It is hard to guess what a Sumichrast’s vesper rat weights. But we have the answer:
An adult Sumichrast’s vesper rat (Nyctomys sumichrasti) on average weights 59 grams (0.13 lbs).
The Sumichrast’s vesper rat is from the family Muridae (genus: Nyctomys). It is usually born with about 4 grams (0.01 lbs). They can live for up to 5.17 years. When reaching adult age, they grow up to 9.3 cm (0′ 4″). On average, Sumichrast’s vesper rats can have babies 8 times per year with a litter size of 2.
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.
Sumichrast’s vesper rat (Nyctomys sumichrasti) is a rodent of the family Cricetidae found from southern Mexico to Panama. It is named for the collector of the first specimen, and its closest relative is probably Hatt’s vesper rat, a similar, but slightly smaller, species from the Yucatán Peninsula.
