Starfish eat pretty much anything that's too slow to escape. Many prey heavily on bivalves (mussels, clams, and oysters).
Scallops come from sandy or muddy bottoms of most seas and oceans.

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.
