Uromys is a genus of large, primarily arboreal rodents belonging to the subfamily Murinae. They are commonly referred to as giant rats or New Guinea rats, and the genus comprises several species found in various regions across the Indo-Australian Archipelago, particularly in Australia and Papua New Guinea.
Members of the Uromys genus typically have stout bodies, long tails, and robust limbs, making them well-adapted climbers. They possess sharp claws that aid in scaling trees and agile movements in their arboreal habitats. These rodents are characterized by their relatively large size compared to other rat species, with some individuals growing up to 50 centimeters in length, including their tail.
Uromys rats are generally herbivorous animals, sustaining themselves on a varied diet of leaves, fruits, seeds, and occasionally nuts and insects. They exhibit a preference for forested areas, particularly rainforests or similar habitats, where they dwell primarily in trees and bushes.
These rodents play an important ecological role by dispersing seeds across their habitats. As such, they contribute to the regeneration and maintenance of forests. In terms of reproduction, Uromys species have relatively long gestation periods, with the females giving birth to small litters after about five to six weeks of pregnancy.
Due to their large size and distinct adaptations, Uromys species have drawn considerable interest from researchers, conservationists, and wildlife enthusiasts seeking to learn more about their behavior, ecology, and conservation status.
