Is spider silk endless?

It is endless, the spider silk spit out by the spider is composed of protein, as long as the silk pulp in the stomach is not used up, you can pump as long as you want, theoretically you can pump the spider silk while feeding the spider. Little Zhuge Liang.

Sit firmly in the military tent and set up a gossip array.

Catch the fly alone. That is to say, spiders, spiders generally walk alone, do not like to live in groups, and live alone in the animal world.

In the group, all kinds of spider silk are their **. <>

First, the formation of spider silk.

Most spiders have 6 silk slurry holes in their stomachs, and then there are many small holes at the tail end, when the web is formed, the spider can spray the spider silk out of its stomach, and the spider's protruding spider silk is very sticky silk, because it is composed of proteins, so the web made of it, no matter what flying insects hit it, they can't escape. Spiders are usually found in the corners of the jungle and face death if the prey accidentally collides with them.

Second, the predation mode of spiders.

Spiders are the natural enemies of insects, and the spider silk produced by spiders is also a great weapon for insects, spiders generally have poison sacs, and the toxins in the poison sacs have paralyzing properties, as long as the prey accidentally hits the spider web.

The spider will go down the web. The prey is re-wrapped, then waits for the prey to die, and finally eats it. The spider silk spit out by the spider is very tough, and can generally withstand the weight of prey 10 times larger than itself.

Third, the role of spider silk.

Cobwebs are 5 times stronger than steel bars. Spider silk is so elastic that a silk with a diameter of only 1 10,000 mm needs to be elongated more than twice as long before it can be broken. And the spider silk is also very fine.

Therefore, it is widely used in the military field. For example, body armor worn by military personnel.

It's made of spider silk. In addition, the thinness of spider silk can be used as surgical sutures.

With the development of science and technology, human beings have become more interested in bionics.

The research is getting deeper and deeper, and spider silk has also brought us a lot of inspiration.

Yes. Because spider silk spinning is an instinct, and the spider's body is able to continuously produce spider silk, spider silk is endless.

Spider silk is not endless, it needs to supplement food to transform into spider silk, so spider silk is limited unless it eats all the time.

The spider's silk is not endless, and it will take a period of time to precipitate after the spider silk in its body can continue to vomit. It's like a human spitting and can't spit out the words after spitting.

Yes. But after the silk is vomited, the spider can be said to be lifeless.

Spiders will not vomit out their own silk, even if they build webs and vomit the spider silk temporarily, as long as they rest for a while, the silk pulp will be produced in the stomach again, and they can continue to vomit silk. They have a variety of glands in their stomachs that make silk pulp, and they are able to secrete a liquid bone protein, which is spit out of their bodies by spiders and condenses into spider silk that is both tough and sticky.

The formation of spider silk is actually not spit out by spiders, but is expelled from the abdomen by spiders, and spider silk is just a very viscous liquid when it is first discharged, and it quickly condenses into spider silk after contact with air. There are generally 3 pairs of spinning devices in the abdomen of the spider, and the spinning devices are connected to the silk glands in the body through thousands or even tens of thousands of tiny tubes, and the silk glands will produce various glandular fluids according to the different life stages and different needs of the spider, which will be stored in the stomach of the spider to meet the needs of the spider when the spider discharges these fluids to form spider silk for web-building, escape, making egg bags, predation and other needs.

When the spider wants to build a web, it will discharge the glandular fluid stored in the stomach through the spinning tube through the pressure in the body, and the glandular fluid will undergo chemical reactions and physical changes after contact with air, and it will quickly condense into silk threads. Spiders are very clever in the process of spinning silk, they will stick the discharged glandular fluid to a fixed object, and then move their bodies quickly, or let their bodies fall from the air, so that the spider silk is pulled out of the body to form a silk thread, if the spider is held down in the process, the spider cannot move quickly and cannot spit out the silk. This shows that the spider silk is not actually spit out, but is pulled out by the spider, and if the silk spit out by the spider does not start to fix its position, or if it cannot move its body, it will not be able to produce the silk.

