The first: raccoon
Skills: lock
Previously, there are zoologists have done experiments on raccoons, even if the construction of particularly complex locks, only a number of attempts, raccoons will be able to easily open the locks, and the number of attempts is not more than ten times. This kind of IQ, really crushed a lot of ordinary human beings, especially when the key is lost, hate to have the raccoon's skills.
In addition, the raccoon's ability to learn is also very strong, after three years of systematic learning, a lot of problem-solving methods, it can easily remember in the mind. Even different symbols, the raccoon can easily distinguish, such intelligence and memory, truly enviable.
Second Species: African Grey Parrot
Skill: Reasoning
The first skill that comes to mind when mentioning parrots is that it learns to talk to humans. But in fact, there are differences in the skills and intelligence of different parrot species. As one of the smartest birds in the world, the African Grey parrot has strong reasoning skills and can even reach the IQ of a seven-year-old child.
First is its ability to mimic language, a skill that every parrot possesses. Second is the reasoning ability of the African Grey parrot, which can solve many puzzles based on logic. Even when there are no clues, the gray parrot can find the item it wants with its clever mind.
The third type: pig
Skill: reflex principle
We all use the words "stupid" and "simple" to describe the pig. The pig's life is a life of happiness. But in fact, pigs are very smart, not only can show a strong understanding of emotions and empathy, and it is easy to find a good friend, the ability to socialize is first-class.
In a 2014 experiment, piglets just six weeks old found food behind a mirror through the principle of reflection. This alone is much higher than human IQ. It's important to realize that one-year-olds are not always this observant and intelligent.
Fourth: Crow
Skill: Revenge
When it comes to crows, a lot of people don't like them and think they are unlucky birds. Especially their cawing is miserable, and in the dark night, hearing the cawing of crows will inevitably make one's heart soften. But apart from the cawing, it seems hard to find any more faults with the crow, because it is so smart that it actually knows how to take revenge.
It is said that the crow has the intelligence of a 7-year-old child, and not only can it eat tools, but also make them. Being observant is the crow's best feature, and in the experiment someone wore a mask to catch crows and tagged these crows. In the experiment, the crows were captured by someone wearing a mask and tagged with a mark, so that whenever they saw someone wearing the same mask, the captured crows would take revenge. Of course, they took their revenge in a very different way, either by chirping and cawing around or by throwing feces at others.
The fifth species: the orangutan
Skill: Rescuing humans
There's a message I've read before: humans evolved from orangutans. Originally, I had doubts about such a statement, but after reading the relevant experiments, I suddenly believed it. As primates, orangutans are supposed to be one of the most intelligent, using tools to build nests and sign language to communicate with their peers.
It is reported that in a nature reserve, a staff member accidentally fell into the water, and the one who saved him was actually an orangutan. The rescued staff member said: I used to think that orangutans are smart, but I didn't realize that it is actually so smart, and very observant, but also particularly caring.
