Introduction of jellyfish
Jellyfish (jellyfish) is a kind of lower marine invertebrate zooplankton and carnivore. Taxonomically, it belongs to coelenterata (also known as Echinotheca) and Scyphozoa, with about 200 known species. Or species of Cubozoa, which used to be considered as an order of Cephalopods. The term jellyfish also refers to jellyfish-like (bell-shaped or dish-shaped) stinging animals in a broad sense, such as hydra jellyfish, tube jellyfish (including curly-tailed jellyfish), ctenophore jellyfish and sea urchin, which do not belong to algae-eating class. This kind of jellyfish can be divided into two types: free-swimming jellyfish and settled species (with stems attached to algae and other objects). Hydra-like species living in a fixed life constitute the order Stauromedusae. ?
morphological character
Jellyfish is shaped like a transparent umbrella with different diameters. The diameter of mother jellyfish's umbrella can reach 2 meters. There are some whisker-like strips on the edge of the umbrella, which are called tentacles. Some tentacles can be as long as 20 to 30 meters, which is equivalent to the length of a big whale. Jellyfish floating in the water extend long tentacles around them, and some jellyfish also have umbrellas with various patterns. In the blue ocean, these swimming jellyfish of different colors are very beautiful. Jellyfish appeared before dinosaurs, dating back to 650 million years ago. There are many kinds of jellyfish, about 250 species in the world, with diameters ranging from 10 cm to 100 cm, which are common in the oceans all over the world. There are about 8 common species in China, namely, Haiyue jellyfish, Baixia jellyfish, jellyfish, jellyfish and so on. People often classify them according to different umbrellas: some umbrellas emit silver light and are called silver jellyfish; Some umbrellas are like a monk's hat, called a monk's hat jellyfish; Some umbrellas are like white sails on a ship, called sail jellyfish; Some are like umbrellas, called umbrella jellyfish; Some umbrella-shaped bodies shine with rosy clouds, which are called chardonnay jellyfish ... most of them can only live for a few weeks, and some live for about a year. Some deep-sea jellyfish can live longer. The umbrella of ordinary jellyfish is not very big, only 20 ~ 30 cm long, but the giant umbrella of the larger summer jellyfish can reach 2 meters in diameter and the drooping tentacles can reach 20 ~ 30 meters. 1865, a jellyfish was washed ashore on the coast of Massachusetts, USA. Its umbrella is 2.28 meters in diameter and its antenna is 36 meters long. Pull the tentacles of this jellyfish apart. It is 74 meters long from the tip of one tentacle to the tip of the other. Therefore, it can be said that jellyfish is the longest animal in the world.
type
Jellyfish are hermaphroditic, with gonads close to the stomach pouch. Mature sperm flows into female jellyfish for fertilization. The fertilized egg develops into a larva and leaves the mother. After swimming in the water for a period of time, it sinks to the bottom of the sea to form larvae, and then becomes transverse cracks. Transverse fissure divides into multiple disc-shaped larvae, and then develops into jellyfish adults.
In recent years, sudden jellyfish swarms often appear in the seas around the world. Earlier, a large group of "Qian Yue jellyfish" appeared in Japanese waters. It is estimated that the Yangtze River valley in China is one of the sources of jellyfish in Qian Yue. With the overfishing of China's coastal industries, the number of fish competing with jellyfish for food has decreased, while plankton has increased, leading to the excessive reproduction of jellyfish. In addition, a series of abnormal rainstorms in the Yangtze River basin washed giant jellyfish into Japanese waters. In addition, the warming of ocean water temperature also accelerates the reproduction and growth of jellyfish.
Classification of jellyfish
Chrysaora species swim freely and are found in all oceans, including the common discoid animals drifting along the coastline. Most of them only live for a few weeks, and some live about 1 year. The diameter is generally 2 ~ 40 cm (1 ~ 16 inch), but some species are quite large, with a diameter of 2 meters (6.6 feet). The body composition is 99% water, because the main body of almost all species is made of jelly. Most of them prey on small animals with spiny filaments on their antennae. Some species filter microorganisms and plants in water. Like all echinoderms, the body is composed of endoderm, and there is an interlayer between them (connective tissue layer composed of colloidal substances). The mesothelium of jellyfish is thicker and more transparent than that of other echinoderms. ?
