Dolphins name themselves | Science News for Kids

Dolphins name themselves | Science News for Kids: "To call a dolphin, just whistle a squeaky shout-out.

Bottlenose dolphins answer to high-pitched bursts of sound. But each animal responds to only one specific trill. That trill is called its “signature whistle,” explain Stephanie King and Vincent Janik of the University of St. Andrews in Scotland. Their new finding appeared June 22 in the Proceedings of the National Academy of Sciences.
Each dolphin develops a signature whistle — a distinct tune — for itself. Dolphins broadcast their tunes to others. The tunes seem to act as a sort of audible nametag."
