If dolphins are so smart why do they live igloos?

JOHANNESBURG - Dolphins may have big brains, but a South African-based scientist says lab rats and even goldfish can outwit them. Paul Manger of Johannesburg's University of the Witwatersrand says the super-sized brains of dolphins, whales and porpoises are a function of being warm-blooded in a cold water environment and not a sign of intelligence. "We equate our big brain with intelligence. Over the years we have looked at these kinds of things and said the dolphins must be intelligent," he said. |

Manger also points to the tuna industry, which under consumer pressure has gone to great lengths to prevent dolphins from being caught and killed by accident in nets. "If they were really intelligent they would just jump over the net because it doesn't come out of the water," he said. |
