The 'Giant White-tailed Rat' (''Uromys caudimaculatus'') is an Australian rodent native to tropical rainforest of north Queensland ^[1], with subspecies occurring in New Guinea and the Aru Islands.^[2] It is one of the largest rodents in Australia, reaching up to 1 kg in weight ^[3], is grey-brown above, cream to white below, and has a long, naked tail of which the distal section is white (Moore 1995).
Breeding commences in September or October, peaking in December and January at the height of the wet season. After a gestation of 36 days, a litter of two to three (rarely four) young are born, and remain with the mother for approximately three months (Moore 1995).