The life history of free-swimming true jellyfish can be divided into three periods. Immobilized hydra can reproduce asexually, split horizontally into larvae from top to bottom at the bowl mouth, and then split into discs, and each disc-shaped body length becomes an adult. Adults are male and female, but some species often change sex. Embryos formed by the combination of various sperm and eggs hatch into floating larvae in the digestive tract of adults, but some of them develop in seawater. After leaving their parents, the floating larvae are fixed and grow into new bowl-mouth larvae after a short period of so-called tube larvae. This life history is unique to Semaeostomeae, with about 50 species, mainly distributed in coastal areas, and some species are widely distributed. Such as Aurelia, Chrysaora and scarlet jellyfish (Tiburonia? Granrojo? Tiburoniinae), which is one of the three tentacleless jellyfish. ?
There are about 30 species of Guansuborder, mostly distributed in the deep sea, often reddish brown. The body is bell-shaped, defined by a deep annular groove between the middle part and the peripheral part of the body, and the peripheral part is divided into many wide petals. The edge tentacles are big and strong. There are several species in the larval stage, but the life history of most species is unknown. The crested jellyfish is the most primitive existing basin jellyfish, which may be the offspring of cone jellyfish. Conifer jellyfish flourished from1.800 million to 600 million years ago, and now only fossils are left. Several crested jellyfish have fixed branches and were once classified as a genus (Stephanoscyphus). ?
There are about 80 species of Rhizostoma. Mouth and wrist are wrinkled protrusions extending downward from the lower part of the body, which become roots and block the mouth, forming sponge-like areas for filtering food. No tentacles. The gel-like bell-shaped body is solid and has tumors. People with known life history have a typical benthic larval stage. Most species in this project are good at swimming; But some (such as 〔Cassiopea Aurelia〕) don't swim often, but put them upside down in tropical shallow water to let the natural photosynthetic algae get light. This species mainly lives in tropical to subtropical shallow waters in the Indian Ocean-Pacific Ocean, but Rhizostoma (also known as soccer jellyfish) is common in colder waters. Cotylorhiza is common in the Mediterranean. ?
Cruciferae (formerly known as Lucernariida) is not a true jellyfish in the strict sense, with about 30 species, stalks and fixed lives. Living mainly in cold water. Cup-shaped, with a fixed base handle and a mouth at the upper end. Diameter1~10cm (0.4 ~ 4 inches). There are 8 groups of antennae on the upper edge, which are four radial. Some species can be detached from the fixed point and can be re-fixed. They often prey on small marine animals and survive for several years. Direct development from larva to adult. Hydra stage is not obvious. ?
Cubaea has only one purpose, chironex fleckeri, which some biologists still classify as Potomalida. About 50 species are known. Although some species have a diameter of 25 cm (10 inch), most species have a diameter of 2 ~ 4 cm (1 ~ 2 inch). The body is spherical, but the side is square, so it is commonly called box jellyfish. Chironex and Chiropsalmus, commonly known as sea wasps, are widely distributed in Queensland to Malaya, and are highly toxic species, which will cause death within a few minutes after being stung. Up to now, the hydra in chironex fleckeri has not germinated, but has turned into an adult. ?
The main component of jellyfish body is water, which is composed of endoderm. There is a thick interlayer between the two layers, which is not only transparent, but also floating. When they are moving, they use the reflection of water in their bodies to move forward. Seen from a distance, they float fast in the water like a round umbrella. When jellyfish appear in groups at sea, they live closely together and float in the depths of the sea as a whole, which is very spectacular. The waves are like snow, and the blue sea is dotted with many beautiful umbrellas, flashing light green or blue-purple light, and some have rainbow-like halos. Many jellyfish glow. The slender tentacles spread out around and floated with them. The color and swimming posture are beautiful. There is a special gland in the umbrella of jellyfish, which can release carbon monoxide and expand the umbrella. When a jellyfish encounters an enemy or a big storm, it will automatically release gas and sink to the bottom of the sea. After the sea is calm, it only takes a few minutes to generate gas to make itself swell and float. When the ctenophore swims in the sea, the eight meridian tubes can emit blue light, and when it emits light, the ctenophore becomes a dazzling colored ball; There are several parallel bands of light around and in the middle of jellyfish. When it swims, the light band swings with the waves, which is very beautiful. Jellyfish glow through a wonderful protein called Aquimine. When this protein is mixed with calcium ions, it will emit strong blue light. The more amount of esquimine in jellyfish, the stronger the light it emits. Each jellyfish contains only 50 micrograms of this substance on average.
