Snails have shells, which are shaped like small snails and have various colors; There are four tentacles on the head. When you walk, your head sticks out, and when you are frightened, your head and tail retract into the carapace together. Snails have saliva, which can inhibit centipedes and scorpions. When it is hot in June and July, it will hang under the leaves and rise upward until it dies after vomiting.
Snails have the most teeth, but their teeth are not "three-dimensional teeth". Although there are thousands of teeth, they can't chew food. This is because they have a banded structure with a toothed tongue covered with broken teeth for digestion. During their life, their little teeth will slowly wear out and become dull.
