how does a clam swim?
Help please...
Answers
The clam has a pair of very large gills, and the surface of the gills is covered with cilia. The cilia beat in a coordinated fashion, and the movement of the cilia cause water to move into and through the clam. Food-containing water enters through the incurrent siphon and passes over the gills.

How do clams move?
Clams have the most control of their movement using their foot. This foot allows for a certain amount of lateral (side-to-side) movement. However, this foot is most useful for allowing the clam to burrow into the sand. For this reason, the foot is strongest at digging, which allows a clam to submerge itself safely out of harm's way. Aside from digging into the sand, most clams then move by using water currents, which allows them to move from one region to the other. On the other hand, clams do not have a lot of control over how or where water currents carry them.
