Linnaeus's mouse opossum (Marmosa murina), also known as the common or murine mouse opossum, is a South American marsupial of the family Didelphidae. [1]
Its range includes Colombia, Mexico, Venezuela, Trinidad and Tobago, Guyana, Suriname, French Guiana, Brazil, eastern Ecuador, eastern Peru, and eastern Bolivia.
This opossum is most commonly sighted near forest streams and human habitation. A nocturnal creature, it shelters during the day in a mesh of twigs on a tree branch, a tree hole, or an old bird's nest.
It eats insects, spiders, lizards, bird's eggs, chicks, and fruits.
Linnaeus's mouse opossum has a gestation period of approximately 13 days, and gives birth to 5–10 young.
The mouse opossum will "play dead" if it thinks that it is in danger, it will even smell as if it were dead.
It is pale beige to grey on its underparts with short, smooth fur. Its face appears to have a black mask on it, its eyes are prominent, and its ears are very upright. Its tail, which females use to carry leaves, is much longer than the rest of its body.
Linnaeus's mouse opossum has a body length of approximately 11–14.5 centimetres (4.3–5.7 in), with a tail of approximately 13.5–21 cm (5.3–8.3 in) long. It weighs about 250 grams (8.8 oz).
Opossums are members of the marsupial order Didelphimorphia endemic to the Americas. The largest order of marsupials in the Western Hemisphere, it comprises 126 species in 18 genera. Opossums originated in South America and entered North America in the Great American Interchange following the connection of North and South America.
The white-bellied woolly mouse opossum is a small pouchless marsupial of the family Didelphidae. It was formerly assigned to the genus Micoureus, which was made a subgenus of Marmosa in 2009. The specific epithet was given in honour of Constance Sladen, wife of the naturalist Percy Sladen. She funded the 1902 expedition which collected the type specimen.
The woolly mouse opossum or long-furred woolly mouse opossum, known locally as the cuíca, is a South American marsupial of the family Didelphidae. Its range includes central Colombia, Venezuela, French Guiana, Guyana, Suriname, eastern Peru, northern Bolivia, and northern Brazil. It was formerly assigned to the genus Micoureus, which was made a subgenus of Marmosa in 2009.
The bare-tailed woolly mouse opossum or short-furred woolly mouse opossum is a South American marsupial of the family Didelphidae. Its range includes Brazil, Colombia, Ecuador, Peru, and Bolivia. It is found in tropical rainforest in the westernmost portion of the Amazon Basin and the eastern foothills of the Andes, at elevations up to 1634 m. It was formerly assigned to the genus Micoureus, which was made a subgenus of Marmosa in 2009.
The Chacoan pygmy opossum is a recently described genus and species of didelphimorph marsupial. The only species in Chacodelphys, C. formosa, was known until 2004 from only one specimen collected in 1920 in the Chaco of Formosa Province, Argentina. The species is gaining popularity as a pocket pet.
The bare-tailed woolly opossum is an opossum from South America. It was first described by Swedish zoologist Carl Linnaeus in 1758. The bare-tailed woolly opossum is characterized by a gray head, brown to gray coat, orange to gray underside and a partially naked tail. It is nocturnal and solitary; there is hardly any social interaction except between mother and juveniles and in mating pairs. The opossum constructs nests in tree cavities, and its litter size ranges from one to seven. Gestation lasts 25 days, and the juveniles exit the pouch after three months; weaning occurs a month later. The bare-tailed woolly opossum inhabits subtropical forests, rainforests, secondary forests, and plantations; its range extends from northern Venezuela to northeastern and southcentral Brazil. The IUCN classifies this opossum as least concern.
The brown four-eyed opossum is a pouchless marsupial of the family Didelphidae. It is found in different forested habitats of Central and South America, from Nicaragua to Brazil and northern Argentina, including southeastern Colombia, Paraguay and eastern Peru and Bolivia, at elevations from sea level to 1,500 m (4,900 ft). 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 (66/sq mi) was reported near Manaus, Brazil. Its karyotype has 2n = 14 and FN = 24.
The 27 species in the genus Marmosa are relatively small Neotropical members of the family Didelphidae. This genus is one of three that are known as mouse opossums. The others are Thylamys and Tlacuatzin, the grayish mouse opossum. Members of the genus Marmosops used to be called "slender mouse opossums", but are now just called "slender opossums". The thirteen members of the Marmosa subgenus Micoureus, known as woolly mouse opossums, were formerly considered to be a separate genus, but were moved into Marmosa in 2009. Based on a comparison of sequences of one mitochondrial and three nuclear genes, three new subgenera, Eomarmosa, Exulomarmosa and Stegomarmosa, were recognized by Voss et al. in 2014. Eomarmosa and Exulomarmosa, as well as Marmosa and Micoureus, are thought to be sister taxa, while Stegomarmosa is viewed as sister to Marmosa plus Micoureus. Exulomarmosa is a mostly trans-Andean clade.
The Patagonian opossum(Lestodelphys halli) is the sole species in genus Lestodelphys.
The heavy-browed mouse opossum, or Anderson's mouse opossum, is a species of opossum in the family Didelphidae. It is endemic to a restricted range in southern Peru. This opossum inhabits forests; it is nocturnal and probably arboreal.
The grayish or gray mouse opossum is a diminutive species of opossum in the family Didelphidae, endemic to Mexico. It is the sole species of its monotypic genus, Tlacuatzin.
The Mexican mouse opossum is a species of North American opossum in the family Didelphidae.
Robinson's mouse opossum is a species of opossum in the family Didelphidae. It is found in Belize, Colombia, Ecuador, Grenada, Honduras, Panama, Peru, Trinidad and Tobago, and Venezuela.
The elegant fat-tailed mouse opossum, also known as the Chilean mouse opossum, is an opossum from central Chile. The type species of Thylamys, it was first described by English naturalist George Robert Waterhouse in 1839. This medium-sized opossum is characterized by black rings around the eyes, white limbs, gray to light brown coat, lighter flanks and underbelly and a thick 12.7–14.6 centimetres (5.0–5.7 in) long tail covered with hairs. It is crepuscular and lives in nests in tree hollows or under rocks and roots. This opossum feeds mainly on arthropods and larvae apart from fruits. Litter size is typically between 11 and 13. The elegant fat-tailed opossum can occur in a variety of habitats – from cloud forests to chaparrals. The IUCN classifies the opossum as least concern.
The white-bellied fat-tailed mouse opossum is a species of opossum in the family Didelphidae. It is found in Argentina, Bolivia, Chile and Peru.
Gracilinanus is a genus of opossum in the family Didelphidae. It was separated from the genus Marmosa in 1989, and has since had the genera Cryptonanus, Chacodelphys, and Hyladelphys removed from it.
The Didelphinae are a subfamily of opossums consisting of 15 genera and 123 species. Specimens have been collected throughout the Americas, but are predominant in South and Central America.
Guiana Amazonian Park is the largest national park of France, aiming at protecting part of the Amazonian forest located in French Guiana which covers 41% of the region. It is the largest park in France as well as the largest park in the European Union and one of the largest national parks in the world.
