Habitat
This species primarily inhabits dry forests, savannas, and shrublands in the Gran Chaco region of South America, including parts of Argentina, Paraguay, and Bolivia. It prefers areas with dense underbrush and thorny vegetation for cover, avoiding open grasslands.
Diet
The Chacoan gracile opossum is omnivorous, feeding on insects like beetles and ants, fruits such as berries, and occasionally small vertebrates like lizards or frogs. It forages at night using its keen sense of smell, often climbing trees or scavenging on the ground.
Behavior
These opossums are nocturnal and solitary, spending most of their time foraging in trees or on the ground with agile movements aided by their prehensile tail. They exhibit minimal territorial behavior, marking areas with scent glands, and are generally elusive, playing dead when threatened. Males may travel more widely than females during mating seasons.
Conservation Status
The IUCN status is Least Concern, but populations may be declining due to habitat loss from deforestation and agriculture in the Chaco region.
