There Is Someone In There

Dolphins who hear their own signature whistled by another dolphin call back. They don’t respond to a dolphin who whistles a third dolphin’s signature call. In other words, they call each other by name, and they answer when they hear their own name called. Dolphins call their close friends’ names when they are separated. No other mammal seems to do that (that we know of).
