Over 400 million years old, the only blue-blood creature on earth, able to save people, but unable to save himself

Speaking of blood-blue creatures, you’d think it was a movie clip from a sci-fi blockbuster.The screenwriter in order to attract the audience’s attention, and deliberately come up with a strange creature.But there are, in fact, such species on Earth.It is the only creature on earth with blue blood.We call it horseshoe crab.However, the existence of this creature is more dedication, because it has potential medical value, has been constantly sought by human beings, until one day the number of horseshoid crab declined sharply, some animal protectors began to cry for it.Such stories may sound chilling, but they are true.The horseshoe crab lived for more than 400 million years and saved countless people, but ultimately couldn’t save itself.Should we humans also turn our love to such a group of creatures who are silently dedicated to mankind?What kind of cooperative relationship should be maintained between man and other creatures in order to survive together without harming each other.What is limulus limulus is a Marine arthropod belonging to the order Caudatus of the class Postomata.It looked strange, like a giant crab, dark brown all over.What stands out is the rigid carapace that covers it.Horseshoe crab has a broad head and chest.Horseshoe crab is a four-eyed animal, with two compound eyes and two single eyes.Compound eyes in the side, the head of the breastplate has 0.5 mm of two small monoculars, they are next to each other, separated by a black line.Small eyes are highly sensitive to light, and each eye is composed of several small eyes.The horseshoe crab breathes by beating water rhythmically with its gill.Limulus feeding is mainly animal, often ingest some small crustaceans, or some annelids.As well as being a hunter, horseshoe crabs also act as prey to humans.Horseshoe crabs are often served as a delicacy on the human table.The earliest discovery of this kind of animal was in the Jin Dynasty.In his book Guang Zhi, Guo Yigong once mentioned horseshoe crab (limulus limulus), saying that this kind of animal looks like a defecate and walks with a female, but can’t live alone without a male.The medical value of limulus was mentioned by a famous pharmacist in Ming Dynasty in his book compendium of Materia Medica. At that time, people did not know much about limulus.The horseshoe crab looked a lot like the iron we use in our daily life today.But in the eyes of the ancient people, for this strange creature, the ancients would often sprout the idea of taking it as food to satisfy their hunger.Horseshoe crab meat is not safe, because it may cause a lot of skin allergies, even life-threatening in serious cases.But the true value of horseshoe crabs is not limited to cooking.The great value behind it is medical breakthroughs through its blood.In 1965, f. Pang, a zoologist at Johns Hopkins University in the United States, published a paper on the link between horseshoe crabs and bacterial diseases.Once the paper was published, it attracted attention from all walks of life.People pay attention to horseshoe crab from the original simple food, to medical functional thinking.Limulus blood is blue, why can appear blue blood?The researchers found a particular type of copper ion in horseshoe crab blood that is responsible for its blue color.The blue blood extract is known to help patients quickly detect the presence of late-stage changes in their internal tissues caused by bacterial infections.Because of its unique properties, blue limulus blood is also used by researchers to monitor toxins during medical processing.Blue blood, which has a higher copper content, freezes instantly when it encounters bacteria.The reagent made from horseshoe crab blood can be used in medicine to determine whether a patient has infected bacteria or not.Helping medical workers save valuable time in saving lives.Horseshoe crab is on the verge of extinction, however, horseshoe crab can save thousands of people, but can not save themselves.Due to the increasing demand for horseshoe crabs in other fields such as medicine, the number of horseshoe crabs under normal growth cycle can no longer meet the needs of human beings in all aspects.So the species is facing the possibility of extinction.Human science and technology are not yet able to give precise results as to whether they can prolong the lives of other species.Horseshoe crab, still can accompany human to continue to walk a long way, no one can know.Human beings greedily enjoy limited resources.But nature’s bounty will eventually run out.What can we do?What should we do?Such questions are questions that people need to think about.We have expanded the possibilities of living things within the scope of application, but we have also increased the rate at which species disappear, which cannot be explained in terms of specific gains and losses.Will dying species give rise to new life forms?The answer may be no, so it is especially important to use resources wisely and protect species in a scientific manner.Limulus crab is one of many creatures endowed by nature to human beings. The size of living space of those creatures ignored by us will also indirectly affect the future of human beings.Those creatures that have not been protected in time by human beings are constantly being exploited and exploited.The growth cycle of such organisms is prolonged and their numbers are reduced, resulting in impaired balance of the biological chain.We are used to judging the existence of a species by its value.Biodiversity itself has indirect value, direct value and existential value.These values create immeasurable use value from virtually, thus accumulating a certain amount of capital.Lizards have medical equivalents Lizards are small reptiles, and one of the smaller species is called the Flying lizard. It’s flat and small, but it has a long tail.The spotted flying lizard is mainly distributed in Yunnan, Xizang, Hainan and other places in China.It lives mainly in tropical rainforests, is lithe, aggressive and likes to cling to tree trunks, mainly foraging for insects.Like horseshoe crab, the spotted flying lizard is also a member of the biological diversity.But the smaller, spotted lizards also have medical value.The flying lizard is used flexibly in clinical practice by medical personnel.Can be used to treat the symptoms of body fever caused by external wind heat.Woodpeckers – “doctors of the forest” woodpeckers – sooners of the air.The way they exist in nature is also a magical start.Unlike people, woodpeckers are more dedicated to the care of trees. Woodpeckers are always able to take out the borers from the trunks of trees and help remove the pests that affect their healthy growth.In addition, the marks left by woodpeckers can be used as indicators of deforestation.Perhaps even the woodpecker himself has not found that he is also a little hero of the ecology of all things, every short stay after a tired flight, for the whole nature, is a gift, inadvertently, to help the survival rate of other vegetation.These creatures seem ordinary, but have indirect value. Their survival opens up more life channels for human beings and other species.Use one kind of life to help another kind of life to live better.Such creatures are found everywhere in nature and will not be described here.The horseshoe crab, the white lizard, and the woodpecker are all invisible devotees who silently help create more value for the biosphere.We should gradually realize that each individual in the great biological chain has its own unique value.Those species that bring convenience to mankind, they should not be dismissed lightly.We should, in turn, help these creatures and sustain their offspring.Start from the protection of nature, not excessive consumption, to provide better biological growth, essential, material basis and living space.Only in this way can life in the universe be kept healthy.Because the absence of any one species, for the whole chain of diversity, is a disruption of balance.This situation, if left unchecked, will have all sorts of destabilizing effects on the world of the future.Learning to live in harmony with multiple lives will become the theme of The Times.Every living thing has its own reason for being, each of them, in a way that sets them apart from the rest.It is necessary to learn to respect different lives and take better care of nature.
