It is dioecious, ovoviviparous, and can reproduce throughout the year.

Snails crawl on the bottom of the lake with their wide feet. The meat is delicious, and the ones with yellow snails (male gonads) are male.

The general name for the genus Snails in the order Gastropodidae in the Mollusca phylum. Endemic to China, it is only distributed in lakes in Yunnan. The shell is large, more than 70 mm high. The shape is conical or pyramidal; the shell surface has spinous or papillary protrusions, or only smooth spiral edges. They are horny flakes.

You can eat eggs inside the female snails, which are small snails. The male ones only have testes, which are white and yellow, and have no eggs.

The snails are dioecious, and the male and female are on the outside. It can also be distinguished by the shape of its antennae. The reproduction situation is the same as that of snails, which are viviparous. The eggs are fertilized and developed in the mother's nursery, and are expelled from the body after they grow into larvae. The difference is that field snails have dozens of embryos per birth, while snails generally only have 3-7 embryos per birth. From this point of view, the reproductive ability of snails is much worse than that of field snails. However, according to statistics, the number of female snails is greater. If there are 100 males, there will be approximately 160 females, so the number of hatchlings will naturally be greater. Moreover, snails reproduce all year round no matter spring, summer, autumn or winter, so their fecundity is not weak.
