A mollusk has a "foot," the body's muscular section, responsible for movement. The foot of some mollusks has also adapted to attaching to rocks and grasping prey.

The photo is the hing line for this type of clam and is also the line of symmetry between both halves. While symmetry is not perfect it is there. Brachiopods have a different symmetry see this link below.

Each valve of Nuculopsis (right drawing, “Bilateral symmetry (clam)”) is nearly a mirror image of the other, so that the plane of symmetry lies along the line at which the valves join, called the line of commissure. This is true of most clams. Brachiopods are quite different. Like clams, the brachiopod lives in a shell consisting of two hinged valves, but the orientation of the shells is different. Brachiopods have valves covering the top and bottoms of the animal that are of different sizes and shapes, but the left and right sides are are symmetrical (or mirror images to each other).Verified answer. chemistry.
