Crab
Crab: páng xiè
Explanation: 1. The common name of crab.
2. Also known as "crab clam".
Crabs are crustaceans, and their bodies are protected by hard shells. In terms of biological taxonomy, crabs, shrimps, lobsters, and hermit crabs are the same kind of animals. Most types of crabs live in or near the sea, although some live in fresh water or on land.
Crabs breathe through gills.

Life habits and reproduction of crabs
[Edit this paragraph]
They rely on female crabs to give birth to baby crabs, and each time the female crab will lay a lot of eggs, The quantity can reach millions or more. After these eggs hatch in the abdomen of the mother crab, the larvae can break away from the mother and float around with the coastal currents. After several shellings, they grow into big-eyed larvae. The big-eyed larvaes grow into young crabs after several shellings. The appearance of the young crabs is almost the same as that of adult crabs. After several more shellings, they turn into crabs. Most saltwater crabs discharge their eggs directly into the ocean without hatching after their eggs mature.
The hard carapace on the crab can protect the crab from natural enemies, but the carapace does not expand as the body grows. Therefore, the growth of crabs is episodic, that is, after a period of time, the body will continue to grow after the old shell is shed. The largest crabs on earth are spider crabs, with their legs spread up to 3.7 meters wide. The smallest crabs are bean crabs, less than half a centimeter in diameter.
Although crabs are small, they have all five internal organs. After removing the hard shell of the crab, we can find that the crab's body is protected by a shell. These shield-like shells are called carapace by biologists. The body of the crab is symmetrical and can be divided into the forehead area, eye area, heart area, liver area, stomach area, intestine area and gill area. There are appendages on both sides of the crab's body. The appendages on the head are called antennae, which provide touch and smell functions. Some appendages have mouth functions, which are used to tear food apart and bring it into the mouth.
The crab's chest has five pairs of appendages called thorax. The pair of appendages in the front are equipped with strong claws, which can be used for foraging. The remaining four pairs of appendages are the crab's feet. Crabs rely on these four pairs of appendages to move and move. Their walking appearance is unique. And interestingly, most of them are walking sideways instead of going straight forward. The exception is monk crabs, which walk straight.
Crabs spend most of their time looking for food. They are not picky eaters and will eat anything their pincers can get. Small fish and shrimp are their favorite, but some crabs eat seaweed and even animal carcasses or plants.
Crabs eat other animals, and other animals may also eat crabs. For example, humans regard crabs as delicacies. There are also waterfowl that eat crabs! Some fish also like to eat crab legs just like humans. When young and immature crabs float in groups in the sea, they may be gobbled up by other marine life. Therefore, crabs must lay many eggs when they spawn.
Fiddler crabs are common crabs on the beach. Why are they called fiddler crabs? Because these crabs wave their large claws as if they are waving at the tide, this is how the name "tide fiddler" comes from. In addition, the giant claws of the male fiddler crab look like playing a violin, so they are also called fiddler crabs or fiddler crabs.
The reason why crabs walk sideways
[Edit this paragraph]
a. Geomagnetic field theory
Crabs rely on the geomagnetic field to judge directional. Over the long time since the formation of the Earth, the magnetic north and south poles have reversed many times. The reversal of the geomagnetic poles disorients many organisms and even causes extinction. The crab is an ancient migratory animal. Its inner ear has small directional magnets and is very sensitive to geomagnetism. Due to the reversal of the geomagnetic field, the small magnets in the crab's body lose their original orientation. In order to survive the reversal of the geomagnetic field, crabs adopt the approach of "keeping the same in response to all changes". They simply do not move forward or backward, but walk sideways.
b. Biological perspective
The head and thorax of a crab are indistinguishable in appearance, so they are called cephalothorax. The full legs of this animal grow on either side of its body. The first pair of chelicerae is not only a tool for digging holes, but also a weapon for defense and offense. The remaining four pairs are used for walking and are called walking legs. Each foot is made up of seven joints, and the joints can only move up and down. The width of the thorax of most crabs is greater than the length, so when crawling, they can only bend one side of the foot and grasp the ground with the toes, while the other side of the foot stretches outward and begins to contract when the toes reach the ground far away. The originally bent foot immediately straightened, pushing the body to the opposite side. Since the lengths of these pairs of legs are different, the crab actually moves sideways and forward.
