Little knowledge of interesting things about sea cucumber 1. Sea cucumber knowledge

The sea cucumbers in China include all animals called "sea cucumbers" or dry sea cucumber.

In a narrow sense, it only refers to the genus Holothuria. The genus Holothuria is the largest genus of Holothurian, including 120 species.

This product belongs to echinoderms, sea cucumbers and sea cucumbers. Echinoderm is the general name of holothurian or holothurian 1, 100 invertebrates.

The body is cylindrical and soft. Dragon 2? 200 cm (about 0.75? 6.5 feet), the longest can reach more than 400 centimeters (about 13 feet), and the thickness is 1? 20 cm (0.4? 8 inches), dark color.

It has thorns and its endoskeleton degenerates into tiny bone fragments.

Many species have five rows of tube feet from mouth to * * *. The anal orifice is also responsible for breathing and excreting waste.

There are 10 or more retractable tentacles around the mouth, which are used for predation or burrowing. Many species can release their internal organs from * * * and then regenerate new ones, probably to escape the enemy.

The hidden fish of octopus is usually born in cloaca. Many of them can release toxins that are fatal to small animals, but they are not life-threatening.

Residents of the South China Sea Islands put sea cucumber juice into water to kill or paralyze fish. Sea cucumber is edible, such as sea cucumber, sea cucumber and sea cucumber.

It can be found everywhere in the ocean, mostly in shallow water, but sometimes in deep water. Mainly produced in Indian Ocean and western Pacific Ocean.

Sea cucumber 80? 100 species mostly in coral reefs. Morphological characteristics: the body is cylindrical, with a length of 10~20 cm, and the extra-large body can reach 30 cm.

Tentacle wheel, 17~30, generally 20. The tentacles are well developed.

The mouth is at the front end, mostly on the abdomen. * * * at the back end, more inclined to the back.

There are generally wart feet on the back and tube feet on the abdomen. Distribution and living environment: Sea cucumbers are distributed in many sea areas of China. There are more than 30 species in the South China Sea of China alone, most of which are Xisha Islands, and the temperate waters are mainly Shandong Peninsula and Liaodong Peninsula.

Sea cucumbers are common in tropical and subtropical oceans, and there are many kinds of coral reefs in India-West Pacific. Some are hidden, some are drilled in the sand, and some species can only be found in coral reefs.

Feeding is often rhythmic. Living in the seabed 2~40m deep; The adaptive water temperature is 0℃~28℃ and the salinity is 28 ‰ ~ 31‰; Sleep when the water temperature is higher than 20℃ in summer; The bait is mainly animal and plant debris and benthic diatoms in mud and sand; The breeding period is from June to July; It has a strong regenerative ability.

Others: Sea cucumbers crawl by stretching their muscles, and can only advance four meters per hour. When the sea cucumber can't get rid of the enemy's attack, through the sharp contraction of the body, the internal organs are quickly thrown from * * * to the enemy.

After the sea cucumber loses its internal organs, it will grow back after several weeks of growth. Sea cucumber moves very slowly, only 3 meters per hour, slower than snails, so it is good at camouflage, and its skin color is similar to the environment; At the same time, it relies on excreting internal organs to confuse natural enemies and strong regeneration ability to survive.

As long as the water temperature and water quality are suitable, even if half of the sea cucumber is cut off or eaten by natural enemies, the sea cucumber can grow back in a few months, but the premise is that the remaining half must have a head or * * *, because the growth cells are concentrated in these two parts. The natural enemy of sea cucumber is crab.

Artificial culture: At present, sea cucumbers can be cultured artificially, but feed has not been developed yet, and it still depends on natural nutrition. Shandong Rongcheng has a large breeding base.

Live sea cucumbers are not easy to preserve, because they still have certain enzymes and are easily soluble in water. Pay special attention to the fact that live sea cucumbers cannot be stained with hair and oil. Cuisine: Fried sea cucumber with scallion is the main course of Shandong cuisine, the highest-end dish.

