Slashdot linked up this Aljazeera article (no, really!) detailing new research which purports to prove that dolphins are nowhere near as smart as we think they are:

Dolphins may have big brains, but a South African-based scientist says laboratory rats and even goldfish can outwit them.

Paul Manger of Johannesburg's University of the Witwatersrand says the super-sized brains of dolphins are a function of being warm-blooded in a cold water environment and not a sign of intelligence.

Sort of like cats, but with fins.
