Geoduck: The Ocean’s Bounty – Everything You Need to Know About the King Clam

The geoduck (pronounced "gooey-duck") is one of the most fascinating seafood delicacies in the world. Known as the largest burrowing clam, geoducks are found along the Pacific Northwest coast and are highly prized in Japanese, Chinese, and North American cuisine. With their sweet, crisp texture and unique appearance, geoducks are a true treasure from the ocean.

In this article, we’ll explore everything about geoduck—from its habitat and nutritional benefits to cooking techniques, recipes, and sustainability. If you're wondering where to buy fresh geoduck, we’ll also guide you to the best places to purchase high-quality geoduck online.

What is Geoduck?

Geoduck (Panopea generosa) is a saltwater clam native to the coastal waters of the Pacific Northwest, particularly in Washington, British Columbia, and Alaska. It has a distinct long siphon (neck) that can grow up to 3 feet long, making it the largest burrowing clam in the world.

Unlike other clams that remain fully enclosed within their shells, geoducks extend their siphon out of the shell to filter water and extract nutrients. This unique appearance makes them one of the most recognizable and intriguing shellfish in the culinary world.

Where is Geoduck Found?

Geoducks thrive in sandy seabeds and coastal waters at depths ranging from 10 to 80 feet. They burrow deep into the seabed, with only their siphons exposed above the surface.

They are harvested primarily in Washington State and British Columbia, where fisheries carefully manage populations to ensure sustainability. Some geoducks are also farmed through aquaculture, reducing pressure on wild populations.

How Long Do Geoducks Live?

One of the most fascinating facts about geoducks is their incredible lifespan. They can live up to 150 years, making them one of the longest-living marine creatures.

Their slow growth rate and long life cycle contribute to their rich, sweet flavor and firm texture, which make them a prized ingredient in seafood cuisine.
