The geoduck is a species of very large saltwater clam.
It is the largest burrowing clam in the world, weighing in at an average of one to three pounds (0.5–1.5 kg) at maturity, but specimens weighing over 15 pounds (7.5 kg) and as much as 2 meters (over 6.5 ft) in length are not unheard of. (The actual shell is about 15 centimetres (5.9 in) to over 20 centimetres (7.9 in) in length)
Geoducks are one of the longest-living organisms in the Animal Kingdom. They have a life expectancy of about 146 years, with the oldest recorded at over 160 years. Scientists speculate that the geoduck's longevity is the result of low wear and tear.
