No, no, there will still be people who misunderstand the "honest man" spider, right?
Usually everyone thinks that the spider is an extremely dangerous "insect", what is the joke of saying that it is an "honest person"? Don't worry, listen to me tell you the details.
In life, the spider is our neighbor, and you can find it everywhere. And whether in the countryside or in the city, these eight-legged little things live in the unknown corners, which will suddenly crawl past your eyes and quickly disappear, making you find that they are long gone after a short scream.
I've seen a joke on the Internet: if it appears in front of me, I can jump in a laser rain overnight...
However, for the well-informed friends who grew up in the countryside, encountering spiders has long been accustomed to. Even among these daring friends, there are people who see the protagonist of "Spider-Man" being bitten by a spider and gain incredible power after fantasizing: If there is such a spider that bites me, how good?!
Of course, in fact, spiders do not bring us any special abilities for two reasons: one is that Spider-Man itself is fictional; the other is that even if you are bitten by a mutant spider, you will not become Spider-Man if the elements in your body are incompatible with toxins.
To justify the name of the little spider, it turns out that we all misunderstood it.
Most people may think that spiders are ugly and terrible, and the first thing is to kill them all! In fact, spiders are not only beneficial insects, but also some spiders look cute and cute!
We have too many misconceptions about them!
Myth 1: Spiders are insects.
Insects have three parts: head, thorax and abdomen, while spiders have only two parts of head and chest, and spiders have four pairs of legs, while insects generally have only three pairs, so spiders have always belonged to the arthropod arachnoid order.
Misunderstanding two, spiders like to chase people, bite when they see people, and once they are bitten by highly poisonous spiders, the consequences are unimaginable.
Don't believe it, they never take the initiative to chase people, because humans are too big to be prey... And spiders are actually very timid, they will avoid humans as much as possible to reduce potential dangers.
The spider's venom wasn't as scary as we thought! Even if bitten by a reclusive spider (Loxosceles, a poisonous spider), 80% of the bitten people are actually not in serious trouble in the end, and even if they are bitten by the Black Widow spider, the probability of death is only 5%! They are not even as harmful to humans as mosquito bites or bee stings!
Some data show that in the 20th century, about 100 people were killed by spider bites, compared with about 1500 deaths due to jellyfish stings, and much more due to mosquitoes!
Myth three, spider eyes are very good eyesight, eat meat, will form a web.
The truth is that the spider's vision is really not bad, it can only be said that the more compound eyes they have, the higher the vision. And some spiders also eat plant vegetarian food, only about half of the spiders will form webs, and the rest about half will not! There are also spiders that do not all live alone, there are also some socials; blind spiders and camel spiders are not spiders and so on...
Who is the world's top predator?
Not humans, killer whales or tigers. The creatures that kill and consume the most prey each year are spiders of lower and mid-ecological niches. This is the conclusion of an enlightening study conducted by a Swiss spider scientist.
Everyone knows that there are many spiders on the earth, but how many may be rarely known to know more?
In fact, there are so many spiders that scientists unusually no longer use quantitative units to calculate like other species, but use weight units to weigh this species! Scientists estimate that there are about 25 million tons of spiders in the world, and they prey on 400 to 800 million tons of prey each year. Their prey is mostly insects, but occasionally frogs, lizards, fish, and even bats. By comparison, according to the Food and Agriculture Organization of the United Nations (FAO), humans consume about 400 million tons of meat and fish in a year. Whales eat about 280 to 500 million tonnes of seafood in a year.
Spiders have many uses, such as catching insects, predicting the weather, and so on.
Some people will say that even if spiders are not too much of a threat to humans, what is the use? Wouldn't it be better for humans to take care of themselves?
This question includes my thoughts, but many of the useful inventions of mankind are inspired by animals. For example bats, radars; bulletproof weapons, beetles; electronic frog eyes; dolphins, sonar; dragonflies, helicopters, etc... Small spiders are also beneficial to humans, and people invented man-made fibers based on spider silk, so that there are now many warm cotton wool products.
At the same time, spiders will weave webs in the summer to prey on mosquitoes and flies, and people can predict whether it will rain that day through the spider's web-knotting behavior. In some places, spiders are also used to deal with scorpion venom, and once someone is stung by a scorpion, they will use spiders to suck the scorpion away. Isn't such a cute creature an "honest man"? So if you have spiders in your house, stop thinking about killing them all, just gently dust them away.
