Characteristics

The members of this family are found in muddy sand or gravel at or below low tide mark. They have characteristically rounded shells with forward-facing umbones (projections). The valves are flattened and deeply etched with concentric rings. Each valve bears two cardinal and two plate-like lateral teeth. These molluscs do not have siphons but the extremely long foot makes a channel which is then lined with slime and serves for the intake and expulsion of water.[1]
