Scientists at the University of Saint Andrews in Scotland have found new evidence in the communication between dolphins. According to the study, published in the journal Proceedings of the National Academy of Sciences (PNAS), each of these aquatic mammals have a unique type of whistle by which they can identify and respond to when they hear this sound.

To conduct the survey, researchers used a group of bottlenose dolphins, recording the characteristic sound of each animal before placing speakers under the water for other cetaceans to hear them.

According to Vincent Janik, of the Marine Mammals Unit at the Scottish university, dolphins have developed this ability in order to keep the group together in the large marine habitat.
