Among them, the hairy crabs produced in the lower reaches of the Yangtze River, such as the Taihu Lake hairy crabs, Gaoyou Lake hairy crabs, and Yangcheng Lake hairy crabs, are the best. In addition, blue crabs and river crabs are also common in our lives. I have compiled the following most common crab species and names.

1. Blue Crab

The blue crab is also called the serrata blue crab. Its shell is very hard and oval, which looks a bit flat. Its chest is very strong and its two claws are very hard, like a paddle, so some people call it a paddle. At present, the price of blue crab is about 110 yuan per kilogram.

Red crab is also called cross crab. Its cephalothorax is also very wide, its surface is relatively smooth, its claws are relatively strong, the front of the second finger is dark brown, and the claws have yellow markings, which makes it very recognizable. The price of crab is relatively moderate, averaging about 49 yuan per catty, and it has always remained at a relatively low level.

7. Red Crab

The red-shelled sea crab is a type of sea crab. Because its abdomen and leg edges are slightly red, it is called red-shelled or stone-shelled. The male flying crab costs 10 to 15 yuan, and the female costs 30 to 40 yuan. The price of the red-shelled sea crab is basically 1.5 times that of the flying crab. Of course, this is the normal palm-sized one. The super-large ones are very expensive.

8. Swimming Crab

Swimming crabs, also known as "white crabs" in some places, are fat and delicious, with high nutritional and economic value, and suitable for temporary fattening in seawater. A 5-liang swimming crab costs 45 to 50 yuan per catty, a 3-liang one costs 25 to 30 yuan per catty, and a smaller one costs only 18 to 20 yuan per catty.

9. King Crab

King crab, also known as stone crab or rock crab, is a crustacean of the family Crabidae. It is not a real crab and is mainly distributed in cold waters. It is named for its huge size and is known as the "king of crabs".

10. Dungeness Crab

Dungeness crab is a kind of crab produced in the United States. It is named after a small town in Washington State. A live Dungeness crab costs 228 yuan per pound, which is close to 1,000 yuan per crab. The price in the supermarket where it is produced is 10 dollars per pound. The domestic cooked and frozen ones cost dozens of yuan, and the fresh ones cost at least 100 yuan. This is the port, and it is more expensive inland. In addition, the purchase price of Dungeness crab is almost the same, but the final price on the table is very different. The price in the hotel is as low as 158 yuan per pound, and the expensive one costs more than 800 yuan per pound.

Types of crabs include swimming crabs, king crabs, blue crabs, brown crabs, tiger crabs, jade crabs, hairy crabs, etc.

Extended content: Different types of crabs have different origins and water qualities.

1. Swimming crabs are rich in meat, fat, delicious and nutritious. Every 100 grams of crab contains 14 grams of protein and 2.6 grams of fat. Fresh crabs are mainly steamed, and can also be salted to make "choked crabs" and crab sauce. Crab eggs are rinsed and dried to become "crab roe", all of which are top-grade seafood.

2. King crabs are also known as stone crabs or rock crabs. They are mainly distributed in cold seas. They are named because of their huge size and are known as the "king of crabs". The preciousness of king crabs lies in their plump and tender crab legs. The tender taste is delicate and the sweet taste is really memorable. Crab meat is high in protein, low in fat and calories, contains a variety of minerals, and is rich in unsaturated fatty acids. It is a top source of protein.

3. Blue crabs are delicious, nutritious, and have the effect of nourishing and strengthening the body. Especially for female crabs that are about to get pregnant, red or yellow paste will be produced in their bodies. This is called "paste crab" in southern China and is known as "sea ginseng". Blue crabs are abundant in warm shallow seas and are mainly distributed in coastal areas of Zhejiang, Guangdong, Guangxi, Fujian and Taiwan in China, especially in Jiangsu and Zhejiang. Nutritional analysis Blue crabs are rich in protein and trace elements, which have a good nourishing effect on the body.

