What is the largest shellfish in the world?

Shells are small, but hard and delicate. All kinds of shellfish, large and small, are very beautiful on the sunny beach. But many people don't know what the largest shellfish in the world is. Let's take a look at the amazing world's largest shellfish.

The largest shellfish in the world? Wangbei

(chēq？ ) It's also the famous car canal. Was it written by the people? Hey? The largest bivalve shellfish in the ocean is called "the king of shellfish".

Mainly distributed in Indian Ocean and Pacific Ocean. There are 6 species in China, distributed in Taiwan Province Province and the islands and reefs in the South China Sea. It is the largest kind of bivalve, with a maximum shell length of 1.8m and a weight of 500kg. The closing force of the two shells is amazing, and it is said that the chain of the anchor can be easily broken. Shells can be used as a bath basin for babies. Hard shells can be used to make all kinds of utensils, and meat can be eaten. Manjianghong lives in shallow water between tropical marine coral reefs and is fixed on coral reefs with hard feet. It relies on seawater to bring plankton into the body and digest and absorb it as food. Trionyx viennensis has a * * relationship with a kind of zooxanthellae, and the edge of its mantle has a special structure called vitreous body, which can gather light and make zooxanthellae multiply in large numbers, and zooxanthellae can provide some nutrition for Trionyx viennensis.

morphological character

Shells are large or extra-large, with thick shells and rough surfaces. The two shells are equal, and there are strong protruding radial ribs on the shell surface, and there are often scales or thorns on the ribs. Some kinds of ribs have thick scales. External ligament, usually with a large foot wire hole. The hinge has a main tooth and 1-2 rear teeth. Coat marks are intact, the former obturator internus disappears, and the latter obturator internus is near the center. Azolla is the largest bivalve, and its shell length can reach 1 m. The shell is slightly triangular, the top is curved and the edge is wavy. The surface is gray, and there are several deep grooves on it, which looks like it has been run over by wheels. The mantle is very large and rough, with five thick belt-shaped radial ribs, obvious growth rings and bending and overlapping folds on the shell surface. The inner surface of the shell is white but full of luster. There are intercostal grooves corresponding to radial ribs, and the hinge part is long and narrow. Both shells have a main tooth and a rear tooth. The main teeth are short and the rear teeth are weak.

The appearance of the tortoise shell is not beautiful, but when it is opened in the sea, its body is colorful, and its cloak is extremely rich in color, not only in bright colors such as peacock blue, pink, emerald green and brown red, but also in various patterns.

Living habits

Trionyx sinensis is often associated with a large number of zooxanthellae. This unicellular algae can circulate in water chestnut and carry out photosynthesis, which provides abundant nutrition for water chestnut. There is a structure called vitreous at the edge of the mantle of cockroaches, which can gather light and make zooxanthellae multiply in large numbers. This special relationship between clams and algae is called reciprocal growth. In addition, they eat plankton. Meat is edible, and big shells can be used as water containers or raw materials for shell carving. Some dragonflies can produce pearls. Small shells can be fired with lime and can also be used for viewing. In some countries, pangolins and pangolins have been successfully farmed. When the sea water flooded the sea, it opened its shell and stretched out the thick mantle edge for activities. Like other bivalves, dragonflies carry food through the sea water flowing through their bodies. But they not only eat in this way, but also have the ability to grow food in their own tissues. Insect yellow algae can make full use of the convenient conditions provided by the mantle to reproduce, such as space, light and phosphorus, nitrogen and carbon dioxide in metabolites; You can use zooxanthellae as food. The reason why it grows so huge is that it can get food from two aspects.

distribution range

Indian Ocean and Pacific Ocean. Especially near the low tide areas in Indonesia, Myanmar, Malaysia, the Philippines, Australia and other countries, there are many coral reefs or shallow reefs. China, Hainan Province and South China Sea Islands are also distributed. The shell is slightly triangular, the top is curved and the edge is corrugated. On the gray surface, there are several deep ditches, which look like they have been run over by wheels. The cloak is big and bright. Trionyx sinensis is often born with a large number of zooxanthellae. This kind of unicellular algae can circulate in water chestnut and carry out photosynthesis, providing abundant nutrition for water chestnut. There is a structure called vitreous at the edge of the mantle of cockroaches, which can gather light and make zooxanthellae multiply in large numbers. This special relationship with algae is called reciprocal growth. In addition, they eat plankton. Edible shells with meat can be used as reservoirs or raw materials for shell carving. Some dragonflies can produce pearls. Small shells can be fired with lime and can also be used for viewing. At present, some countries have successfully cultivated scaly and scaleless water chestnuts.

Is the time and space I can stay in this world longer and more than life in a shell? Should I also use my ability to do what I can more exquisitely, meticulously and meticulously?

Various practices of shellfish and seafood

Steamed vermicelli

Shellfish as big as shells will do.

Shellfish used in steamed garlic vermicelli are mainly shellfish with large shells, such as scallop, razor clam, lion tongue, swan egg, oyster and Hawaiian shellfish. Yang, the person in charge of Qingdao Fish Kitchen Niu Hotel, introduced that steamed shellfish with garlic powder is a Cantonese-style seafood steamed dish, and the main ingredients are garlic, vermicelli and various shellfish. The main cooking process is steaming, but before steaming, garlic needs to be fried with oil, and then the juice made of soy sauce and sugar is poured on the shellfish. What you want is the delicacy of shellfish and seafood and the smell of garlic.

