Pacific Geoduck (panapea generosa) – Zeballos, Vancouver Island
The pacific geoduck is the largest burrowing clam in the world and is only found on the west coast of North America. It burrows into the ocean floor where it remains for its entire lifespan which usually exceeds 100 years. Its age can be estimated by the growth rings on its shell. The oldest geoduck was discovered in British Columbia, and it was estimated to be 168 years old.
