Oysters and mussels do not shed their shells. They are bivalve molluscs and their shells grow larger with age.
Molluscs extract calcium carbonate from seawater to build their shells. They secrete this mineral to form the hard outer layer that protects their soft bodies.

Many molluscs, such as snails, and also creatures like turtles and tortoises have shells.
Gastropods, or slugs and snails, as opposed to molluscs with two shells which are bivalves.
Some mollusks live in shells made of calcium carbonate, but they do not have exoskeletons like insects do.
One class of molluscs that lacks a radula is the Bivalvia, which includes clams, mussels, and scallops. Instead of a radula, these organisms have two shells that they use to filter feed. They do not require a radula for scraping or grazing on food sources like other molluscs.
The limpet has only one shell, making it a univalve. Molluscs with two shells, such as clams and mussels, are bivalves.
I think you´re looking for molluscs - snails and the like.
only if a turtle counts to 5 Real answer, no they aren't. Shells are made of minerals such as calcium, which molluscs derive from thei environment. The only shells that could be classed as rock aren't really shells at all but fossilised remains of them- fossils being the imprints left behind in sedimentary rocks by prehistoric animals and plants after their real remains have rotted away.
