Is it true that dolphins have a name?

The dolphins are animals that live in groups. When in the ocean, they communicate with each other to stick together. Sounds like an unique whistle is used to identify one another.

"When a dolphin hear her call, they respond," said Dr Vincent Janik, of the University's Sea Mammal Research Unit. The study, conducted by a team of University of St Andrews in Scotland is published in the Proceedings of the National Academy of Sciences on the July, 2013 issue.

Janik explained, dolphins live in a three dimensional environment that far offshore. Then, he said, they need a very efficient system to keep in touch with one another. Indeed, scientists have long suspected that the dolphins use whistles as well as the typical man who called each other by name.

Previous research found that the call is often used, and the dolphins are in the same group was able to learn and mimic sounds unusual. But this is the first time the animals respond to something that leads to their "name."

To reveal it, the researchers noted a group of bottlenose dolphins, capturing the sound signal produced by each dolphin. Then the researchers played back the call by using an underwater speaker.

"We played whistle markers and animals in the group. We also played another whistle in their repertoire and whistles markers of different populations," Janik said.

The researchers found that people only respond to their own call, the whistle sounded again. This mammal acts like a human, i.e. they answer when they hear his name called.

Janik said these skills may appear to help these animals in order to stay together in a group in an underwater habitat. *** [EKA | FROM VARIOUS SOURCES | BBC NATURE | ROSALINA | KORAN TEMPO 4303]