As the raw material of dishes, sea cucumber is mainly meat, but its internal organs, especially intestines, contain high nutritional value and are generally made into ingredients of egg soup in Shandong cuisine. Preparation materials of fried sea cucumber with onion: main ingredients: sea cucumber100g, ginger and soy sauce 25g each, sugar15g, cooked lard120g, and onion 200g.

Roasted sea cucumber with onion features: a famous dish in the north, imported from Shandong, with soaked sea cucumber and green onions as the main ingredients. The sea cucumber is fresh, tender and smooth, with fragrant onion and no juice after eating. The practice of burning sea cucumber with onion: cut the sea cucumber into wide slices, control the water content after cooking, put lard into onion segments when it is half cooked, fry until golden brown, take it out and apply onion oil for later use.

Add onion, ginger, salt, cooking wine, soy sauce, sugar and sea cucumber to the broth, boil it, simmer for 2 minutes, then take it out and control drying. Add the fried onion, salt, sea cucumber, clear soup, white sugar, cooking wine, soy sauce and sugar to lard, boil and simmer for 2-3 minutes. Add monosodium glutamate and starch to thicken, collect juice thoroughly over medium heat, pour in scallion oil, and plate.

Sea cucumber, a sea cucumber. Medicinal and nutritional value of sea cucumber: Modern scientific research has proved that the nutritional value of sea cucumber is very high. Protein 15g, fat 1g, carbohydrate 0.4g, calcium 357mg, phosphorus 12mg, iron 2.4mg, and more than 50 vitamins such as B 1, B2 and nicotinic acid are harmful to human body. Among them, the content of protein is more than 55%, and there are 18 kinds of amino acids, taurine, chondroitin sulfate and sea cucumber mucopolysaccharide. Arginine is the main component of male sperm cells and the main raw material for synthesizing human collagen, which can promote the regeneration of body cells and the repair of damaged bodies, improve human immune function, prolong life and eliminate fatigue.

Sea cucumber is a typical high-protein, low-fat and low-cholesterol food with extremely low cholesterol. Because the meat is tender and easy to digest, it is very suitable for the elderly, children and the weak.

Taurine and nicotinic acid in sea cucumber have the functions of regulating nervous system, quickly eliminating fatigue and preventing skin aging. In addition, taurine, lysine and methionine contained in sea cucumber are almost absent in plant foods. Pharmacological experiments show that chondroitin sulfate and Stichopus japonicus mucopolysaccharide contained in sea cucumber have special effects on human growth and development, anti-inflammatory osteogenesis, prevention of tissue aging, promotion of wound healing and inhibition of various cancer cells. = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = For more details, such as cooking methods, please refer to /view/52026544.

3. Detailed knowledge of sea cucumber

The nutritional value of sea cucumber has been widely recognized, but how to soak sea cucumber correctly so that its nutrition will not be destroyed is a big problem for ordinary families after buying dry sea cucumber. The following briefly introduces two soaking methods of sea cucumber. Let's compare and see if our sea cucumber soaking method is correct.

Hot bubble method

First, soak the sea cucumber in hot water for 24 hours (it can be boiled in cold water directly, and then covered with stew for 4-5 hours), then take out the internal organs from the lower abdomen (it is popular to eat sea cucumber internal organs at present), add new water, cook for about 50 minutes with strong fire, soak in the original soup, and eat after 24 hours.

Usually, it is faster to soak your hair in hot water. It is most suitable for the elderly, the sick and the weak.

Cold bubble method

1, bubble Soak the sea cucumber in clear water for about 3 days, and use mineral water or tap water (you can change the water halfway and leave the water for soup).

2. Soak soft and gut, wash the black things inside, and then pick out the sea cucumber tendons inside (the most convenient thing is to use a toothpick), remember not to throw them away.

Step 3 cook. Put it in a clean oil-free pot and add tap water to cook. Sea cucumber sausage can also be put in and cooked together. After the water boils, cook for 40 minutes on low heat. Try with chopsticks, and then cease fire.

