Dolphins "have their own names"

Dolphins communicate like humans by calling each other by name, scientists in Fife reported on Monday.

Scientists Christmas Inflatable have long known that dolphins' whistling calls include repeated information thought to be their names, but a new study indicates dolphins recognize these names even when voice cues are removed from the sound.

St Andrews University researchers studying in Sarasota Bay off Florida's west coast Florida discovered bottlenose dolphins used names rather than sound to identify each other.

"Then we played it back to the dolphins through an underwater speaker and we found they responded strongly. This showed us that the dolphins know each other's signature whistle instead of just the voice.“
