One liter of horseshoe's blood sold to 100,000, the new crown vaccine is not inseparable from it, what is the horseshoe crab?
The horseshoe crab is a magical ancient marine creature that knows that it still exists, but is called "living fossil", which attracts people's attention, not only it has survived on the earth for more than 400 million years, it has a unique appearance, and the unique blue blood also attracts attention.
【The Discovery of "Horseshoe Crab"】
Horseshoe crab, a national second-class protected animal, according to historical records, when the appearance of the horseshoe crab dinosaurs have not yet been born, the first appearance of the crab in the geological history period of the Paleozoic Devonian, primitive fish has just emerged.
According to the time calculation, the horseshoe crab has experienced two ice ages in these 400 million years, and its contemporaries "trilobites" have become living fossils. According to the history of biological evolution, organisms are either evolving or have become extinct, and only the crab has not changed its appearance from 400 million years ago to the present.

In ancient China, people discovered the medicinal value of horseshoe crab and applied it to medicine. According to the data, the whole body of the horseshoe crab can be medicated, like the tail of the horseshoe crab can be made into the tail charcoal, which can be used in patients with tuberculosis hemoptysis, gastric bleeding or direct external treatment of trauma bleeding.
The crab beads have a detoxifying and detoxifying effect and are often used when the throat is swollen and sore.

According to statistics, at least 500,000 healthy horseshoe crabs are caught every year and extracted from the blood in the body, but the world's more than seven billion people still cannot meet people's demand for horseshoe crabs, and the blood of horseshoe crabs is slowly pushed to the price of gold.
In 1956, F. Bang, a zoologist at Johns Hopkins University in the United States, published a paper called "A Bacterial Disease of Horseshoe Crab", which was when people really began to study horseshoe crabs and found that the unique blue-blooded horseshoe crabs had high scientific research value in medical treatment.
Horseshoe crabs have survived on Earth for more than 400 million years, in large part because of their blue blood, which has been found to build an immune system.
According to the "Chinese Pharmacopoeia", injectable antibiotics, glucose and vaccines must all be tested for bacterial endotoxins before they are listed, and now the market is now commonly used to detect endotoxins. In the modern medical and health system, in addition to the new crown vaccine, nine-valent and other daily injections, are inseparable from the horseshoe.
【 "Horseshoe crab" will be in a period 】
With the destruction of the natural ecological environment, humans have carried out a large number of arrests on it, resulting in the number of horseshoe crabs is getting smaller and smaller, and now the horseshoe crab has become a national second-level protected animal, people have begun to artificially breed horseshoe crabs, but the horseshoe crabs will return to the deep sea for hibernation in a certain season, so the difficulty of artificial breeding is very large, and there is a situation of "one liter of horseshoe's blood selling 100,000".
It carried through volcanic eruptions, through the ice age, through planetary impacts on the Earth, from birth to growth to take 15 years, and during this time the female crab has to go through 18 molting, males have to shed their shells 19 times; This species has lived on earth for more than 400 million years, but now it has not carried the claws of human beings, and the species is facing extinction.
According to a team led by Professor Robert Cowie of the Pacific Center for Biological Sciences at the University of Hawaii, "The sixth mass extinction has begun on land and appears to be increasingly likely to occur in freshwater." This time it was not caused by natural disasters, but more by human factors. ”
We should pay attention to the protection of living things, respect the diversity of species, and avoid the scene of "Maybe you don't care about the demise of any small species until a disaster suddenly comes and humans suffer their own consequences" as told in the documentary. #Epidemic #Vaccine# #动物 #
