The black‑coated variant of the common house mouse is called the black house mouse (Mus musculus).

What is the name of a black mouse? - in detail

A black mouse is commonly referred to as a “black laboratory mouse” when describing the standard scientific strain used in research. The most frequent laboratory strain bearing a dark coat is C57BL/6, abbreviated as “B6.” This strain exhibits a uniform black fur coloration and is the reference genotype for many genetic studies.

Other contexts use different terminology:

  • Pet trade: The term “black mouse” or “black dwarf mouse” describes domesticated varieties selected for their dark pigmentation.
  • Wild species: The house mouse (Mus musculus) includes melanistic individuals that are simply identified as black mice within field reports.
  • Literature and media: Characters such as “Blackie” or “Midnight” serve as proper names for fictional black rodents.

Key characteristics of the laboratory B6 strain include:

  1. Genome fully sequenced, providing a baseline for comparative genetics.
  2. High reproductive rate, facilitating large colony maintenance.
  3. Susceptibility to diet‑induced obesity, making it a model for metabolic research.
  4. Dark coat results from a recessive allele at the agouti locus (a/a).

When selecting a black mouse for experimental work, researchers consider genotype, health status, and breeding history. Documentation of the strain’s origin, such as “C57BL/6J” from The Jackson Laboratory, ensures reproducibility across studies.
