Secret Language
of Dolphins
Scientists think dolphins "talk" about everything from basic facts like their age to their emotional state. "I speculate that they say things like 'there are some good fish over here,' or 'watch out for that shark because he's hunting,'" says Denise Herzing, who studies dolphins in the Bahamas.
When the going gets tough, for instance, some dolphins call for backup. After being bullied by a duo of bottlenose dolphins, one spotted dolphin returned to the scene the next day with a few pals to chase and harass one of the bully bottlenose dolphins. "It's as if the spotted dolphin communicated to his buddies that he needed their help, then led them in search of this guy," says Herzing, who watched the scuffle.
Kathleen Dudzinski, director of the Dolphin Communication Project, has listened to dolphins for more than 17 years, using high-tech gear to record and analyze every nuance of their language. But she says she's far from speaking "dolphin" yet. Part of the reason is the elusiveness of the animals. Dolphins are fast swimmers who can stay underwater for up to ten minutes between breaths. "It's like studying an iceberg because they spend most of their lives underwater," Dudzinski says.
Deciphering "dolphin speak" is also tricky because their language is so dependent on what they're doing, whether they're playing, fighting, or going after tasty fish. It's no different for humans. Think about when you raise a hand to say hello. Under other circumstances, the same gesture can mean good-bye, stop, or that something costs five bucks. It's the same for dolphins. During fights, for example, dolphins clap their jaws to say "back off!" But they jaw clap while playing, too, as if to show who's king of the underwater playground.
