They are located on the posterior side. The incurrent takes water in, the excurrent puts it out. do u know mrs sheetz??? this is an x-act question from her lab
The clam has two siphons excurrent and incurrent

the inhalent and the exhalent siphons
The clam has two siphons. The excurrent siphon (which expels water and waste out of the clam) and the incurrent siphon (which brings oxygen and food and water into the clam).
They have a hatchet-shaped foot that allow them to move, incurrent and excurrent siphons through which water passes and then they filter feed in that way, and powerful abductor muscles that draw the shell together to protect the clam's soft body.
Porifera, also known as sponges, are filter feeders that lack a true mouth or gut. They filter microscopic organisms and particles from the water to obtain nutrition through specialized cells in their bodies.
Generally the bivalves are filter feeders. As you look at a bivalve in the water and undisturbed one will see a slight protrusion of its siphons (incurrent and excurrent). Water enters the creature and passes over under and through the gills. These are covered with cilia which conduct the bits of detritus (microscopic organic debris in the water) to the "mouth" and into the digestive system where it will be hydrolyzed (digested) and absorbed and used as needed.
Siphons are specialized tubular structures that serve various functions in different organisms, primarily for the movement of fluids. Their function varies depending on the type of organism Read more... //tinyurl .com/55twnbnt
The siphon is part of the mantle of the mollusc, and the water flow is directed to (or from) the mantle cavity. A single siphon occurs in some gastropods. In those bivalves which have siphons, the siphons are paired.
siphons. Siphons are specialized structures that allow bivalves to intake and expel water for feeding, respiration, and reproduction.
Fist tell me what they are then ill tell you.
