STRUCTURE OF FEEDING CURRENT Motion of Diaptomus minutus while feeding and the motion of suspended particles
.

.

.
Using special optical systems allowed us to observe free-swimming copepods feeding on suspended algae.  We made these observations with video at 30 frames per second.  Frame by frame analyses and image processing rendered two figures: an animated GIF file, and a graph of the paths of suspended particles as seen from the animal's point of view.  The comparison with results from Computational Fluid Dynamics is astonishing
.
In the drawing on the left the positions of the suspended particles with respect to the moving animal were determined frame by frame. Algae within the red zone will pass through the capture area and may be captured