Although jellyfish are beautiful and docile, they are actually fierce. Under the umbrella, those slender tentacles are its digestive organs and weapons. The tentacles are covered with stinging cells, which can shoot venom like poisonous silk. After being stung, the prey will soon be paralyzed and die. The tentacles will hold these prey tightly, retract them and suck them with corals under the umbrella. Every coral can secrete enzymes to rapidly decompose protein in its prey. Because jellyfish have no respiratory organs and circulatory system, only primitive digestive organs, so the captured food is immediately digested and absorbed in the lumen. On a hot summer day, when we are swimming in the seaside tide, sometimes we suddenly feel a stabbing pain in our chest, back or limbs, as if we had been whipped. The jellyfish must be stabbing people again. But if you are stung by a jellyfish, you will only feel burning pain and redness. As long as you apply anti-inflammatory drugs or vinegar, you can reduce swelling and relieve pain in a few days. However, in the ocean from Malaysia to Australia, there are two species called sea bee jellyfish (box jellyfish) and hand-dragging jellyfish, which secrete very toxic substances. If stung by them, they will die of breathing difficulties within a few minutes, so they are also called killer jellyfish. Therefore, when you are stabbed by jellyfish and have difficulty breathing, you should immediately give artificial respiration or inject cardiotonic, and you must not be careless to avoid accidents. Once a jellyfish meets its prey, it will never let it go easily. But like rhinoceroses and birds that clean up parasites, jellyfish have their own companions. It is a small herding fish, only 7 cm long. It can swim freely between the tentacles of jellyfish, but it is not afraid at all. When a big fish comes, the small shepherd fish will swim among the tentacles under the giant umbrella as a safe "refuge", using the device of jellyfish stinging cells to cleverly avoid the enemy's attack. Sometimes, small shepherds can even lure big fish into the hunting range of jellyfish to kill them and let them eat the leftovers left by jellyfish. So why don't the stinging cells on the tentacles of jellyfish hurt the sheepdog? This is because the little sheepdog is flexible, can skillfully avoid poisonous silk, and is not easy to get hurt, but it is only accidental and accidental to die under poisonous silk. Jellyfish and small herding fish were born together and used each other. Jellyfish "protected" the small shepherd fish, and the small shepherd fish swallowed the small creatures that lived in the jellyfish.
Powerful and deadly jellyfish also have natural enemies. There is a kind of turtle that can freely shuttle through jellyfish, easily break their touch with their mouths, so that it can only roll up and down, and finally lose its resistance and become a "good meal" for turtles.
There is a small ball on the thin handle in the middle of the jellyfish tentacles, and there is a small auditory stone inside, which is the "ear" of the jellyfish. Infrasound waves generated by the friction between waves and air hit the auditory stone, stimulating the surrounding nerve receptors, so that jellyfish can get information more than ten hours before the storm warning, so they seem to have been ordered to disappear from the sea at once. Scientists tried to simulate the sound transmission organs of jellyfish and found that they could detect the information of ocean storms 15 hours ago.
Jellyfish is a kind of lower coelenterate, but its lineage is enviable. Jellyfish give birth to small jellyfish. Although the small jellyfish can live independently, it seems that there is a deep affection between parents and children, so the small jellyfish is attached to the jellyfish. Soon after, the little jellyfish gave birth to their grandchildren's jellyfish, and they are closely related to each other.
The largest Arctic cyanobacteria jellyfish is the Arctic cyanobacteria jellyfish distributed in the Atlantic Ocean. Its canopy can reach 2~5 meters in diameter, and there should be 8 groups of tentacles on the umbrella, each group has about 150. Each tentacle stretches more than 40 meters, and it can shrink to only one tenth of its original length in one second. There are stinging cells on the tentacles, which can dig out stinging filaments and radiate toxins. When the tentacles are fully extended, it is like laying a tight encirclement, and the net cover can reach 500 square meters. Any fierce animal, once caught in a net, will surely give in easily. 1870, an arctic jellyfish was washed into Massachusetts bay, USA. Its umbrella is 2.28 meters in diameter and its antenna is 36.5 meters long. The smallest jellyfish is only 12 mm long.
Box jellyfish?
