The New Guinean rat is a species of rodent found on the island of New Guinea. There are several synonyms for this particular rat, including Rattus novaeguineae, the New Guinea brown rat, and the Granitic rat. It has also been referred to as the Flores rat since it was first discovered on the island of Flores in Indonesia. This nocturnal rodent is generally found in forest habitats and feeds on a variety of plant material. Like many rodents, the New Guinean rat has the ability to reproduce quickly, making it a potential pest in some areas. Despite its less-than-glamorous reputation, this rat plays an important role in the ecosystem.
