Habitat
This species inhabits dry forests and shrublands in central Brazil, preferring areas with dense vegetation for cover and foraging. It is typically found in regions with sandy soils and sparse trees, avoiding wetter or densely forested areas.
Diet
Karimi's fat-tailed mouse opossum primarily eats insects, spiders, and other small invertebrates, which it hunts at night. It also consumes fruits and seeds when available, using its agile movements to forage in trees and on the ground.
Behavior
It is solitary and nocturnal, spending nights foraging for food and days resting in hidden nests made in tree hollows or dense foliage. The species exhibits territorial behavior, marking areas with scent glands, and is agile, often climbing trees to escape threats. It shows little social interaction outside of mating.
Conservation Status
IUCN status is Least Concern, with a stable population trend, though habitat loss from deforestation poses a potential threat.
