Mammals Of North America
This is a list of North American mammals. It includes all mammals currently found in the United States, St. Pierre and Miquelon, Canada, Greenland, Bermuda, Mexico, Central America, and the Caribbean region, whether resident or as migrants. This article does not include species found only in captivity. Mammal species which became extinct in the last 10,000 to 13,000 years are also included in this article. Each species is listed, with its binomial name. Most established introduced species occurring across multiple states and provinces are also noted. Some species are identified as indicated below: *(A) = Accidental: occurrence based on one or a few records, and unlikely to occur regularly *(E) = Extinct: died out between 13,000 years ago and the present *(Ex) = Extirpated: no longer occurs in area of interest, but other populations exist elsewhere *(I) = Introduced: population established solely as result of direct or indirect human intervention; synonymous with non-native ...

Mammal
Mammals () are a group of vertebrate animals constituting the class Mammalia (), characterized by the presence of mammary glands which in females produce milk for feeding (nursing) their young, a neocortex (a region of the brain), fur or hair, and three middle ear bones. These characteristics distinguish them from reptiles (including birds) from which they diverged in the Carboniferous, over 300 million years ago. Around 6,400 extant species of mammals have been described divided into 29 orders. The largest orders, in terms of number of species, are the rodents, bats, and Eulipotyphla ( hedgehogs, moles, shrews, and others). The next three are the Primates (including humans, apes, monkeys, and others), the Artiodactyla (cetaceans and even-toed ungulates), and the Carnivora ( cats, dogs, seals, and others). In terms of cladistics, which reflects evolutionary history, mammals are the only living members of the Synapsida (synapsids); this clade, toget ...

Brown Four-eyed Opossum
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 Brazil and northern Argentina, including southeastern Colombia, Paraguay 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. It is a nocturnal, solitary, strongly terrestrial and omnivorous animal, feeding on fruits, small vertebrates and invertebrates. The brown four-eyed opossum builds nests made of leaves and twigs in tree branches or under rocks and logs. It is seasonally polyestrous and the litter size varies fro ...

Panama Slender Opossum
The Panama slender opossum (''Marmosops invictus''), also known as the slaty slender mouse opossum, is a species of opossum in the family Didelphidae. It is endemic to Panama, where it has been found in tropical rainforest habitats, including disturbed areas, at elevations from 500 to 1500 m. This opossum is mostly terrestrial in its habits, and feeds on plants and insects. It is vulnerable to deforestation Deforestation or forest clearance is the removal of a forest or stand of trees from land that is then converted to non-forest use. Deforestation can involve conversion of forest land to farms, ranches, or urban use. The most concentrated ....

Robinson's Mouse Opossum
Robinson's mouse opossum (''Marmosa robinsoni'') 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. Robinson's mouse opossums move along tree branches and vines with the help of a prehensile tail and may leap between gaps as they search for fruit and insects. Description ''Marmosa robinsoni'' is typically cinnamon brown with a yellow underside. Its dorsal color varies from russet to gray. The top of the head is generally paler in color than the rest of the body. The black facial mask is always present but varies in size according to the region of that individual. It possesses a prehensile tail about 1.3 times its body length, which is covered in fine white hairs. Its feet are modified for grasping with pads and an opposable hallux. Habitat The species occupies a variety of habitats from sea level to 2,600 m elevation, including lowland and montane moist forests ...

Mexican Mouse Opossum
The Mexican mouse opossum (''Marmosa mexicana'') is a species of North American opossum in the family Didelphidae. Description ''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.

Isthmian Mouse Opossum
The Isthmian mouse opossum (''Marmosa isthmica'') is a species of opossum in the family Didelphidae found in Colombia, Ecuador, and Panama.Fiona A. Reid, ''A field guide to the mammals of Central America & Southeast Mexico'' (OUP USA, 2009)p. 50/ref> Foraging along branches and vines for fruit and insects, with the help of a prehensile tail, ''M. isthmica'' was formerly considered a subspecies of Robinson's mouse opossum (''Marmosa robinsoni'') and is supposed to be similar to it in habit, but following Rossi (2005) it is now deemed a species. In 1935 in the Panama Canal Zone, Enders observed ''Marmosa isthmica'' to build nests with leaves in a nestbox fixed to a tree.Papéis Avulsos de Zoologia: vol. 41 (1999), Issues 1-14, p. 177 Notes References *Gardner, A.

Alston's Mouse Opossum
Alston's mouse opossum (''Marmosa alstoni''), also known as Alston's opossum, is a medium-sized pouchless marsupial of the family Didelphidae. It is arboreal and nocturnal, inhabiting forests from Belize to northern Colombia. The main components of its diet are insects and fruits, but it may also eat small rodents, lizards, and bird eggs. It was formerly assigned to the genus '' Micoureus'', which was made a subgenus of ''Marmosa 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'' (the "fat-tailed mouse opossums") and '' Tlacua ...'' in 2009.

Water Opossum
The water opossum (''Chironectes minimus''), also locally known as the yapok (), is a marsupial of the family Didelphidae.* It is the only living member of its genus, ''Chironectes''. This semiaquatic creature is found in and near freshwater streams and lakes from Mexico through Central and South America to Argentina and is the most aquatic living marsupial (the lutrine opossum also has semiaquatic habits). It is also the only living marsupial in which both sexes have a pouch. The thylacine, commonly referred to as the Tasmanian tiger, also exhibited this trait, but it is now extinct. The water opossum lives in bankside burrows, emerging after dusk to swim and search for fish, crustaceans and other aquatic animals, which it eats on the bank. Origin of the name The local name for the water opossum, "yapok", probably comes from the name of the Oyapok River in French Guiana. Physical appearance The water opossum is a small opossum, 27-32.5 cm long, with a 36–40 cm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bare-tailed Woolly Opossum
The bare-tailed woolly opossum (''Caluromys philander'') 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 (active mainly at night) 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. Names It is called mucura-xixica in Portuguese, zarigüeya lanuda parda in Spanish, and wakaro in th ...
