Simplified etymology

Clam originally meant “a bond” or “something that holds tight” in Old English and later “a clamp”; it probably shares its source with clamp. The shellfish name appeared in the early 16th century, apparently referring to its tightly closed shell. A separate dialect verb clam, “be sticky” or “stick,” is related to clay and gave rise to clammy; the phrase clam up is usually linked to the shellfish, though an isolated example from about 1350 may instead reflect the sticky sense.

Etymology

From Middle English clam (“pincers, vice, clamp”), from Old English clam (“bond, fetter, grip, grasp”), from Proto-West Germanic *klammjan (“press, squeeze together”). The sense “dollar” may allude to wampum. The sense "Scientologist" alludes to the Scientologist belief that human thetans (souls) previously inhabited clams.
