In one study in 2002, Marino and her colleagues examined the relative brain size of a dolphin compared to body mass something known as the encephalization quotient. How intelligent are whales and dolphins? Many people are aware that pigeons were used during wars as messengers due to their ability to remember people and places for several years at a time. The trouble with many of these tests is that they occur in captive settings. In fact, humans have a larger brain than dolphins relative to their body size.

Nine out of 12 goats mastered the task after four tries. White of Loyola Marymount University, and Chris Butler-Stroud of the Whale and Dolphin Conservation Society, who proposed the document during the world's largest science conference (the American Association for the Advancement of Science in Vancouver, Canada) in 2012, said dolphins should be perceived as "nonhuman persons" because they exhibit individuality, consciousness, and self-awareness. But sperm whales are also massive animals that require more computing power for basic tasks like movement. They're known to use sticks to catch ants and termites, as a kind of rudimentary form of a fishing (or, rather, bug-catching) pole. Defining exactly what it means to be a person is difficult, White said, but dolphins seem to fit the checklist many philosophers agree on: They're alive, aware of their environment, and have emotionsthose ones are easy. Only a few other species like chimpanzees have been shown to exhibit this type of self-awareness.

The many cetaceans witnessed pushing deceased pod mates in the water for days have provided substantial anecdotal evidence that dolphins feel grief, a complex emotion experienced only by social creatures with large, complex brains.
