The Qimen poison in martial arts** either comes from this ** or from that snake, and these animals that can extract toxins are called "on the rivers and lakes".Five poisons
It is always called five poisons and five poisons, which five animals are called, I'm afraid many people don't know.
The five poisons are centipedes, snakes, scorpions, geckos and toads, according to legend, these five animals contain highly poisonous, although it sounds very bluffing, but in fact, there is a strange injustice in this, the gecko is a little cutie who has removed insects, and it is not poisonous.
The basic standard of the five poisons is the highly toxic organisms that can be used as drugs by the Chinese people.
The name of "Five Poisons" is domineering, but Gecko said, do you want this domineering? So, what kind of animal exactly is a gecko? Why is it the Five Poisons? What's so magical about it in itself? What should we think of it?
Gecko is a general term for the gecko family of lizards, compared to several other members of the "five poisons", geckos are actually more cute, with a pair of large eyes of Carslan, and the pupils will contract with the intensity of the light, showing different eye lines.
Geckos have scales on their bodies, and different species of geckos vary greatly in color, and some are more high-profile and long-lookingColorful；Some are low-keyGray does not slip awayTarget.
The most famous is actually the gecko'sCornices walk on the wall, which is also the origin of its name.
A gecko with a stunt that can do light work.
If you want to redivide the sect, the gecko should not be counted as a poisonous sect, it takes the route of light power.
Many people believe that geckos are able to hold on to walls because they have suction cups on their feet.
At first, zoologists thought so, but when you zoom in thousands of times under an electron microscope, you can see that there are thousands of bristles on it, and these bristles will form van der Waals forces with the surface of objects, and the geckos rely on van der Waals forces to nail themselves firmly to the wall
The toes of the gecko themselves are non-sticky, but the adsorption and desorption are easily controlled.
There are more than 90 genera and 900 to 1,000 species in the entire gecko family, and geckos can be found on every continent except Antarctica.
Geckos are relatively small, nocturnal, feed on insects, and most of their members are not very large, with a body length of between 5 and 15 centimeters.
Of course, just like there are Yao Ming and Guo Jingming in human beingsThere are also larger members of geckos, such as large geckos, which can grow to more than 30 centimeters
Commonly known as the clam, the tail length is equal to or slightly longer than the head body length, and it is the largest kind of gecko.
In general, geckos do not actively approach people, not to mention that geckos have neither fangs nor venom glands, and always silently scratch insects in places where people can't see.
Why are such harmless animals added to the "five poisons"? Why is gecko considered one of the "five poisons"?
According to the records of geckos in ancient books, the urine of this little thing is poisonous! It is said that after being stained with the urine of the gecko, it is extremely itchy and will ulcerate and pus, so the gecko mentioned in the martial arts** is poisonousIn fact, it is extracted gecko urine
Zoologists have found that there is no toxic component in the gecko's urine, but it'sVery acidic
That is to say, the series of symptoms that appear after being stained with the urine of the geckoNot poisoned, but corroded by acid
So why is geckos' urine so acidic? This is because geckos eat all kinds of bugs, and many bugs contain acids in their bodies, as we often sayFormic acid in ants, eating these insects for many years, acidic substances are also deposited in the gecko's body.
Formic acid is a colorless liquid with a pungent odor.
In addition, this is also the same as that of geckosBody structureRelate.
Its ancestors lived in very arid areas in the early daysTherefore, the gecko's own urine is concentratedAlthough geckos are small in size and have less urine, it is no wonder that such a high concentration does not make people uncomfortable when exposed to **.
Another point is that geckos are cloacal animals, and their urine and feces are excreted through a hole, so their rectum is relatively short, a bit like a bird that pulls after eating
When the gecko climbs on the wall, it is actually pulling while walking, and it will inevitably fall on the person's **.
Envy my digestion.
The ancients found that after being crawled by geckos, ** festered, they thought that the gecko was poisoned.
Due to the nocturnal appearance, many geckos hide in some narrow, dirty, and dark environments in order to avoid natural predators, and it is inevitable that they will get into some germs or something
When it crawls over the human body at night while the person is asleep, these germs also come to the human body.
