Snails are invertebrates with saliva on their body, a mouth on the ventral side of the head with a toothed tongue inside, a prominent head with 2 pairs of tentacles, and tens of thousands of teeth with a large number of teeth.

The snail has an armored shell, shaped like a small snail, diversified colors, the head has four antennae, the head sticks out when walking, and when frightened, the head and tail retract together into the armored shell, feeds on plants, and lays its eggs in the soil or on trees. It prefers to live in a dark, moist, loose and humusy environment, ambles around by day and comes out at night, is afraid of direct sunlight, is sensitive to the environment, and is widely distributed all over the world.

The snail is an invertebrate, mollusk, gastropod, lung snail subclass, snail family. The shell is generally low-conical, right- or left-handed.

In June and July, when it is hot, it hangs itself under the leaves and rises upward until it dies after the saliva is finished.

The snail is the animal with the most teeth, but their teeth are not "three-dimensional teeth". Despite having tens of thousands of teeth, they can't chew their food. That's because they use their odontoglossum - a band-like structure covered with teeth - to crush food for digestion. Over the course of a lifetime, their tiny teeth slowly wear down and dull and are replaced by new, sharper teeth. The snail defecates close to its breathing holes, called stomata. It will defecate on its own body, leaving the feces on the ground eventually through its gastropods and mucus.
