Mussel Facts

Mussels have been a food source for humans for thousands of years and today remain a popular seafood dish. They can be found in both freshwater and saltwater, but generally only saltwater mussels are used for food. Mussels are high in protein and low in fat and sodium, so they are often considered a healthy seafood option.

  1. A Bivalve

    • Mussels consist of two hinged shells, or valves. The shells are connected by a ligament, and mussels on the inside are responsible for opening and closing the shells.

    Attachment

    • Mussels attach themselves to rocks and other structures on ocean and lake floors with byssal threads. These strong threads, sometimes called beards, are emitted as a liquid that hardens in the water.

    How They Breathe

    • Mussels breathe by filtering water through siphons. This is also the process mussels use to eat. Their primary food source is plankton.

    Shore Dwellers

    • Saltwater mussels generally remain near the coastline and are often not even fully submerged in the ocean water. Many mussels live in the area affected by the ocean's tides.

    Cooking Mussels

    • Mussels have to be cleaned well before being cooked. They can be grilled, steamed, baked or fried, and many preparations call for the mussels being seasoned with butter and garlic. In some cultures they are popularly served with pasta.
