It is hard to guess what a Bare-tailed woolly opossum weights. But we have the answer:
An adult Bare-tailed woolly opossum (Caluromys philander) on average weights 246 grams (0.54 lbs).
The Bare-tailed woolly opossum is from the family Didelphidae (genus: Caluromys). They can live for up to 6.33 years. When reaching adult age, they grow up to 22.4 cm (0′ 9″). On average, Bare-tailed woolly opossums can have babies 2 times per year with a litter size of 4.
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 bare-tailed woolly opossum (Caluromys philander) is an opossum from South America. It was first described by Swedish zoologist Carl Linnaeus in 1758. The bare-tailed woolly opossum is characterized by a gray head, brown to gray coat, orange to gray underside and a partially naked tail. It is nocturnal (active mainly at night) and solitary; there is hardly any social interaction except between mother and juveniles and in mating pairs. The opossum constructs nests in tree cavities, and its litter size ranges from one to seven. Gestation lasts 25 days, and the juveniles exit the pouch after three months; weaning occurs a month later. The bare-tailed woolly opossum inhabits subtropical forests, rainforests, secondary forests, and plantations; its range extends from northern Venezuela to northeastern and southcentral Brazil. The IUCN classifies this opossum as least concern.
