The most obvious difference between snails and slugs is the fact that snails have shells. A snail’s shell is like a home it carries around on its back. Slugs, on the other hand, have no shell. Without those big shells to carry around, slugs can squeeze themselves into many different habitats that snails can’t.
Why do I find empty snail shells?
When you find what appear to be empty shells lying on the ground, they are usually indeed empty; the snail has died, and scavengers have eaten the remains. Living snails resting on or just under the ground usually seal the mouth of the shell with a sheet of dried mucus, called the epiphragm.
Can a snail shell repair itself?
If this shell becomes significantly broken then the snail will probably die. Whilst snails can repair small cracks and holes in their shells, if the break is serious then they will struggle to survive as the shell not only provides protection but also prevents them from drying out.
Can a snail become a slug?
