Scientists have found enough evidence to determine that dolphins are capable of calling each other by name.
Researchers have revealed that dolphins set a unique whistle to identify each other according to BBC.com.
Scientists from the University of St. Andrews in Scotland determined that when dolphins hear their own "call" played back to them, they respond. When another "call" was played for the dolphin they didn't respond.
"(Dolphins) live in this three-dimensional environment, offshore without any kind of landmarks and they need to stay together as a group," said Dr. Vincient Janik from the university's Sea Mammal Research Unit. "These animals live in an environment where they need a very efficient system to stay in touch."
Now it's not like they're calling each other names like Jim and Bob, but they do use a stunning repertoire of whistles, clicks, and buzzes to communicate amongst one another.
The "calls" are important during a hunt for prey or if another dolphin wants to play according to Janik.
The findings were published on July 22 in a journal titled "Proceedings of the National Academy of Sciences." Past research said individual dolphins had personal whistles, but it was a never a determined as fact before now.
The findings also discussed the similarities between dolphin whistles and the human language.
"As humans, we are able to learn new sounds, and dolphins and parrots can also learn new sounds," said study co-author Stephanie King to LiveScience.
