Which statement is true regarding the tail of a roof rat?

The tail of a roof rat is recognized for being longer than its head and body. This characteristic is significant for several reasons. Firstly, a long tail aids in balance and climbing, which are critical for these agile creatures that often inhabit trees and structures in urban environments. It also plays a role in their communication, as they can use their tails to express emotions and intentions toward other rats.

In contrast, other options suggest proportions that do not accurately reflect the physical characteristics of roof rats. For example, saying the tail is shorter or as long as the body underestimates the tail's length and its important functions. Describing the tail as stubby and thick also inaccurately depicts the slender, elongated form that is typical of a roof rat's tail. Understanding these aspects helps in recognizing roof rats in the field and can inform appropriate pest control strategies.
