One of the most recognizable characteristics of snails is having a shell. In general, we know that the snail is a shelled animal. Apparently not all snails have a shell. In English, a snailed snail is called a snail, while a non-shell is called a slug. Both are equally sheltered in the class Gastropoda.
Snails can be found in a variety of different environments: from moat to desert, even to deep sea and many also live on land.
Now I learn how the snapshot is not shelled, so the result is still less detail and good.
