The hinge ligament is attached to the adjacent edges on one side of the two halves of a clam shell. This allows the clam to open and close like a door.
Bivalves are mollusks with two shells, such as a clam. A univalve is a mollusk with one shell, such as a snail.
the mussel of the clam keeps the shell together. But they can open it if the want.
The shell of a clam consists of two valves hinged together along the dorsal side (front). On the opposite end of where the clam opens is a swollen region (the umbo) where the shell of the clam starts to grow.
The clam can survive with only 3 pairs of ganglia. Two pairs control the open and closing of the shell, will the pedal controls the foot of the clam.

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.
The mantle of the clam lines the valves, and serves to secrete calcium carbonate in the formation of the clam's shell while protecting the clam's visceral mass.
A clam is a bivalve mollusc-that is one with a shell that splits in two. Octopus are also molluscs but of the cephalopoda class-this means they are bilaterally symmetrical-only symmetrical in one direction.
