They have a slender body with short limbs and a long, prehensile tail. Their fur is dense and soft, usually gray or brown in color, with a lighter underbelly. They have large eyes and ears, which are adaptations for their nocturnal lifestyle.
These opossums are omnivorous, feeding on a variety of foods including insects, fruits, nectar, and small vertebrates. They are primarily insectivorous, with insects making up a significant portion of their diet. They are skilled climbers and spend most of their time in trees, using their sharp claws and prehensile tail to grip branches. They are also known to build nests in tree hollows or leaf litter.
Reproduction in Robinson’s Mouse Opossum occurs throughout the year, with females giving birth to litters of 4 to 6 young after a gestation period of around 14 days. The young are born undeveloped and crawl into the mother’s pouch where they continue to develop for several weeks. They stay in the pouch for approximately 60 days before venturing out on their own. The lifespan of Robinson’s Mouse Opossum is relatively short, with individuals typically living for about 2 to 3 years in the wild.

Another unique characteristic of Robinson’s Mouse Opossum is its small size. It is one of the smallest opossum species, with adults weighing only around 20 to 40 grams. Their small size allows them to navigate through the dense vegetation of the rainforest and access food sources that may be inaccessible to larger animals.
Robinson’s Mouse Opossum is also known for its nocturnal and arboreal lifestyle. They are primarily active at night, using their keen sense of smell and hearing to locate prey and navigate through their environment. They are skilled climbers and spend most of their time in trees, using their prehensile tail to grip branches and move with agility.
Awesome Facts about Robinson’s Mouse Opossum
One of the awesome facts about Robinson’s Mouse Opossum is its ability to rotate its hind feet 180 degrees. This unique adaptation allows them to climb trees with ease and move in any direction without having to reposition their body. It gives them a great advantage when navigating through the dense vegetation of the rainforest.
Another amazing ability of Robinson’s Mouse Opossum is its capability to hang upside down by its tail. Their prehensile tail acts as an extra limb, providing stability and balance while they hang from branches. This adaptation allows them to access food sources that may be located on the underside of branches or leaves.
The prehensile tail of Robinson’s Mouse Opossum is not only used for hanging, but also for gripping branches. It is highly flexible and can be wrapped around branches to provide a secure grip.

This helps them establish and maintain their home range, as well as communicate with other individuals in the area.
Robinson’s Mouse Opossum has the ability to enter torpor, a state of reduced metabolic activity, in order to conserve energy. During periods of food scarcity or unfavorable environmental conditions, they can lower their metabolic rate and enter a state of dormancy. This allows them to conserve energy until conditions improve and food becomes more readily available.
Fascinating Facts about Robinson’s Mouse Opossum
One fascinating fact about Robinson’s Mouse Opossum is its unique dental formula. They have a total of 50 teeth, with a dental formula of 5/4, 1/1, 3/3, 4/4. This dental formula is different from other opossum species and is an adaptation for their insectivorous diet.
Another fascinating ability of Robinson’s Mouse Opossum is its ability to regenerate damaged tissue. If they sustain an injury or lose part of their tail, they have the ability to regenerate the tissue and restore function. This regenerative ability is not common among mammals and is a unique characteristic of this species.
Robinson’s Mouse Opossum can also produce a musky odor to deter predators. When threatened, they can release a strong-smelling secretion from their scent glands, which acts as a deterrent to potential predators. This odor is often enough to discourage predators from attacking, allowing the opossum to escape unharmed.
Great Facts about Robinson’s Mouse Opossum