However, not all crabs are allowed to run amok. For example, long-armed monk crabs that live in groups on the beach can run forward. Many spider crabs that live in seaweed can also climb vertically on the seaweed. The answer to why crabs run rampant seems to provide us with a clue to solving certain problems in life. When a person lives in the world, he will encounter many changes that are independent of human will, and the best way to adapt to these changes is to adjust himself. Otherwise, it will only lead to the tragedy of "extinction" like those creatures that are not adapted to the reversal of the geomagnetic pole. In fact, when dealing with the troubles in life, if you don't move forward or backward, but go sideways, you may have a different world. Others may ridicule crabs for their ugly walking posture, but no one can deny that crabs walk faster when they walk sideways.
c. Experimental discovery
Through experiments, it was discovered that the bony eyes (where muscle bundles pass through) in the crab body are connected to the limbs. There are two upper and lower bony eyes for each limb ( That is, two bundles of muscles) are connected to it. And the bending direction of the joints at the base of its limbs is in the dorsal and ventral direction, so when the muscles contract, it affects the limbs to move in the dorsal and ventral direction, so the crab moves laterally.
Crab Purchasing instructions
[Edit this paragraph]
You cannot eat dead river crabs, but sea crabs are okay.
Crabs are unsightly in appearance and run wildly when walking, but they taste extremely delicious. Especially the hairy crabs produced in Yangcheng Lake in Jiangsu Province are famous all over the world for their fat and yellow bodies in late autumn.
Fresh crabs are very delicious. However, if the caught crabs die, their flavor will be gone, and people may suffer from poisoning symptoms after eating them. So, what is the reason?
Crabs live in water and like to eat dead fish, dead shrimps and other decaying animal carcasses in the water. Crabs will be infected with certain bacteria in their bodies. River crabs, in particular, mostly grow in dirty river ponds, and there are a lot of germs inside and outside the crabs. Live crabs can excrete bacteria through the body's metabolism; once a crab dies, the bacteria in its body will multiply and decompose the crab meat. Some bacteria will also produce toxins. If people eat such crabs, it will cause food poisoning, which is common. Symptoms include nausea, vomiting, abdominal pain, and diarrhea; in severe cases, dehydration, electrolyte imbalance, convulsions, and even shock, coma, and sepsis may occur.
If the above situation occurs, the patient should be sent to the hospital immediately and given intravenous infusion of glucose saline or compound sodium chloride, supplement fluids, and encourage the patient to drink more water, tea, etc. Promptly replenish potassium to maintain electrolyte balance, and administer sensitive antibiotics to control and prevent infection. People with low blood pressure are given vasopressor drugs and other symptomatic treatments.
Therefore, when purchasing crabs, be sure to pay attention to whether they are fresh. Do not buy dead crabs, especially river crabs, and cook them thoroughly before use to kill the contaminating bacteria inside and outside the crabs. .
The history and taste of crabs
[Edit this paragraph]
Crabs are served with Baiweitan
Miao Shiyi
"The autumn wind blows and crabs' legs itch", "Crabs are served with a light taste".
Crab is a very individual animal with many legs and many names. Su Dongpo called it "Jian Tuan". His poem said: "It makes me laugh at the greedy prefect of Wuzhong. One poem exchanges for two Jian Tuan." "He once called it "Neihuanghou", and the poem goes: "I have always admired Neihuanghou, the flavor is the best before the bottle." Tang Yanqian gave the crab the name "蝤蛑": "It is full of praise and rich in flavor, and it is sharp. Tuan Jie is better than Tuan Navel." Lin Bu was ingenious and called the crab "Guosuo": "The grass and mud are like Guosuo, and the clouds and trees are called hooks (cars and boats)." The characteristics of crabs are very obvious. In the Tang Dynasty, Pi Rixiu. "It was already known before I traveled to the sea. It has bones and is still alive from the flesh. There is no fear of thunder and lightning, and the sea dragon king is also rampant." The whole poem does not mention a single word crab, but it vividly outlines the shape of crab.
Eating crabs has a long history in our country. According to "Jizhong Zhoushu", during the reign of King Zhou Cheng, Haiyang offered crabs as tribute, indicating that the king had listed crabs as royal food at that time. There is a record of "Crab Xu" in "Zhou Li", which is said to be a kind of crab sauce. Jia Sixie of the Northern Wei Dynasty's "Essential Techniques for Elevating the People", in addition to steaming, deep-frying, noodles, and drunkenness, there is also a detailed introduction to pickled crabs. Fu Gong of the Song Dynasty compiled various crab-eating methods in his book "The Crab Classic". Gao Sisun, a native of the Song Dynasty, wrote the book "Crab Lue" based on the "Crab Classic", giving a detailed introduction to crab products and crab delicacies. There are records of eating raw crabs in "Zhongjilu" of the Song Dynasty. "Yun Guitang Food System Collection" written by Ni Zan of the Yuan Dynasty contains the cooking method of crab. In the Ming Dynasty, "Agate Crab" appeared, and in the Qing Dynasty, crab dishes such as "Crab Roe Douzi" and "Crab Lamb" appeared.
