The shell that can open and close is typically associated with bivalve mollusks, such as clams and oysters. These shells consist of two hinged parts (valves) that can be opened to allow the organism to feed or breathe and closed for protection against predators and environmental threats. The opening and closing mechanism is facilitated by a group of muscles that control the shell's movement.

How is the hinge ligament in relation to the two halves of a clam?

How does a clam open and close the shell?
Clams close their shells with powerful adductor muscles which pull the two valves together. A springy ligament at the hinge pulls the shell open when the muscles relax. Just like us, the clam needs to use nerve cells to signal the muscle to do its thing.

Is a closed shell or open shell in chemistry more reactive?

Closed shell compounds have all electrons paired and are generally more stable and less reactive.
