Symmetry of a clam.

Clam. Clam is a common name for several kinds of bivalve molluscs. The word is often applied only to those that are edible and live as infauna, spending most of their lives halfway buried in the sand of the seafloor or riverbeds. Clams have two shells of equal size connected by two adductor muscles and have a powerful burrowing foot.

A clam’s structure is called “bilateral symmetry,” meaning two sides are mirrored halves.ᅟ Symmetry is an eye-catching feature of animal body plans, yet its causes are not well enough understood. The evolution of animal form is mainly due to changes in gene regulatory networks (GRNs).

Clams have a two-part hinged shell that is open at one end. The clam’s body is inside the shell, and its foot is extended outside the shell.A clam's shell is it's symmetry. when the clam opens up it's shell each side of the shell is equally the same on both sides. This is what is called symmetry.

The median sagittal plane, including the axis of symmetry, is the plane of symmetry that divides the worm into mirror image right and left sides (Fig 9-1A). The worm consists of a small anterior prostomium, a tiny posterior pygidium, and a very long segmented trunk between the prostomium and pygidium (Fig 13-1, 13-6).
