This is a ribbed shell snail among snails. It's hard to say whether you can eat it or not. It depends on the growing environment, food, etc. The reason is as simple as "growing up with poison, do you think it may not contain poison?" Therefore, it is generally recommended not to try (eat) casually. Or you can consult local residents. If they eat regularly, you can also try to eat. Try to be careful of bitter taste, and never eat more or eat more. Because bitter snails are rich in harmful substances, eating too much will kill people.
