Insects are the most species in the world and the most widely distributed animals, almost occupyingEvery corner of the land ecosystem.About 480 million years ago, Okota, the ancestors of insects successfully boarded the land from the ocean, and differentiated on land into a highly diversified group.But do you know?A few insects have chosen a difficult path -return to the ocean, and the sea -tadpole insects are one of the best.
The living environment of the Insects of the Seae Family, they are hidden in this reef"> (Figure:" Knowledge is Power "magazine)
p> Sea taxi Sea CycThe rare strict sea birth group lives only in the ocean throughout his life, mainly distributed in tropical waters in the Pacific and Indian Ocean.There are scarce types of insects in the sea. At present, there are 13 types of insects in the world.In 2019, a new type of sea -cricket family insect was discovered in the sea of Antelope Reef in the Xisha Islands in Sansha Islands in Sansha City, Hainan Province, named it antelope reef seafood. The adults of the sea -soup insects are only 3 to 4 mm long, wingsless, mostly black, but the body surface is covered with white water -refusted hair (can make insects that can make insectsThe body is wet, and it can help them keep water). Most of them prey on small nodular animals (the largest species of animal worlds, with a few pipes -a polysaccharide -containing polysaccharide, which is the secretion of leather cells -Exotic skeletal, symmetrical, segments left and right in the body, attached limbs are also divided into sections, such as shrimp, crabs, spiders, crickets, etc.), such as other Haishengli insects (sea tadpoles, 黾 [mǐn] 蝽 family, wide shoulders, wide shoulders, wide shoulders, wide shouldersHeadaica, etc.), bomb tapeworm (small wingless insect, commonly known as jumping worm, will release a small organ in the back of the body when it is shocked, bounce into the air), hook shrimp (a small type of crustacean), beetle, etc. Male Antelope Reef Hydra (source: "Knowledge is Power" magazine) Although the worm is only a few millimeters, researchers have a way to distinguish between the family of male and female.From the appearance point of view, male individuals are usually larger, and some individuals still have very strong and stabbing forefoot; although female individuals are small, the forefoot does not evolve special structures and functions, but there is a "Y" -shaped pattern on the back. Female Antelope Reef Hydra (source: "Knowledge is Power" magazine) The life activity of the sea -ray family insects is closely related to the coral reef, so it is also called "the glideer of the coral reef sea".During the tide, they quickly shuttled in the gap between coral reefs, or stayed on the floating objects on the sea. The last age nymphs (the younger period of the perverted insect, the body part of the organs has not yet developed) and adults can even be drawn to the tide tide to the tide tideBelt (along the coast coast coast area between the daily rising organs and the low tide line) is far away.Air breathing. The long-sized abandoned ropes floating on the coral reef, the sea-cricket family insects are hidden in it (source: "Knowledge is power"Magazine) The small bug BigCourage The Trinity (the first period of the middle generation, from 250 million to 205 million years).It caused one of the five major biological clusters in geological history -one of the extinction of the five major biological clusters -the end of the three -stack of biological extinction, and the entire earth was shrouded in the huge ecological disaster caused by volcanic eruption for a long time.The coral reef system has also suffered a heavy blow, and its recovery process may continue until the Jurassic (the second in the middle of the middle generation, 205 million to 137 million years). Recently, after research on the genome of the Haiju family insects, scientific researchers found that in the early days of Jurassic, about 192 million years ago, Slowly grasped the tidal law of the ocean and adapted to the severe living environment of the beach. Among other pimples that are closely related to the climax insects, some groups also adapt to the entrance, mangroves, and tide in their respective evolutionary process, respectively.Different marine habitats such as interstitial belt and broad ocean noodles (the total of the spatial scope and environmental conditions of biological survival), each has gone to the road of adventure returning to the ocean.However, compared with these insects, the origin of the Seaechi family insects is likely to be the earliest "warrior" to the earliest successful return to the typical marine environment. Evolution!Towards the sea In order to adapt to the marine environment, there are many efforts to adapt to the marine environment.They minus the age of the nymph (the time experienced between the two adjacent molting) from 5 to 4. In order to avoid the hunting of the predator, it uses a more fine and smart exercise method. The 4-year-old period of the Sea Cycles Insects "Power" magazine) In addition to habit, life cycle, exercise method, etc., scientific researchers have found that the number of genes of many of them has decreased significantly.The molting cycle and the genes of flying -these changes happen to correspond to the decrease in its nymph period and the characteristics of wingsless. The eggs of the sea of the sea (picture source: "Knowledge is Power" magazine) In addition, there are still many microorganisms in their intestine. There are many microorganisms, and the sea -raye insects and them help each other in various metabolic pathways such as fatty acid synthesis and degradation.It played a very important role. Although they are so hard to survive, the habitat suitable for the survival of the sea -mortar insects is still very narrow. Some species are only distributed on an isolated island.Discover traces.This means that their living environment is relatively fragile, and if the habitat is destroyed in a small area, they will face the risk of extinction. Today, with the rise of global climate warming and the rise of the sea level, their habitat environment is changing silently.The distribution of insects in the sea of the sea is very closely related to the cycle of the ocean flow. It is studied for it and can find the evolutionary law of marine biological geography.In addition, its existence has a very important instructions for the ecological environment. Therefore, only by protecting the marine environment and maintaining the homeland where marine life depends on can it be made in front of everyone. waves, salt, osmotic pressure, no plant ... Over the years, scientific researchers have explained why insects are unwilling to get involved in the ocean, but there are still small insects in the ocean in the ocean, but there are still small insects in the ocean.Traveling, there are the secrets of evolution in hundreds of millions of years hidden in the body.
