The oldest part of a clams shell is the outside part of the hinge. This is because the clam starts at the hinge and grows outwards.
The umbo which is located at the anterior end of the clam
The umbo on a clam is the oldest part of the shell and can typically be found at the hinge of the two shell halves, closest to where they join together. It is usually more elevated and centrally located compared to the rest of the shell. Observing the position of the umbo can help determine the age and growth pattern of the clam.
The mantle is the newest part of the clam's shell. At the edge of the mantel there is a thicker area of muscle which turns into new shell as the clam grows.
No, a clam is not a fish. Clams are mollusks, specifically bivalve mollusks, and are characterized by having a two-part shell. Fish, on the other hand, are aquatic animals with fins, gills, and a backbone.
The hinge ligament is a flexible structure that connects the two halves (valves) of a clam shell at the hinge. It acts as a spring to allow the shell to open and close. When the adductor muscles relax, the hinge ligament helps the clam's shell to open.
The umbo which is located at the anterior end of the clam
The oldest part of a clam is typically its shell, which can provide information about the age and growth of the clam through the growth rings visible on its surface. The soft body of the clam is regenerated and replaced regularly, so the shell is a more reliable indicator of age.
The oldest part of the clam shell is called the umbo. It is the portion closest to the hinge and is found by following the growth rings to their center.

The oldest part of a snail's shell is the center of the coil. When the snail grows, it grows outward
The mantle of a clam protects the clam from sunlight in shelled mollusks, the mantle is the organ that forms the shell, and adds to the shell to increase its size and strength as the animal grows.
This is a bivalve mollusk.
A clam. Or an oyster.
Clams are generally covered by a shell. It is a part of the clam's body, and it can open or close; when closed, it serves the purpose of protecting the clam from predators.
