What kind of monster is it, with blue blood, that has been alive on Earth for 400 million years?

This monster is the horseshoe crab, its blood is blue, and its vitality is tenacious, and it has lived for more than 400 million years.

The horseshoe crab, a creature in the ocean, has the only blue blood in the world, and the value of the horseshoe crab blood is very high, and every year the horseshoe crab is caught and carried out"Forced blood donation"。The horseshoe crab has become an endangered species.

This creature is called horseshoe crab, and this creature has lived on the earth for hundreds of millions of years, has the name of a living fossil, and its blood is also blue.

The only creature with blue blood lived for 400 million years and saved tens of thousands of people but couldn't save itself.

One of the most unique creatures in the world is its blood, which can be described as "priceless". What's special is that its blood isn't red, it's blue. This is the horseshoe crab that lives in the ocean.

It is a creature with a small mass and volume, and it looks very similar to a soft-shelled turtle from the outside!

Since 1956, humans have been capturing horseshoe crabs and bringing them to laboratories, after discovering that the color of horseshoe crabs' blood can kill many bacteria in the ocean. Scientists have found that horseshoe crabs' blood seems to be unusually sensitive to bacteria. Scientists then spent 30 years making the blood of horseshoe crabs into reagents that could be used to detect bacterial toxins and so on.

But because of the high cost of farming horseshoe crabs, scientists prefer to catch them directly from the ocean, which makes horseshoe crabs live on the earth for more than 400 million years and have escaped mass extinctions again and again, but in the end the horseshoe crabs are still not strong enough to control their own destiny!

It is not easy for the horseshoe crab to live to this day, and the horseshoe crab certainly did not expect that it would not become extinct in the ecological and climatic changes in nature, and it would be about to perish in the hands of humans. Since the blood of horseshoe crabs is worth more than 100,000 yuan per milliliter, 100,000 of them are caught in the ocean every year and bled in the laboratory. Although some of the blood is released, scientists will continue to release the horseshoe crabs back into the ocean, but the horseshoe crabs have been collected because the blood has been collected.

The body will be abnormally weak, and when you return to the ocean, you can easily be caught by other creatures as prey. The horseshoe crab is now one of the most endangered species in the ocean.

Another reason is that although an adult horseshoe crab ovulates more than 90,000 every year, less than 10,000 horseshoe crabs survive and grow. The 10,000 horseshoe crabs are also likely to be reduced to the plates of other marine life, which further encourages the horseshoe crabs to eventually disappear from the earth one day. Nowadays, the demand for LAL reagents is very large, and many large pharmaceutical companies are constantly catching LAL in the ocean.

It also allows many people to seek business opportunities from it and hunt and kill horseshoe crabs privately. This has reduced the number to less than 10% in just half a century.

Ren is horseshoe crab himself definitely didn't expect his ending to be like this, the so-called success is also blue blood, defeat is also blue blood! It allowed the horseshoe crab to survive from the extreme living environment of the ocean, and also saved countless people, but in the end it could not save itself, I wonder what everyone thinks about this?

The only "blue blood" animal on earth, it has survived for 400 million years and its appearance has never changed!

Because humans discovered its use, they fished it aggressively, leading to the extinction of their populations.

There is a creature in the world, its blood ** is very high, it is because the blood of this creature is not red, but blue, this creature is the horseshoe crab that lives in the ocean, this is a creature of little mass, and from the appearance of the soft-shelled turtle is very similar, in the 50s of the last century, human beings began to catch horseshoe crabs, and brought the horseshoe crab to the laboratory, found that the blood of horseshoe crabs can kill many bacteria in the ocean, scientists have studied the blood of horseshoe crabs, It was discovered that the blood of horseshoe crabs is very sensitive to bacteria, and scientists later spent 30 years making the blood of horseshoe crabs into reagents, which were then used to detect bacteria.

But because it takes a lot of cost to breed horseshoe crabs, so there is no way, scientists go directly from the ocean to catch horseshoe crabs, although horseshoe crabs have lived on the earth for 400 million years, and have experienced many species extinctions, but still have not escaped the clutches of human beings, to know that horseshoe crabs can live to the present is not easy to do, to know that horseshoe crabs have experienced mass extinctions, but in today's highly developed human civilization, I did not expect horseshoe crabs to be buried in the hands of humans.

Because the blood of horseshoe crabs is worth 100,000 yuan per milliliter, every year there will be tens of thousands of horseshoe crabs caught by scientists, caught in the laboratory to bleed, although it is said that after a part of the blood, horseshoe crabs will be sent to the ocean by scientists, but you know, because the horseshoe crab has been collected blood body has become very weak, and after going to the ocean, it is easy to be used as prey by other organisms, at present, horseshoe crab has become one of the endangered species, and the horseshoe crab itself ovulates 90,000 every year, but the horseshoe crab that successfully survives and grows up is less than 10,000.

And these 10,000 horseshoe crabs are also very likely to become food for other creatures in the ocean, which makes the number of horseshoe crabs less and less, and one day may disappear on the earth, at present, human beings have a very large demand for horseshoe crabs, and many drug companies are constantly going to the ocean to catch horseshoe crabs, which also makes many people see business opportunities from it, and go to the sea to hunt horseshoe crabs privately, which leads to a large part of the survival of horseshoe crabs compared with before.

Although the blood of horseshoe crabs is very valuable for scientific research, this is not an excuse for humans to catch and kill horseshoe crabs wantonly, even if its blood is blue and its blood is valuable, but considering the diversity of the entire species, humans should not be too selfish. But in the face of money, no human being is not selfish, even if the crazy fishing of horseshoe crabs in the future will make the horseshoe crabs extinct, but human beings still only want immediate benefits.

Because this blue-blooded creature can use blood as a medical drug solvent to treat and treat tens of thousands of people, they are already scarce, and with this function, humans will wipe them out, so they can't save themselves from being killed by humans.

It is a horseshoe crab because of their low reproductive capacity and the fact that they have been hunted by a lot of humans, so they are unable to save themselves.

Horseshoe crab. The first thing that attracts the most attention of this creature is its blood color, after all, the blood color of most creatures on the earth is still reddish, like blue-blooded creatures are indeed relatively rare, and the living environment of this creature is on the coast or in the mud with water, usually in Asia and the east coast of North America.

The horseshoe crab is a very old animal, it has a history much earlier than the appearance of humans, and it is even older than the extinct dinosaurs. Because it evolved from a trilobite in the Cambrian period, it is more than 400 million years old.