4, bubble. Put it in a clean basin and soak it in mineral water for 24 hours, changing the water twice during the period, and then you can eat it (with mineral water or tap water). This method needs to change the water several times in hot weather, and always pay attention to whether it softens.

Now more and more people choose to buy instant sea cucumbers, because instant sea cucumbers can be eaten without foaming, which is convenient and quick, and the nutrition is not destroyed.

Special reminder: To soak in dry sea cucumber, you should first roast dry sea cucumber on the fire a little, and then soak it in warm water for one night, which will help the dry lime on the epidermis to fall off.

The next day, gently brush the epidermis with a soft brush, boil it in clear water for half an hour, and then turn off the fire and soak it.

Sea cucumbers are perishable when exposed to oil, so the utensils for soaking sea cucumbers must be clean and not contaminated with oil, alkali and salt. In particular, it is necessary to avoid contact between oil and water and sea cucumbers that are not completely foamed, otherwise the outer skin will be soft and rotten, but the inner layer will still be hard.

The prepared sea cucumber can't be frozen, otherwise it will affect the quality of sea cucumber, and it is not advisable to send too much at a time.

4. Knowledge about dry sea cucumber

Sea cucumber sea cucumber name: Stichopus japonicus variety Lailiu: Yellow Sea.

Properties: This product belongs to Echinoderm, Holothurian and Holothurian. Living in the seabed 2~40m deep; The adaptive water temperature is 0℃~28℃ and the salinity is 28 ‰ ~ 31‰; Sleep when the water temperature is higher than 20℃ in summer; The bait is mainly animal and plant debris and benthic diatoms in mud and sand; The breeding period is from June to July; Has a strong regeneration ability; It is widely used and has high nutritional and economic value.

Qin Xiao, a sea cucumber, guards the sea cucumber to crawl by stretching muscles, and can only advance four meters per hour-Underwater World Sea cucumber is an echinoderm living on the bottom of shallow sea, most of which are edible and rich in nutrition, and is known as "ginseng in the sea". The cylindrical body of sea cucumber is covered with thorns and looks like cucumber.

This limp body has no powerful self-defense weapon and no ability to swim quickly. It can only rely on the contraction of the abdominal tube foot and muscles, and it is difficult to resist the enemy's attack. Although it looks strange, it occasionally scares each other and likes to hide in the cracks of rocks, but because it is weak and incompetent, it will inevitably be attacked by other marine animals.

However, sea cucumbers have their own protection methods. Sea cucumber will play "separation" when it can't get rid of the enemy's attack.

Through the intense contraction of the body, the internal organs are quickly thrown at the enemy from * * *, and the damage is therefore helpless to leave. After the sea cucumber loses its internal organs, it will grow its internal organs again after several weeks of rest.

With this superb skill, sea cucumber can escape from the enemy and protect itself.

5. Who can tell us about the species and related knowledge of sea cucumber?

The magical sea bottom waves of sea cucumber are smooth, and algae flourish under rock reefs and on the fine honey sand bottom covered with leafy algae. There is an echinoderm, that is, sea cucumber.

Sea cucumber is one of echinoderms with the greatest economic value, and there are about 900 species in the world, ranging from shallow sea to more than 8000 meters deep sea. There are about 100 species in China's sea area, ranging from Bohai Bay and Liaodong Peninsula in the north to Nansha Islands in the south, especially Xisha Islands, with more than 20 species.

There are some world-famous species in China, such as sea cucumber with black body and black chest; White ginseng, a kind of snake with rough meat, is often a submerged fish in cloaca; Radiant anal ginseng, short and blunt body, smooth back; Japanese ginseng (southern waters) is a large, thick and tender sea cucumber with a length of 1 m and a width of1cm. Most sea cucumbers are green or slightly green and look like cucumbers. Their English translation is called sea cucumber.

But some are worms, some are like buckets, and some are like carrots. Sea cucumbers like dark living environment and often hide under coral reefs.