I came quietly, unaware.
The ancients didn't know this, but they thought that after the gecko came, people had bad phenomena, so they thought that the gecko was poisonous.
Over time, geckos have been classified as the "five poisons" along with poisonous snakes, scorpions, toads and centipedes, and everyone is afraid.
Although modern science has cleared the name of geckos, in many cultures, geckos are not positive characters, they are still terrifying.
This is because geckos have a jaw-dropping stunt-Tail breakage and regrowth
Tail docking is an act of self-defense, in order to evade the enemy.
For the vast majority of animals on the planet, if they are missing arms and legs, the wounds can be healed, but the lost arms and legs cannot grow back.
The gecko can cut off its tail on its own, and then grow a new tail in a short time, and it is a "good man".
Therefore, when the ancients saw that the gecko's tail was broken and it could still run, they thought it was incredible, and thought that its bones were strange and there must be demons
Zoologists have analyzed different cells from geckos' body parts and found thatGeckos are able to control the rapid apoptosis of the cells of their own tails, using the force of their muscle contractionsThe tail separates from the body, and the predator is attracted by the broken tail, so the gecko takes the opportunity to escape.
Gecko: The tail is for you, give me a little life.
The cells in the gecko's tail are extremely differentiated, so the tail grows over a period of time.
The gecko's such cells are distributed only on its tail, if one of the gecko's feet is cut off, it cannot regenerate like a tail.
The part of the tail is not fixed, some are cut off the whole tail, some are cut off half of the tail, and some even only break one tail tip, and the amount of loss varies from gecko to gecko.
Although the severed tail does not threaten the life of the gecko, but with such a large wound, the gecko often goes to some dirty corners, what if it is infected
Gecko: Call an ambulance for me.
In addition to the tail part of the cells of the gecko has strong apoptosis and redifferentiation ability, it also has:Extremely resistant and immune
In the process of evolution, the gecko has learned to coexist with many germs, and it fights poison with poison, using these germs to inhibit wound infection, and has evolved a super anti-infection ability.
For geckos, a single broken tail is not worth mentioning at all.
Strong resistance and immunity are the basis of the body's self-protection.
The gecko's miraculous tail regeneration ability is the envy of humans, and if there is one thing that geckos are scary, it is itThe super self-healing ability is terrifying
If we can crack the genetic secrets of geckos, we can take a big step forward in medicine, so it's time to change the old brains, geckos are not the "five poisons", on the contrary, it is an animal group with extremely high research value.
First of all, we have to admit that the gecko is not poisonous, and the people it causes are not because of its venom, but because its urine is acidic, and there are many germs on its body.
Secondly, geckos are timid by nature and will not actively attack people, and even if they do, it will not do any physical harm to humans.
Finally, geckos eat insects and are beneficial to humans, especially mosquitoes, ticks and mites, which transmit virusesIf the gecko is wiped out,In the end, it is these pests who benefit
Ticks and mites are numerous and can also spread diseases.
The ancient record of gecko deaths is related to the poor living environment and medical conditions in the past.
At that time, eating some spoiled food was life-threatening, so it was possible for geckos to make people sick or even die, which is why people used to fear geckos.
In fact, some species of geckos in modern times have adapted to human urban life and are completely able to get along with humans, as long as they do not deliberately touch the wild geckos, it is best to keep a distance from them, then it can become a walking "mosquito killer".
Some brightly colored geckos,It has become a pet of humans
Who can refuse a pet gecko that has always been cute and obedient.
However, it should be reminded that some pet geckos are not obtained legally, and due to the rise of the pet industry, some geckos have lost their populations, and the situation is precarious.
So if you want to raise geckos, you still have to think twice.
Being regarded as the "five poisons" is actually the ignorance of geckos by the ancients, and geckos have also suffered a lot of unwarranted disasters for this reason.
We now know more about geckos and know that they are not only non-venomous, but they can also catch insects for humans, yesThe so-called "beneficial insects".
Therefore, there is no need to exterminate them like the ancients, there is nothing terrible about geckos, on the contrary, they are a little cute!
