what is geoduck

The shell of the clam ranges from 15 centimetres (5.9 in) to over 20 centimetres (7.9 in) in length, but the extremely long siphons make the clam itself much longer than this: the neck or siphons alone can be 1 metre (3.3 ft) in length.he geoduck is the largest burrowing clam in the world, and one of the longest-lived animals of any type.
