It is correctly referred to as a sphinx rat, commonly called a hairless rat.
What should you call a sphinx rat? - in detail
When identifying a hairless laboratory mouse that exhibits the distinctive cranial structure of a sphinx, the most precise designation combines breed and morphological descriptors. The term “hairless sphinx mouse” accurately conveys both the lack of fur and the characteristic skull shape. If the animal belongs to a specific genetic line, prepend the line’s name, for example, “C57BL/6 hairless sphinx mouse,” to indicate strain background.
In scientific literature, the following conventions are widely accepted:
- Genus and species: Mus musculus – the standard taxonomic label for the common house mouse.
- Strain identifier: a alphanumeric code such as C57BL/6, BALB/c, or a custom designation.
- Phenotypic modifier: “hairless” or “nude” to denote the absence of pelage.
- Morphological qualifier: “sphinx” to specify the skull morphology.
Combining these elements yields a complete name, for instance: Mus musculus C57BL/6 hairless sphinx. This format aligns with the International Committee on Standardized Genetic Nomenclature for laboratory animals and ensures unambiguous communication across research groups.
When informal naming is required, such as in a pet setting, the concise label “sphinx rat” is acceptable, provided that the audience understands the animal is a mouse, not a true rat. To avoid taxonomic confusion, add a clarifying phrase: “hairless sphinx mouse (often called a sphinx rat).”
If the animal is part of a breeding program, register the line with a unique identifier, for example, “SR‑01,” and reference it alongside the scientific name: Mus musculus SR‑01 hairless sphinx. This practice facilitates pedigree tracking and genetic quality control.
In summary, the recommended nomenclature hierarchy is:
- Taxonomic base – Mus musculus
- Strain or line code – C57BL/6, SR‑01, etc.
- Phenotypic modifier – hairless (or nude)
- Morphological qualifier – sphinx
Applying this structure yields a clear, detailed, and universally understood name for the animal in both formal research contexts and informal discussions.
