Seashells contain calcium carbonate. The calcium carbonate reacts with the acid in the vinegar and causes carbon dioxide bubbles to form. Even though the acid in vinegar is weak it can, over a period of time, dissolve shells.
Although its shell is attached to it, it's not part of the living body of a mollusk. This is because the shell is formed from minerals, not mollusk cells. As mollusks continue to excrete calcium carbonate, their shells continue to grow. When a mollusk dies, it leaves its shell behind for you to find along the sea shore. A mollusk 's shell material, called nacre, is mostly calcium. However, it also usually has an outer layer of hard scleroprotein, which is similar to human fingernails. There are many different types of mollusks. Moreover, different seas around the world offer mollusks all sorts of different diets.
