Study Notes
Clam Anatomy and Classification
-
Umbo: The raised, hinge-like area on the shell of the clam, serving as a landmark for the growth direction.
-
Anterior Adductor Muscle: Muscle located at the front of the clam, responsible for closing the shell and providing strength during contraction.
-
Posterior Adductor Muscle: Muscle positioned at the back of the clam, functioning similarly to the anterior muscle by allowing shell closure.
-
Mantle: A significant, protective tissue layer that covers the internal organs and secretes the shell in bivalves.
-
Gills: Specialized organs utilized for respiration and filter feeding, located within the mantle cavity.
-
Foot: A muscular structure that allows clams to burrow into the substrate or move along the seafloor.
-
Heart: The central organ of the circulatory system, responsible for pumping blood throughout the clam's body.
-
Phylum Mollusca: Classification group that includes diverse creatures like clams, oysters, and mussels, characterized by soft bodies and often a hard shell.
-
Bivalvia: The class within the phylum Mollusca containing clams, oysters, mussels, and similar organisms, distinguished by their two-part shell and filter-feeding mechanism.
