If one day, humanity suddenly disappears from the face of the earth, who do you think will be the next ruler? Is it a chimpanzee that uses tools? Or a dolphin with a language system? Or an elephant that understands gestures?
As the scientists delved deeper, everyone was surprised to find thatOctopuses are most likely the preferred answer to this question! 
Why? 1. Octopuses have a high IQ
You may have heard that octopuses are smart, but you may not know that there are studies that show that:The intelligence of an octopus is at least equivalent to that of a human child aged 6-7 years. Human beings have only one brain, one memory system. Shockingly, tiny octopuses are much more complex than peopleOctopuses have two memory systems, 3 hearts, 9 brains. One of the main brains is in the head, and the other 8 secondary brains are distributed among the 8 tentacles, and once they encounter a predator, the 9 brains will discuss and execute the escape route together. 
In many studies, scientists have been surprised to find that octopuses don't just play with toys, they also find toys for themselves, such asThe octopus will go to beat and control some small fish. Marine biologist Eduardo Sampaio said octopuses and gill perch occasionally join forces to catch small fish, when the hunt is not performing as well as the octopus expectedThe octopus will coldly punch the gill perch on the headPunch, which is in an angry warning: Hey! Man, you're in the wrong place for a little bit!
This phenomenon has occurred many times, indicating that it is not an isolated case. Octopuses have a certain desire to control other animals. 
Octopuses not only use tools to solve problems, but also plan ahead。For example, when you plan to slow down your swimming, you will find some large coconut shells or shells to carry on your body to add some resistance. Second, the octopus has the ability to shrink the bonesStrictly speaking, it's more powerful than bone shrinkingThe octopus is one of the most intelligent species among invertebrates, with very flexible tentacles that can bend and twist like a soft rope, and the ultra-high flexibility allows the octopus to easily manipulate objects in tight spaces. 
Because octopuses don't have bones, they canEasily walk through coin-sized crevices and cavesThis soft body structure allows them to adapt to a variety of different environments, especially hiding in conch shells to hunt fish and shrimp while evading enemy attacks. 3. Octopus Club **Octopuses change their shape and color to camouflage themselves and are capable of transformationImitate more than 15 kinds of creatures, just like Marvel's Witch. Some fish and shrimp that are not very good-looking, after **The octopus on the coral reef and the sand on the bottom of the sea are not aware of it, and it takes less than 1 second to become an octopus's meal. 
Some octopuses are not only highly poisonous, but can also spray ink 6 times in a row when attacked by enemies, and quickly escape under the cover of cloudy ink. Advance can be attacked, retreat can be defended. I'm afraid it's hard to find a creature in nature with such a comprehensive skill point as an octopus.
Fourth, the octopus will be reborn with severed limbsThe octopus's brachiopods have the function of regeneration, and when the octopus encounters danger, it will abandon its brachiopods like a gecko in order to save its life. When the carpal foot is broken, the blood vessels completely constrict and close on their ownThe next day, after all the wounds are healed, the octopus will begin to regrow its wrists and feet, just like Nezha in "Fengshen Bang". 
With such an inventory, it seems that the octopus is a creature from an extraterrestrial, so is there no drawback to limit it? Of course there is, otherwise the movie "Aquaman" may not be made by a human but an octopus. This shortcoming is nicknamed by folkloreGene locks。Octopuses usually live for only a few years, and this short-lived life is due to the fact that octopuses grow so fast that they can mature and reproduce in a short period of time. 
After the octopus spawns, both males and females willSuicideTherefore, the live octopus caught by humans is basically an unlucky egg that has never mated. As for why octopuses commit suicide after spawning, there are two theories:
Clause. 1. Octopuses haveCannibalismIn order not to allow themselves to eat their children, octopus parents will choose to self-destruct. Clause.
Second, the number of octopuses spawning is as high as 100,000 each time, which requires a lot of food, so in order to ensure that the baby octopus survives as much as possible, the female octopus will choose to die quietly by the side of the childLeave food for its children. 
In fact, to break the casserole in the end, it comes down to genes, according to scientists, the octopus suicidal behavior after spawningIt may be related to the chemicals secreted by the optic glands in the bodyAnyway, it's good that the octopus has been locked in the upper limit during the evolutionary process, otherwise this ocean may have to change the world.
