Dolphins, like humans, recognize names

Bottlenose dolphins can call each other by name when they whistle, making them the only animals besides humans known to recognize such identity information, scientists reported on Monday.

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.
