Dolphin’s clicks help scientists sort through confusing underwater noises

Bottlenose dolphins can teach scientists how to tell the difference between noisy echoes bounced off of bubbles and other objects.

Dolphins hunt using sonar, sending clicks through the water and listening for the echoes. When its clicks bounce back, an animal knows where to find its dinner. But dolphins have also been observed blowing out streams of tiny bubbles as they hunt. Scientists now realize those clicks provide a means to sift through and find useful underwater sounds.