They usually inhabit the sediments in the intertidal zone and the lower part of the subtidal zone, and move slowly by the expansion and contraction of the tube feet and muscles, feeding on organic debris, copepods, radiolarians and other microorganisms in the sediments. Sea cucumber is muscular and can stretch and curl freely.

Sea cucumber moves slowly, and it is difficult to escape the attack of carnivores who can dehydrate and swim. Sea cucumbers make their homes on the sand at the bottom of the sea, and you can find their hiding places along the tracks of sea cucumbers.

When it was removed, it was not easy to find a rock. When you try to catch it, its body suddenly contracts, which is the basic action of its defense. This action is quite effective against natural enemies.

The body color of sea cucumber is in harmony with the color of the surrounding sediments. This can play a certain role in dealing with natural enemies, and can also guard against sudden attacks by human beings.

However, sea cucumber does not rely entirely on the protective color of its own body, but also relies on strength to forcibly push away the sediment to cover its own body as a cover. Sediments are also food for sea cucumbers.

Of course, here refers to the fine nutritious sand containing organic matter and bacteria. The sea cucumber swallows these fine sands, passes through the long digestive tract, absorbs nutrients and discharges sediment.

Although sea cucumber belongs to the same family as starfish, it is slightly more delicate than starfish. It can't stand the high temperature above 20℃, but it also has a clever way to deal with it-sleeping in summer.

In the relatively long days from summer heat to cold dew every year, when the water temperature exceeds 20℃, the sea cucumber quietly moves deeper into the sea, and many individuals gather together like partners in trouble, lurking under the seabed rocks, with their backs up, shrinking, unable to eat or move, and entering the summer sleep state. This can reduce metabolic rate, conserve body energy and tide over difficulties.

When the water temperature drops below 20℃, they wake up from a deep sleep and regain their usual vitality. The sea, like a starfish, has a strong regenerative ability. Even if its body is cut into two or three sections and put back into the sea, each section will produce a complete sea cucumber.

Sea cucumber has another trick that starfish don't have. When it is injured by the enemy or polluted by strong seawater, it will forcibly expel the silt-filled viscera from its mouth or mouth. Throw it at and confuse the enemy, and take the opportunity to escape.

If you don't need to use it twice in the future, you will slowly grow new internal organs. This phenomenon is called sewage discharge.

Sea cucumber was named by ancient China people. "Its sexual warming; Enough enemy participation ",hence the name.

Sea cucumber is an echinoderm, also known as sea cucumber, which grows on rocks or seaweed at the bottom of the ocean. There are more than 800 kinds of sea cucumbers, and only more than 20 kinds are edible.

The varieties of sea cucumbers vary from place to place. China's Xisha Islands and Hainan Island are rich in Plum Blossom Ginseng and Wuyuan Ginseng. Fujian and Zhejiang produce soap ginseng and light ginseng; The northern sea cucumber is only Stichopus japonicus, which is a relatively precious edible sea cucumber variety. Observing the shape of sea cucumber from the aquarium, its shape is quite ugly. Its slender and round body is covered with meat and fat, and its surface is covered with things like meat spines. No wonder people call it "sea cucumber" vividly.

On the other hand, sea cucumber is ugly, but its survival history is surprising. It appeared earlier than primitive fish and began to exist in Precambrian more than 600 million years ago. After systematic study by paleontologists, the bone fragment fossils of sea cucumber have become an important basis for stratigraphic paleontologists to divide strata and study paleogeology, and even become the standard fossils of Jurassic.

More than ten years ago, paleontologists in China discovered the skeleton fragments of sea cucumber in the Permian strata in Huaying Mountain, Sichuan and Changxing, Zhejiang (more than 200 million years ago). Sea cucumbers live in the depths of the sea and can't swim. They just crawl on the seabed by stretching their legs and muscles.

The crawling speed is quite slow, 1 hour can't walk 3 meters. It was born with no eyes and no sharp weapon to scare the enemy.

