Clams are tiny ocean cleaners

Clams are unsung heroes of coastal ecosystems, constantly filtering water and keeping our oceans healthy. These bivalve mollusks draw in seawater, trapping microscopic algae, plankton, and pollutants on their gills before expelling cleaner water. A single medium-sized clam can filter several liters daily, with dense populations processing thousands of gallons. This natural filtration removes excess nutrients and sediments, preventing harmful algal blooms and improving water quality for fish and other marine life. Beyond cleaning, clams also create microhabitats, boosting biodiversity and strengthening coastal resilience against environmental changes.
