Overview of the Clam
The clam we dissected was a bivalve mollusk clam. The two major parts that need to be cut to open the clam is the anterior and posterior abductor. Once they are cut we are then able to open the clams shell.
External Anatomy of the Clam
- Umbo- the white bump on the shell of the clam. It serve as a shield for the clam. It is also known as the oldest part of the clam
- Hinge Ligament- It is a ligament that hold the two side of the shell together. The ligament can also be function as a spring to automatically open the shell of the clam.
- Posterior side- The side of the clam that is right of the umbo.
- Anterior side- The side of the clam that is left of the umbo.
- Dorsal side- The side that have the umbo.
- Ventral- The backside of the clam.
- Valve- It what keep the two side of the clam close.
Internal Anatomy of the Clam
- Gonad- produce the gametes for the hapliod gamete reproductive system
- Anterior abductor muscle- holds the left side of the clam down
- Posterior abductor muscle- holds the right side of the clam down
- Gill- take oxygen from the water and strain the water for food
- Labiel palps- control the amount of food digested, sorts food
- Siphon- intakes and expells water
- Mantle- allows the clam to sense the world around it, allows the water to flow around and through the filter-feeding organs, the gills
- Foot- digs into the sand, movement
