What is the scientific name of the Norway rat?

The scientific name of the Norway rat is Rattus norvegicus. This species is well-known for its adaptability to various environments and its prevalence in urban areas. Understanding the correct scientific classification is crucial because it helps in identifying the species accurately, which in turn is fundamental for effective pest control strategies.

Each scientific name is composed of a genus and species, and in this case, "Rattus" is the genus name which categorizes it within a specific group of rodents, while "norvegicus" identifies the particular species. This distinction is important as Norway rats exhibit different behaviors and control measures compared to other related rodents, such as the black rat, Rattus rattus, or house mouse, Mus musculus.

The other names listed belong to different species altogether. Mus musculus refers to the house mouse, Rattus rattus refers to the black rat, and Cavia porcellus is the scientific name for domestic guinea pigs, showing the diversity within rodent classifications. Understanding these distinctions not only helps in accurate identification but also enhances pest management practices specific to each rodent species.
