An adult Gray four-eyed opossum (Philander opossum) usually gets as old as 3.5 years.
When born, they weight 3.5 kg (7.71 lbs) and measure 2.37 meter (7′ 10″). As a member of the Didelphidae family (genus: Philander), a Gray four-eyed opossum caries out around 4 little ones per pregnancy, which happens around 3 times a year. Fully grown, they reach a bodylength of 26.5 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.
