Sperm whales may have the biggest brain sizes of any creature living on the planet, weighing up to 20 pounds according to the American Museum of Natural History in New York City. LSD experiments aside, studies in the wild have even shown some dolphins may have very human-like shortcomings. Bottlenose dolphins have bigger brains than humans (1600 grams versus 1300 grams), and they have a brain-to-body-weight ratio greater than great apes do (but lower than humans). in 2002, Marino and her colleagues examined the relative brain size of a dolphin compared to body mass something known as the encephalization quotient. Studies show that dolphins not only have the ability to learn as individuals, but those individuals can then pass their new knowledge onto others.

While understanding their behavior is much more complex in the wild, researchers have still observed a great deal of intelligent behavior in the cetaceans. The trouble is, the questionable ethics of some of his experiments often overshadows that work and led to a drought on serious research on dolphin smarts that lasted for years, Marino says. For the sake of our comparison, we will be using the brain of a bottlenose dolphin as a contrast to the average human brain. Bottlenose dolphins off the coast of Western Australia have been observed, as snout protecting tools while rooting around in the sand on the seafloor for fish.
