The internal organs of crabs are mainly understood as four things: crab stomach, crab cheeks, crab heart and crab intestines, which are inedible. Remember to pick out hairy crabs when you eat them, because they contain bacteria, viruses and sludge, which is called "four don't eat" for short. Last year, I mentioned a picture on the crab ticket attached to Yangcheng Lake hairy crabs in Su Zhang Crab Museum:

1 crab stomach-crab stomach, commonly known as crab monk and crab urine bag, is wrapped in the middle of crab yellow and looks like a small triangular black block.

2 Crab gills-Crab gills, commonly known as hairy crabs and crab eyebrows, are the respiratory organs of hairy crabs. On both sides of the front of the hairy crab, there are two rows of soft things like eyebrows.

3 crab heart-crab heart, commonly known as hexagonal plate, is located in the middle of crab yellow, next to the crab stomach.

4 crab intestines-the crab intestines are located in the middle of the crab navel, showing a strip shape, and there is a black line from the crab stomach to the crab navel.
