Dolphins are perhaps the most intelligent aquatic mammal on Earth. With their self-awareness and abilities to communicate, reason, express emotions, adapt, and perform altruistic acts, they have spread across every ocean and many freshwater rivers in the same way humans have populated every continent. The cognitive abilities of dolphins are exceptional. Below is a close examination of this mammal’s brain size, structure and remarkable cognitive abilities. Dolphins have a large, folded brain with an exceptional intellectual capacity. As a result, they learn extremely quickly and possess the ability to produce creative responses.

Although their cerebral cortex is 40% larger than that of humans, it is shallower, resulting in a neocortical volume that is 80% of that of humans. Nonetheless, both possess comparative cerebral hemispheres and folding to process sensory information and stimuli.The average bottlenose dolphin brain weighs 1.7 kg (.4 kg more than the average human brain). When comparing brain size to body size – the Encephalization Quotient (EQ), the average dolphin brain registers between 4 and 5 (second to the 7 EQ of the average human brain and significantly higher than the EQ of any other type of animal including the great apes). This indicates a close proximity to human cognitive abilities.
