Habitat
This species primarily inhabits tropical and subtropical forests, savannas, and grasslands in South America, particularly in Brazil and surrounding regions. It adapts to a range of terrains from dense underbrush to urban edges, preferring areas with ample cover and proximity to water sources.
Diet
The gray short-tailed opossum is omnivorous, feeding on insects, spiders, and other invertebrates, as well as fruits, seeds, and small vertebrates like lizards or frogs. It forages primarily at night, using its keen sense of smell to locate food in leaf litter and underbrush. Feeding behavior includes both scavenging and active hunting of live prey.
Behavior
Gray short-tailed opossums are solitary and nocturnal, spending their days hidden in burrows or dense vegetation and emerging at night to forage. They exhibit territorial behavior, marking areas with scent glands, and are generally non-aggressive, relying on playing dead as a defense mechanism. They are agile climbers but prefer ground-level activity in their habitats.
Conservation Status
The IUCN status is Least Concern, with a stable population trend due to its wide distribution and adaptability. Major threats include habitat loss from deforestation and urbanization, though it is not currently facing significant decline.
