geoduck
A type of saltwater clam native to the west coast of North America.
The shell of the clam ranges from 15 centimeters (5.9 in) to over 20 centimeters (7.9 in) in length, but the extremely long siphons make the clam itself much longer than this, with the siphons alone being able to reach 1 meter (3.3 ft) in length. The geoduck is one of the largest clams in the world and one of the longest-lived animals in the world, with the oldest known specimen having lived 168 years.
Rather infamous for its phallic shape, which led into it became a delicacy and are believed to have aphodisaic properties.
