The geoduck clam inhabits the waters from Alaska to the Gulf of California in the northeastern Pacific, from the inter-tidal zone to depths of 350 feet. They are the largest of the burrowing clams, commonly reaching weights of more than three pounds, with some weighing more than ten pounds. Geoducks are also among the longest lived animals in the ocean, some living 140 years or more. They bury themselves up to three feet deep in mud, silt and gravel bottoms, hence their name from the Native American words which mean dig deep. Geoducks are commercially harvested with high-pressure jet hoses from both wild and cultivated beds, primarily in the northern end of their range where they are most common. They are now managed within sustainable guidelines in both U.S. and Canadian waters. Geoducks are prey for large sea stars, crabs, fish, and birds.
