A mussel is a bivalve mollusc that can be found in lakes, rivers, creeks, intertidal areas, and throughout the ocean.
The saltwater mussels (family Mytilidae) and freshwater mussels (family Unionidae) are not thought to be closely related and are grouped in different subclasses, despite considerable similarities in appearance.
