The size of a clam can vary depending on the species. They are filter feeders, playing an essential role in aquatic ecosystems by cleaning the water. Clams are a versatile ingredient in many dishes, from clam chowder to steamed clams, and are valued for their distinct, briny flavor. They have been a source of food for humans for thousands of years and continue to be a commercially important shellfish.
