How old does a Brown four-eyed opossum get? (age expectancy)

What is the maximal age a Brown four-eyed opossum reaches?

An adult Brown four-eyed opossum (Metachirus nudicaudatus) usually gets as old as 4 years.

When born, they weight 2 grams (0 lbs) and measure 8.9 cm (0′ 4″). As a member of the Didelphidae family (genus: Metachirus), their offspring is 4 babies per pregnancy. Fully grown, they reach a bodylength of 26.1 cm (0′ 11″).

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 Brown four-eyed opossum gets as old as 4 years

The brown four-eyed opossum (Metachirus nudicaudatus) is a pouchless marsupial of the family Didelphidae. It is found in different forested habitats of Central and South America, from Nicaragua to Paraguay and northern Argentina, including southeastern Colombia, western Brazil and eastern Peru and Bolivia, at elevations from sea level to 1500 m. It is the only recognized species in the genus Metachirus, but molecular phylogenetics studies suggest that it should probably be split into several species. Population densities are usually low, and it is uncommon in parts of Central America. A density of 25.6/km2 was reported near Manaus, Brazil. Its karyotype has 2n = 14 and FN = 24.It is a nocturnal, solitary, strongly terrestrial and omnivorous animal, feeding on fruits, small vertebrates and invertebrates.The brown four-eyed opossum builds nests made of leaves and twigs in tree branches or under rocks and logs. It is seasonally polyestrous and the litter size varies from one to nine.The white spot over each eye inspired the common name of “four-eyed opossum”. Its scaly tail is longer than its body.The opossum appears to be mostly insectivorous, though also consumes some types of fruit seeds, small vertebrate creatures like birds and reptiles and invertebrates like crayfish and snails. The brown four-eyed opossum is a host of the Acanthocephalan intestinal parasite Gigantorhynchus ortizi.
