<h1 class="pgc-h-decimal" data-index="01" data-track="1" > octopus</h1>
It is jokingly called an "alien creature" because it really has many characteristics that are different from other creatures. In addition to the special structure of the body, the octopus is also surprisingly smart.
First, the octopus's brain is not only present in the head, but even 60% of the neurons are distributed within its brachiopods. This means that each of its brachiopods can think and act on its own, accomplishing many complex tasks.
There is a practical example of the cleverness of octopuses, and there was once a very clever octopus in an ocean center in New Zealand, who repeatedly escaped from the tank where he was in an unknown way without the attention of the administrator. The administrators had no choice but to seal all the water tanks to prevent it from escaping.
<h1 class="pgc-h-decimal" data-index="02" data-track="14" > dolphins</h1>
How smart the dolphins are, I believe everyone has heard about it. They are also people's favorite performance animals and can make many complex movements.
In nature, dolphins are able to use their sonar to spot distant enemies and dodge in advance. They can also judge whether the creatures they are facing pose a threat to themselves and decide whether to attack.
To many people's surprise, dolphin cleverness is also used on the very dark side. Sometimes, dolphins will force female dolphins to mate, and sometimes they will prey on other animals, even humans... Therefore, dolphins that look cute are actually sometimes very dangerous, and experienced divers will stay away from dolphins.
<h1 class="pgc-h-decimal" data-index="03" data-track="38" > pig</h1>
You read that right, this animal, which we think is synonymous with stupidity, is actually very clever. Studies have shown that pigs can even feel human feelings and will express their feelings.
Moreover, pigs have a very sensitive sense of smell, not at all inferior to dogs, and there are people who raise pigs to look for truffle bacteria. However, the degree of domestication of pigs is not as high as that of dogs, so police dogs are still used at present, rather than "police pigs".
Pigs have now been raised as pets, and although they are not exactly the same as the domestic pigs we usually eat meat, their intelligence is still similar.
<h1 class="pgc-h-decimal" data-index="04" data-track="44" > dog</h1>
Speaking of smart pets, how can there be fewer dogs? How smart the dog is, I believe there is no need to introduce more, this is already a common sense. There is no need for too professional trainers, as long as you try a few times, with the right method, everyone can train a puppy to complete many actions, and they can fully understand some simple commands.
Admittedly, there is a difference between dogs and dogs, and some dogs do seem a little stupid. However, this is also the result of comparison, compared with other animals, the IQ of those "stupid dogs" is not low.
<h1 class="pgc-h-decimal" data-index="05" data-track="23" > gorilla</h1>
Speaking of intelligent animals, how can there be fewer gorillas? You know, humans and gorillas have a genetic similarity of up to 98.4%!
The one who best represents the intelligence of a gorilla is Koko. How clever is this gorilla? It can even communicate with humans, but in sign language. It's not easy, and it's made it an animal star all over the world.

There is also a famous gorilla called Harambe, who lived in 1999 when a child fell into a fence at the Cincinnati Zoo. Amazingly, the gorilla actually rescued the child and kept caressing him. However, the zoo was afraid that it would hurt the child and shot Harambe on the spot.
<h1 class="pgc-h-decimal" data-index="06" data-track="30" > chimpanzees</h1>
Yes, not all orangutans are called gorillas, they are just one of those orangutans. Compared with gorillas, chimpanzees and humans have a higher genetic similarity of 98.8%, which is the closest of all living things to humans, and their intelligence is naturally not bad.
In nature, chimpanzees already know how to use tools. They would poke a piece of grass into a termite mound, and when they took it out, it was already crawling with termites, so that the chimpanzees could have a full meal.

Britain's Daily Mail reported that one chimpanzee even knew how to use fire, which was already similar to primitive people. No wonder some people have conceived of a story like Rise of the Apes, chimpanzees are indeed very clever.
<h1 class="pgc-h-decimal" data-index="07" data-track="19" > elephant</h1>
The world's largest terrestrial animal today has a very clever mind, which shows that elephants are indeed very powerful in nature.
Today, in many areas, elephants are animals that humans can see. Being able to perform a wide variety of tasks as required is enough to prove their cleverness (we don't recommend watching animals perform).
Another clever thing about elephants is that their memory is amazing. So, if you encounter an elephant, don't mess with it. Even baby elephants who have not yet grown up can remember the faces of those who annoyed them in the first place, and launch crazy revenge when they reunite decades later, and such incidents have happened many times!
<h1 class="pgc-h-decimal" data-index="08" data-track="27" > African grey parrot</h1>
This parrot is unforgettable at first glance, because it belongs to the large parrot, with a body length of 33-41 cm, a weight of nearly 1 pound, and a lifespan of up to 50 years.
The African grey parrot is very strong in language and is very good at learning human speech, so it is also very famous. Not only that, but they are really very intelligent and have similar cognitive levels to those of human children aged 4-6.
Studies have shown that African grey parrots can distinguish between human voices and faces combined. Moreover, they are not only able to learn more than 100 words, but also distinguish objects, colors, materials and shapes, and have a relatively clear concept of volume.
<h1 class="pgc-h-decimal" data-index="09" data-track="47" > crow</h1>
Everyone has heard a story since childhood, that is, the story of crows drinking water. It is said that a crow found half of the water in the bottle and could not drink it, so he picked up a lot of small stones and put them in, raised the water level, and finally drank the water. Regardless of whether this story is true or not, the crow's IQ is still relatively high.
We don't know if crows will drink water with stones, but crows do use tools and throw nuts out of the air to break and eat the fruit. From the various manifestations of crows, some scientists speculate that the most intelligent crows in the world may even have the same IQ as 7-year-old human children.
<h1 class="pgc-h-decimal" data-index="10" data-track="51" > mouse</h1>
It is true that mice have been experimented with by humans for many years, but this does not mean that they do not have brains. Compared with humans, guinea pigs are indeed not so intelligent, but compared to other animals, it is not so. Some experiments by scientists will choose mice, and it is precisely their minds that need them.
White rats have quite good problem-solving skills and memory, and in some labyrinth experiments, they can easily escape. Therefore, for a long time, they have always been favored by scientists and used to do some psychological experiments, helping scientists achieve many research results.
