How do you feel about light? No, no, no, I'm not talking about "Who says that standing in the light is not a hero" as sung in the children's song "The Lone Brave", nor is it a cartoon of a giant of light who "believes in the light" like Superman Diga. What I really want to talk about here is natural biology. Recently, there is light in the deep sea published by CITIC Publishing Group focuses on the luminous bodies in the ocean, giving readers a personal heroic author who explores the story of marine luminous organisms.

This book is a non-fiction popular reading about the study of marine life. But it also vaguely reflects the vivid style of storytelling to reflect such research results. For example, in the preface, the author talks about using magic to compare luminous creatures, which indicates that bioluminescence is not a rare secret strange thing in nature, but a most unforgettable and precious memory.

This popular science book about underwater illuminators introduces strawberry squid, flagellate, crystal jelly jellyfish, water hyacinth squid, bearded sea devil, shoulder lamp fish, green parrot snapper and velvet belly lantern shark. Fireflies, anemones, sea snow, American squid and so on.

In the first chapter, the author cited strawberry squid at the beginning, and analyzed the shape of this squid from its professional perspective, thus taking this as an example to illustrate that "if we want to build the visual ecology of the largest living space (ocean) on earth, we must understand the essence and function of eyes and bioluminescence at the same time". This is such a theoretical basis, which makes the author and his team lay a solid foundation for theory and practice in the following research. Later, in this chapter, the author explained his life experience, and why he dreamed of becoming a marine biologist since he was a child. It was because he had a childhood experience of loving fireflies, and the more direct fuse was her brief blindness caused by an accident, which made her feel special about light. So he overcame all difficulties and went deep into the study of marine luminous biology, making his own humble journey to explore the mystery of life for his own interest, and even more for mankind.

So in the second chapter, the author talked about the part that should have light, and listed the chemical substances of bioluminescence reaction, namely luciferin and luciferase. These findings were discovered by French biologist Dubois, which led human bioluminescence research into the modern stage. In the third chapter, the first flash is to take the toxic flagellate as an example of her formal marine luminous research. Although this luminous species is less than 40 microns in diameter, its light can penetrate several feet, which is the charm of such luminous research. Of course, it is worth noting that this poisonous flagellate is also the main reason for the formation of "red tide". It also shows that the harm of this creature to human beings is accompanied by 10 of the number of people killed by shark attacks. This naturally wants the world to be alert to the excessive complexity of such creatures and not to let the red tide harm mankind. In addition, the author has also made a precise study of flagellate, thus drawing a conclusion that the luminous behavior of flagellate is also a kind of defense ability, because some creatures always want to eat them, but as long as they shine, it means that they are poisonous and inedible. Therefore, copepods are far away from it. Natural luminescence is a defensive survival instinct for flagellate. In addition, the author went on to talk about the luminous function of Pyricularia fusiformis or a signal to help friends.

Of course, the author, as a submarine explorer and researcher, will also fish when she goes to the bottom of the sea at night, and she will return home with a full load. For example, she will catch glowing krill, jellyfish, pitcher fish, axe fish, and the giant fish that drags the net after that? ? ? ? Fish can be said to have a private party with luminous marine life and "rover". Interestingly, the author also introduced in detail the fish that is "alongside the rich woman"-giant male? ? ? ? Fish, how is this kind of fish "alongside"? So male? ? ? ? Fish will be in females? ? ? ? An eternal kiss is printed on the flank of the fish, and then the female's blood will flow into the male's body to provide food for him, and the male has been rewarded with sperm. This seemingly romantic love story is actually that male fish are just vampires and sperm bags.

In the star in the sea in the fourth chapter and the strange light in the fifth chapter, the author continued to dive deeply with the improved diving equipment and tools-"wasp" diving suit, which brought us to know the Pacific side wrist jellyfish and Pacific krill. In chapter 9, the "minefield" of bioluminescence is proved by practice, and the author explains that on earth, almost all natural light that illuminates life comes from two sources: the sun and bioluminescence. In the depths of the ocean without sunshine, countless strange creatures create the light of life in the dark. At the same time, it also introduces the high risk and arduousness of this kind of submarine research and exploration. Among them, the author also analyzes that there are four hidden dangers in the submersible: the submersible itself, the launching and recovery system, the diving place and the diver's quality. Even so, the author's analysis report not only provides valuable experience for future generations in exploring the ocean, but also reflects her noble sentiment of benefiting mankind.

In the dark story in Chapter 9, Link and Christopher died of carbon dioxide poisoning in the process of diving. It once again shows that such a journey of exploration is a long way to go. And dangerous. In addition to the above, there is another reason why the author wants such a record, which is to appeal to the society, especially the American authorities, to support and care more for this undersea exploration. Because in the plan B in chapter 10, the author takes that in 20 13 years, the United States spent only 23.7 million yuan on seabed exploration, while space exploration was 3.8 billion dollars. As both scientific research, the dilemma of "disparity between the rich and the poor" naturally reflects the author's dedication to the seabed exploration industry and his childlike heart for the benefit of mankind.

Later, in the language of light in chapter 11, the author introduced the firefly, which is a luminous Ostracoda, because they bring colorful ocean lights to human beings. Although this is beautiful, behind the beauty, we can also read about the destruction of human beings, which makes the light show eclipsed. For example, the author cited the firefly in Florida, which disappeared after a while. Here, the natural author is talking about the plight of marine life, such as plastic pollution, chemical pollution, eutrophication, overfishing, species invasion and other issues. The author's purpose is to appeal to human beings to love luminous bodies and marine life out of environmental awareness, so as to protect the earth and protect our own beautiful home.

On the edge of the map in chapter 12, we can still read the beautiful images of anemones and sea snow. It is also interesting here that the author also studies that the fecal particles of many marine organisms glow because the western skirts that help them decompose glow. This is the very attractive concept of luminous stool. This popular science book is very readable. What is interesting is the cannibalism mentioned in Chapter 14. The author once heard a friend say that the wild cats on the roof of his house will eat their newborn children in hunger, which is naturally a kind of cannibalism, and in the underwater world, the author also introduced in detail the situation that American squid kill and eat each other.

The author of this book is Edith Wade, an American doctor of neurobiology, oceanographer and marine biologist. Combining laboratory research and innovative technology, she is committed to discovering and observing deep-sea luminous creatures and exploring the significance of bioluminescence. She told us that the underwater world, which looks like a dark place, actually contains Gan Kun. In fact, it is the living space of luminous organisms, and that underwater space is naturally full of the fire of life. Here, we have not only read the general situation of the activities of submarine illuminators, but also read the hardships and high risks of submarine exploration industry, as well as the professionalism and tireless quality of employees in this industry to benefit people. At the same time, from the perspective of environmental protection, the author tells us that while enjoying such a beautiful undersea light show, we also call on people all over the world to support undersea exploration and protect the earth. Let's follow the author's "wasp" diving suit and visit those "rovers" that glow in the deep sea.
