Echolocation, also called bio sonar, is a biological sonar used by several animal species. Echolocating animals emit calls out to the environment and listen to the echoes of those calls that return from various objects near them. They use these echoes to locate and identify the objects.

Detailed explanation-2: -Nature’s own sonar system, echolocation occurs when an animal emits a sound wave that bounces off an object, returning an echo that provides information about the object’s distance and size. Over a thousand species echolocate, including most bats, all toothed whales, and small mammals.

Detailed explanation-3: -Echolocation is a technique used by bats, dolphins and other animals to determine the location of objects using reflected sound.

Detailed explanation-4: -(1) Bats produce high-frequency sounds to hunt for their prey. (2) Dolphins and other toothed whales use sound waves to locate their prey and navigate their surroundings. (3) Nocturnal oilbirds use echolocation to navigate their surrounding, especially those with poor lighting conditions.
