The geoduck is known as the largest burrowing clam and has a siphon that can extend up to 4 feet despite its shell being only 7 to 9 inches long. Native to the Pacific coast of North America, its name originates from the language of the Nisqually people and means dig deep. This unusual creature can live for over 160 years and is a sought-after delicacy in many Asian cuisines. Its long lifespan and slow growth make sustainable harvesting essential to protect this remarkable animal. | The History
