Snails don't change their shells. Unlike crustaceans, molluscs like snails keep the same shell throughout their lifetime. The shell is formed from secretions from the snails mantle, the flesh under the shell, and some snails (such as the giant African snails kept as pets) can be seen running their mouths along the edge of their shells, to build up another layer on the shells lip.
The stripes that make up the pattern of a snails shell are the result of different compositions of shell material at different times.
it means the snail is afraid, or frightend. Oh, and it also means that the snail is trying to protect itself from whatever "frightend it."
No, a snail grows more shell as it gets bigger. Hermit crabs (which live in the shells of dead snails) however do select bigger and bigger shells as they grow.
