Dolphins call each other by name

Scientists 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.

For example, a dolphin might be expected to recognize its name if called by its mother, but the new study found most dolphins recognized names -- their signature whistles -- even when emitted without inflection or other vocal cues.

More than that, two dolphins may refer to a third by the third animal's name, said Laela Sayigh, one of three authors of a paper published in the Proceedings of the National Academy of Sciences.
