Trichosurus
The brushtail possums are the members of the genus ''Trichosurus'' in the Phalangeridae, a family of marsupials. They are native to Australia (including Tasmania) and some small nearby islands. Unique among marsupials, they have shifted the hypaxial muscles from the epipubic to the pelvis, much like in placental mammals, meaning that their breathing cycle is more similar to the latter than to that of other non-eutherian mammals. In general, they are more terrestrially oriented than other possums, and in some ways might parallel primates. The genus contains these species: * Northern brushtail possum, ''T. arnhemensis'' * Short-eared possum, ''T. caninus'' * Mountain brushtail possum, ''T. cunninghami'' * Coppery brushtail possum, ''T. johnstonii'' *Common brushtail possum The common brushtail possum (''Trichosurus vulpecula'', from the Ancient Greek, Greek for "furry tailed" and the Latin for "little fox", previously in the genus ''Phalangista'') is a nocturnal, semiarborea ...

Common Brushtail Possum
The common brushtail possum (''Trichosurus vulpecula'', from the Ancient Greek, Greek for "furry tailed" and the Latin for "little fox", previously in the genus ''Phalangista'') is a nocturnal, semiarboreal marsupial of the family Phalangeridae, native to Australia and Invasive species, invasive in New Zealand, and the second-largest of the Phalangeriformes, possums. Like most possums, the common brushtail possum is nocturnal. It is mainly a folivore, but has been known to eat small mammals such as rats. In most Australian habitats, eucalyptus leaves are a significant part of the diet, but rarely the sole item eaten. Its tail is Prehensile tail, prehensile and naked on its lower underside. The four colour variations are silver-grey, brown, black, and gold. It is the Australian marsupial most often seen by city dwellers, as it is one of few that thrive in cities and a wide range of natural and human-modified environments. Around human habitations, common brushtails are inventive ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Northern Brushtail Possum
The northern brushtail possum (''Trichosurus arnhemensis'') is a nocturnal marsupial inhabiting northern Australia. The northern brushtail possum is sometimes considered a species; however, more often than not is considered a subspecies of the common brushtail possum (''Trichosurus vulpecula arnhemensis''). Lifestyle Possums are nocturnal in nature, so feed between dawn and dusk. They are territorial creatures and can be found alone or in family groups. Appearance Its fur is a grey in colour, with a white underbelly and pink skin. The northern brushtail possum can grow up to in length, not including its tail, and is around the size of a small cat. Unlike its relatives and despite what its name suggests, the northern brushtail possum does not have a bushy tail. Lifespan and reproduction The northern brushtail possum breeds year-round, with a gestation period around 17–18 days and pouch period of 4–5 months. It can live up to 15 years. Diseases Many of the NT poss ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phalangeridae
The Phalangeridae are a family of mostly nocturnal marsupials native to Australia, New Guinea, and Eastern Indonesia, including the cuscuses, brushtail possums, and their close relatives. Considered a type of possum, most species are arboreal, and they inhabit a wide range of forest habitats from alpine woodland to eucalypt forest and tropical jungle. Many species have been introduced to various non-native habitats by humans for thousands of years. Characteristics Phalangerids are relatively large, compared with other possums. The smallest species, the Sulawesi dwarf cuscus, is cat-sized, averaging in length, while the largest, the black-spotted cuscus, is around long, and weighs . Besides the large size, other key features distinguishing phalangerids from other possums include the presence of bare skin on at least part of the tail, and low-crowned molar teeth. They have claws on the fore feet, but none on the hind feet, although these do have an opposable first toe to help ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coppery Brushtail Possum
The coppery brushtail possum (''Trichosurus johnstonii'') is a species of marsupial possum in the family Phalangeridae. Coppery brushtails are found within the Atherton Tablelands area of Queensland, in northeastern Australia. These mammals inhabit rainforest ecosystems, living within the tree canopy. Though they have a restricted distribution, they are locally common. This population is often considered a subspecies of '' T. vulpecula''. Description Coppery brushtail possums have a typical length of and weigh , with males being larger and heavier than females. Ecology Like the common brushtail possum, coppery brushtails are nocturnal, and live in dens, which are usually tree hollows. At night, they still spend half of their time resting to conserve energy, and the other half in foraging. In feeding experiments, in selecting their food, these possums may tend to select a mix of plant materials with detoxification Detoxification or detoxication (detox for short) is the ...

Mountain Brushtail Possum
The mountain brushtail possum, or southern bobuck (''Trichosurus cunninghami''), is a nocturnal, semi-arboreal marsupial of the family Phalangeridae native to southeastern Australia. It was not described as a separate species until 2002. Taxonomy In 2002, based upon morphometric differences, the mountain brushtail possum, ''Trichosurus caninus'', was proposed to be reclassified into two distinct species. The northern form was to retain the binomial name ''T. caninus'', but was henceforth to be known as the short-eared possum. The southern population, prevalent in the Victorian Alps, was to retain its already designated common name mountain brushtail possum, but assigned a new binomial, ''T. cunninghami''. However, genetic divergence between ''T. caninus'' and the putative ''T. cunninghami'' may not support a case for the establishment of a new species. In 2005, a colony of bobucks was discovered in swamp coastal habitat in south-west Gippsland, Victoria ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Short-eared Possum
The short-eared possum (''Trichosurus caninus'') is a species of marsupial in the family Phalangeridae, endemic to Australia. Found north of Sydney, New South Wales New South Wales (commonly abbreviated as NSW) is a States and territories of Australia, state on the Eastern states of Australia, east coast of :Australia. It borders Queensland to the north, Victoria (state), Victoria to the south, and South ..., on Australia’s eastern coast, the species was once classed under the mountain brushtail possum, its closest relative. In the wild, they can live for up to 17 years (possibly longer in captivity), maintain a stable territory, and invest significant energy and time rearing their young. Short-eared possums are most commonly found along the southeastern coast of the Australian continent, where they reside in wet rainforests and humid, dense thickets.

