The trouble with many of these tests is that they occur in captive settings. The cerebral cortex is used to control higher-level thinking, motor functions, and other forms of information processing. 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 encephalization quotient is the ratio between the real and predicted brain mass of an animal-based on its body size. This kind of social learning happens frequently among wild species, but most often, the techniques that permeate animal populations involve essential tasks, such as feeding and mating. For human beings, the encephalization quotient is higher than any other animal at 6.56. Yeah, let's see a dolphin dothat.

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.

Still, he notes, "when we talk about an animal 'being smart,' it's usually when animals are doing things that look like what humans do.". Octopi, for example, may not be as high in the encephalization quotient as some of their competitors, but the cephalopods have excelled at a great number of problem-solving tasks researchers have thrown at them. In the '90s, an Indo-Pacific bottlenose dolphin population that had been the center of long-term research was observed on several occasions carrying around sponges through deep water channels.

"They are the second most encephalized beings on the planet," says Marino. One measure to take into account, considering intelligence has been repeatedly linked to brain size, is the encephalization quotient or EQ which considers an animal's brain mass compared to the brain mass predicted for an animal of its size. 454-465, doi:10.1111/j.1439-0310.1997.tb00160.x, Bearzi, Giovanni, et al.
