Who am I? Where am I? Who are my ancestors? These doubts have puzzled this distinctive scorpion since birth. Waking up at night (scorpions come out of the night), the scorpion asks the other scorpions around him (the scorpions live in groups), and they shake their heads and say, "It's late at night, it's time for us to go and find food." "Well, I'll find the truth myself," so the scorpion embarked on a path to its roots.
In the darkness of the night, the scorpion moves forward carefully, in addition to fearing encountering more ferocious beasts, it also has to worry about other scorpion populations, because different nests of scorpions often kill each other. Luckily, there was no danger along the way, and even subdued a small insect with his powerful pliers and a chele needle in his tail and abdomen.
After eating and drinking, it continued on its way, and it walked toward the forest, and there was a sound from the "rustling" side, and it turned its head to see a spider. It seemed that a fierce battle was about to take place, and the scorpion was ready for battle, and it was holding its own poisonous claw needle high, ready to attack. But the spider did not want to fight, but told the scorpion that in fact, the two of them were close relatives. But this look is not at all like ah, the spider has no pliers and no sectional abdominal structure.
"Don't worry, let's see if your body is made up of two sections." The scorpions found that this was indeed the case, and their heads and thoraxes were all in the front and the back was another whole. And the scorpion found that it and the spider's feet are only in the front part, and the back part of the abdomen is without feet, but people may have some misunderstandings when they usually lie on the ground. "This is the arachnid body structure," the spider said.
It seems that it is a step closer to the truth, and scorpions belong to the arachnid order. At this time, the spider called to the other animals of the arachnid order, the whip scorpion, which looked very similar to the scorpion, but the whip scorpion had a tail whisker on its abdomen, and the whip scorpion also told the scorpion that this tail whisker was left by their common ancestor, the clawed limbs.
Knowing this, the scorpion continued to walk. At the edge of a lake, the scorpion seemed to see his accomplice, but his eyesight was not good, so the scorpion had the courage to go closer, it turned out that it was not the same kind, it was a large-headed crayfish. The scorpion looked at the two pliers of the crayfish, then at his own two pliers, and asked, "Crayfish, are you my ancestor, are you a chelating animal?" "
"No, the relationship between scorpions and lobsters is far away." Crayfish prefer to live in streams, swamps, and some wetlands and lakes with low water bodies, while scorpions prefer tides rather than wetness, preferring shady environments and cave life. In terms of relationship, they mostly belong to the same arthropod phylum, but the arthropod phylum is the largest phylum in the animal kingdom, with 1.2 million animal species. The scorpion and the crayfish belong to different subphyla in the subphylum they are divided into in the first part, the scorpion is the claw subphylum, and the crayfish is the crustacean subphyla.
Crayon subphylum
It really doesn't matter, but it seems that all mention the crayon subphylum, and it seems that the ancestor of the scorpion was the animal of the crayon subphylum.
Crayon subphylum once lived in the ocean is the dominant existence, and the ancestor of the scorpion is the famous crayon subphylum giant feathered crab in the Clilian period 430 million years ago, according to scientists' deduction, this animal can reach 2 meters in length, in order to better catch prey in the sea, their head and thorax limbs gradually evolved into pincers, which is the famous sea scorpion era, they ran amok in the ocean, randomly catching prey.
The good times did not last long, and jawed fish appeared, and the sea supremacy of the sea scorpion was lost. After losing their supremacy in the oceans, they are often chased by predators, from preying on others to being preyed upon today, how can the ancestors of the aggrieved scorpions bear it. So they decided to gradually land, so they became the first animals to land.
By the time they landed, they had perfectly evolved their whiskers into pincers, and their abdomen was already high. To get on land, they had to breathe the air of the land with their lungs, so they evolved the gills-like organs they used to breathe in the water into book lungs, and their appearance was not much different from the appearance of the scorpions we see today.
As the first animals to land, the natural environment on land allowed them to develop better, and many insects also developed large and fat. This is all a delicacy for the scorpion, its tail whiskers slowly become a chelating needle after landing, at first the claw needle is only to increase the scorpion's defense ability and relatively small attack, and later with its own development, in order to be able to better digest food, its claw needle can actually inject venom, which makes it easier for the scorpion to eat.
After using the claw needle all the time, the scorpion's venom glands developed, and the venom was initially only used to help digest it to be able to use as a deadly weapon against prey. Under the chemical weapon with powerful pliers and tail cheles, scorpions have risen again, this time they still live in populations, strong conditions and excellent teamwork and life, scorpions have become another overlord on land, insect nightmares.
Nowadays, the scorpion has become one of the five poisons of the jianghu by relying on its skilled poison-making technique, and even humans who encounter scorpions from the wild must be respected, and the root-seeking scorpion only learned that its ancestors were claw-limbed subphylums, and it may not know that its ancestors were once the overlords of the sea and had such a powerful background. But it also doesn't need to know how powerful the ancestors used to be, and now they are also one of the best beings in nature.
