Old Snail Shell, a broken home
I don't know a lot about snails, other than that they are usually quite slimy but their shells are composed of calcium carbonate and as the snail grows, so does the shell. Snails that have shells will close off a section of its shell and add a new chamber as it grows, each one being larger than the previous by a constant factor, as a result, the shell forms a spiral.
The shell of snails and other molluscs are, as I said, composed of calcium carbonate, and because of that they need a somewhat watery environment to get the calcium in their diet, so as to produce a strong shell. A lack of calcium or a low pH in their environment, can cause thin, cracked, and perforated shells. Usually they can repair this but sever damage can be fatal.
Snails can be found in a wide variety of places and some are edible and those can usually be found in Burgandy!
