Ming was the oldest individual (non-clonal) animal ever discovered whose age could be precisely determined. [1] [2] [3] Thought to be 405 years old, Ming was later determined to be 507 years old, although the clam had previously been killed to make this determination. The size of the clam was 87 mm × 73 mm (3.4 in × 2.9 in).
The shell of the clam ranges from 15 centimetres (6 in) to over 20 centimetres (8 in) in length, but the extremely long siphons make the clam itself much longer than this: the "shaft" or siphons alone can be 1 metre (3 ft 3 in) in length. The geoduck is the largest burrowing clam in the world. [3]

The Palourde clam by far is the most common native clam and it is both commercially harvested as well as locally collected, and Spisula solida, a relative of the Atlantic surf clam on the other side of the Atlantic, is seeing increased interest as a food source and aquaculture candidate; it is mainly found in the British Isles in Europe.
