Clam vs. Geoduck — What's the Difference?
By Tayyaba Rehman & Urooj Arif — Updated on May 6, 2024
Clams are bivalve mollusks with a variety of species and sizes, typically living buried in sand or mud, whereas geoducks are notably large, long-lived clams known for their protruding siphons and burrowing depth.

Key Differences
Clams are a diverse group of bivalves commonly found in both freshwater and saltwater environments, adapting to a wide range of habitats. Whereas geoducks (pronounced "gooey-duck") are a specific type of saltwater clam native to the Pacific Northwest, distinguished by their impressive size and long necks.
The typical clam has a relatively short lifespan, usually not exceeding 20 years. On the other hand, geoducks are among the longest-living animals of their kind, with lifespans that can exceed 140 years.
Clams can be small enough to fit in the palm of your hand, with many species averaging just a few inches in diameter. In contrast, geoducks are one of the largest clams, with their shell alone reaching up to 20 centimeters and their siphon extending much further.
In culinary contexts, clams are versatile, used in dishes from clam chowder to fried clam strips. Whereas geoducks are considered a delicacy, particularly prized in Asian cuisines for their unique texture and flavor.
Clams are generally easier to harvest and are collected from both wild and farmed sources. Geoducks, however, require deep digging to reach, as they burrow down several feet into the seabed, which makes them harder and more expensive to harvest.

How are geoducks harvested?
Harvesting geoducks involves digging deep into the sediment, often using water jets to expose the deeply buried clams.
Are clams and geoducks available year-round?
Clams are generally available year-round, though some seasons are better for harvesting than others. Geoducks, on the other hand, have more restricted harvesting times due to their deep burrowing habits and regulatory measures.
What are the main predators of clams?
Clams' predators include birds, sea stars, and humans, who harvest them for food.
What nutritional benefits do clams offer?
Clams are rich in protein, iron, and vitamin B12, making them a nutritious seafood choice.
How do clams reproduce?
Clams reproduce by releasing eggs and sperm into the water, where fertilization occurs externally.
How do geoducks reproduce?
Geoducks also reproduce by broadcasting eggs and sperm into the water column for external fertilization, similar to other clams.
Can clams move?
Clams can move by using their muscular foot to burrow through the sand or mud.
Can geoducks move?
Geoducks can slightly adjust their position but are generally not mobile due to their deep burrowing and long siphon.
What nutritional benefits do geoducks offer?
Geoducks are similarly nutritious, providing high protein, low fat, and good amounts of selenium and vitamin B12.
