That is: preferred particles are transport ed inside the marginal groove proper, whereas particles destined for rejection are carried superficially in a string of mucus. Sorting also occurs at the ventral margin of the outer demibranch; desirable particles are retained on the outer demibranch, whereas unacceptable particles are transferred to the inner demibranch and ultimately excluded from ingestion.
And when the pallial cavity was entered through the pedal gape, the foot usually touched the OIT, coating it with mucus. Results were based on the examination of 21 mussels.
At high concentrations ([great than][10.sup.6] [ml.sup.-1]), particles are sometimes carried along the ventral margin in clumps of mucus. As a result of these three particle trajectories, desirable particles are retained on the Outer demibranch, while unacceptable particles are transferred to the inner demibranch and ultimately excluded from ingestion.
Particles transported in the superficial groove are embedded in a string of mucus, up to 80 [micro]m thick (Figs.
Particles transported anteriorly inside the marginal groove proper are also embedded in a string of mucus (Figs.
Once the ball of mucus and particles reaches a particular size, the palps push or "clap" the ball away.
When mussels were fed high concentrations of a combination of both desirable and unacceptable particles (Microcystis and Scenedesmus), the ball of mucus that forms near the palp apices was drawn back between the palp lamellae and once again dispersed.
