First, a caveat: "You can't really rank animals by intelligence because they're all designed to do different things," says Justin Gregg, Ph.D., a senior research associate at the Dolphin Communication Project and the author of Are Dolphins Really Smart?. Dolphins have been declared the world's second most intelligent creatures after humans, with scientists suggesting they are so bright that they should be treated as "non-human persons". They'll even emit their unique whistles especially loudly when they're in distress. By that measure, human brains, by comparison, are seven times average. Two male bottlenose dolphins were tested using this method in 2001, and researchers determined that they not only recognized themselves, but provided a "striking example of evolutionary convergence with great apes and humans. The hippocampus is a somewhat small region in the human brain that is shaped like a seahorse. But, conversely, the dolphins had always believed that they were far more intelligent than man for precisely the same reasons.. Dolphins, like primates, crows, and sea otters, also use tools, a skill once thought to be possessed by only humans. The more similar to human intelligence that dolphin intelligence is the more likely it is that dolphins may in fact be smarter than humans as Adams predicted.

Renowned dolphin researcher Louis Herman referred to dolphins as humans' "cognitive cousins" on account of the many characteristics they share with humans and great apes, even though cetaceans and primates are only slightly related. Cognition is an umbrella term used to describe high level brain functions like thinking, knowing, remembering, judging, and problem-solving.

This Brilliant Dolphin Has Outsmarted Her Trainers In One Amazing Way Dolphin brain close to that of a human, but they also have the capacity for intricate emotions and reasoning. She and her colleagues made spots on different parts of dolphin bodies using markers then observed the creatures going to look at that specific spot in a mirror placed in their tanks. Now that scientists know so much about how dolphins think and feel, she said, they should use that data to build a bridge to the publica big theme of this year's meeting.
