Aberdeen University (Scotland) and University of Catalonia have been working , in separate groups, leading an investigation project in order to study the language codes used by dolphins to comunicate between them.
They both conclude their studies saying that dolphins actually are using codes similars to the human language. Catalan scientists added that they comunicate mainly with a sort of "body language", very similar to that used by human beings in their ordinary lives. Dolphins use short signs in their speaking loanguage as the humans do.