Box jellyfish, commonly known as sea wasps, is named after being box-shaped after a full meal. It is one of the top ten poisonous creatures in the world. The most poisonous jellyfish is the Australian box jellyfish, which is toxic enough to kill 60 people. The toxicity of this marine life can kill people in three minutes. But there is no danger in wearing underwater tights. Every year? 1 1? From 1 month to the following year? 3? This month is their active season. Jellyfish can weigh up to two kilograms, and their tentacles can be as long as three meters. Box jellyfish has dozens of tentacles as long as three meters and about 5000 stinging cells. These stinging cells can pierce the victim's skin and release venom. ? This is the most evolved jellyfish known at present. They can feel the existence of objects in water through the difference of light brightness. Box jellyfish are translucent in water and difficult to detect. They will escape the storm by retreating to the bottom of the sea. ?
Peach blossom jellyfish (peach blossom jellyfish? sowerbyi)
Peach blossom fish, also known as peach blossom fish, is the lowest creature on earth. Peach blossom jellyfish is the most primitive and lowest invertebrate coelenterate, which has existed for 650 million years, hundreds of millions of years before dinosaurs. It is known as a "living fossil" in the study of biological evolution, and its unique genes are of great significance to modern genetic engineering research. Peach blossom jellyfish have extremely high requirements for the living environment, the water quality cannot be polluted, and the living body is scarce, so it is extremely difficult to make specimens. The "extremely dangerous creature" listed by the state as the highest level in the world is also known as the "giant panda in the water". ?
Peach blossom jellyfish, commonly known as "peach blossom fish" and "parachute fish". Hydra jellyfish, transparent, slightly milky white, thumb-sized, with a diameter of about 0. 1 cm to 1 cm and 256 tentacles, can be divided into seven grades according to their length. They float and sink in the water through the contraction of the umbrella and the up-and-down movement of the tentacles. Hydra is underdeveloped, only 2 mm high and has no tentacles. Fresh water production. Worldwide distribution, China has been found in Sichuan, Zhejiang, Hubei and Hanzhong, Shaanxi. ?
Peach Blossom Jellyfish belongs to Echinotheca, Hydra, Freshwater Jellyfish and Jellyfish. The body of the peach blossom jellyfish consists of only two layers of cells, and there is a cavity in the body, which is the place where food is digested and absorbed, which is equivalent to the intestines of other animals and belongs to coelenterates. Peach blossom jellyfish is crystal clear, swimming around in the water, and its posture is like peach blossom petals floating on the water. The life history of peach jellyfish is the alternation of asexual reproduction and sexual reproduction. Newt (the "childhood" of jellyfish) has extremely low requirements for the environment, but once the jellyfish is isolated, it has high requirements for the environment and water quality. When the environment adapts, salamanders naturally separate jellyfish; When the environment is unfavorable, salamanders will be absorbed into underwater or rock crevices and survive for generations. ?
The shape of the peach blossom jellyfish is an open umbrella or an upside-down bowl, which is called an umbrella body. The edge of the umbrella has many thin-line tentacles, which are its predatory organs. The mouth faces under the umbrella and is located at the end of a tube with four lips. The food is swallowed, and the undigested residue is still excreted through the mouth, so the peach blossom jellyfish has a mouth and no anus. There is a horizontal edge film on the umbrella edge, which is the same feature of hydra jellyfish. ?
Peach blossom jellyfish is crystal clear, swimming around in the water with beautiful posture. Its umbrella body is constantly contracting and relaxing, and the water pressure in the lower umbrella cavity is pushed out of the body, thus swimming slowly in the opposite direction. When encountering food, the stinger sac on the tentacle shoots stingers, stung the captured object, instantly anesthetized it, sent it into the mouth with the tentacle and swallowed it into the stomach. Peach blossom jellyfish mostly feed on cyclops, small nematodes, small ring worms, small tadpoles and small fry. ?
Peach blossom jellyfish is a rare animal in the world, and its appearance time is generally very short, so it is difficult to find it. Because they mostly appear in the early spring when peach blossoms are in full bloom, some of them are pink and swim in the water like peach petals floating on the water, so they were called "Peach Blossom Fish" in ancient China. However, it is clearly pointed out that peach blossom fish "is not a fish, but born in water, so it is called fish;" Born when peach blossoms are in full bloom, it is named Peach Blossom Fish. This correct understanding is a great achievement hundreds of years ago. ?
In zoology, the peach blossom jellyfish was first recorded in the world in 1880. The specimen was collected from London, England, and named peach blossom jellyfish? Sorbi? Lancaster 1880). About half a century later, it was found all over the world, mainly in temperate regions such as Asia, Europe and America, and also in Oceania. The first discovery of peach blossom jellyfish in China was 1907, which was collected by a Japanese. The Japanese scholar Qiu Qian named it Yichang peach blossom jellyfish C.kawaii(Oka, 1907). ?
