Is Vorticella a size?
A sessile Vorticella consists of the zooid (inverted-bell-shaped cell body; usually about 30–40 μm in diameter when contracted) and the stalk (3–4 μm in diameter and about 100 μm in length) (Figure 1A).
Is Vorticella a parasite?
The parasite was identified as Vorticella, a genus of peritrich protozoan. It is one of the very first protists seen by Antony van Leeuwenhoek who observed it through the lens of his simple microscope in the late seventeenth century.
What does a Vorticella do?
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.
Who first described Vorticella?
Vorticella was first described by Antonie van Leeuwenhoek in a letter dated October 9, 1676. Leeuwenhoek thought that Vorticella had two horns moving like horse ears near the oral part, which turned out to be oral cilia beating to create water flow.
What are Vorticella attached to?
Vorticellas eat bacteria and small protozoans and live in fresh or salt water attached to aquatic plants, surface scum, submerged objects, or aquatic animals. Although vorticellas are often found in clusters, each stalk is fastened independently.
Is a Vorticella unicellular or multicellular?
Vorticella is a unicellular ciliated aquatic protist. Newly budded cells are free swimming, but in older organisms, the long stalk is usually attached to some sort of substrate such a plant detritus, rocks, or even animals such as crustaceans.
What causes Vorticella?
The organism is named Vorticella due to the beating cilia creating whirlpools, or vortices. It is also known as the “Bell Animalcule” due to its bell-shaped body.
Is Vorticella a plant like protist?
Vorticella is a protozoa (protist) that belongs to the phylum Ciliophora. As such, they are eukaryotic ciliates that can be found in such habitats as fresh and salty water bodies among others. According to studies, Vorticella is the largest genus of sessile peritrich ciliates with over 100 identified species.
What is the class of Vorticella?

What is Vorticella?
Overview: What is Vorticella? Vorticella is a protozoa (protist) that belongs to the Phylum Ciliophora. As such, they are eukaryotic ciliates that can be found in such habitats as fresh and salty water bodies among others.
Is a Vorticella a feeder or suspension feeder?
Vorticella is a suspension feeder, and may have reduced or no cytopharynxes, a nonciliated tube for ingestion. There are oral cilia specialized for making water currents, cytostomes in a depression on the cell surface and structures for scraping and filtering food.
What is the peristomial disc of a Vorticella?
Vorticella has an anterior peristomial lip which is short and narrow. An outward-curving peristomial disc is associated with the peristome. The peristomial disc, which may have ringed ridges or undulations, encloses rows of cilia.
What is the difference between spasmoneme and Vorticella?
The spasmoneme is said to have higher specific power than the engine of the average car. Vorticella has an anterior peristomial lip which is short and narrow. An outward-curving peristomial disc is associated with the peristome.
