Clam (Bivalvia or Pelecypoda)
Background
Tend to inhabit shallow waters, there is over 15,000 different living species and 500 live in fresh water while the rest live in salt water. Clams are filter feeders, they pump water through their bodies to capture microscopic organisms such as plankton. The clam breaths through gills, the gills are used for both breathing and feeding the clam. The clam sticks the ends of its siphons out of the shell and food and oxygen come in one end and out the other. Clams move by the use of their foot, the foot allows the clam to move from side to side when necessary. Below is a video of a clam using its foot in order to move on land:
External Anatomy
Umbo— oldest part of the clam, where the clam, highest part of the shell
Growth Lines— shows the age of the clam
Hinge Ligament— hinges the valves together and allows them to open and close, important part
Internal Anatomy
Stomach— separates water from the food, starts digestive process
Gill— filters oxygen from the water in order for the clam to breathe
Mantle— cover for the clam that helps with growth, respiration, and shell color
Axe foot— allows the clam to burrow and move around, axe shaped
