Vorticella (Ciliata)
These bell-shaped ciliates live in fresh or salt water attached by a slender, unciliated stalk to aquatic plants, surface scum, submerged objects, or aquatic animals. Vorticella eat bacteria and small protozoans, using their cilia to sweep prey into their mouth-like openings.

A total of 51 taxa belonging to 11 families and 20 genera were identified. Helicostomella subulata, Codonellopsis schabi, Stenosemella nivalis and Salpingella decurtata were the dominant ... affected by temperature, which was the most important environmental factor determining their seasonality.

Your Microsopic Friends, The ciliates
via UCMP - Berkeley
The Ciliata, or Ciliophora, includes about 7000 known species of some of the most complex single-celled organisms ever. They derive their name from the Latin word for “eyelash,” which describes the appearance of many ciliates quite well: some or all of the surface of a ciliate is covered with relatively short, dense hairlike structures, the cilia, which beat to propel the ciliate through the water and/or to draw in food particles.
ciliates include some of the largest free-living protists; a few genera may reach two millimeters in length. They are abundant in almost every environment with liquid water: ocean waters, marine sediments, lakes, ponds, and rivers, and even soils. Because individual ciliate species vary greatly in their tolerance of pollution, the ciliates found in a body of water can be used to gauge the degree of pollution quickly.
Most ciliates are free-living forms. Relatively few are parasitic. Free-living ciliates may feed on bacteria, algae, or even other ciliates; Didinium, shown above, is a rapacious hunter and consumer of other ciliates. Some ciliates harbor symbiotic bacteria or algae. Free-living ciliates may be found almost anywhere there is liquid water, but different forms predominate in different habitats. ciliates in soils tend to be small forms that can form resistant cysts in order to survive long periods of drying. Tintinnids abound in the marine plankton, where they and other ciliates may consume up to 90% of the production of planktonic bacteria and algae. Large ciliates are common in freshwater environments, in particular those that have been organically enriched (such as by sewage). By listing and counting the ciliate species in a sample of water, it is possible to estimate quickly how much organic material — which could include pollution — is present…
