There are two answers. 1. The inside of the crab is black, if the crab is opened, there is a black membrane coating on the inside of the crab shell and the shell, which can be eaten; 2. If the black thing inside the crab is located in the middle of the crab, wrapped in crab roe, and in the shape of a triangular bag, the crab stomach in the middle of the crab cannot be eaten.

1. Black membrane before the crab molts: it can be eaten.

If the crab is opened, there is a black membrane coating on the inside of the crab shell and the shell, then the black membrane is edible.

Because this layer of black membrane is actually the shell of the crab that has not yet grown, generally the crab will molt when it grows to a certain extent, and the black membrane coating inside will become thicker and thicker as the crab grows, and when the hard shell on the outside of the crab is detached, the black membrane coating becomes a soft shell, and it will also become a hard shell over time. Therefore, what can be eaten in this black membrane is high in protein and calcium.

2. The crab stomach in the middle of the crab: it cannot be eaten.

If the black stuff inside the crab is located in the middle of the crab and is wrapped in a crab roe in the shape of a triangular bag, then this may be the crab's stomach and cannot be eaten. Crabs feed on small aquatic organisms, aquatic plants and decaying animals, so the crab stomach is very dirty and cannot be eaten.

When the crab rises to a certain extent, it has to take off a layer of armor, that is, the shell, the longer you say, the thicker the black membrane coat becomes, and when the outer hard shell is detached, the black membrane coat becomes a soft shell, and it will also become a hard shell over time. So it's edible, it's something high in protein and calcium.

Anything can be eaten.
