The Pacific geoduck “gooey duck”, is a very large, edible saltwater clam. The common name is derived from the Lushootseed word gʷídəq.
The geoduck is native to the west coast of North America. The shell of the clam ranges from 6 inches to over 8 inches in length, but the extremely long siphons make the clam itself much longer than this: the “neck” or siphons alone can be up to 3.3 feet in length. The geoduck is the largest burrowing clam in the world. It is also one of the longest-living animals of any type, with a lifespan of up to 140 years; the oldest has been recorded at 168 years old.
