Dolphin species attempt 'common language' (http://news.bbc.co.uk/earth/hi/earth_news/newsid_9045000/9045389.stm)
QuoteWhen two dolphin species come together, they attempt to find a common language, preliminary research suggests.
Bottlenose and Guyana dolphins, two distantly related species, often come together to socialise in waters off the coast of Costa Rica.
Both species make unique sounds, but when they gather, they change the way they communicate, and begin using an intermediate language.
That raises the possibility the two species are communicating in some way...
Fascinating!
Just like humans. The Brazilians and Argentines speak a mixture of Portuguese and Spanish when they meet each other, which they call portenhol.
I think we could learn a lot from dolphins....and basically every other animal on Earth.
