How old does a Black-shouldered opossum get? (age expectancy)

What is the maximal age a Black-shouldered opossum reaches?

An adult Black-shouldered opossum (Caluromysiops irrupta) usually gets as old as 7.83 years.

When born, they weight 16 grams (0.04 lbs) and measure 1 cm (0′ 1″). As a member of the Didelphidae family (genus: Caluromysiops), their offspring is 2 babies per pregnancy. Fully grown, they reach a bodylength of 23.4 cm (0′ 10″).

As a reference: Usually, humans get as old as 100 years, with the average being around 75 years. After being carried in the belly of their mother for 280 days (40 weeks), they grow to an average size of 1.65m (5′ 5″) and weight in at 62 kg (137 lbs), which is obviously highly individual.

A Black-shouldered opossum gets as old as 7.83 years

The black-shouldered opossum (Caluromysiops irrupta), also known as the white-eared opossum is an opossum known from western Brazil and southeastern Peru. It was first described by Colin Campbell Sanborn, curator of Field Museum of Natural History, in 1951. The black-shouldered opossum is characterized by a gray coat, gray underbelly, and broad black stripes that extend from the forefeet, meet on the shoulders, run along the midline of the back and then split into parallel stripes that run down the hindfeet. Little is known of the behavior of the black-shouldered opossum. It is nocturnal (active mainly at night) and arboreal (tree-living); it is known to feed on fruits and rodents. The opossum inhabits humid forests. The IUCN classifies it as least concern.
