Let's see how many paws the spider has and how it uses them

Despite the fact that today we are surrounded by millionsspecies of all kinds of insects, both large and completely invisible to the eye, many people have absolutely no idea how these insects look really, that is, in an enlarged view. For example, about how many paws a spider has, children are not told either in kindergarten or in school, and in the future a person simply does not think about it. Therefore, the structure of the body of insects remains a mystery to many, and when you have to deal with some nuances of this kind, often a stupor begins. Well, let's try to understand now what the spider looks like, and what are the peculiarities of its numerous legs.

Brief anatomical theory

The answer to the question of how many paws a spider can havethere is only one: they have eight. This amount does not depend on the size of the insect, its type or location. It is worth noting that often, looking at the image of a spider, many number as many as ten paws, but these calculations are erroneous. Just people confuse pedipalps, which are located in the nose of the insect, with an additional pair of paws.

On the other hand, these two limbs spideruses in order to rake food, to search through the receptors that are located on them, the safest way to travel, and also to control the balance. But never such insects do not use pedipalps as auxiliary limbs for movement.

Why does the spider have so many legs?

If the information about how many paws the spider has,more or less familiar to many, the actions that this insect produces with their help are not known to everyone. First, let's take a look at what exactly all four pairs of legs represent, and then, on the basis of this, we will consider what it gives the insects.

Spiders are arthropod creatures, therefore,all their paws are some kind of tentacles. They are all possible receptors of smell, touch and many others. The spider's paws simultaneously perform the function of locomotion, recognition of danger, search for food and web weaving. Parent-arthropods with the help of their tentacles keep the cocoon, and if necessary, transfer it to another place. That is why spiders own such a large number of legs, which simultaneously serve them as hands, nose, vision and even the so-called "sixth sense."

A spider without a paw - the same full-fledged spider

Not so long ago an experiment was conducted in France,who proved that arthropods, which have lost one or two of their limbs, do not notice this loss. For this, in one container were planted full-bodied insects, which have all the legs. In another they found themselves to gather, which for some reason lost one or two legs. As a result, weaving the web, obtaining food and other life cycles arthropods in both containers performed the same.

The fact is that the back pair of paws is given to spidersas if in reserve. They use them in the event that they lose their front tentacles. By the way, this phenomenon occurs in nature too often, so you can easily find a spider at your dacha, who will own only seven or even six limbs.

The longer the paws, the more terrible the spider. Is it so?

Most of us have met such insects asSpiders with long paws, which are gray and move very, very quickly. Someone they terribly scare, for someone they seem to be specks of dust, which can easily be blown away. However, few people know that these arthropods are not spiders at all.

In science they are called "haymakers", and in the peoplethey are simply called "false-spiders". To recognize the haymaker and distinguish it from a spider is very simple. The first have a dissected abdomen, which almost completely merges with the cephalothorax. Spiders also have a holistic tummy, which is connected to the head with a thin membrane.

Conclusion

Knowing about how many paws the spider has, how heenjoys and what are the characteristics of their work, you can with less fear already look at these insects, realizing that they are not as terrible as it seems. And that in reality only those arthropods who live in the southern regions and have poison in their pedipalps can cause harm.
