A Black-shouldered opossum (Caluromysiops irrupta) usually gives birth to around 2 babies.

Upon birth, they weight 2 grams (0 lbs) and measure 1 cm (0′ 1″). They are a member of the Didelphidae family (genus: Caluromysiops). An adult Black-shouldered opossum grows up to a size of 23.4 cm (0′ 10″).

They weight in at 62 kg (137 lbs), which is obviously highly individual, and reach an average age of 75 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.
