If you want to tell whether a crab is a male or a female, you can also look at the crab's belly. The lower part of the crab's belly is triangular, that is, the male crab, while the lower part of the belly is round, that is, the female crab. This kind of crab can be purchased with confidence, which will definitely make people eat more crab roe.
2. Look at the umbilicus
When a crab is divided into a male and a female, you can look at their umbilicus. The umbilicus of a crab is a small cover near the lower part of its belly. If this small cover is pointed, it means that this crab is male. If this small cover is round, it means that this crab is female.
3. Watch your legs
You can also tell their male and female by looking at their legs. The female crab's legs are different from those of the male crab, which only has fine fluff on the front two legs, while the male crab is different. There are fluff on their eight legs, which is the simplest and most convenient way to distinguish the male and female crabs. People can tell them with their eyes.