There are many famous crab eaters in the history of our country. For example, Zhang Dai, a writer in the Ming Dynasty, was a famous crab-eater. He and his literary friends would hold a crab party from January to October every year, and they would gather together in the afternoon to cook and eat six crabs for each person. In "Memories", a special article "Crab Club" was written. Li Yu, the opera theorist of the Qing Dynasty, was fond of eating crabs and was known as the "Crab Fairy". Every year, when the crabs were not out, Li Yu would save his money and wait for the crabs to come on the market. When his family members saw him, they all laughed at him for "taking crabs as his life." Li Yu also claimed that the money he spent to buy crabs was "life money," and said to himself: "Crabs will never be forgotten for a day in their lives. They are addictive and willing to give up." It cannot be forgotten, and it cannot be described in words." Li Ruiqing, a famous painter in the late Qing Dynasty and the early Republic of China, had no money to buy crabs, so he painted a hundred crab pictures to satisfy his craving. He was known as "Li Bai Crab".
There are also descriptions of crab feasts in the literary works "Jin Ping Mei", "History of the Ming Palace" and "Dream of Red Mansions". Especially in the thirty-eighth chapter of "Dream of Red Mansions", the Qing Dynasty writer Cao Xueqin described the crab feast in the Grand View Garden and people The shape of the crab is vividly depicted.
There are many varieties of crabs. Qing Li E's "Lake crabs come out of Fengtian every year, Wu Lu eight kneels to enter especially fresh", which writes about lake crabs; Song Meiyao's "Harvest rice and sell river crabs every year, where does February come from", depicts It is a river crab; Tangpi Rixiu's poem "The blue and green basket is dyed with moss clothes, when Wu Yi first sent it to the people from the north. When I was away from home, I had a feeling of stone sailing, but when I lost my companion, I only knew about the sea and the moon", which sang about the sea crab. There are many famous crabs in various parts of my country, such as Tianjin purple crab, Liaoning Xingcheng swimming crab, Suzhou Yangcheng River hairy crab, Wenzhou Pingyang Yanting river crab, Shandong Laizhou crab, Guangdong Wuchuan Zhiliao crab, Chaoshan red crab, etc. .
Crabs, with orange-red egg masses, white jade-like fat, and soft jade-like crab meat, can be said to be "a bucket full of red jade, and the double claws burst out with the fragrance of honey." No wonder Lu Chun, a Tang Dynasty man Said: "Han Huang Bo (i.e. crab) is the most delicious flavor in the world." Because crab is so delicious, literati did not hesitate to praise the flavor of crab. For example, in an ancient poem: "The taste is especially worthy of recommending wine. The most fragrant and beautiful is orange. The shell is thin and rouge-dyed, and the cream is plump and amber. "It is said that the image of crab meat is beautiful. Huangshan Valley's "belly of gold and jade, two pincers bright moon and autumn river", it is said that the taste of crab can help people enjoy themselves. In the Tang Dynasty, Li Bai held up his pincers and raised his goblet. He was so pleased with himself that he couldn't help but blurt out: "The crab pincers are gold liquid, and the low hills are Penglai. You must drink fine wine and get drunk on the high platform by the moon." Su Dongpo in the Song Dynasty said bluntly: "If you don't know that Mount Lu is letting you down, you won't be able to live up to your expectations." Eating crabs will disappoint you. "Comparing crabs with Lushan Mountain shows the poet's deep love for crabs. Zhang Lei of the Song Dynasty wrote "I know from afar that Lianshui crabs are already frosty in September. They are huge and heavy in gold, and the crabs are fat and fragrant with white jade." It is enough to make people salivate. Lu You Kuai Ren said quickly: "The fat crab has been cracked for a while, and the wine is green, and the old eyes are bright." The poet said that when he just started to crack the fat crab, his saliva flowed down, and he held the wine with his pincers, and his dim old eyes also lit up.
