It is hard to guess what a Yellow-nosed cotton rat weights. But we have the answer:
An adult Yellow-nosed cotton rat (Sigmodon ochrognathus) on average weights 122 grams (0.27 lbs).
The Yellow-nosed cotton rat is from the family Muridae (genus: Sigmodon). It is usually born with about 5 grams (0.01 lbs). When reaching adult age, they grow up to 15.1 cm (0′ 6″). Usually, Yellow-nosed cotton rats have 3 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 yellow-nosed cotton rat (Sigmodon ochrognathus) is a species of rodent in the family Cricetidae. It is native to Mexico and to the states of Arizona, New Mexico, and Texas in the United States, where it inhabits mountain grassland, scrub, and pinyon-juniper woodland. It is common over much of its wide range and the IUCN considers it to be of “least concern”.
