Light micrograph of a group of Vorticella,a sessile,ciliate protozoan of the order Peritricha. Each single-celled individual has a head or zooid and a retractable stalk which anchors it to the substrate. The flattened top of the head bears the mouth and a complicated wreath of hair-like cilia. The beating of the cilia creates tiny vortices in the water which wash bacteria into the organism's mouth. Many tiny bacteria are visible suspended in the water. Magnification: x70 at 35mm size | |
