Spider silk and silk silk... spiders

And silk silk, I mean silkworm silk, is silk
The most famous and luxurious.

It is surprising that spider silk is finer, thinner, and lighter
From silk silk. And what is more dangerous than all of these is that he is stronger.

Some people tried to produce spider silk for trade, but their efforts were unsuccessful. One of the reasons for this is that a domesticated spider must continue to live alone, eat alone, seek food alone, and all of that and other things, which is a great expense.

However, spider silk is used in making optical devices because it is the finest thread known to date.

- Not all spiders weave webs

Not all spiders weave to make webs to catch their food. Many spiders hunt for their food like a beast hunts. It hides until the opportunity comes and leaps, but weaving has many other purposes. It is used to defend against the enemy, such as a wasp, for example, as weaving makes it impossible. It is used to make the cocoon in which the female spider protects her eggs and continues to guard and care for them. It uses a container in which the male's sperm is collected before it is impregnated with the female... and so on.

The spider on the ceiling wants to come down to the ground.
So what does he do? He prints some of his liquid silk on the ceiling, then begins to make a single thread that he dangles to the ground. He increases his work as he descends, until he reaches the ground. If he wants to ascend, he keeps this rope and climbs on it.

This is how it moves from tree branch to branch. He throws his rope, which is light, and the wind carries it until it is tied to the other branch. And on the emerging bridge it is easy.

(This is a spider's web that took the drug Pervitin, which increases activity and reduces patience. The spider's patience went away, so it contented itself with weaving a small side space.)

(Then Caffeine, which is the active ingredient in coffee, makes the spider weave a house like this. It is a random thread in complete darkness.)

Spiders weave webs of many shapes

Each species of spider has the shape of its own house that it builds. Some of these shapes are like a sheet, some are like a funnel, and some are geometric and circular. And so on.

The most complex, complex, and well-made of these nets, when completed, usually consists of: The circular geometry has three or four basic threads surrounding it, several other basic threads interspersing within it, and then many radii emerging from one center. Then a navel at this center of close-knit circular tissue, then a middle area, then another. Sticky, to stick to the victim, so he cannot escape.

The threads that the spider had to make differed due to their different purposes, and therefore the glands that make the liquid silk in the spider’s abdomen differed in what they were made of.

(This web is a result of the action of chloral hydrate, which is the famous sleep aid. The spider fell asleep because of it after weaving a little of this house.)

(Finally, this woven house, which is fully woven and beautiful. The reason for this is that the spider took the acid to which the famous drug known as L.S.D. is related, so its consciousness became sharper, as it does in humans.)

that . Each specializes in a type. One type works when it wants to produce, and another stops.

And weaving, who taught the spider how to weave? And geometry, whoever taught him its lessons, he knew the circle
And he knew the diameters of the circle? .

And viscosity, I wish my hair knew the meaning of viscosity.
And drought, and the objectives they entail.

And the spindles, not all of them produce one type, please
My poetry: How did the spider know that one species had had enough of it, so it stopped its spindle, and that another species needed it, so it released its glands!?

Nerves in spiders

And spiders are where all this is going on, from
Movement to catch, grind catch, digest catch, and suck
From hunting, and before that, spiders made their homes from silk fabric, which contains coordinated thought, and hands or feet that spin and weave. All of this must have a pioneer. In man, it is the brain, from which emerges the spinal cord, and from the spinal cord are hundreds, even thousands, of nerves distributed throughout the body more severe than the distribution of workers in a massive factory in its various sprawling units and numerous specialized departments.

This characteristic of spiders is the nerves that are most crowded in the chest and head of their body, and become thinner and thinner in the abdomen.

Things that the person seeing them cannot see except with lenses and microscopes, and their maker made them without a lens or microscope. She does it with spiders, but she does not know it. She gives it. I do not think that spiders have awareness of what they sense when they are given, and this awareness is specific to humans. And few people are aware.

The good thing is that they do not become fully aware. If this awareness is complete, it disrupts life. Because life requires heedlessness in order to achieve its goal. One minute of complete awareness is enough for the truth to be revealed to a person as he takes his last step on the surface of this dirt.

- Drugs act in spiders just as they do in humans

Finally, we come to the research they conducted on drugs that indicated how much they were affected by them and how.
They used spiders just as they used experimental animals, such as mice, rabbits, guinea pigs, and so on.

An example of this is a fly that they injected with an active drug, fed it to a spider, and let it weave as usual, then they looked at the resulting web.
They linked the drug to the description of the fallen web that the spider had given him, and these pictures are some of what they revealed:

The results of this research were that an unknown drug given to a spider can reveal the nature of this drug through its tissue, based on the shape of the resulting tissue.

From this we see that drugs that work in the human nervous system are drugs that work in a similar way even in the nervous system of spiders. The resemblance between the two nervous systems is strange. His wonder is increased by the distance between humans and spiders in the animal ranks.

(And there is no living creature on earth, nor any bird that flies with its wings, except nations like you.)
