When shells of clams and oysters accumulate on the seafloor, they can form a type of sedimentary rock known as limestone. Specifically, if the shells are primarily composed of calcium carbonate, they may become calcitic limestone as they undergo lithification through compaction and cementation over time. This process transforms the accumulated organic material into solid rock, often containing fossilized remains of the original organisms.
crabs live in shells. so do clams, oysters, and scallops
Their shells grow as the organism grows
Oysters create their shells from calcium carbonate and proteins secreted by their mantle tissue. This process occurs continuously throughout their lives as they grow, producing layers of shell material to protect their soft bodies.
clams, oysters, or mussels
Oysters and mussels do not shed their shells. They are bivalve molluscs and their shells grow larger with age.

oysters make shells
No. Oysters are mollusks, which have shells rather than bones.
Oysters live in the water, and thus have an abundance of water. They die if they dry up, but can conserve water by closing their shells.
The oyster-catcher!
The oyster's shell provides protection from predators. Oysters do not need to shed their shell because the eat and expel waste products buy opening their shells and pumping water in and out with hairlike structures call cilia.
they all have hard shells and live in the ocean
