It is hard to guess what a Alston’s mouse opossum weights. But we have the answer:
An adult Alston’s mouse opossum (Micoureus alstoni) on average weights 132 grams (0.29 lbs).
The Alston’s mouse opossum is from the family Didelphidae (genus: Micoureus). When reaching adult age, they grow up to 19.2 cm (0′ 8″).
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.
Alston’s mouse opossum (Marmosa alstoni), also known as Alston’s opossum, is a medium-sized pouchless marsupial of the family Didelphidae. It is arboreal and nocturnal, inhabiting forests from Belize to northern Colombia. The main components of its diet are insects and fruits, but it may also eat small rodents, lizards, and bird eggs. It was formerly assigned to the genus Micoureus, which was made a subgenus of Marmosa in 2009.
