Dolphins Don't Have Names, They Have "Whistles"
- -
ach dolphin makes its own unique whistle, and close friends or family will reply with the same sound. The findings, published today (July 22) in the journal Proceedings of the National Academy of Sciences, suggest the dolphins use the whistles like names. Past research showed individual dolphins had personal whistles, but it wasn't clear that other members of their group learned that whistle.
