The one with seeds is a female. Just turn it over and there will be a word "王" on the neck. If there are no seeds, the male will have three horizontal lines.

The method of peeling the skin of shrimps is as follows:

1. The skinned shrimps have barbs. When holding the shrimps, they should be with their heads up and their tails down, so that they will not Caught by shrimp spines.

2. Remove the head.

3. Remove the gastropods. This is very important, because there is a tendon in each gastropod connected to the shell on the back. Therefore, many times, when we peel the shrimp, we just open the shell. The shrimp meat inside has already fallen apart. This is because we did not tear off the abdominal and foot tendons first.

4. When we finish peeling the shrimp meat and look at its back shell, we can see that inside each ring of shrimp shell, there are two protrusions in the middle. These two protrusions are directly connected to the ventral legs. The shrimp can move because of its tendons. This can also be regarded as its physiological characteristics.

5. Remove the long thin legs under the shrimp head and its shell.

6. Remove the tail legs and tear open the shell from where the toothpick points.

7. Then tear off the shrimp shell on this side from where the toothpick points. Pull it all apart.

8. This is how the shrimp shell on one side looks like it is all open.

9. In front of the tail, pull open the other side,

10. Pull the shrimp tail out of the shell.
