Incurrent and excurrent siphons are the tubular structures that burrowing bivalve molluscs, such as clams, use to feed, respire, reproduce and expel waste into the water, while the body of the bivalve remains buried beneath the surface of the sediment, where it is hidden from predators.
The bivalve's two siphons are situated at the posterior edge of the mantle cavity. There is an inhalant or incurrent siphon, and an exhalant or excurrent siphon. The water is circulated by the action of the gills. Usually water enters the mantle cavity through the inhalant siphon, moves over the gills, and leaves through the exhalant siphon.
The modified female mantle extended from a point immediately anterior to the incurrent siphon to a point directly ventral and opposite to the posterior-most end of the hinge ligament [ILLUSTRATION FOR FIGURE 2 OMITTED].
