brown rat
Norway's namesake pest
The brown rat is the common rat found worldwide, also called the Norway rat despite originating in Asia.
It's the dominant rat species in temperate regions, thriving near human settlements.
Brown rats are larger than black rats, with coarse brownish-gray fur, small ears, and a tail shorter than the body.
They're the standard laboratory rat.
