How are rats named? - briefly
Scientific classification assigns each rat a Latin binomial—genus Rattus followed by a species epithet (e.g., Rattus norvegicus), reflecting taxonomic relationships. Domestic owners typically select short, distinctive names based on appearance, behavior, or personal preference.
How are rats named? - in detail
Rats receive names through a combination of scientific classification, laboratory conventions, and pet‑owner preferences.
In taxonomy, each species is identified by a Latin binomial, for example Rattus norvegicus for the Norway rat and Rattus rattus for the black rat. These names follow the International Code of Zoological Nomenclature, which requires a genus name (capitalized) and a specific epithet (lowercase), both italicized. The authority who first described the species and the year of publication are often appended (e.g., Rattus norvegicus Berkenhout, 1769).
Laboratory rodents are labeled according to institutional protocols. Common elements include:
- Strain designation – indicates genetic background (e.g., Sprague‑Dawley, Wistar).
- Colony identifier – a short alphanumeric code unique to the breeding colony.
- Individual number – a sequential or barcode tag assigned at birth.
- Sex and age markers – sometimes appended to distinguish experimental groups (e.g., SD‑C01‑M‑10 wks).
Pet owners typically choose names based on personality, appearance, or cultural references. Unlike scientific naming, these names are informal and may be recorded on microchips, tags, or veterinary records.
When a rat is transferred between facilities or owners, both the formal scientific designation and any existing informal name are documented to preserve traceability. This dual‑naming system ensures accurate communication in research, veterinary care, and pet management.
