In our article we want to talk about spiders. With their numerous paws and eyes, they scare people. True, some still dare to keep them at home as a pet. However, scientists believe that there are quite interesting facts about spiders. In general, they are charming and amazing creatures.
Our attitude towards spiders
There are more than forty thousand different spiders in the world. Some of them live next to us in our homes. And we really do not know anything about these creatures. Of course, their appearance is not very attractive, but most of them did not deserve such a dismissive attitude towards them. They are completely safe for humans, and therefore you should not be afraid of them. Although there are poisonous species in the world, the bite of which is very dangerous for humans.
Interesting facts about spiders
So, we want to tell you some very interesting facts about these creatures that you probably don't know.
1. Spiders are helpful. Only one such creature kills about two thousand harmful insects a year that fall into its nets. Mostly spiders feed on flies and mosquitoes. We can say that they make a significant contribution to the fight against harmful insects.
2. In Italy, in the 15th and 16th centuries, there was a belief that a person who was bitten by a tarantula was overcome by madness. This species of spider lives exclusively in the south of the country. However, later scientists came to the conclusion that it was the tarantula that was completely safe. But the tarantula is a really poisonous and dangerous creature. However, it lives in completely different regions.
3. The largest spider in the world is the goliath. Imagine that it can reach thirty centimeters. He catches and eats birds, although he can also feast on amphibians, rodents, insects, snakes. Spider fibers are poisonous, which means they are dangerous to humans. But their venom is not lethal.
4. There is only one spider in the world - a vegetarian. This is Bagheera Kipling (this is the name of this species). The jumping spider eats the leaves of plants, especially loves the acacia. Sometimes it will eat ant larvae, but this is extremely rare.
5. Spiders live all over the world. Only in the cold of the Antarctic they do not live. This is due to very low temperatures. There are only spider crabs that are not arachnids. But the Arctic is inhabited by more than 1000 species of these creatures.
6. Everyone knows that spiders spin thread. However, not everyone knows that this thread is different in different species. The most durable silk thread is spun by Darwin's spider. It is so strong that it exceeds the strength of the material from which bulletproof vests are made.
7. The most poisonous is the banana spider, whichdangerous to humans. Its venom paralyzes muscles and the respiratory system. However, it does not always inject venom when it bites.
8. Spiders lay several thousand eggs at a time. However, not all newborn babies survive to adulthood. So, out of a hundred eggs, only one spider will grow.
Amazing abilities of spiders
Harvesters, which we often meet, outwardly very similar to arachnids, but do not belong to them.
Some varieties of spiders can jump very well. The distances they cover are impressive. During the jump, they still have time to unfold their silk thread, which gives them the opportunity to land accurately.
There are water spiders in the world. They can also live underwater. To stay there, the spider forms a bubble of air around itself, which allows it to breathe. It should be noted that it is very poisonous. But, fortunately, it is rare, and therefore does not pose a real threat to humans.
Discussing interesting facts about spiders, I would like to say that they have a very special blood, which becomes blue in the air. It is absolutely not similar to the blood of animals and people. In fact, spiders do not have a circulatory system and shelter in the usual sense. They have a hemolymph that provides communication between various organs. So the main substance of hemolymph is copper, which is why in the air, oxidizing, copper particles give such a blue color.
Are spiders edible?
Some arachnids are edible. In Asiathey are cooked and eaten. You can easily buy them in a restaurant or in the market. In Cambodia, for example, fried spider is considered a delicacy. They are served on the table as a delicacy, because there is delicious meat under the crust.

Sometimes spiders are kept in the house as a pet. Some varieties are quite large and are able to develop a decent speed of movement. Imagine that such a creature overcomes a little more than half a meter per second. It's just fantastic!
So what to do? Should spiders be feared, or should we just overcome disgust and treat them with due respect?
Scientists have long established that people are obsessed with fear of arachnids.

The cross spider got its name from the fact that on its back there are peculiar spots in the form of a cross. This creature is extremely dangerous and poisonous. Its bite without immediate medical attention can lead to the most irreparable consequences for human life.
Listing interesting facts about spiders, I would like to note that they are all different-sex creatures. As for the cross, the male dies after mating. But the female begins to prepare for the appearance of offspring. She spins a cocoon, which she wears on her back at first, and then hides in a secluded place. Her offspring are there.
Males at the beginning of their lives actively weave a web for food, and by the mating period they begin to roam in search of a mate. That's why they lose weight. In general, females perceive them as potential prey and may well eat them.
On the one hand, the cross is extremely dangerous for humans with its poison. But, on the other hand, there are benefits brought by these creatures. For example, its web has an antibacterial effect, it is used to heal and disinfect wounds.
