The assessment of intelligence is based on a combination of factors: social behavior, solving non-standard tasks, good memory, and others. Research shows that many animal species are capable of learning, using tools, recognizing emotions, and even abstract thinking.
Dolphin

Dolphins live all over the world’s oceans, they are annual visitors to the Arctic and Antarctic. Dolphins are often called the smartest animals in the world, and this claim has serious scientific grounds. Their intelligence manifests itself not in a single skill, but in a set of complex cognitive, social, and emotional abilities that are rare in other species.
Dolphins are considered the intellectual leaders of the animal kingdom because of their high level of brain development. The relative size of a dolphin’s brain is comparable to that of a human, and its structure is characterized by a high number of convolutions, which is associated with information processing, memory, and learning. Dolphins have well-developed areas responsible for social interaction and emotions.
Special attention of researchers is attracted by the dolphins’ ability to self-awareness. In experiments with a mirror, they recognize their own reflection, which is considered a sign of advanced intelligence and was previously recorded only in humans and some primates. This suggests that dolphins are able to recognize themselves as a separate person.
An equally important factor is their complex communication system. Dolphins use a wide range of sounds, including clicks and whistles, as well as individual “names” — unique signals by which individuals recognize each other. This form of communication requires a developed memory and the ability to think abstractly.
The intelligence of dolphins is clearly manifested in the ability to learn. They easily learn new commands, are capable of imitation and even improvisation, finding non-standard solutions in changing conditions. In the wild, dolphins use collective hunting strategies, assigning roles within a group, which indicates a high level of coordination and understanding of the actions of others.
The social life of dolphins also indicates their high intelligence. They form stable groups, take care of injured and sick relatives, help the cubs and demonstrate behavior that can be interpreted as empathy. There have been cases where dolphins have helped other animals and even humans, which highlights their emotional development.
All these features allow us to conclude that dolphins are not just intelligent animals, but creatures with complex intelligence combining thinking, emotions and social skills. It is this versatility that makes them the main candidates for the title of the most intelligent animals in the world and continues to arouse the interest of scientists around the world.
Chimpanzee
Chimpanzees are rightfully considered one of the most intelligent animals on the planet, and this is confirmed by many years of scientific observations. Their intelligence manifests itself in the ability to think, learn, and interact with the world around them at a level close to human.
One of the key features of chimpanzees is the ability to use tools. In the wild, they make sticks for termite mining, stones for cracking nuts, and leaves as sponges for water. These actions require an understanding of cause and effect relationships and the ability to adapt to environmental conditions.
Chimpanzees have developed memory and learning abilities. They quickly learn new skills, memorize sequences of actions and can transfer knowledge to other members of the group. That is why different populations of chimpanzees have their own “traditions” and behavioral features, which can be called the beginnings of culture.
Their social organization is also important. Chimpanzees live in complex communities with hierarchies, alliances, and rules of behavior. They are able to recognize the emotions of their relatives, show empathy and cooperate for a common goal. All this makes chimpanzees one of the most intellectually developed animals and the closest “competitors” of humans in the animal kingdom.
Octopus

The main feature of octopuses is their ability to solve complex problems. In experiments, they open jars, memorize shapes and colors, find their way out of mazes, and learn quickly from their own experience. This indicates a well-developed mindset and excellent memory. Interestingly, a significant part of the octopus’s nerve cells are located in its tentacles, which allows them to act almost autonomously.
Octopuses are highly adaptable. They are able to change the color and texture of their skin, disguising themselves as the environment, and also use improvised objects such as shells or coconut shells for protection. This behavior requires an analysis of the situation and decision-making.
The intelligence of octopuses is also reflected in their curiosity. They actively explore the world around them, react to new objects, and are able to recognize individuals.
Elephant
Elephants combine advanced intelligence, emotional sensitivity, and complex social behavior. One of the main features of elephants is their exceptional memory. They are able to memorize routes, water sources and dangerous places for decades. In addition, elephants recognize their relatives even after a long separation.
Elephants’ intelligence also manifests itself in their ability to solve problems. They use improvised objects to get food or protect themselves from insects, demonstrating an understanding of cause-and-effect relationships. In experiments, elephants show the ability to learn and adapt to new conditions.
A special place is occupied by their social and emotional development. Elephants live in close family groups, take care of cubs, help the wounded, and are able to experience emotions similar to empathy and grief. All this makes elephants not only intelligent, but also one of the most emotionally developed animals on the planet.
The Crows
The intelligence of crows is often compared to that of primates, and the research results surprise even scientists. Crows demonstrate advanced thinking, excellent memory, and the ability to solve complex problems. Crows have an outstanding memory. They remember people’s faces, especially those who posed a threat to them, and can recognize them years later.
One of the most impressive features of crows is their ability to use and craft tools. In experiments, they bend a wire to get food, or sequentially use several objects to achieve a goal. This behavior speaks to the ability to plan actions and understand cause-and-effect relationships.
In addition, these birds are able to learn by observing others and pass on knowledge within their group. The social behavior of crows also indicates high intelligence. They live in complex communities, interact with each other, signal danger, and are able to cooperate.
The smartest animals in the world are not just primates. Dolphins, elephants, crows, bees, and even shellfish exhibit abilities that until recently were considered exclusively human. The study of animal intelligence changes our understanding of the world and forces us to take a fresh look at the place of man in nature.
