Geoducks reproduce sexually by spawning. Spawning is the process of aquatic animals releasing the eggs and sperm into the water in order to reproduce. The geoducks usually spawn from the late winter to early summer months. The greatest amount of activity occurs during the months of May and June. During this time the male spawns millions of sperm into the water. The females then spawn their eggs and that can be as many as five million at a time.<ref name=mlife> [http://wikis.evergreen.edu/marinelife1011/index.php/Panopea_generosa#cite_note-2 Ever-green] ''marine-life-1011''.

The geoduck clam can be found along the West Coast of [[North America]], in locations ranging from [[Baja, California]] all the way to [[Alaska]]. It lives in lower intertidal and subtidal zones of [[bays]], [[sloughs]], and [[estuaries]]. Geoducks bury themselves below the sand and extend their [[siphon]] out to filter feed. They will burrow in any [[substrate]], from soft mud to pea gravel. The geoduck is a [[filter feeder]]. This means it will eat any small organisms that it filters through its siphon. The major food source of ''Panopea generosa'' is [[phytoplankton]]. The predators of the geoduck includes: [[humans]], [[crabs]], [[sea stars]], [[sea otters]], and [[snails]]. Even with all of these threats some geoducks can live to be over a hundred years old.<ref> [http://wikis.evergreen.edu/marinelife1011/index.php/Panopea_generosa#cite_note-2 Ever-green] ''marine-life-1011''.
