Habitat
This species primarily inhabits tropical and subtropical forests, savannas, and shrublands in South America, including regions of Brazil, Paraguay, and Argentina. They prefer areas with dense undergrowth and proximity to water sources for cover and foraging. They are adaptable to both forested and more open terrains.
Diet
The Yellow-sided opossum is omnivorous, feeding on insects like beetles and ants, small vertebrates such as lizards and frogs, and plant matter including fruits and seeds. They forage primarily at night, using their keen senses to locate food in leaf litter or on the ground.
Behavior
Yellow-sided opossums are solitary and nocturnal, spending days hidden in burrows or dense vegetation to avoid predators. They exhibit territorial behavior, marking areas with scent glands, and are agile climbers despite being primarily terrestrial. When threatened, they may play dead or emit a foul odor as a defense mechanism.
Conservation Status
The IUCN status is Least Concern, with a stable population trend, though habitat loss due to deforestation and agriculture poses a potential threat.
