Habitat
This species inhabits tropical and subtropical forests, savannas, and grasslands in South America, primarily in Brazil, Bolivia, and Peru. It prefers moist environments with dense undergrowth for cover and is often found near water sources or in areas with abundant insect life. They are adaptable to disturbed habitats like agricultural edges but avoid open, arid regions.
Diet
The Sepia short-tailed opossum is omnivorous, feeding primarily on insects such as beetles and ants, as well as small vertebrates like frogs and lizards. It also consumes fruits, seeds, and occasionally carrion, foraging actively at night to avoid competition. Feeding behavior involves quick, ground-level searches in leaf litter and underbrush.
Behavior
This opossum is primarily nocturnal and solitary, spending its days hidden in burrows or dense vegetation to avoid predators. It exhibits territorial behavior, marking areas with scent glands, and is an agile climber despite its short tail. Notable behaviors include playing dead when threatened and vocalizing with clicks or hisses during interactions.
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 predation by introduced species.
