The crab yolk is unique to female crabs, and male crabs do not have crab yolk; the part of the male crab that corresponds to the yolk of the female crab is the white crab paste.

The crab yolk is not the crab's egg, but it is indeed the ovary and digestive glands and other tissues in the crab's body, and it also contains egg cells that have not been discharged from the body. When the crab is steamed and the shell is opened, the yolk appears orange and bright in color, which indicates that the gonads of the female crab have matured.
