Flows and forces in the collective motion of the nematode Turbatrix Aceti
ORAL
Abstract
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.
