How do dolphins communicate? Cracking the code of the mammal’s whistles and clicks

For more than 30 years, Marine mammalogist Denise Herzing and her team have studied the behavior and cognitive abilities of wild spotted dolphins living in shallow water off the Bahamas.
“I see them probably more than some of my human friends, to be honest,” Herzing said. “They have personalities, they have different ways of greeting you sometimes, so they’re unique in their own right as well.”
Over time, the group has compiled a large database of the dolphins’ whistles, clicks and other sounds and hope to use the information to crack the code of their underwater communication system.
“What we discovered is that indeed there seems to be this regularity to the sounds,” said Thad Starner a Georgia Institute of Technology computer scientist collaborating with Herzing. “Just by looking at the audio, we can predict what you’re seeing in the videos.”
