Mexican mouse opossum

Marmosa mexicana


Marmosa mexicana is a small to moderate-sized reddish-brown marsupial, varying from bright to dull coloration. Hairs of the back, sides and outer surfaces of legs are lead-colored at the base and tipped with reddish brown. The forehead and nose are paler in color. The eye-rings are black and vary in intensity based on the region of the individual. The cheeks, throat, belly and inner surfaces of legs are yellowish with a median white pectoral area. Body hair continues onto the tail for approximately 10 mm. Its nose is pink, ears are grayish brown, and its tail is a dusky brown. It possesses a prehensile tail of equal length to its body. While appearing naked, the tail in fact has a fine layer of hair. The species is primarily arboreal; it is found from ground level to heights of 30 m in the canopy. It is nocturnal and solitary. Its diet includes insects and fruit. It is believed to construct nests either in burrows or above ground.


This opossum is found in primary and secondary forest, including lowland tropical rainforest, dry deciduous forest, cloud forest, and plantations, as well as in grassland
