Spiders are characters in horror films. It would seem, why be afraid of them? It creeps to itself and creeps, and quite quickly. They do not do evil to people, weave a web. And life is rejoicing. And you go, how much disgust is caused.
Meanwhile, the process of birth of spiders is very difficult. How are spiders born? We will talk about this in the article.
Master nest
More precisely, we do not make crafts, but the mother of spiders. These arthropods develop in the egg. His spider keeps safe in a cocoon.
But first things first. First, the future spider mother weaves a nest. Weaves a "substrate" under the eggs. It is a soft web. Eggs are laid on this web. And on top are covered with another layer of cobwebs. We get web pancakes with a filling in the form of eggs between them.
After the pancake is ready, the spider turns it into a cocoon. And attaches to the wall of the nest. In it, the eggs ripen, and the little spiders inside are preparing to be born.
Number of spiders
How many spiders are born at a time? Given that the clutch consists of a fairly large number of eggs, it is difficult to predict how many babies will see the light. A spider can weave one cocoon and lay 5 eggs in it. And he can work on several with a total number of eggs of about a thousand. This is extremely rare. Most often, the number of cocoons with clutches reaches 10. Now imagine that each of them has five eggs. And that means fifty baby spiders will be born.
Spider mom
Speaking about how spiders are born, one cannot fail to mention the "merits" of their mother. The spider is the guardian of her babies. She valiantly guards the cocoon, and if anyone dares to encroach on the treasure, death awaits him. During the time while the babies develop in the eggs, the spider loses weight greatly. After all, she does not go to herself for food. As a result, her abdomen contracts very strongly and becomes wrinkled. The spider often dies near the nest, without waiting for the hatching of children.
If the novice spiders in this world are lucky and they will find the mother alive, then there is no better guard. A mother is able to recognize her children by feeling them with pedipalps. And woe to that spider, which will be in the zone of her feelings. Drive out at best. Otherwise, it will kill. This is a threat to your beloved children.
Spider birth
How are spiders born? Let's start with how the baby develops. A spider lies in an egg, right on the yolk of the egg. And going in one pile. Before that, it was segmented. And then all his body parts - segments - merged together. And the spider began to resemble a normal arthropod creature: there is an abdomen, and eight legs, and a head that smoothly turns into a chest, with eight eyes.
So our baby grew up. The egg is crowded with him. This is where the egg shell bursts. Or the spider itself makes its way to the exit from it, breaking the shell. If the mother is alive and close, she will help the offspring to get out. If not, then sit the little ones in the remains of the shell and wait for the first molt. Little spiders are funny: they are bald and colorless. They themselves cannot eat and weave a web.
Further fate
Like spiders are born, they sit hungry if their mother is not around. The spider kids feeds the first time until they molt. And what about spider-orphans? They eat the yolk, which is prudently stocked in their abdomen. And patiently wait for the molt. Molted, discarded children's skin and acquired chitinous shell? Now we can learn to weave the web.
Rarely, one of the "kids" immediately leaves his egg. Most spider babies live in the remains of the shell for several months. And then they come out, and their ways with brothers and sisters diverge forever.
True, not all representatives do. Crosses, for example, are knocked together. And they bask in the sun for a long, long time. Only then they disperse. And tarantulas travel on their own mother. They climb onto her back and ride like that. When they grow up, the spider itself settles the offspring. Throws them in different places from the back. Why not drop everyone at once, will it be more fun together? And so as not to starve to death.
Speaking of food. What do little orphan spiders eat, except for the yolk? The yolk will end, but you want to eat. It sounds awful, but it’s the body of its own mother that feeds them. Climbing out of the shell, the kids discover a shriveled dead spider. Only they do not know that this is the mother in front of them. And they lash out with a brood of food. So the spider feeds its children after its own death.
You can see how spiders are born in the photo. The sight is not the most pleasant, but useful for educational purposes.
Conclusion
Flora and fauna are special worlds. With its subtleties and tricks. It would seem to whom it is interesting how spiders are born? Hatched and fled. And as it turned out, this is a whole complex system. Everything in it is provided by nature. And the spider mother makes a strong nest, and the food for the kids is already hidden in the egg. And they moult in the remains of the shell. Only when the youth is strong, does it go in search of their place of residence.
Do not be afraid of house spiders. They are harmless and not toxic. And to kill only because arthropods seem vile - why? They have their value in the ecological system.
