Vorticella sp. living in in clusters on the root of Duckweed (Lemna sp.) in west Wales, each stalk is individually attached to the root surface. - HD stock video

The stalk is made up of an external sheath that contains a fluid and a spirally arranged contractile fibril called a myoneme that contracts when stimulated. When disturbed, the vorticella contracts and the stalk thread is shortened, causing the sheath to coil tightly like a spring. The swimming microorganism at the end of the clip is a Vorticella daughter cell called a Telotroch. Vorticella are heterotrophic organsims. They prey on bacteria. Vorticella use their cilia to create a current of water (vortex) to direct food towards its mouth.Phase Contrast illumination, each inverted bell-shaped cell is approximately 50-100 microns in length.
