What is a notable characteristic of the Norway rat's fur?

The notable characteristic of the Norway rat's fur is that it is coarse and typically exhibits a brownish or reddish gray color. This type of fur helps the Norway rat blend into its natural environment, which is often urban areas where it can find shelter and food. The coarse texture of their fur is adapted for the rat's active lifestyle, allowing it to navigate through various environments without much damage to its pelage.

In contrast, the other options provide descriptions that do not accurately reflect the characteristics of the Norway rat. Smooth and shiny fur might suggest another type of rodent, as many rats have a rough appearance. Long and fuzzy fur would align more with other species, such as pets or certain wild rodents, rather than the typically short and coarse fur of the Norway rat. Lastly, an entirely white fur coloration is not representative of the Norway rat, which is known for its brownish tones. This accurate identification of characteristics is essential not only for recognizing the species but also for understanding their behavior and habitat preferences.
