Clams

Clams are bivalve mollusks that inhabit marine environments worldwide, ranging from shallow coastal waters to deep ocean floors. They are characterized by their two hinged shells, which they can close tightly for protection. Clams come in various sizes, from small species found in intertidal zones to larger varieties like giant clams found in tropical coral reefs. These mollusks play important ecological roles, filtering water to feed on plankton and detritus, thereby improving water quality. Some clams form symbiotic relationships with algae, benefiting from photosynthesis while providing a substrate for their partners.
