It is hard to guess what a Lutrine opossum weights. But we have the answer:
An adult Lutrine opossum (Lutreolina crassicaudata) on average weights 556 grams (1.23 lbs).
The Lutrine opossum is from the family Didelphidae (genus: Lutreolina). They can live for up to 3 years. When reaching adult age, they grow up to 32.4 cm (1′ 1″). On average, Lutrine opossums can have babies 2 times per year with a litter size of 7.
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 lutrine opossum (Lutreolina crassicaudata), also known as the little water opossum, thick-tailed opossum, or coligrueso is an opossum species from South America and is monotypic in the genus Lutreolina.
