The Mexican mouse opossum (Marmosa mexicana) is a species of Central American opossum in the family Didelphidae. 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 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. An example of its habitat is the Petenes mangroves ecoregion of the Yucatán 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. The forepaws of M. mexicana have remarkable manipulative powers. It uses this ability to burrow in the ground. The burrow can be 30 mm in diameter and 40 cm in length. The mouse-opossum then fills the burrow with leaves to create a nest. More commonly it creates nests in trees especially abandoned bird nests. When threatened it can become aggressive, opening its mouth and hissing or a clicking noise Like all marsupials, gestation is probably short, with females' giving birth to poorly developed young and most of the development taking place during lactation.[5] It is likely that reproduction is similar to that of Marmosa robinsoni, which gives birth to 6 to 14 young after a gestation
