There is a creature in the world whose blood is very expensive because the blood of this creature is not red, but blue. This creature is the horseshoe crab living in the ocean. This is a creature with a small mass, and it looks very similar to a soft-shell turtle in appearance. In the 1950s, humans began to capture horseshoe crabs and brought them to the laboratory. They found that the blood of horseshoe crabs can kill people in the ocean. Scientists studied the blood of horseshoe crabs and found that the blood of horseshoe crabs is very sensitive to bacteria. Later, scientists spent 30 years making reagents from the blood of horseshoe crabs to detect bacteria.

But because breeding horseshoe crabs costs a lot of money, there is no way. Scientists capture horseshoe crabs directly from the ocean, even though horseshoe crabs have lived on the earth for 400 million years and have experienced a lot. times of mass extinction of species, but it still has not escaped the claws of mankind. It is very difficult to survive until now. You must know that horseshoe crabs have experienced mass extinction of species. However, in today's highly developed human civilization , I didn’t expect that the horseshoe crab would also die in the hands of humans.

Because the blood of horseshoe crabs is worth 100,000 yuan per milliliter, tens of thousands of horseshoe crabs are captured by scientists every year and taken to the laboratory for bleeding. Although after part of the blood is drained, the horseshoe crabs will still be Scientists sent the horseshoe crab to the ocean, but you must know that because the blood of the horseshoe crab is collected, the body becomes very weak, and after arriving in the ocean, it is easily regarded as prey by other creatures. Currently, the horseshoe crab has become one of the endangered species, and the horseshoe crab itself will die every year. 90,000 horseshoe crabs ovulate, but less than 10,000 horseshoe crabs successfully survive and grow up.

And these 10,000 horseshoe crabs are very likely to become food for other creatures in the ocean, which makes the number of horseshoe crabs less and less, and may one day disappear from the earth. At present, humans The demand for the deeds of horseshoe crabs is very high, and many pharmaceutical companies are constantly going to the ocean to capture horseshoe crabs. This also allows many people to see business opportunities and go to the sea to hunt and kill horseshoe crabs privately. This has led to the current survival of horseshoe crabs. The volume has decreased significantly compared to before.

Although the blood of horseshoe crabs is of great scientific research value, this does not become an excuse for humans to catch and kill horseshoe crabs wantonly. Even if its blood is blue and its blood is priceless, we must consider Given the diversity of the entire species, humans cannot be too selfish. But in the face of money, no human being is unselfish. Even if the crazy fishing of horseshoe crabs in the future will make horseshoe crabs extinct, humans will still only pursue immediate interests.
