this ~ ~ ~ ~ your question is wrong. These two things are completely different, and the difference is too much.

Aolong refers to lobster, which is short for Australian lobster. The big one, with a big head and a small belly, is curved.

people in the north call crawfish tiger, while people in the south call it Sartorius shrimp. They are generally more than ten centimeters long and have a flat body. You can see the picture by searching Baidu.

There are many kinds of lobsters. Generally, there are red dragon, green dragon, flower dragon and Australian dragon in the market. Among them, red dragon is the cheapest, with dark red skin and big body, but it tastes the worst. Tsing lung has a bluish-black skin, a big head and a small body, a transparent flesh color and a good taste. The skin color of Hualong is similar to that of Qinglong, but the pattern is obvious and colorful. Australopithecus is generally small in size, big in head and small in body, translucent in flesh color and most delicious in taste. Therefore, Aolong is the most expensive, generally more than 1 kg in 26 yuan, while Red Dragon is much cheaper, less than 1 kg in 2 yuan.

Crawling shrimps, that is, shrimps and tigers, are generally twenty or thirty yuan a catty, with different sizes. Generally, a catty is only about a dozen ~~

Do you think there is much difference?
