Why are there no shells on the beach?
As CO2 levels rise, the water becomes more acidic and the amount of carbonate (needed to make calcium carbonate — the compound that most shellfish and corals use to build their shells and skeletons) decreases. Eventually there is so little carbonate that shells or skeletons don’t form properly or can’t form at all.

Do shells grow with the snail?
Growth of the shell As the snail grows, so does its calcium carbonate shell. The shell grows additively, by the addition of new calcium carbonate, which is secreted by glands located in the snail’s mantle. The new material is added to the edge of the shell aperture (the opening of the shell).
