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.

Some stoves are referred to as clam shells because they resemble the form and function of the shells of a clam. They are compact with hinge joining two halves.

The two valves of a clam are connected by a flexible hinge ligament, which allows the shells to open and close. This hinge is located at the dorsal (top) side of the clam and is crucial for the clam's ability to protect itself and manage its internal functions. Additionally, the adductor muscles, which can contract to close the valves tightly, provide further control over the opening and closing mechanism.
The umbo, also known as the beak, is the oldest part of a clam shell. It is the point where growth starts and forms the center of the shell. Over time, new layers of shell material are added, extending outwards from the umbo.

Bivalve mollusks like clams hold their shells closed with their muscular bodies. They also have leathery "hinges" at the rounded part of the shell which help to hold the two halves together. These are similar to ligaments in higher animals. If you ever get a clam in the supermarket that is already open, that one is dead and you should not eat it.
A clamshell is a one-piece container consisting of two halves joined by a hinge area which allows the structure to come together to close. Clamshells are often made of a shaped plastic material, in a way that is similar to a blister pack. The name of the clamshell is taken from the shell of a clam, which it resembles both in form and function.
A clam shell is typically oval-shaped with two hinged halves that can open and close. It is usually smooth and symmetrical. Clam shells can be distinguished from other types of shells by their shape, hinge, and lack of prominent ridges or spikes.
