description Common shrew opossum Overview

The common shrew opossum, scientifically known as Caenolestes obscurus, is a small marsupial native to the Andes mountains in South America. It inhabits dense, moist forests in Colombia and Ecuador, where it navigates the undergrowth. The species possesses a long, pointed snout and small eyes, physical traits suited for its primarily insectivorous diet. As a member of the order Paucituberculata, it represents one of the few surviving non-Australian marsupial lineages.

help Common shrew opossum FAQ

Where does the common shrew opossum live?

The common shrew opossum inhabits the Andes mountains of Colombia and Ecuador, typically at high-elevation cloud forest and páramo habitats. It is adapted to cool, moist montane environments where dense vegetation provides cover for its ground-dwelling, insect-hunting lifestyle.

Is the common shrew opossum actually a marsupial or a true shrew?

Despite its name, the common shrew opossum is a marsupial, belonging to the order Paucituberculata, not a placental shrew. It is one of only a handful of surviving species in this ancient marsupial lineage, making it evolutionarily distinct from the true shrews of the Northern Hemisphere.

What does the common shrew opossum eat?

The common shrew opossum is primarily insectivorous, using its elongated snout to probe leaf litter and soil for insects, larvae, and other small invertebrates. Its diet may also include worms and similar soft-bodied prey found in the damp forest-floor environment of its Andean habitat.

How is the common shrew opossum related to other marsupials?

The common shrew opossum belongs to the family Caenolestidae, a group of small, primitive marsupials sometimes called shrew opossums that are found only in South America. They are only distantly related to the more familiar Australian marsupials like kangaroos and koalas, and even to the opossums of the Didelphidae family, representing a separate and ancient evolutionary branch.
