Difference Between Clam and Mussel Understanding the Key Differences Between These ShellfishClams and mussels are both popular types of shellfish commonly used in various cuisines around the world. While they may look similar to the untrained eye, there are many differences between clams and mussels, including their appearance, habitat, taste, texture, and how they are cooked. Knowing the distinction between these two mollusks can help you choose the right one for your recipes and appreciate their unique qualities.
What Are Clams?
Clams are bivalve mollusks that live buried in sand or mud in both saltwater and freshwater environments. Their shells are typically oval or round and come in lighter shades, often beige or grayish white. Clams are known for their slightly sweet and salty flavor, and they can be enjoyed raw, steamed, fried, or baked.
Key Characteristics of Clams
-
Hard, rounded shells
-
Pale color with visible ridges
-
Burrow into sand or mud
-
Found in oceans, rivers, and lakes
-
Firm, chewy meat with a briny flavor
Clams are a common ingredient in chowders, pasta dishes, and appetizers. Their firm texture makes them suitable for hearty meals.
What Are Mussels?
Mussels are also bivalve mollusks, but they are mostly found in saltwater, often attached to rocks, piers, or ropes. Mussels have dark blue or black shells that are long and narrow. They are known for their mild, slightly sweet flavor and soft texture, making them ideal for light and flavorful dishes.
Key Characteristics of Mussels
-
Long, dark, and smooth shells
-
Usually found in saltwater environments
-
Attach themselves to hard surfaces with threads
-
More tender texture
-
Mild and slightly earthy taste
Mussels are popular in Mediterranean and European cooking, often steamed with wine, garlic, or herbs.
Appearance How to Tell Them Apart
Visually, clams and mussels are easy to distinguish once you know what to look for.
-
Clams Rounded, thicker shells that are usually light-colored with ridges.
-
Mussels Narrower, longer shells that are darker in color, typically blue-black or brown.
Clams tend to have a more rugged, solid look, while mussels appear sleeker and smoother.
Habitat and Living Environment
Another major difference lies in where these shellfish live.
Clams
-
Live buried under sand or mud
-
Found in both freshwater and saltwater
-
Do not attach to surfaces
Mussels
-

-
Attach to rocks, docks, and ropes using byssal threads

This difference affects how they are harvested. Clams are dug out of the ground, while mussels are usually harvested from ropes or rocky surfaces.
Taste and Texture
When it comes to flavor and mouthfeel, clams and mussels offer distinct experiences.
Clams

Sustainability and Environmental Impact
Mussels are often praised for being one of the most sustainable seafood choices available. They require no feed, filter the water naturally, and are farmed using low-impact methods.
Clams can also be farmed sustainably, though wild harvesting methods may sometimes disturb natural ecosystems. Choosing responsibly sourced shellfish supports both marine life and long-term food supplies.
How to Buy and Store
When buying clams or mussels, freshness is key. Look for shellfish that are alive, as indicated by tightly closed shells or those that close when tapped.
Buying Tips

Rinse both clams and mussels before cooking, and remove any sand or debris.
Cooking Tips and Safety
Shellfish are easy to prepare with a few basic guidelines.
For Clams
-
Soak in cold salted water for 20-30 minutes to purge sand
-
Steam or boil until shells open (discard any that stay closed)