Although the strong spider silk looks very delicate, it has excellent toughness and strength, and is called "biosteel" by scientists, and is the strongest natural fiber known to mankind. Even if a relatively large bee hits a spider web at high speed, the web will not be damaged by this impact force and will remain unscathed in most cases. The elasticity of spider silk is mainly due to the irregular arrangement of protein molecular chains in it, coupled with its strong viscosity, which makes spider silk look like a liquid spring.

No. Because spider silk is a special substance, and the spider's body can continuously produce this substance, the spider will not vomit its own silk.

The spider does not spit out its own silk, because if it spits out its own silk, the spider will also die, and of course it will not do that.

Spiders don't spit out all of their silk, spiders will keep some of it for prey or for emergencies, and won't use it all up.

Organs with silk-strapped nets.

The spider's abdomen has 3 pairs of protrusions, called the textile apparatus, and there are many textile tubes on the textile apparatus that communicate with the silk glands in the body, which are at the posterior end of the abdomen and are connected to the textile organs on the surface through many microtubules.

The principle is that spiders have six glands in their abdomen; Known as silk spinning devices, various glands produce different types of spider silk, and the top of the gland has a spinneret with thousands of small holes on it, and the liquid sprayed out condenses into viscous and tense spider silk when it encounters air.

The spider's silk is not spit out of the spider's mouth, it is pulled out

There are multiple silk glands at the tail end of the spider's abdomen, and the raw material of spider silk, silk protein, is usually stored in the silk gland in the form of liquid. In addition, the spider has 3-4 pairs of organs called spinners in the abdomen, and its textile tubes communicate with the silk glands, and when needed, these fluids will flow out of the silk glands, through the textile tubes into the spinl, and then be expelled into the air. The spider silk, which was originally liquid, hardened quickly in the air and became the silk thread form that we see every day.

When making spider silk, spiders usually need to fix the silk liquid at one point and then move their bodies quickly to pull the silk liquid into a thread shape, so to be precise, spider silk is not spit out, but "pulled" out. If the spider silk is removed from the fixed point, or the spider's abdomen is immobilized so that it cannot move, the spider will not be able to produce the spider silk properly.

The strength of the spider silk

Someone has done a special study and found that the strength of spider silk is much higher than that of steel wire of the same thickness. Spider webs can remain unscathed even after stopping fast-flying flying insects, and it is estimated that it only takes a pencil-thick spider silk to stop a Boeing 747 in flight.

Spider silk is also outstanding in terms of elasticity, flexibility, heat resistance and ultraviolet resistance, and is called "biosteel" by scientists. In addition, spider silk also has a very wide range of application prospects in clinical medicine and artificial organs.

Spider silk mainly comes out of the small hole of the spider's tail, the tail part of the spider, there is a sac, the spider will secrete some mucus through the protrusion at the tip of the silk sac, when these mucus encounter air, it will soon condense into a small filament. The web made of this silk will be very sticky, and when all kinds of small insects fall into the spider web and cannot escape, it becomes the food of the spider. Now you know, we've all seen Spider-Man

Definitely, but only about half of all spiders weave webs. Some spiders spin silk to help escape, such as spinning silk wraps to protect themselves, and hanging a silk from the ceiling to the air or the ground. What's the secret of spider spinning?

Different spider silk has different characteristics such as strength, elasticity and toughness, but through research and comparison with natural materials and synthetic materials, it is found that spider silk is much stronger than them, and the tensile strength of each spider silk is twice that of steel, and the elasticity is much better than that of man-made fibers. For example, a spider web can extend up to 10 times its original length, while nylon breaks once it reaches 20 times its original length.

Through observation, it is found that each spider is followed by a spider silk, which we call traction silk, which can be said to be the lifeline of the spider and plays a very important role in the spider. When the spider falls from the top of the cover, it acts as a safety rope to ensure the safety of the spider's life; When the spider encounters danger, it acts as a ** line to transmit an alarm to the spider in time to ensure that the spider escapes in time; At the same time, the most important radial radius line of the spider web is also composed of traction wires.