“The ripe yellow japonica rice falls in the west wind, and the fat enters the south of the Yangtze River in ten months. The teeth are white when kneeling horizontally and staggering, and the round navel sucks the cream red from the flanks” (Song Dynasty·Song Dynasty); “The calf is healthy lying in the grass at sunset, Chrysanthemums leave autumn colors and crab claws are fat" (Fang Yue, Song Dynasty). The golden breeze is refreshing, holding a crab and admiring the chrysanthemums, why not?
The theory of eating crabs is "literary and martial"
[Edit this paragraph]

It's the time to eat crabs again. People today eat crabs differently from those in ancient times. How did the ancients eat crabs?
Our country has a long history of eating crabs, and crab dishes are also constantly developing. There are famous crab dishes in various periods. The ancients praised the deliciousness of river crabs, and many people wrote poems to praise them. "Crabs" written by Tang Xuanqian of the Tang Dynasty said: "It is full of cooked heaps of delicious food, and the orange paste sauce is delicious. A bucket full of red jade is broken, and the double claws burst out with the fragrance of honey." "Li Yu of the Qing Dynasty said: "Crab is fresh and fat, sweet and greasy, white like jade, and yellow like gold. It has reached the ultimate in color, fragrance and taste, and nothing can be better."
"Zhou Li·Tian Guan·Cheo Ren": The blister palm is divided into six animals, six beasts, and six birds to identify their names. All things that are dead, alive, fresh and dead will be eaten by the king, and things that are recommended and shameful will be eaten by his descendants and princes. After this passage, Zheng Xuan of the Eastern Han Dynasty noted: "The recommended things are the meals of the four seasons, such as the fish in Jingzhou and the crab cakes in Qingzhou." What is "crab cakes"? Jin Luchen's "Zi Lin": "Xu, crab sauce." This kind of crab sauce is made from sea crabs and is very delicious.
Crab Xu is the earliest crab-eating species recorded by ancient people in historical data. Because sauce was quite popular in the diet at that time. It can be seen that the ancients started eating crabs from the crab skin. Later, with the continuous development of materials and cooking technology, eating crabs has also undergone great changes. The ancients did not just eat crabs. There are more ways to eat crabs, and famous crab dishes are constantly appearing.
During the Wei, Jin, Southern and Northern Dynasties, the famous crab dish "Deer Tail Crab Roe" was produced. Then came the famous crab dishes such as bad crab and sugar crab. This is how Lu You of the Song Dynasty sang about crabs: "Old friends have been forgotten for a long time, and young masters have only enjoyed each other for a long time. They are drunk to death and have no regrets. It seems that they are heartless."
Sui Dynasty Period , there is a famous dish called "Golden Dragon and Phoenix Crab". According to "Qingyilu", this dish is made by pasting dragon, phoenix, flower and cloud patterns carved with gold foil on the shells of bad crabs and sugar crabs. According to legend, this luxurious and famous crab dish was created by Emperor Yang of the Sui Dynasty. Sugar crab was also a famous product in the Sui Dynasty. "Qing Yi Lu" records that "Emperor Yang of the Sui Dynasty was lucky enough to visit Jiangzhou and Wuzhong paid tribute to sugar crab." By the Tang Dynasty, sugar crab was even more popular, and later this crab dish was served as a tribute. Huang Tingjian once wrote a poem: "Sea delicacies are made with sugar to reduce fat, river mashes with termites are alcoholic". Su Shunqing also said: "Frost Mandarin Sugar Crab is so delicious that it makes you realize that everything in your life has gone wrong?"
In the Song and Yuan Dynasties, the famous crab dish was "hand-washing crab". According to records in "Tokyo Menghualu" and "Crab Book", the preparation of this dish is to wash live crabs, pickle them with salt, wine, ginger, orange peel, pepper and other seasonings, and then eat them after washing your hands. According to "Old Wulin Stories", when the queen returned to the province, the emperor gave her fourteen banquets (only one less than the emperor's own banquet, to reflect the difference between the emperor and the empress), and the tenth banquet was "hand-washing crab". It can be seen that "hand-washing crab" was already a famous dish in the palace at that time.
There was also a famous crab dish in the Song Dynasty: "Crab Stuffed with Oranges." "Shan Jia Qing Gong" records that the method of making "Crab Stuffed Orange" is: pick the crab meat and put it into hollowed oranges, put it into a steamer, and steam it with wine, vinegar and water. Serve with vinegar and salt. This dish was also a famous dish in the palace at that time. According to "Old Wulin Stories", when the queen returned to the province, the eighth of the fourteen dishes given to her by the emperor was "crab stuffed with orange".
