The brown four-eyed opossum (Metachirus nudicaudatus) is a pouchless marsupial of the family Didelphidae. It is found in different forested habitats of Central and South America, from Nicaragua to Paraguay and northern Argentina, including southeastern Colombia, western Brazil and eastern Peru and Bolivia, at elevations from sea level to 1500 m. It is the only recognized species in the genus Metachirus, but molecular phylogenetics studies suggest that it should probably be split into several species. Population densities are usually low, and it is uncommon in parts of Central America. A density of 25.6/km2 was reported near Manaus, Brazil. Its karyotype has 2n = 14 and FN = 24.
The white spot over each eye inspired the common name of "four-eyed opossum". Its scaly tail is longer than its body.
