Habitat
This species primarily inhabits montane rainforests and moss forests in the highlands of New Guinea, typically at elevations between 1,000 and 3,000 meters. It prefers dense undergrowth and leaf litter in cool, moist environments, avoiding lower altitude areas.
Diet
The red-bellied marsupial shrew feeds mainly on insects such as beetles, ants, and earthworms, as well as spiders and other small invertebrates. It is nocturnal, foraging actively on the forest floor at night using its keen sense of smell to locate prey.
Behavior
This shrew is nocturnal and solitary, spending its nights foraging for food in leaf litter while avoiding open areas. It exhibits territorial behavior, marking its range with scent glands, and is generally elusive, relying on quick movements to escape threats. Little is known about social interactions, but it does not form groups.
Conservation Status
The IUCN lists the red-bellied marsupial shrew as Near Threatened, with a decreasing population trend due to habitat loss from logging and agriculture. Major threats include fragmentation of montane forests and potential impacts from climate change.
