* Examples include:

* Hard-shelled clam

* Soft-shelled clam

* Quahog

Freshwater Clams

* Live in lakes, rivers, and other freshwater bodies

* Have a lower tolerance for salinity

* Can filter less salt from the water

* Typically have a shorter lifespan than saltwater clams

* Examples include:

* Fingernail clam

* Pea clam

* Asiatic clam

* Rainbow mussel
