Geoduck are the largest burrowing clam, have an elongated shell and can grow to a shell length of 7″ with a siphon up to 3 feet long.  They have a long siphon which extends well beyond the shell and it’s appearance is often associated with an elephant trunk or with certain male anatomy.  The average market weight of live Geoduck is about 2 pounds.  They can live to be 100 years old, but typical harvest age is 8-9 years.  The siphon is the edible portion.  It is covered by a tough skin which can be easily removed by soaking for a few minutes in warm water.  Geoduck spawn in the winter.  Their spawning material does not affect the quality of the meat except that shelf life will be shorter.