Not all spiders spin silk.

Of the more than 40,000 species of spiders in the world, not every one of them can build webs, but almost all of them can spin silk, and only a few cannot. Because there are several pairs of textiles at the end of the spider's belly. It was from the small holes that the spider silk flowed out of it.

Its composition is protein, which is similar to silk, and when it first comes out, it is still a glue. But as soon as it touches the air, it immediately hardens into silk.

Because spiders are highly sensitive to changes in environmental factors including habitat structure, habitat type, wind, humidity and temperature, they can be used as indicator groups to monitor the changes of residual habitats and biodiversity, and their species composition and population changes have become important indicators for environmental monitoring, which can well reflect the process of environmental change and its impact on biodiversity.

Spider Lifestyle:

The lifestyle of spiders can be divided into two main categories. That is, the nomadic type and the sedentary type. Safari type is a spider that hunts everywhere, hunts, has no fixed residence, does not destroy webs, does not dig holes, and does not build nests. There are scaly arachnidae, ursoaradae and most tarantulas.

Sedentary: some build nets, some dig holes, and some build nests as fixed dwellings. Such as wall money, stone-like spiders, etc. Spiders seem to be polite, and those who live independently keep a certain distance from each other and do not invade each other.

Compared to ordinary insects, spiders are long-lived, most spiders complete a life cycle, generally 8 months to 2 years, and male spiders are short-lived and die soon after mating. Others such as water spiders and cunning spiders can live for 18 months, burrowing tarantulas can live for 2 years, cancer spiders can live for more than 2 years, and birdcatcher spiders can live for up to 20 to 30 years.

All spiders live by the use of silk, silk secreted by the silk gland cells, in the gland cavity is a viscous liquid, through the spinning tube out, when it encounters air quickly condensed into a filament, the specific gravity of the silk is, strong and elastic.

Cave spiders are inside their webs during the day and at the entrance of their burrows at night, waiting for opportunities to hunt or go out to forage. The male spider digs a shallow pit under the clods, the burrowing tarantula digs a deep vertical hole in the ground, and the dancing spider adds a trap at the entrance of the hole. This type of flap is made up of multiple layers of filament.

The hole of the spider is up to 1 meter deep, the spider is small, poisonous, and dies in four minutes after biting the burrowing hare.

Do all spiders spin silk? The answer to this question is not simple. First of all, it needs to be clarified that silk is not a single substance, but a complex of multiple complex molecules.

Therefore, different species of spiders spit out different silks. Biologically, silk is mainly used for predation, mating, movement, and protection. Not all spiders are able to spit out silk, though.

Spiders belong to the phylum Arthropods, and silk is secreted by its glands. Some spiders have silk glands that are not fully developed or lack certain key enzymes and are therefore unable to spit out silk. At the same time, some spiders will also lose their ability to spin silk due to reasons such as living in a boring environment, such as spiders living in dry environments.

In addition, different species of spiders also have different uses and characteristics of silk. For example, some spiders have very tough silk that is suitable for building webs and nests, while others have very thick silk that is suitable for predation. There are also spider silk that can be used for flight, floating, and gliding.

Thus, for each spider species, their silk has a different structure, characteristics, and uses.

In conclusion, although not all spiders can spit out silk from die pins, for those who are able to spit silk, their silk has a very wide range of uses and properties. This is not only a unique life experience, but also provides many interesting research directions for scientists.

First of all, let's talk about the principle of spider spinning.

At the end of the spider's belly, there is a pair of "looms" that produce a special type of slime. The mucus flows out of the 6 holes at the end of the tail, and as soon as it comes into contact with the air, it immediately solidifies. Spiders use their hind feet to gather this slime and pull it into silk, which then weaves a web.

The "slime" that spins silk in a spider's body can be synthesized autonomously. Therefore, the total amount of silk spun by spiders in their lifetime is definitely limited, but at the point where it can independently synthesize "slime" spinning, it is a ...... that can spin indefinitely
