How to play the most curious spiders and cobwebs?
What is spider silk used for? I believe that even children cry. I thought it was used to weave nets to catch bugs. This is true in most cases, but just like the human world, there are always some deviant species in spiders, and they have developed various subtle or sand sculpture ways to spin silk.

As a safety rope

Jumping spider is a common animal, because it likes to prey on flies, so it is also called flying tiger in many places.

This kind of spider often lives on tree trunks and higher branches. Others will lie on the indoor walls of rural houses. When it finds flies with its lovely Kazilan big eyes, they will quickly move above (or obliquely above) the flies, and then tie the spider silk to a solid place.

After these preparations, the spider will not hesitate to pounce on the flies and kill them with its claws. Of course, sometimes they miss, and then the safety rope they wear works. They can tighten the safety rope so that they don't touch the ground, then climb back along the safety rope and wait quietly for the next chance.

As a stroller,

The marsupial spider is a very responsible little animal. After laying eggs, they will wrap the eggs with spider silk for fear that the children will be hurt.

Some species are even more heartbreaking for their babies. When going out, I am afraid that my children will become left-behind children, so I take a big bag of children out. Without this spider silk stroller, I really don't know how Mother Spider would take these little guys away.

When the meteor hammer hits its prey.

Bora spider is a spider native to America. Although this spider relies heavily on spider silk, it does not weave a web, but rolls into a ball and hangs on its hind legs.

Then he will smell the smell and attract moths to mate. When happy moths find the smell coming, they will throw their spider silk balls out at a very fast speed, and the moths that are hit will soon lose their ability to emit. Even moths several times bigger than it were not spared, and eventually they all became a spider's dish.

As a vibration sensor

Many cave spiders live in caves and catch their prey leisurely.

After they build their nests, they will skillfully arrange some spider silk on the passage of the hole, and then lurk in the hole to wait for the opportunity. When small animals accidentally touch these spider silk, the spider will immediately jump out of the cave and catch up quickly. This hunting method not only makes up for the shortcomings of spider's lack of endurance, but also makes spider's hunting more purposeful. If the vibration is too large, the spider will judge the size of its prey and decide whether to attack.

Make a clam-shell cave

In nature, spiders are very afraid of animals with huge systems. In order to protect themselves, they added an openable cover to the door of the cave.

Spiders bind a layer of deformed soil tightly together by secreting spider silk. After a long time, some short plants have grown on the cover, which is quite realistic.

Build a building

The rolling spider in Morocco can be said to be a master of architecture in the spider world. This kind of spider lives in the desert, so they stick sand with spider silk and build tall buildings in the bare desert.

If you touch their house, they will suddenly jump out. Then they will keep running in the desert with backflips, which is really interesting.

Summary: In fact, spider silk has many other uses. Some spiders will wrap nets around their hands to catch prey like fishing, and some spiders will pop up like angry birds to catch insects. However, many such amazing spiders have no names, and many spiders and even humans have not obtained their image data. This fact tells us that human's understanding of nature is far from enough, and there is still a long way to go for human to know and understand nature.
