- Northern quahogs (or hard clams) are the most commonly eaten species of clams in the U.S. and the ones most likely to be found in fish markets and grocery stores.
- Quahogs go by different names depending on their size (littlenecks, cherrystones, chowder clams).
- These clams come from wild fisheries and farms, and capturing methods and farming practices generally do little ecological damage.
