Trichosurus Vulpecula Skeleton
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, semiarboreal ma ...

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] |
Placental
Placental mammals (infraclass Placentalia ) are one of the three extant subdivisions of the class Mammalia, the other two being Monotremata and Marsupialia. Placentalia contains the vast majority of extant mammals, which are partly distinguished from monotremes and marsupials in that the fetus (biology), fetus is carried in the uterus of its mother to a relatively late stage of development. The name is something of a misnomer, considering that marsupials also nourish their fetuses via a placenta, though for a relatively briefer period, giving birth to less-developed young, which are then nurtured for a period inside the mother's pouch (marsupial), pouch. Placentalia represents the only living group within Eutheria, which contains all mammals that are more closely related to placentals than they are to marsupials. Anatomical features Placental mammals are anatomically distinguished from other mammals by: * a sufficiently wide opening at the bottom of the pelvis to allow the birt ...

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.

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] |
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 ...

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 ...

Breathing
Breathing (spiration or ventilation) is the rhythmical process of moving air into ( inhalation) and out of ( exhalation) the lungs to facilitate gas exchange with the internal environment, mostly to flush out carbon dioxide and bring in oxygen. All aerobic creatures need oxygen for cellular respiration, which extracts energy from the reaction of oxygen with molecules derived from food and produces carbon dioxide as a waste product. Breathing, or external respiration, brings air into the lungs where gas exchange takes place in the alveoli through diffusion. The body's circulatory system transports these gases to and from the cells, where cellular respiration takes place. The breathing of all vertebrates with lungs consists of repetitive cycles of inhalation and exhalation through a highly branched system of tubes or airways which lead from the nose to the alveoli. The number of respiratory cycles per minute is the breathing or respiratory rate, and is one of the fou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

John Gould
John Gould (; 14 September 1804 – 3 February 1881) was an English ornithologist who published monographs on birds, illustrated by plates produced by his wife, Elizabeth Gould (illustrator), Elizabeth Gould, and several other artists, including Edward Lear, Henry Constantine Richter, Joseph Wolf and William Matthew Hart. Because of his 1840s seven-volume series ''The Birds of Australia (Gould), The Birds of Australia'' and its updates he has been considered the father of bird study in Australia, and the Gould League in Australia is named after him. His identification of the birds now nicknamed "Darwin's finches" played a role in the inception of Darwin's theory of evolution by natural selection. Gould's work is referenced in Charles Darwin's book, ''On the Origin of Species''. Early life John Gould was born in Lyme Regis, the first son of a gardener. Both father and son probably had little education. After working on Dowager Lady Poulett's glass house, his father obtained ...
