Notoryctes Typhlops
The southern marsupial mole (''Notoryctes typhlops''), also known as the itjaritjari () or itjari-itjari, is a mole-like marsupial found in the western central deserts of Australia. It is extremely adapted to a burrowing way of life. It has large, shovel-like forepaws and silky fur, which helps it move easily. It also lacks complete eyes as it has little need for them. It feeds on earthworms and larvae. History of discovery Although the southern marsupial mole was probably known by Aboriginal Australians for thousands of years, the first specimen examined by the scientific community was collected in 1888. Stockman W. Coulthard made the discovery on Idracowra Pastoral Lease in the Northern Territory by following some unusual prints that lead him to the animal lying under a tussock. Not knowing what to do with the strange creature, he wrapped it in a kerosene soaked rag, placed it in a revolver cartridge box and forwarded it to E. C. Stirling, the Director of the South Australia ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Notoryctes Skeleton
Marsupial moles, the Notoryctidae , are highly specialized marsupial mammals, known from two species found at the Australian interior. * ''Notoryctes typhlops'' (southern marsupial mole, known as the ''itjaritjari'' by the Pitjantjatjara and Yankunytjatjara people in Central Australia). * ''Notoryctes caurinus'' (northern marsupial mole, also known as the ''kakarratul'') Notoryctids are small, fossorial mammals that anatomically converge on other fossorial (and distantly related) mammals, such as living golden moles (Chrysochloridae) and extinct epoicotheres (Pholidota). Characteristics In an example of convergent evolution, notoryctids resemble (and fill the ecological niche of) moles from North America and Eurasia and golden moles from Southern Africa. Like chrysochlorids and epoicotheres, notoryctids use their forelimbs and enlarged central claws to dig in a parasagittal (i.e., up and down) plane, as opposed to the "lateral scratch" style of digging that characterizes talpi ...

Edward Charles Stirling
Sir Edward Charles Stirling (8 September 1848 – 20 March 1919) was an Australian anthropology, anthropologist and the first professor of physiology at the University of Adelaide. Early life Stirling was born at "The Lodge" Strathalbyn, South Australia, the eldest son of the Edward Stirling (politician), Hon. Edward Stirling and his wife Harriett, ''née'' TaylorHans Mincham'Stirling, Edward (1804–1873)' Australian Dictionary of Biography, Volume 6, Melbourne University Press, 1976, pp 200–201.

Yalkaparidon
''Yalkaparidon'' is an extinct genus of Australian marsupials, first described in 1988 and known only from the Oligo-Miocene deposits of Riversleigh, northwestern Queensland, Australia. Species Two species, ''Y. coheni'' and ''Y. jonesi'', have so far been described. Numerous isolated teeth and jaw bones of ''Yalkaparidon'' are known, but only a single skull (of ''Y. coheni'') has so far been recovered. Etymology The generic name ''Yalkaparidon'' comes from an aboriginal word for boomerang, alluding to the boomerang-like shape of its molars when seen in occlusal view, and the Greek word for tooth. Characteristics and classification These specimens of ''Yalkaparidon'' exhibit a melange of characters: the molars are zalambdodont (a distinctive tooth type also found in the marsupial mole ''Notoryctes'', the living placental ' insectivores' ''Solenodon'', tenrecs and golden moles, as well as a number of fossil groups); the incisors are very large and hypselodont (open-rooted ...