In the thirty-seventh year of Wanli in Ming Dynasty, there was a record of "Peach Blossom Fish" in Guizhou Zhi. This is the earliest record of peach blossom jellyfish in the world. In the Collection of Ancient and Modern Books in the third year of Yongzheng in the Qing Dynasty (1726), there is such a detailed and vivid description of the peach jellyfish: "The peach jellyfish is shaped like a elm pod and has different sizes. When they crawl in the water, they collect food. If people gather their fingers and put them aside, they don't know how to avoid others, so they take them out of the storage tank. From the surface of the water, it looks like a twisted saliva, soft and without complicated shape. " In the 19th year of Qing Daoguang (1839), it was recorded in "Peach Blossom Fish Out of Chixi River, Peach Blossoms Only Bloom, Red and White Flowers, No Flowers Behind". Other ancient books also include: "Peach Blossom Fish is round, as thin as cicada wings, and its floating surface stretches." As soon as it appeared, it said, "Take peach blossom as life and death, and when it is exhausted, there is nothing." According to the information that has been found, it is certain that China's understanding of peach blossom jellyfish is at least 270 years earlier than that of European and American countries. ?
In Zigui, it can be said that "Peach Blossom Fish" is a household name, and there is such a beautiful and moving legend circulating. Zhao Jun, the king of Han and Zhao, married the Great Wall in order to reconcile Han and Hu. Zhao Jun returned home to visit relatives before marriage, holding the lute in his arms, sitting in a boat on the Chixi River and playing a lute line with deep affection. He couldn't help but burst into tears, dripping into the river and suddenly becoming a transparent peach blossom fish. ?
Up to now, peach blossom jellyfish 1 1 species have been found in the world. Except for two species of Saussurea in Britain and Yi Shi Peach Blossom Jellyfish (1922) in Japan, the other nine species are all from China.
China peach blossom jellyfish (1939) is distributed in Leshan, Sichuan and Yichang, Hubei.
Leshan Peach Blossom Jellyfish (1939) is distributed in Leshan, Chongqing and other places in Sichuan?
Hangzhou Peach Blossom Jellyfish (1980) is only distributed in Hangzhou.
Xinyang Peach Blossom Jellyfish (1980) is only distributed in Shihe Port, Xinyang, Henan.
Sichuan Peach Blossom Jellyfish (1984) is only distributed in Qingcheng Mountain, guanxian, Sichuan.
The Zigui Peach Blossom Jellyfish (1985) is distributed in Zigui, Chongqing and other places in Hubei (with the impoundment of the Three Gorges Reservoir, the habitat of Zigui Peach Blossom Jellyfish was destroyed)?
Chuxiong Peach Blossom Jellyfish (2000) is only distributed in Chuxiong City, Yunnan Province.
Peach Blossom Jellyfish (2002) is only distributed in Zigui, Hubei.
Yichang peach blossom jellyfish (1907) is only distributed in Yichang, Hubei.
65438-0880 Saussurea involucrata is distributed in Japan, Korea, Philippines, Russia, Britain, France, Germany, Italy, Belgium, Sweden, Netherlands, Spain, Poland, Romania, Czech Republic, Denmark, Australia, USA, Canada, Panama and Chile. , has not been recorded in China. 1959 a new species of peach blossom jellyfish was reported in Taiwan Province province? Kou), while Kramp( 196 1) thinks that this species is not new, but the peach blossom jellyfish of Soxhlet, which needs to be confirmed. The Japanese historical peach jellyfish (1922) is only distributed in Japan, and only one specimen has been collected. ?
According to the investigation and study of domestic experts for more than 50 years, from 1907 to 2002 and 1995, there were 14 provinces and 53 cities and counties in China, and some areas were found only once, such as Changsha, Chengdu, guanxian, Xiamen, Xinyang, Taiwan Province and Hongkong, and a few areas appeared almost every year. The species, wide distribution and early record of peach jellyfish in China are unmatched by other countries. ?