Crab balls during the Ming and Qing Dynasties are also famous crab dishes for a long time.
According to the "Shi Xian Hong Mi" written by Zhu Yizun in the early Qing Dynasty, crab balls are made as follows: take crab meat, add minced ginger, egg white and other seasonings, and steam it in a bamboo tube.
The ancients ate crabs. In addition to the famous crab dishes recorded above, there were also casual "rough eating" among the people. There are records that during the Wei and Jin Dynasties, there were Jin people who held crab claws to eat crabs. "Shishuo Xinyu·Ren Dan" records: Jin Bizhuo (also known as Maoshi) was addicted to alcohol. He once said: "Holding a wine glass in his right hand and a crab claw in his left hand, he spent a lifetime swimming in a floating wine boat."
The crab-eating culture of "holding a wine glass in the right hand and a crab claw in the left hand" has influenced the crab-eating of the ancients since Bi Zhuo in the Wei and Jin Dynasties. This kind of crab eating is regarded by literati as an elegant and leisurely taste. This interest later developed into eating crabs, drinking wine, admiring chrysanthemums, and composing poems, which became a romantic affair in the golden autumn. Lu You's poem said: "The crab fat has been chewed for a while, and the saliva has fallen, and the wine and green wine have made the old eyes bright." When "A Dream of Red Mansions" describes the crab feast in the Grand View Garden, peeling the shells and eating crabs is also regarded as fun. For example, "Sister Feng gave the peeled crab meat to Aunt Xue, but Aunt Xue refused and said, 'We will take it and eat it ourselves.' In "A Dream of Red Mansions", when eating crabs, Baoyu also said, "Let's write poetry." "So everyone chose a topic while eating and drinking, first chanting about chrysanthemums, and finally chanting about crabs. Xue Baochai's crab chanting always goes like this: "Sitting in the shade of cinnamon and apricots, raising a cup, Chang'an salivates in anticipation of the Double Ninth Festival. The road in front of me has no longitude and latitude, and the spring and autumn sky in the skin is black and yellow. Chrysanthemum can also be used to prevent the smell of wine, and ginger can be used to prevent cold accumulation. What is the benefit of leaving the cauldron today? The moon is empty and the fragrance of grain and millet remains. "Bringing out the elegance and charm of the crab feast in Grand View Garden.
Among the ancient people eating crabs, it is also worth mentioning the "eight pieces of crab". The "eight pieces of crab" are a tool for eating crabs. According to relevant written records, the person who first invented crab-eating equipment was a man named Caoshu in the Ming Dynasty. He first created three tools: a hammer, a knife, and pliers to deal with hard crab shells, and later developed into the "eight pieces of crab". According to "Kao Chi", eight crab-eating tools first developed in the Ming Dynasty include a small square table, a round hammer, a long-handled axe, a long-handled fork, round-head scissors, tweezers, a drill, and a small spoon, which are referred to as "eight pieces of crab". The "eight pieces of crab" are specially designed for eating crabs. Therefore, they have multiple functions such as padding, splitting, forking, cutting, picking, and holding. Put a crab on a small square table, beat all parts of the whole crab with a hammer, then use round-head scissors to cut off the crab legs and claws, and eat them from the feet up. You must use crab legs and claws to eat. Although the crab legs are slender and small, the moving meat is very delicious. If you don't have a crab leg, you have to squeeze it with your teeth or chew it with your teeth. It is more elegant and interesting than chewing crab legs and claws with your teeth. It is the most reserved among the many methods of eating crabs in ancient times.
"Eight pieces of crab" and "holding a wine glass in the right hand, "Holding crab claws in the left hand" is compared to "Wen eating". "Wen eating" has the fun of "wen eating". It is said that "wen eating" a crab takes an hour. "Eight pieces of crab" eats crabs in During the Ming and Qing Dynasties, it was very popular in Jiangsu, Zhejiang and Shanghai.

Remarks
[Edit this paragraph]

Once they die, these bacteria multiply in large numbers; in addition, crabs have It also contains more histidine. Histidine is easy to decompose and can produce histamine and histamine-like substances under the action of decarboxylase. Especially when the crab dies, histidine decomposes more rapidly. As the crab dies, The longer the time, the more histamine accumulates in the body, and when histamine accumulates to a certain amount, it will cause poisoning.
