 in the world, the geoduck may weigh up to 12 lb (5.4 kg). The shell is thin, lacks teeth, and may attain a length of 8 in. (20 cm). The valves, or two parts of the shell, are always open in the adult, because the body and siphons are too large to be retracted. Geoducks are found from British Columbia to S California, with the largest population in Puget Sound. They inhabit mud flats, burrowing to a depth of 3 or 4 ft (90–120 cm), where they live in semipermanent burrows. Although they are edible, they are not widely marketed due to their inaccessibility: They are exposed for only a few hours a month during minus tides, at which time they can be obtained with a shovel. Digging geoducks is considered a sport in Washington, where there is a limit of three per day. Geoducks are classified in the phylum MolluscaMollusca
, taxonomic name for the one of the largest phyla of invertebrate animals (Arthropoda is the largest) comprising more than 50,000 living mollusk species and about 35,000 fossil species dating back to the Cambrian period.

It is noteworthy that allowable fishing mortality rates <10% of the stock are more similar to the mortality rates of the longest-lived bivalves, such as geoducks and ocean quahogs (e.g., Bradbury and Tagart, 2000; NEFSC (2)), than other species with life spans of the same order as the oyster, emphasizing the fact that oysters in the Mid-Atlantic region are much more akin in their population dynamics to long-lived k-selected species than to short lived r-selected ones.
Trapped in poverty and given the incentives of the market, in 1999 members of the Skokomish Indian Tribe were caught secretly dumping nearly seventy thousand pounds of lower-grade geoduck clams so the shellfish would not count against their state-enforced quotas (Associated Press 2000).
