Why do Yangcheng Lake hairy crabs still move after being placed in a sealed foam box for two days?

It shows that the packaging is good and the hairy crab is very fresh, ***. Hairy crabs breathe with their gills, which are hidden under their jackets like a sponge and can absorb a lot of water, and they can live on land by relying on the water in their gills. The flow of water in the gills is drained of oxygen and flows back into the body from the bottom of the chelicerae.

As the water flows through the body, fresh oxygen melts in. So hairy crabs can breathe as if they were in the water. But over time, the water in the cheeks will gradually decrease.

At this time, the hairy crab will twitch its mouth and gills in an attempt to absorb water, but it will suck in a large amount of air, and the air will mix with the water in the gills and form some bubbles.

Therefore, some hairy crabs have sludge and some growing dirt on them, so you must use a brush to scrub the hairy crabs well before steaming.

Hairy crabs live at the bottom of the water, and there are more ditches and ditches on the surface of the body, so it is easy to breed and leave some things, so they should be cleaned before cooking.

This depends on where you buy it from, if you buy it directly from the farmers, the general farmers will not wash the hairy crabs very cleanly. On the contrary, it is the secondary market, such as store merchants will wash hairy crabs in order to improve the service value of hairy crabs.
