1. Hairy crabs live in shallow waters and don't need oxygen all the time. Therefore, the respiratory system of hairy crabs is relatively comprehensive and developed. We call this part the parotid gland, which is the crab cheek. Hairy crabs can breathe freely in water through crab gills. Because it needs filtering, the parotid gland is dirty, and it is also the main area where parasites live, so it can't be eaten. Location: After opening the crab shell, you will see two rows of gray soft tissues, which are crab gills and need to be removed before eating.

Second, the omnivore hairy crab eats everything, except small fish, shrimps and aquatic plants in the water, as well as rotting animal carcasses and microorganisms. So the crab's stomach is dirty and can't be eaten. Location: Open the crab shell. There is a triangular black thing in the crab yellow area, which is the crab stomach. Take it off when you eat it.

Third, the crab heart, commonly known as the hexagonal plate, grows in the middle of the crab yolk of the hairy crab and is connected with the crab stomach. When eating crab roe, it is easy to eat the crab heart together, and the crab heart is not very clean. This is one of the main areas where parasites live. It's too cold to eat. Location: You can see a layer of black film when you open the crab shell. The white flaky crab heart is between the yellow paste and the black film, so you should throw it away when you eat it.

Fourthly, the crab intestine contains the excreta of hairy crabs, which is the pipeline connecting the crab stomach and navel. Generally, the crab shell will be removed directly when it is removed, but it will also be pulled off during the extraction process, resulting in some crab intestines remaining in the crab roe, which needs to be removed before eating. Specific location: after breaking the crab, I saw a black tube at the crab yellow and crab meat.
