Dolphin self masturbates with beheaded fish

The intelligence of dolphins is one of their most outstanding features. Among the thousands of members that the animal kingdom has, dolphins take one of the top places regarding intelligence.

The brain is the organ involved in the ability of understanding, reasoning, learning, and other cognitive processes. The dolphin’s brain is astonishingly complex, almost comparable to that of humans. And it is large related to their body. Through magnetic resonance imaging, their brains have been found to be 4-5 times bigger than those of other animals of similar sizes.

The bottlenose dolphin (Tursiops truncatus) is the second place in a list of species with a higher encephalization ratio (EQ), which compares the mass of the encephalon against its body size.

In addition to a developed neocortex, the cerebellum has more convolutions (turns of the brain surface) than that of other mammals. The connections between the neurological areas and the motor areas of the organ exhibit a great sensitivity to pain and a pronounced tendency to stress.

Most of their behaviors show the development of their brain and their ability to understand situations. They process information from their environment in a similar way to people, and some say that they can solve problems like humans. For example:

  • Their forms of communication are complex, evolving and diverse.
  • They are creative and playful animals. Their behavior is not mechanical or rigid; they seem to enjoy playing and look for the companionship of other individuals.
  • Their empathy suggests that they experience emotions such as sadness or joy.
  • They have an excellent learning ability; this is why they are highly requested animals for water parks, although the activities of these places are highly controversial.
  • They can transmit learning to other generations of dolphins. There have been cases where they use tools. For example, sponges to protect your snout from rough surfaces.
  • The members of a pod collaborate with each other and sometimes with other species of animals.

Some scientists argue that the social intelligence of these cetaceans competes with that of the great apes because they can demonstrate empathy towards the companions and help them when they are injured or immobilized.

Signs of higher intelligence are related to self-awareness and dolphins are. Proof of this is that when they look in a mirror, they can recognize themselves and know that they are the ones in the mirror; This is a sign of the development of abstract thinking. Likewise, their learning ability is comparable to that of a 3-year-old child, according to cognitive psychologist Diana Reiss of the New York City University.
