A new study has revealed that dolphins, which are believed to be the cleverest creatures in the animal kingdom, may not possess high intelligence.
Zoologist Justin Gregg, author of 'Are Dolphins Really Smart?' said that in terms of intelligence they are nowhere near as special as they have been portrayed, the Daily Express reported.

The researcher also claimed that other scientists had made mistakes, most crucially that dolphins' large brains equal greater intelligence and that the complex sounds they make are a form of language.
