Pelecypoda is a class of marine and freshwater molluscs that have compress bodies enclosed by a shell into two hinged parts. Members of pelecypoda class include; mussel, clam, oysters and scallops among others. United Nations Farms
Clams, oysters, and mussels are in the shellfish family, under the subheadings of mollusks and bivalves. Mollusks include abalone and scallops as well as clams, oysters, and mussels. Bivalves are any creature with a soft body that lives between two hinged shells.

The water animal like an oyster whose shell has two parts hinged together is the bi-valve. This includes clams, mussels and scallops.
No, bay scallops are not stingrays. Bay scallops are bivalve mollusks, which are marine animals with a hinged shell, while stingrays are cartilaginous fish belonging to the family Dasyatidae. They have very different biological classifications and characteristics. Bay scallops are known for their sweet, tender flesh and are often harvested for food, whereas stingrays are recognized for their flat bodies and long, whip-like tails.
There are many which might have oval or close to oval shells, but one that comes to mind quickly is the cowry, some of which are nearly perfectly olive shaped (Class Gastropoda, Family Cypraeidae).
A "bivalve" is a mollusk that has a hinged shell divided into two halves or "valves," such as clams, oysters, and mussels.
Scallops have two hinged shells that filter their food from the surrounding water. They have an oversized muscle called the scallop adductor which primarily aids them in swimming short distances.
I'm assuming you mean bivalves. These would be creatures like oysters, clams and other aquatic animals that have a hinged two part shell.
An oyster is an example of a mollusk. Mollusks are soft-bodied animals that typically have a calcium carbonate shell for protection. Oysters are bivalve mollusks, meaning they have two hinged shells.
Bivalves are mollusks with two hinged shells that they can close for protection. They come in various shapes and sizes, and their shells can have different colors and patterns. Bivalves do not have a distinct head or radula but have a muscular foot for movement and feeding.
These are called valves- some molluscs have two and are called BIVALVES, whilst others have three and are called TRIVALVES. The latter are held to be higher up the evolutionary scale. The bivalves are the clams, mussels, oysters and scallops. The adults all have two hinged shells (valves). Some of these animals circulate water carrying the microorganisms that they eat and oxygen for respiration through tubes called "siphons" that they can extend from between the shells on the anterior end so they can stay safely hidden in the mud or sand.
