Flows and forces in the collective motion of the nematode Turbatrix Aceti*

We experimentally study the collective motion of the nematode Turbatrix Aceti. We have previously shown that these nematodes, which self-propel and undulate their bodies, constitute a new kind of active matter where synchronization of the motion and the synchronization of oscillations happen at the same time. We have discovered that under favorable conditions they will produce a collectively beating and moving metachronal wave, which is capable of driving fluid flows. In this presentation, we will discuss both these flows and the forces that they generate.
