The upper figure is a vertical projection divided into bilaterally symmetric 30 degree sectors, with 0 degrees upstream and 180 degrees downstream. The dots indicate sites of prey capture, the cross indicates the centroid of the projected area in the top view, and the arrow indicates the direction of flow. The lower figure is a lateral projection showing the dimensionless five sector height coordinate used

The lower figure is a lateral projection showing the dimensionless five sector height coordinate used. at lower speeds were measured directly through a dissecting microscope with mi- crometer ocular suspended above the flow tank. At the higher flow speeds tested, deflections were measured on tracings made from films of colonies in flow. Films were made using a Minolta XL 401 Super 8 mm movie camera with macro lens and were single-frame projected onto tracing paper. Deflections were measured to the nearest mm with either scheme. In both types of experiments, polyps were carefully chosen to be those deflecting in a plane parallel to the focal plane of the Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Marine Biological Laboratory (Woods Hole, Mass. ); Marine Biological Laboratory (Woods Hole, Mass. ).
