The
geoduck (pronounced "GOO-wee-duck") is not a
duck at all, but a species of large saltwater
clam. Native to the
Pacific Northwest coast of the
United States and
Canada, the geoduck (
Panope generosa) is the largest burrowing clam in the world, weighing in at anywhere from 1-3 pounds at maturity. The appearance of geoduck's large, protruding siphon has led to the mistaken belief that the geoduck has properties of an
aphrodisiac.
