Geoduck is a large, unusually shaped clam that is native to the west coast of North America, namely Pacific Northwest and Western Canadian coast. It consists of a long soft body, often referred to as a neck or siphon, which hangs from the shell, and which may reach up to 3.3 feet (1 m).
With a small foot, these clams bury themselves in the ground, and they remain at the same place for the rest of their lives. As a culinary ingredient, geoduck is an expensive delicacy. It is usually just shortly boiled before it is eaten. The shell is removed, and the skin that covers the trunk is peeled off.
