What if dolphins are listening in on their prey--and their prey are listening right back? Researchers spent two months eavesdropping on dolphins along Florida's Atlantic coast, using an autonomous wave glider to capture their underwater sounds and clues about where they socialize and hunt. The study revealed distinct acoustic hotspots where dolphins gathered and socialized, and where they hunted in areas rich with sound-producing fish. The findings open a fascinating new question: Are dolphins and their prey listening to--and potentially responding to--each other?