Taking scallop as an example, Yang introduced several points of steaming garlic vermicelli. Wash scallops on both sides with a brush, remove one side of the shell with a knife and put it on a large plate. Longkou mung bean vermicelli soaked and drained. Saute garlic, add salt, and fry raw garlic into juice. Boil water in a pot. After the water boils, put the vegetables into the pot, add the vermicelli and pour in the garlic juice. Cover and steam for 3 minutes.

Steamed in soy sauce

Add a fresh taste.

Shellfish steamed with garlic vermicelli can be steamed with soy sauce. Andy, head of Qingdao Xiujiangnan Hotel, introduced that soy sauce is a unique seasoning for cooking. Soy sauce is salty, salty and fragrant, which can increase and improve the taste and color of dishes.

Andy introduced the main points of steamed soy sauce represented by Hawaiian shellfish. First, wash the Hawaiian shells, cut them one by one from the middle with a knife, change one into two, and put them in a plate. Then wash the lobster sauce, add salt, monosodium glutamate, starch, peanut oil and sugar, mix well and sprinkle on the Hawaiian shellfish. Boil the water in the steamer, put it on a plate, pour soy sauce on it, and steam it for 6 minutes. This kind of lobster sauce is delicious.

Roast with garlic

Remove fishy smell and increase fragrance.

Baked shellfish with garlic is similar to steamed shellfish with garlic, but the raw materials used are quite different. Baked shellfish with garlic is suitable for shellfish with thick shells, such as oysters, scallops, swan eggs and Hawaiian shellfish. Baked shellfish with garlic, generally without vermicelli, highlights the burnt flavor of garlic and the umami flavor of shellfish seafood. Zhang Lei, executive chef of Qingdao Zhonghang Hotel, said that jellyfish is the most delicious from winter to Qingming the following year.

Zhang Lei said that the method of burning oysters with charcoal is very simple. Just put garlic, Jiang Mo and other condiments into the oyster that has just been pried open, and then bake it directly on the fire, which not only ensures the delicate flavor of the oyster, but also removes the fishy smell of the oyster with garlic. If it is not good to barbecue at home, you can barbecue in the microwave oven or fry in a non-stick pan. The oven is hot, pour the oil and bake the oysters on the stove. When oyster sauce seeps out gradually, sprinkle with onion, garlic and other seasonings and marinate for two or three minutes.

Fry in yellow oil.

The combination of Chinese and western tastes full.

According to Andy, frying is to marinate the raw materials, then paste them and fry them. However, shellfish and seafood are fresh and tender, and can also be directly fried in yellow, without hanging paste, combining Chinese and western. This dish is suitable for scallops, Hawaiian shells, swan eggs and other shellfish with relatively large and tight meat. Like oysters, the meat is tender and not suitable.

Andy introduced that the belt should be washed with kitchen paper and dried for later use. Heat the frying pan with high fire. When the pan is hot, add butter and reduce the heat. Add the belt and start frying. You can sprinkle Shanghai salt when frying. One side is golden, change the other side. Until both sides are golden, sprinkle with shredded pepper. You can also use apple vinegar and olive oil as vinegar juice, add a little sugar, and dip it in without pepper.

boiling water

Suitable for fresh and sweet shellfish.

Andy told reporters that baking is a cooking method. Food is boiled in boiling water and then taken out immediately to prevent the loss of nutrients in food due to high-temperature cooking or the food itself from getting old and turning yellow. Generally, soup is used as the heat transfer medium, and vegetables are cooked by water boiling, which is a special method to make soup dishes, and the cooking speed is faster. There are fresh and sweet shellfish suitable for retting, such as clam, stone lion tongue and scallop. It tastes like oysters and is not suitable for retting technology.

This dish is not difficult to cook. The key is to make the soup well. What is needed is clear soup. There really isn't, so I use clam soup and a stone tongue instead. Remove the skirt from the stone tongue meat, cut it into thin slices and wash it. Cut coriander stalks and leek greens into fine powder, plate them separately and serve with pepper vinegar. Boil the broth in a pot, add proper amount of salt and chicken oil, put it in front of the guests, pour in the meat with stone tongue and eat it while it is hot. As soon as the soup is cold, the stone's tongue will get old. Be sure to eat it while it is hot. You can also use a hot pot. People who eat each hold an empty bowl, put the sliced meat with stone tongue into the soup with chopsticks, and rinse it up and down seven or eight times, that is, rinse it and eat it immediately.

Nutritional value of common shellfish

Oyster is one of the larger oyster species, which generally grows at the intersection of rivers and the sea, on the shallow sea in the inner bay, half salty and half light. Due to the limitation of growth conditions, it is less than other varieties in quantity, so its economic status is also relatively high.

Oysters are nutritious, high in protein and low in fat. It contains eight essential amino acids, as well as glycogen, taurine, glutathione, vitamins and minerals. What are the main ingredients of oysters? Glycogen?

Oysters are the best food for calcium supplementation and are rich in phosphorus. Because calcium needs the help of phosphorus when it is absorbed by human body, it is beneficial to the absorption of calcium.

Oysters are large and full, with light yellow color, bright color and uniform size, which is the most suitable top grade in winter and spring. So there is a saying in the west:? Don't eat oysters in the month without the letter R. ? What's it called here? A month without the letter r? In English it means five months, six months, seven months and eight months. After September, a large amount of glycogen was stored in oysters. From 10 to March of the following year, betaine in oysters is also increasing, so the taste is more delicious.
