Shrimp line is not as terrible as everyone said in the market, it is the intestine of shrimp. The reason why some of them will be dark is that there are some shrimp excrement left in them.
Although this is shrimp's? Poop? But it's not as terrible as everyone thinks. If it is not removed, it will only affect the taste and will not cause harm to health.
Some very small shrimps don't go to the shrimp line, because there will be very little excrement left in them, and fresh-caught shrimps can also go to the shrimp line. However, if it is shrimp cultured in shallow sea, it is best to remove the shrimp line before eating, so as not to affect the taste.
It is also very simple to remove the shrimp line. If you want to cook boiled shrimp, you can find a small toothpick and insert it into the second section of the shrimp back, so that you can directly pick out the shrimp line.

The reason why some shrimps have black heads is that tyrosinase produces some melanin, which has nothing to do with heavy metals.
