Advanced Usage

• Taxonomic Hierarchy: The term is used to specify a level in biological classification: Kingdom > Phylum > Class > Order > Family > Genus > Species. For example: "The species belongs to genus Clethrionomys, family Cricetidae."
• Type Species: The type species for this genus is , the bank vole.

Variants and Related Words

Notes on Meaning

• The primary and only meaning of "genus " is taxonomic. It does not have idiomatic, colloquial, or alternative definitions outside of scientific classification.
• It refers specifically to a group of species sharing a common ancestor, not to an individual animal. An individual is a member of a species within the genus (e.g., , the northern red-backed vole).
