Habitat
This species primarily inhabits arid and semi-arid regions of western Mexico, including thorn scrub forests, dry tropical forests, and areas with cacti and shrubs. It prefers rocky terrains and can adapt to human-modified environments like agricultural fields. Geographic range is limited to elevations below 1,500 meters.
Diet
The grayish mouse opossum is omnivorous, feeding on insects such as beetles and crickets, fruits like those from cacti, and occasionally small vertebrates or nectar. It forages primarily at night, using its keen senses to locate food in underbrush and trees. Feeding behavior includes caching food items for later use.
Behavior
Grayish mouse opossums are solitary and nocturnal, spending their days in nests made of leaves and bark in tree hollows or rock crevices. They are arboreal, using their prehensile tails for balance while climbing, and exhibit territorial behavior by marking areas with scent glands. They are generally quiet but may hiss or play dead when threatened.
Conservation Status
The IUCN status of the grayish mouse opossum is Least Concern, with a stable population trend due to its wide distribution. Major threats include habitat loss from agriculture and urbanization, but it is not currently facing significant declines.
