As a native of the seaside, it is a common thing to eat seafood. My family lived by the sea since childhood, and there was a boat at home at that time, so it seems that there is no shortage of seafood on the dining table at home. This is what we are used to, but it seems to be enviable to our friends in the inland. I think it is seafood to eat seafood fresh, so people who live by the sea are really happy.

There are also many kinds of seafood. I remember my favorite when I was a child was to go to the seaside to catch the sea with my mother. The rocks on the seashore were covered with oysters. Our place is called oyster. In fact, the scientific name is oyster. One side of the shell of oyster was pried open with a small stone, and then the meat inside could be eaten raw. Now it can't be, because many sea areas are polluted and oysters can't be eaten raw, but it is too delicious to take home to make soup.

Later, when I grew up, I never went to catch the sea again. I wanted to eat oysters. The price of oysters was not cheap, but it was understandable, because catching the sea was really hard. But did you find that there were two kinds of seafood in the market, oysters and oysters? Even people who had eaten seafood for 30 years knew that there was a big difference between oysters and oysters.

Today, I will share with you how to distinguish between oysters and oysters. Don't be silly and confused when you know it. Let's take a look at the specific differences.

The first difference: variety

In fact, oysters and oysters look very similar, but they are two different kinds of seafood. In fact, oysters are a kind of oysters. There are many kinds of oysters, and oysters are one of the better ones. So some people say that oysters are oysters, which is wrong.

The second difference: appearance

If you look closely, you will find that the appearance of oysters is different from that of oysters. The surface of oysters is uneven and the color is gray, which looks like a stone. The surface of oysters is also rough, but the lines will be smaller, mostly black in color and smaller in size; Two shells are also big and convex, and one is small and flat, which looks like a triangle.

The third difference: the growing environment

Oysters have low requirements for seawater temperature and environment, so they are produced in many sea areas. Oysters, on the other hand, like the cold sea water, and they must be cultivated in a shallow bay that is half salty and half light or at the intersection of rivers and oceans. Oysters pay great attention to the "environment of origin", and different environments make the meat taste different, so the top "Peron Oyster" can have the reputation of "the king of oysters in the world".

The fourth difference: nutritional value

Because of its long growth cycle, oysters are very rich in nutrition, including 7 times of zinc and 40% of protein. The advantage of oysters lies in their high calcium content, which is about 4 times that of oysters.

The fifth difference: price

Because of the long growth cycle of oysters, they are generally sold by the weight, especially imported oysters, which are expensive, while oysters are usually sold by the weight, and the price is relatively cheap, usually 4~5 yuan a catty.
