Why did the dead crab disembowel and take pictures?

The reason why dead crabs have to be taken photos is to show their meat quality to customers. The crab may have died when it was caught, but because of its special body structure, it opens its belly like a bag, and then its meat quality and texture can be seen. Therefore, in order to show customers the meat quality of crabs, photographers will pat the crabs with their bellies open. In addition, patting open the belly of a dead crab also helps to distinguish between dead crabs and live crabs and confirm the exact species of crabs.
