Here's a single frame from a short video of an unusually cooperative hypotrich, showing what I take to be the undulating membrane and three anterior cirri.

The video, slowed down to 7.5 frames per second (1/8 speed) can be found here (2.6MB, DivX format avi).
I question whether 60 frames per second is actually fast enough to resolve the motion of these cilia. I find it very odd that the wave seems to be moving clockwise, while debris in the water is obviously being swept rapidly down the left side -- counter-clockwise. I suspect temporal aliasing (strobing), like the old wagon-wheel-runs-backward effect. Does anybody here know the actual motion and period of oscillation for the cilia?