Why do peach jellyfish suddenly appear and disappear quietly in a few days or ten days? This is to be answered from their reproductive law. Peach blossom jellyfish seen in early spring in China are mature aquatic parents, which can be divided into two types: male and female. It used to be thought that male and female peach jellyfish were indistinguishable in appearance. According to our observation, the tentacles are slender, all of them are female, the tentacles are short and thick, and the ones vertically below are male. Men and women discharge eggs and sperm into water, and after fertilization, the eggs develop into tiny ciliated floating larvae, and one end of the latter larvae contacts and fixes with foreign objects such as the center of stony soil, and develops into tiny dendritic hydra. Hydra can survive hot summer and cold winter, and germinate and reproduce in the next spring to produce water matrix. After the aquatic mother matures, sexual reproduction is carried out. 1993 The hydra found in Zigui is only 0.3 mm long, and it was found again in 2002 under the condition of artificial culture. In zoology, polyps reproduce sexually, and polyps reproduce asexually to produce polyps, which is called generational alternation. ?
100 For many years, only1/peach jellyfish has been found in the world. Although there are many species and wide distribution in China, there are only two or three places in China where peach jellyfish can be collected because of the pollution of water quality, the destruction of natural environment and ecological imbalance. Therefore, this rare species in China is on the verge of extinction. Among the nine species of peach blossom jellyfish distributed in China, Yichang peach blossom jellyfish, Xinyang peach blossom jellyfish and short hand peach blossom jellyfish have been listed in the national red list of endangered animals, which are the highest-extremely endangered species, while Hangzhou peach blossom jellyfish, Leshan peach blossom jellyfish, Sichuan peach blossom jellyfish, China peach blossom jellyfish and Chuxiong peach blossom jellyfish are listed as endangered species. ?
He Zhenwu, Ren Xu and two experts who have studied jellyfish for more than 40 years found peach jellyfish in Wuxi Cuihu Lake, and the measured PH value was 6.4. He Zhenwu said that this slightly acidic water environment is most suitable for jellyfish growth. The water source mainly comes from the nearby Luding mountain stream. ?
Peach blossom jellyfish has important academic value and ornamental value. The extinction of this precious species is not only the loss of species diversity in China, but also the permanent loss of the recorded "Peach Blossom Fish" cultural resources in ancient China. At present, the call for protecting the peach blossom jellyfish has attracted the attention of domestic academic circles and all aspects. We have begun to study specific measures to save the peach blossom jellyfish, trying to save this extremely endangered species. ?
Research experts pointed out that the peach blossom jellyfish is a veritable "living fossil" with high research value and ornamental value. As a species formed in the process of biological evolution, its status is no less than that of giant pandas. Peach blossom jellyfish recorded the development of life on earth with its unique life form. Its unique genes are of great value to the research of modern genetic engineering, and also provide conditions for studying and understanding the inheritance and evolution of species.
According to the latest report of National Geographic magazine, most jellyfish live in stagnant water areas, and their vitality is extremely tenacious. It needs little oxygen, so you will find it in the deep sea for thousands of meters. The appearance of jellyfish is not a phenomenon of environmental improvement, but a sign of environmental deterioration. With the serious water pollution, rich nutrients and disastrous plankton, a large number of fish died, and jellyfish began to flourish, but this was a prelude to another disaster. Jellyfish ate everything, plankton, fish eggs, small fish and big fish all escaped, and its prosperity made it difficult for fish to regenerate, and the consequences would be irreversible! Japan has tasted the disastrous consequences of jellyfish prosperity, please pay close attention to environmental pollution and its disastrous consequences!
There are ways to change this situation. First, pay attention to the water pollution problem and actively solve the water pollution problem in industrial production. Second, protect turtle species. Turtles are natural enemies of jellyfish, but unfortunately, humans are making turtles extinct! These are man-made disasters!
Moon Jellyfish Moon Jellyfish is a low-level coelenterate, which is composed of endoderm. There is a thick mesoderm between the two layers, which is not only transparent, but also floating. More than 95% of the body is water, according to the different classification of umbrellas: some umbrellas emit silver light and are called silver jellyfish; Some umbrellas are like a monk's hat, called a monk's hat jellyfish; Some umbrellas are like white sails on a ship, called sail jellyfish; Some are like umbrellas, called umbrella jellyfish; Some umbrellas shine with rosy clouds, called Xia jellyfish; There is a special gland in the umbrella, which can release carbon monoxide and make the umbrella expand. When encountering enemy damage or a big storm, it will automatically release gas and sink to the bottom of the sea. Under the umbrella, those slender tentacles are its digestive organs and weapons, which are covered with stinging cells and can emit venom like poisonous silk. After the prey is stung, it will soon be paralyzed and die. There is a small ball on the thin handle in the middle of the tentacles.
