Dolphin species attempt 'common language'

[SethCochran]

Interesting article on dolphin intelligence.  It's been stated that dolphins probably handle language different than humans, and this is evidence of that.

When 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.

Dolphins are very interesting in that they too have differnt races. There are forty specises classified as dolphins though some we would commonly call whales, killer whales, fresh water dolphins etc. There are about 16 races that I can identify. Each race has its particular niche and habitat from cold water to tropical to shallow to deep water.
I found it interesting and of note that in the Caribbean the bottle nosed dolphin and the spotted dolphin often come into contact/conflict. The bottle nosed dolphins are promiscuous and prone to rape and gang rape of the females. They even rape the females of the more timid spotted dolphins producing hybrids. The spotted dolphins in return appear to have greater intelligence are more monogamous and move to deeper water to avoid the bottle noses. So there you go.. the bottle nose dolphin is the nigger of the dolphin world.
