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.