Epipubic
Epipubic bones are a pair of bones projecting forward from the pelvic bones of modern marsupials, monotremes and fossil mammals like multituberculates, and even basal eutherians (the ancestors of placentals, who lack them). They first occur in non-mammalian cynodonts such as tritylodontids, suggesting that they are a synapomorphy between them and Mammaliformes. They were first described as early as 1698, but to date, their function(s) remain unresolved. Epipubic bones are often called ''marsupial bones'' because they support the mother's pouch in modern marsupials ("''marsupium''" is Latin for "pouch"). Function Some writers have suggested that the epipubic bones are a part of a kinetic link stretching from the femur on one side, to the ribs on the opposite side. This linkage is formed by a series of muscles: Each epipubic bone is connected to the femur by the pectineus muscle, and to the ribs and vertebrae by the pyramidalis, rectus abdominis, and external and intern ...

Marsupial
Marsupials are a diverse group of mammals belonging to the infraclass Marsupialia. They are natively found in Australasia, Wallacea, and the Americas. One of marsupials' unique features is their reproductive strategy: the young are born in a relatively undeveloped state and then nurtured within a pouch on their mother's abdomen. Extant marsupials encompass many species, including Kangaroo, kangaroos, Koala, koalas, Opossum, opossums, Phalangeriformes, possums, Tasmanian devil, Tasmanian devils, Wombat, wombats, Wallaby, wallabies, and Bandicoot, bandicoots. Marsupials constitute a clade stemming from the last common ancestor of extant Metatheria, which encompasses all mammals more closely related to marsupials than to Placentalia, placentals. The evolutionary split between placentals and marsupials occurred 125-160 million years ago, in the Middle Jurassic-Early Cretaceous period. Presently, close to 70% of the 334 extant marsupial species are concentrated on the Australian ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eutheria
Eutheria (from Greek , 'good, right' and , 'beast'; ), also called Pan-Placentalia, is the clade consisting of Placentalia, placental mammals and all therian mammals that are more closely related to placentals than to marsupials. Eutherians are distinguished from non-eutherians by various phenotypic traits of the feet, ankles, jaws and teeth. All extant eutherians lack epipubic bones, which are present in all other living mammals (marsupials and monotremes). This allows for expansion of the abdomen during pregnancy, though epipubic bones are present in many primitive eutherians. Eutheria was named in 1872 by Theodore Gill; in 1880, Thomas Henry Huxley defined it to encompass a more broadly defined group than Placentalia. The earliest unambiguous eutherians are known from the Early Cretaceous Yixian Formation of China, dating around 120 million years ago. Two tribosphenic mammals, ''Durlstodon'' and ''Durlstotherium'' from the Berriasian age (~145–140 million years ago) of t ...

Primates
Primates is an order of mammals, which is further divided into the strepsirrhines, which include lemurs, galagos, and lorisids; and the haplorhines, which include tarsiers and simians ( monkeys and apes). Primates arose 74–63 million years ago first from small terrestrial mammals, which adapted for life in tropical forests: many primate characteristics represent adaptations to the challenging environment among tree tops, including large brain sizes, binocular vision, color vision, vocalizations, shoulder girdles allowing a large degree of movement in the upper limbs, and opposable thumbs (in most but not all) that enable better grasping and dexterity. Primates range in size from Madame Berthe's mouse lemur, which weighs , to the eastern gorilla, weighing over . There are 376–524 species of living primates, depending on which classification is used. New primate species continue to be discovered: over 25 species were described in the 2000s, 36 in the ...

Pelvis
The pelvis (: pelves or pelvises) is the lower part of an Anatomy, anatomical Trunk (anatomy), trunk, between the human abdomen, abdomen and the thighs (sometimes also called pelvic region), together with its embedded skeleton (sometimes also called bony pelvis or pelvic skeleton). The pelvic region of the trunk includes the bony pelvis, the pelvic cavity (the space enclosed by the bony pelvis), the pelvic floor, below the pelvic cavity, and the perineum, below the pelvic floor. The pelvic skeleton is formed in the area of the back, by the sacrum and the coccyx and anteriorly and to the left and right sides, by a pair of hip bones. The two hip bones connect the spine with the lower limbs. They are attached to the sacrum posteriorly, connected to each other anteriorly, and joined with the two femurs at the hip joints. The gap enclosed by the bony pelvis, called the pelvic cavity, is the section of the body underneath the abdomen and mainly consists of the reproductive organs and ...
