Which of the following rats is known for being the best swimmer?

The Norway rat is known for its exceptional swimming abilities. This species, also referred to as the brown rat or common rat, is recognized not only for its adaptability to various environments but also for its proficiency in swimming. Norway rats can traverse through water and are even capable of swimming considerable distances, which helps them escape predators and search for food sources in urban and rural settings. Their strong bodies and large size provide them with the strength needed for swimming, making them the best swimmers among the listed options.

In contrast, the roof rat and black rat, while they can swim, are not as adept as the Norway rat. The house mouse, although it can swim as well, lacks the robust physical structure that allows Norway rats to excel in aquatic conditions. Understanding the swimming capabilities of these rodents is essential in pest control and management, as their swimming skills can affect how they invade structures or interact with their environment.
