   !TIL Early in life, each #dolphin creates its own unique vocal whistle that gives it an individual identity. Because each whistle is unique, dolphins are able to call to each other by mimicking the whistle of a dolphin they want to communicate with. It's the equivalent of calling each other by name. - https://www.bbc.com/news/science-environment-23410137 #ethology #biology
