Some time ago, Xiaobian introduced the "overlord of the spider" - tarantula, and the missed friends can enter the home page of the "door worm" to find. Spiders are the "regulars" in everyone's life, and most of the time they will be "sacrificed" under everyone's fly shoots and slippers. At present, the world has found more than 40,000 kinds of spider species, in our country has also found more than 3,000 kinds, don't look at them annoying to be hunted down, most of the mosquitoes and flies in our home can be eliminated by them, and today Xiaobian wants to introduce for you to the extremely rare strange species of the spider world - The Richteropsis spider, let's come and increase the knowledge.

<h1 class= "pgc-h-arrow-right" > nature's masterpiece, the seal spider</h1>
The shape of the creature is strange, or gorgeous enough to make people fall in love, or ugly enough to be avoided. Most spiders look the same in everyone's eyes: eight legs, furry, highly poisonous, etc., and when they first saw the Richter-plated spider, scientists even thought it was a spider that was seriously injured and disabled. This creature was first discovered in the northern region of Thailand in 1901, and our country was discovered in Sichuan Province in 2000, and its shape also broke many people's understanding of the shape of spiders. The abdomen of the Richter-plated spider is like being cut off by a knife, forming a strange flat circle shape, and there are unknown lines on it, like a mysterious seal, so it is also called a seal spider, and even some netizens have given them a nickname called "spider seal".
Seal spiders are not the same way of hunting as other spiders, usually spiders are knotted webs to catch insects and other prey, and seal spiders especially like to dig holes, so the soft fields have become their favorite habitat, they are out hunting at night, lurking near the cave crouching point to ambush the prey, using the hair on their feet to feel the vibration of the ground when the prey walks, when the prey is close to them, and then jump out to bite the prey in an instant. Of course, the seal spider's prey is not only insects, but also some small frogs and small lizards passing by are often reduced to their rations.
<h1 class="pgc-h-arrow-right" > the story behind the seal spider</h1>
In fact, the seal spider also has an interesting name in China - money trapdoor spider, there is an interesting story behind it, because this spider especially likes to live in the soft soil of the farmland, so when the farmer found the seal spider in the process of ploughing the field, he thought he saw a large copper coin, and the farmer who saw the money eye was of course happy to think that he had picked up the treasure, so he picked it up by hand, and everyone can imagine when the farmer picked it up and found that it was a terrible spider. Since then, this extremely strange spider has been called "money trapdoor spider" because of this story.
As for why the seal spider grew into this virtue? What's the real difference between their weird ass? Since they don't have spider web defenses, the unique shape of the butt becomes their most powerful defensive weapon, and when it encounters an enemy, the seal spider will quickly run into the cave and block the hole with its butt. This unique shape of the ass is not simple, compared to other spiders' attack weapons, their butts can be said to be hard as iron. It may also be because of this unique defensive behavior that the seal spider will evolve into this unique shape.
<h1 class="pgc-h-arrow-right" > how rare the seal spider really is</h1>
Many experts will be particularly interested in the lines on their butts when they first see the seal spiders, and copy the pictures on their butts, and they did not expect to find similar graphics. At present, a total of seven kinds of seal spiders have been found in the world, and the seal pattern behind their butts is still different. This very special spider has high requirements for ambient temperature, and if the temperature is below 13 degrees, it cannot survive, which is an important reason why they are so rare and precious. Since 2000, fewer than 20 have been found in Sichuan, Fujian, And Zhejiang, China, making it the "rarest spider species." The farmer who found the seal spider in the first place could be regarded as having found the treasure.
< h1 class="pgc-h-arrow-right" > concluding remarks</h1>
Spiders have a history of more than 300 million years, living on Earth far earlier than humans, and the areas they live in are constantly being compressed and even extinct by humans. Although spiders are one of the five poisons, there are less than 30 kinds of poisonous spiders that can really threaten human life, so I hope that everyone will not see spiders and kill them, after all, they are also our natural "anti-mosquito machines".
