It is hard to guess what a Giant white-tailed rat weights. But we have the answer:
An adult Giant white-tailed rat (Uromys caudimaculatus) on average weights 644 grams (1.42 lbs).
The Giant white-tailed rat is from the family Muridae (genus: Uromys). It is usually born with about 20 grams (0.04 lbs). When reaching adult age, they grow up to 28.3 cm (1′ 0″). Usually, Giant white-tailed rats have 2 babies per litter.
As a reference: An average human weights in at 62 kg (137 lbs) and reaches an average size of 1.65m (5′ 5″). Humans spend 280 days (40 weeks) in the womb of their mother and reach around 75 years of age.
The giant white-tailed rat (Uromys caudimaculatus) is an Australian rodent native to tropical rainforest of north Queensland, with subspecies occurring in New Guinea and the Aru Islands. It is one of the largest rodents in Australia, reaching up to 1 kg in weight, 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).
