There is a black bag on the shrimp head, which is the place to put shrimp excrement. It will taste bitter and fishy. Be careful when eating, don't break that black bag.

The shrimp line that people often say is actually the digestive tract and intestine of shrimp, which is excrement, that is, "shrimp excrement", tasteless or slightly bitter. It is recommended not to eat. When shrimp lays eggs, there are many small seeds on its stomach, which are actually shrimp seeds. They are completely edible and nutritious.

Then focus on the shrimp head, basically all the internal organs are concentrated in the position of the shrimp head. I opened the head of the shrimp and saw several yellow tissues inside, that is, the ovary of the shrimp (only for females), that is, shrimp yellow. Besides shrimp yellow, you will also see some green, brown and black tissues, which are the internal organs of shrimp. You'd better not eat them. They taste bitter and contain a lot of heavy metals. In addition, it is recommended not to eat shrimp gills, which is unsanitary, full of bacteria and cold.

The shrimp yolk in the shrimp head is really the essence, but there are a lot of other tissues. Shrimp excrement is not on the head, but on the shrimp line on the back.
