Honey Possum
The honey possum or noolbenger (''Tarsipes rostratus''), is a tiny species of marsupial that feeds on the nectar and pollen of a diverse range of flowering plants. Found in southwest Australia, it is an important pollinator for such plants as ''Banksia attenuata'', ''Banksia coccinea'' and ''Adenanthos cuneatus''. Taxonomy The first description of the diprotodont species was published by Paul Gervais and Jules Verreaux on 3 March 1842, referring to a specimen collected by Verreaux. The lectotype nominated for this species, held in the collection at National Museum of Natural History, France, was collected the Swan River Colony. A description of a second species ''Tarsipes spenserae'', published five days later by John Edward Gray and current until the 1970s, was thought to have been published earlier by T. S. Palmer in 1904 and displaced the usage of ''T. rostratus''. A review by Mahoney in 1984 again reduced ''T. spenserae'' to a synonym for the species, as was the emendation ...

Paul Gervais
Paul Gervais full name François Louis Paul Gervais (26 September 1816 – 10 February 1879) was a French palaeontologist and entomologist. Biography Gervais was born in Paris, where he obtained the diplomas of doctor of science and of medicine, and in 1835 he began palaeontological research as assistant in the laboratory of comparative anatomy at the ''Muséum national d'Histoire naturelle''. In 1841 he obtained the chair of zoology and comparative anatomy at the Faculty of Sciences in Montpellier, of which he was in 1856 appointed dean. In 1848–1852 appeared his important work ''Zoologie et paléontologie françaises'', supplementary to the palaeontological publications of Georges Cuvier and Henri Marie Ducrotay de Blainville; of this a second and greatly improved edition was issued in 1859. In 1865 he accepted the professorship of zoology at the Sorbonne, vacant through the death of Louis Pierre Gratiolet; this post he left in 1868 for the chair of comparative anatomy at the ...

Pseudocheiridae
Pseudocheiridae is a family of arboreal marsupials containing 17 extant species of ringtailed possums and close relatives. They are found in forested areas and shrublands throughout Australia and New Guinea. Characteristics Physically, they appear very similar to the pygmy possums, except for their greater size. Even so, they are relatively small animals, with the largest being cat-sized, and they weigh between 200 grams and 2 kilograms. They have grasping hands and feet with opposable first toes on their hindfeet, and, in all species save the greater glider, a prehensile tail. They are nocturnal, with large eyes. All species feed almost entirely on leaves. To enable them to digest this tough and fibrous food, they have an enlarged cecum containing fermenting bacteria, and, like rabbits, they are coprophagous, passing food through their digestive tracts twice. Their teeth include a battery of grinding molars, and they lack lower canines. Their dental formula is: Most are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dental Formula
Dentition pertains to the development of teeth and their arrangement in the mouth. In particular, it is the characteristic arrangement, kind, and number of teeth in a given species at a given age. That is, the number, type, and morpho-physiology (that is, the relationship between the shape and form of the tooth in question and its inferred function) of the teeth of an animal. Animals whose teeth are all of the same type, such as most non-mammalian vertebrates, are said to have '' homodont'' dentition, whereas those whose teeth differ morphologically are said to have '' heterodont'' dentition. The dentition of animals with two successions of teeth (deciduous, permanent) is referred to as '' diphyodont'', while the dentition of animals with only one set of teeth throughout life is ''monophyodont''. The dentition of animals in which the teeth are continuously discarded and replaced throughout life is termed ''polyphyodont''. The dentition of animals in which the teeth are set in s ...

House Mouse
The house mouse (''Mus musculus'') is a small mammal of the order Rodentia, characteristically having a pointed snout, large rounded ears, and a long and almost hairless tail. It is one of the most abundant species of the genus '' Mus''. Although a wild animal, the house mouse has benefited significantly from associating with human habitation to the point that truly wild populations are significantly less common than the semi-tame populations near human activity. The house mouse has been domesticated as the pet or fancy mouse, and as the laboratory mouse, which is one of the most important model organisms in biology and medicine. The complete mouse reference genome was sequenced in 2002. Characteristics House mice have an adult body length (nose to base of tail) of and a tail length of . The weight is typically . In the wild they vary in color from grey and light brown to black (individual hairs are actually agouti coloured), but domesticated fancy mice and laboratory mice ar ...

Prehensile
Prehensility is the quality of an appendage or organ (anatomy), organ that has Adaptation (biology), adapted for grasping or holding. The word is derived from the Latin term ''prehendere'', meaning "to grasp". The ability to grasp is likely derived from a number of different origins. The most common are tree-climbing and the need to manipulate food. Examples Appendages that can become prehensile include: Uses Prehensility affords animals a great natural advantage in manipulating their environment for feeding, climbing, wikt:dig, digging, and defense. It enables many animals, such as primates, to use tools to complete tasks that would otherwise be impossible without highly specialized anatomy. For example, chimpanzees have the ability to use sticks to obtain termites and larva, grubs in a manner similar to human fishing. However, not all prehensile organs are applied to tool use; the giraffe tongue, for instance, is instead used in feeding and Personal grooming, self-cleaning. ...

Noongar Language
Noongar (; also Nyungar ) is an Australian Aboriginal language or dialect continuum, spoken by some members of the Noongar community and others. It is taught actively in Australia, including at schools, universities and through public broadcasting. The country of the Noongar people is the southwest corner of Western Australia. Within that region, many Noongar words have been adopted into English, particularly names of plants and animals. Noongar was first recorded in 1801 by Matthew Flinders, who made a number of word lists. Varieties of the Noongar subgroup It is generally agreed that there was no single, standard Noongar (or Nyungar) language before European settlement: it was a subgroup (or possibly a dialect continuum) of closely related languages, whose speakers were differentiated geographically and, in some cases, by cultural practices. The dialects merged into the modern Noongar language following colonisation. A 1990 conference organised by the Nyoongar Language Proje ...

Ellis Le Geyt Troughton (born in Sydney on 29 April 1893; died 30 November 1974) was an Australian zoologist and mammalogist. Biography Ellis Troughton began to exercise his interest in mammals at fourteen years of age, taking a role at the Australian Museum in 1908. He continued to be employed there as curator after returning from military service as a stretcher bearer in the European war during the years 1917 and 1918. He retired from the museum in 1958.

Gondwana
Gondwana () was a large landmass, often referred to as a supercontinent, that formed during the late Neoproterozoic (about 550 million years ago) and began to break up during the Jurassic period (about 180 million years ago). The final stages of break-up, involving the separation of Antarctica from South America (forming the Drake Passage) and Australia, occurred during the Paleogene. Gondwana was not considered a supercontinent by the earliest definition, since the landmasses of Baltica, Laurentia, and Siberia were separated from it. To differentiate it from the Indian region of the same name (see ), it is also commonly called Gondwanaland. Gondwana was formed by the accretion of several cratons. Eventually, Gondwana became the largest piece of continental crust of the Palaeozoic Era, covering an area of about , about one-fifth of the Earth's surface. During the Carboniferous Period, it merged with Laurasia to form a larger supercontinent called Pangaea. Gondwana (and Pan ...
