 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.

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.
