Crab yolk is an egg cell that has not been excreted by crabs, so only female crabs have crab yolk. The ovaries and digestive glands in crabs are orange and delicious. Crab yolk is not a crab egg. Although its composition is basically the same as crab roe, there are essential differences between them. Crab yolk does contain eggs that have not been excreted, but there are other crab organs, glands, tissue fluids and other substances, not just crab eggs.

Identification of male and female crabs;

It seems that the appearance of hairy crabs is basically the same, and it can't be seen from the shell. It can be distinguished by a simple method, and it can be distinguished by looking at the abdomen of hairy crabs. Moreover, it is a very vivid metaphor that male crabs wear thongs and female crabs wear diapers. In other words, the male crab's abdomen has a fleshy shell, which is sharp and the female crab is round. Another method is to open the shell. If it is yellow, it must be female. If it's white, it's crab paste. It must be male. Male crabs have more meat than female crabs.
