Dolphins and porpoises use echolocation for hunting and orientation. By sending out high-frequency sound, known as ultrasound, dolphins can use the echoes to determine what type of object the sound beam has hit. Researchers from Sweden and the U.S. have now discovered that dolphins can generate two sound beam projections simultaneously.
