Nordic rats

Comparatively, the roof rat is smaller, but it adapts better to tropical regions and its color varies from black to grayish-white. Two distinctive characteristics are that the ventral or abdominal part is lighter than the rest of the body, and that the tail is longer than the body length. In addition, the rat has larger eyes and ears, and a pointed nose. Roof rats can cUmb and live in overhead areas, especially when they coexist with Nordic rats. The Nordic rat dominates the roof rat, especially when they compete for food and space.
