In fresh water, there are common Chinese round snails, Chinese round snails, etc.

The difference between snails and snails is that they have different species attributes, different distribution and origin, different shell styles, different size and different living habits.

1. The types and attributes are different

Field snail generally refers to the mollusk of the field snail family, which belongs to the field snail family of the subclass Gastropoda of the phylum Gastropods. The snail is the common name of the square ring snail, which is the whole of the square ring snail of the field snail family or other rock objects belonging to the same genus. Also known as square snail.

2. The distribution of origins is different

Snails are found almost everywhere in the world. The snail is not found all over the world like the snail, but a special product of our country, which is only produced in various lakes in Yunnan Province, the southwest plateau of China.

3. The shell style is different

The shape of the snail is similar to that of a snail, and it also has a right-handed spiral-shaped shell. However, the surface of the snail shell is not as smooth as that of the snail in Tianlaozhen, and there are many spiral-shaped ribs on it. The ribs form spines or bead-like protrusions, and the shape varies depending on the species.

The shell of a field snail has no ribs on it.

4. The size is different

Snails can grow slowly. It usually grows to the size of grapes, even walnuts. Snails generally don't grow much.

5. Different living habits

The snail lives prostrate at the bottom of the water (lake) and must be caught with a special trawl net. Snails are found in Dianchi Lake, Erhai Lake, Yang Zonghai, Yilong Lake, and Fuxian Lake in Yunnan Province, unlike snails, which can be collected on the shore or in paddy fields. Snails prefer to live on the shore or in paddy fields.

There are more than 70 species of snails known in China <>, among which the more common ones are: Chinese round snails, snails, ear snails and Fushou snails. The body of snails is divided into five parts: head, feet, visceral sac, mantle and shell.