4. The king crab is the most friendly one in the crab family. It has a flat and fat body and often lives in deep sea water with a temperature of 11℃. It walks leisurely and calmly. It likes to stay in one place and store crab roe, so it is also called a sleeping crab. Looking at it, you can't help yawning. The chef said that it is the only crab that does not need to be pierced with crab claws because it moves slowly and has no attack power at all. It is said that this kind of crab has the most roe in the world. Its roe is so rich that it covers the entire crab shell. Although the crab flavor is not too strong, it has a unique fragrance. The crab meat of the king crab is thin and white, and it has the salty taste of sea water. It is very refreshing to eat it alone. The crab roe is like ice cream, which is quite soft and smooth.

5. Tiger crabs were originally called "coffee crabs" or "Royal Concubine Crabs". Most of these crabs are found in the Philippine waters, and are also found in some waters in southeastern China. They are so named because the texture and color of their shells resemble tiger skin. They have full and delicious meat. They are eaten in a similar way to lobsters, and are best cooked with soup or cheese.

There are many kinds of crabs. There are about 600 kinds of crabs in my country, including swimming crabs, blue crabs, frog crabs, Guan Gong crabs, etc. Due to different geographical distribution, there are also grades. The first grade is lake crabs, such as Yangcheng Lake and Jiaxing Lake; the second grade is river crabs, such as Jiujiang and Wuhu; the third grade is river crabs; the fourth grade is stream crabs; the fifth grade is ditch crabs; the sixth grade is sea crabs. Crabs have the most aliases. In "Dream of Red Mansions", Jia Baoyu called it "the man without intestines" in his poem; in "Journey to the West", it is called "the horizontal Jieshi"; when Lu Chun, a Tang Dynasty scholar, evaluated the delicacies of the world, he said: "Among the flavors of the four directions, Xu Hanhuangbo is the best." He was also talking about crabs.

There are many varieties of crabs, with a total of more than 600 species. Among them, the more common varieties are hairy crabs, king crabs, flower crabs, red crabs, blue crabs, treasure crabs, sand crabs, crystal crabs, brown crabs, stone crabs, giant crabs, etc. According to their living environment, they can be divided into sea crabs and freshwater crabs. Among them, flower crabs, blue crabs, swimming crabs and other varieties live in the sea and are sea crabs. However, hairy crabs, crystal crabs and other varieties can live in fresh water and are freshwater crabs.

1. What are the types of crabs?

Crabs belong to the order Decapoda, class Soft Shell, phylum Arthropoda, and are a relatively common animal. There are many varieties of crabs, with a total of more than 600 species. We have heard of or seen many kinds of crabs, such as hairy crabs, king crabs, flower crabs, red crabs, blue crabs, treasure crabs, sand crabs, crystal crabs, brown crabs, stone crabs, giant claw crabs, etc. The differences between these different varieties of crabs are relatively large, and there may be great differences in body shape, distribution waters, and appearance.

2. What are the common species of crabs?

1. King crab: King crab is also called "king of crabs" because of its large size. In terms of distribution, king crabs are distributed in very deep sea water, with a depth of up to 850 meters. They can live in very cold waters.

2. Flower crab: Flower crab is a crab with patterns on its shell, hence its name. From the perspective of distribution, flower crabs have high requirements for water temperature and are a species that lives in warm water. Flower crabs are distributed in some southern provinces of my country, such as Zhejiang Province, Taiwan Province, Guangdong Province, Hainan Province, etc.

3. Brown crab: It is also called "steamed crab". This crab is relatively small in size, with a shell length of only 6-7 cm and a width of only 8-9 cm. This crab is most widely distributed in the Pacific Ocean, and is distributed at a depth of 30-100 meters.

4. Giant claw crab: This species can be said to be the largest type of crab, and even the largest type of crustacean. Its shell length can reach 38 cm and its weight can reach 20 kg. In terms of distribution, this crab also mainly lives in the Pacific region, and is more common around Japan; the distribution depth is between 50-300 meters. Because this crab is very large, it sometimes even eats very large animals such as sharks.
