Definition

Noun: * A taxonomic genus of ciliated protozoans characterized by a goblet-shaped cell body attached to a substrate by a contractile stalk.

Usage

• The term "genus Vorticella" is used in scientific contexts, specifically in biology and microbiology, to classify and refer to this specific group of single-celled organisms.
• It is a formal, taxonomic name and is always capitalized.

Examples

• Under the microscope, we observed several organisms belonging to genus Vorticella.
• The distinguishing feature of genus Vorticella is its retractile stalk.
• A common species within genus Vorticella is .

Advanced Usage

• In taxonomic hierarchy, "genus Vorticella" is a rank below the family Vorticellidae and above the level of individual species.
• The name can be used in its abbreviated form after first use, e.g., "Specimens of were collected."

Variants and Related Words

• Vorticella (n): The common name for organisms within this genus, often used interchangeably in less formal scientific writing. Example: "A vorticella attached to the algae."
• Vorticellid (n/adj): (Noun) A member of the family Vorticellidae. (Adjective) Relating to or characteristic of this family. Example: "Vorticellid ciliates."

Synonyms

• Peritrich ciliate: This is a broader descriptive term for the subclass of ciliates to which belongs, referring to the ring of cilia around the oral opening. It is not a direct synonym but a categorical descriptor.

Notes on Meaning

• The definition refers specifically to the taxonomic grouping, not just the physical characteristics. While "goblet-shaped body with a retractile stalk" describes the morphology, "genus Vorticella" formally denotes the entire group of species sharing this and other genetic/evolutionary traits.
