As the weather gets hotter and hotter, the season of eating crayfish has come. Now more and more people begin to see crayfish on the table at home. Although crayfish is called lobster, you should never confuse it with real lobster. Let's learn about the difference between crayfish and lobster.
The difference between crayfish and lobster

Lobster is seafood, which mainly inhabits the ocean, while crayfish actually belongs to river fresh and generally lives in ditches and ponds.
3. Price difference
The price of lobster is higher than that of crayfish. Generally, the quotation is more than 100 yuan or even higher. According to different specifications, the price of crayfish is cheap and expensive, but it will not exceed 100 yuan a catty.
When is the best season for crayfish?
Crayfish is best eaten in summer.
The content of protein in crayfish is very high, and the meat is soft and easy to digest. The shrimp meat is rich in magnesium, zinc, iodine and selenium.
However, crayfish is a high-protein food, so people who are allergic to protein should be careful to avoid allergic reactions.
Where can I eat crayfish?
Crayfish can be eaten in other parts except the head, intestines and shrimp yellow.
Parts that crayfish can't eat:
1, head
Because the head of crayfish absorbs and processes the most toxins, it is also the part that easily accumulates pathogenic bacteria and parasites.
2. Intestines
The digestive system of crayfish, such as intestine, tends to accumulate heavy metals, so it is necessary to pull out the shrimp line before eating it when cooking.
3. Shrimp yellow
If you don't know whether the shrimp is clean or not, eat less shrimp yellow.
Shrimp yellow is the gonad of lobster, which is close to the liver and is easily polluted.
Illness occurs after eating.
Although we usually see people eating shrimp heads in many videos, it's okay, but this depends on the specific situation. On the whole, it is not recommended for everyone to eat. The "yellow" in shrimp heads is neither shrimp eggs nor shrimp feces, but the hepatopancreas of crayfish, that is, the liver and pancreas, which are easy to be polluted. It is best not to eat it.
