: By filtering vast amounts of water, bivalves like mussels and oysters act as natural water purifiers in ecosystems.

: Most bivalves are filter feeders. They draw water into their mantle cavity through a siphon, where specialized gills trap organic particles. Internal Systems

: They breathe through plate-like gills (ctenidia) located in the mantle cavity.
