Bats and dolphins are well known for using which biological navigation technique, involving emitting sound and interpreting the returning echoes?

Explanation

Echolocation is a biological navigation technique used by animals like bats and dolphins, in which the animal emits sounds, often at very high frequencies, and then listens carefully to the returning echoes as those sound waves bounce off nearby objects, allowing it to build a detailed mental picture of its surroundings, including the location, size, and even texture of nearby objects or prey. This remarkable ability allows bats to navigate and hunt effectively in complete darkness, and it similarly helps dolphins and other marine mammals navigate and locate prey in murky or deep water where vision is limited. Human-made technologies like sonar operate on a broadly similar underlying principle. Explore more Everyday Science MCQs on mcqstutor to keep practicing.
