Mammal
A mammal () is a vertebrate animal of the Class (biology), class Mammalia (). Mammals are characterised by the presence of milk-producing mammary glands for feeding their young, a broad neocortex region of the brain, fur or hair, and three Evolution of mammalian auditory ossicles, middle ear bones. These characteristics distinguish them from reptiles and birds, from which their ancestors Genetic divergence, diverged in the Carboniferous Period over 300 million years ago. Around 6,640 Neontology#Extant taxon, extant species of mammals have been described and divided into 27 Order (biology), orders. The study of mammals is called mammalogy. The largest orders of mammals, by number of species, are the rodents, bats, and eulipotyphlans (including hedgehogs, Mole (animal), moles and shrews). The next three are the primates (including humans, monkeys and lemurs), the Artiodactyl, even-toed ungulates (including pigs, camels, and whales), and the Carnivora (including Felidae, ...

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. The species is named after Wirt Robinson, the collector of the specimen from which it was first described. 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 was or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Linnaeus's Mouse Opossum
Linnaeus's mouse opossum (''Marmosa murina''), also known as the common or murine mouse opossum, is a South American marsupial of the family Didelphidae. Range and habitat 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 Nocturnality is a ethology, behavior in some non-human animals characterized by being active during the night and sleeping during the day. The common adjective is "nocturnal", versus diurnality, diurnal meaning the opposite. Nocturnal creatur ... creature, it shelters during the day in a mesh of twigs on a tree branch, a tree hole, or an old bird's nest.

Marmosa Zeledoni
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 '' 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''.

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.

Water Opossum
The water opossum (''Chironectes minimus''), also locally known as the yapok (), is a marsupial of the family Didelphidae.* It is the only monotypic species 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 extant marsupial species in which both sexes have a pouch. The now extinct thylacine, commonly referred to as the Tasmanian tiger, also exhibited this trait. The local name for the water opossum, "yapok", may come from the name of the Oyapock River in French Guiana. Physical appearance The water opossum is small, measuring long, with a long tail. The fur is in a marbled grey and black pattern, while the muzzle, eyestripe, and crown are all black. A light band runs across the forehead anterior to the ears, which are rounded and hairless. There are ... [...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 the ...