In this way, for hundreds of millions of years, in the ocean world where the law of the jungle prevails, how did they survive so far? Unusual dormancy It is known that some animals on land have the habit of hibernating. In the cold winter, the water-cooled grass withered and it was difficult to feed, so we had to hide in the nest and rely on the nutrients in the body to survive.

Sea cucumbers, on the other hand, choose to sleep in summer when food is abundant. Take Stichopus japonicus as an example. When the water temperature reaches 20℃, it quietly moves to the dark place of deep-sea rocks, hides at the bottom of the rocks, and faces down with its back.

Sleep for three or four months. During this period, you can't eat or move, and your whole body shrinks and hardens until after autumn, when you wake up and resume your activities. Strange, why do sea cucumbers hibernate in summer? Oceanographers explained that on weekdays, sea cucumbers feed on small creatures, which are sensitive to the temperature of seawater. When the sea surface is heated, they will go upstream, and when the sea surface is cold, they will dive back to the bottom of the sea.

After summer, when the sea surface gets warmer, the small creatures living in the sea will go to the upper waters to breed once a year, but the sea cucumbers living at the bottom of the sea can't follow them and are forced to stop eating. Have to hide under the stone to rest and maintain.

Facing the dangerous underwater environment and vicious and cunning enemies, sea cucumbers protect themselves in a special way. Wind and waves will involve poorly attached sea cucumbers in dangerous situations.

But sea cucumbers can predict the weather. When the storm came, it hid in a crack in the stone. When fishermen found that there were no sea cucumbers on the seabed, they knew that a storm was coming and quickly closed their nets and returned. When the sinister sailboat and the greedy and ferocious shark approached quietly, the alert sea cucumber quickly dived into the sticky and long intestines and branches in the body cavity with water and lungs.

6. Sea cucumber has the ability of "sleeping in summer". What other interesting animal knowledge is there?

There is a summer sleeping dog in Africa, which is very afraid of heat. In dog days, it can always find a cool summer resort and sleep for more than 20 days.

On the island of Madagascar in Africa, there is a porcupine that feeds on earthworms. Because of the hot summer, earthworms can't survive in the shallow layer, and porcupines have no food, so they have to go into a long summer sleep.

There is a strange lungfish that lives in rivers in Africa, America and Australia. This fish is about 1-2 meters long and has gills and lungs. When the hot sun evaporates the river, causing a drought period of several months, the lungfish will dive into the mud and sleep until the rainy season comes.

There are no tree fish in South Africa. In the hot summer, it went ashore, climbed to the shady side of the branches, and slept for more than a month.

Snail in the desert of Africa, when summer comes, it gets into its shell and sleeps soundly. It looks like an empty shell hidden in the sand. As soon as the weather turned cold, it began to rain in the desert, and it sucked up enough water and climbed out again.

Misgurnus anguillicaudatus lives in the waters along the Danube. In summer, the river dries up, enters the mud without eating or drinking, and enters a state of summer sleep. It only relies on its special intestine to breathe air and maintain life.

Hare There is a big hare in western South Africa, which is rich in fat and afraid of heat and summer. So for more than two months in midsummer, it hardly eats anything and sleeps in the hole all day.

7. What are the special functions of sea cucumber?

The special function of sea cucumber is regeneration.

Cut a sea cucumber into three parts and throw it into the sea. Each of these three parts will grow into a complete sea cucumber.

Its process needs 3? Seven months. When sea cucumber lays eggs, it is surrounded by rosy "clouds" and breeds a new generation of life.

Sea cucumber larvae take sweet potatoes as their home until they grow into adults. Each cluster of seaweed is a unique nursery for sea cucumbers.

Small sea cucumbers are safe there, and fierce starfish or crabs can't get close. After delivery, the sea cucumber was weak, so she sneaked into the cave to recuperate until June 5438+00.

They also do this to avoid fierce starfish, because at this time they are unable to cope with starfish attacks.