Great Victoria Desert
The Great Victoria Desert is a sparsely populated desert ecoregion and interim Australian bioregion in Western Australia and South Australia. History In 1875, British-born Australian explorer Ernest Giles became the first European to cross the desert. He named the desert after the then-reigning monarch, Queen Victoria. In 1891, David Lindsey's expedition traveled across this area from north to south. Frank Hann was looking for gold in this area between 1903 and 1908. Len Beadell explored the area in the 1960s. Location and description The Great Victoria is the largest desert in Australia, and consists of many small sandhills, grassland plains, areas with a closely packed surface of pebbles (called desert pavement or gibber plains), and salt lakes. It is over wide (from west to east) and covers an area of from the Eastern Goldfields region of Western Australia to the Gawler Ranges in South Australia. The Western Australian mulga shrublands ecoregion lies to the west, the ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Triodia (plant Genus)
''Triodia'' is a large genus of hummock-forming bunchgrass endemic to Australia. They are known by the common name spinifex, although they are not a part of the coastal genus '' Spinifex''. Many of the soft-leaved members of this species were formerly included in the genus ''Plectrachne''. It is known as ''tjanpi'' in central Australia, and is used for basket weaving by the women of various Aboriginal Australian peoples. A multiaccess key (SpiKey) is available as a free application for identifying the ''Triodia'' of the Pilbara (28 species and one hybrid). Description ''Triodia'' is a perennial Australian tussock grass that grows in arid regions. Its leaves (30–40 centimetres long) are subulate ( awl-shaped, with a tapering point). The leaf tips, that are high in silica, can break off in the skin, leading to infections. Uses Spinifex has traditionally had many uses for Aboriginal Australians. The seeds were collected and ground to make seedcakes. Spinifex resin was a ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Eremitalpa Granti Namibensis
Grant's golden mole (''Eremitalpa granti''; colloquially also: ''dune shark'') is a golden mole species. It is the only member of the genus ''Eremitalpa''. Attributes Like all other golden moles, the build of these animals is similar to the moles, though they are not closely related, and are adapted to a life of digging. The front extremities are remodeled to digging claws; in contrast to most other species of its family, they have three claws each. The tail is physically not visible, there are no auricles, the eyes are covered with fur, and the mouth is bearing a leather-like pad, which also serves for digging. Grant's golden moles have long silky fur, which is colored gray on cubs and sandy on older animals. With a length of 7.5 to 9 cm and a weight of 15 to 25 g it is the smallest member of its species. Geographical distribution and habitat Grant's golden mole lives on the western coast of South Africa and in south western Namibia. Its natural habitat is dry areas, mos ...

Namib Desert Golden Mole
The Namib ( ; pt, Namibe) is a coastal desert in Southern Africa. The name is of Khoekhoegowab origin and means "vast place". According to the broadest definition, the Namib stretches for more than along the Atlantic coasts of Angola, Namibia, and South Africa, extending southward from the Carunjamba River in Angola, through Namibia and to the Olifants River in Western Cape, South Africa. The Namib's northernmost portion, which extends from the Angola-Namibia border, is known as Moçâmedes Desert, while its southern portion approaches the neighboring Kalahari Desert. From the Atlantic coast eastward, the Namib gradually ascends in elevation, reaching up to inland to the foot of the Great Escarpment. Annual precipitation ranges from in the most arid regions to at the escarpment, making the Namib the only true desert in southern Africa. Having endured arid or semi-arid conditions for roughly 55–80 million years, the Namib may be the oldest desert in the world and conta ...

Pinnae
The auricle or auricula is the visible part of the ear that is outside the head. It is also called the pinna (Latin for "wing" or "fin", plural pinnae), a term that is used more in zoology. Structure The diagram shows the shape and location of most of these components: * ''antihelix'' forms a 'Y' shape where the upper parts are: ** ''Superior crus'' (to the left of the ''fossa triangularis'' in the diagram) ** ''Inferior crus'' (to the right of the ''fossa triangularis'' in the diagram) * ''Antitragus'' is below the ''tragus'' * ''Aperture'' is the entrance to the ear canal * ''Auricular sulcus'' is the depression behind the ear next to the head * ''Concha'' is the hollow next to the ear canal * Conchal angle is the angle that the back of the ''concha'' makes with the side of the head * ''Crus'' of the helix is just above the ''tragus'' * ''Cymba conchae'' is the narrowest end of the ''concha'' * External auditory meatus is the ear canal * ''Fossa triangularis'' is the depress ...

Jacobson's Organ
The vomeronasal organ (VNO), or Jacobson's organ, is the paired auxiliary olfactory (smell) sense organ located in the soft tissue of the nasal septum, in the nasal cavity just above the roof of the mouth (the hard palate) in various tetrapods. The name is derived from the fact that it lies adjacent to the unpaired vomer bone (from Latin 'plowshare', for its shape) in the nasal septum. It is present and functional in all snakes and lizards, and in many mammals, including cats, dogs, cattle, pigs, and some primates. Some humans may have physical remnants of a VNO, but it is vestigial and non-functional. The VNO contains the cell bodies of sensory neurons which have receptors that detect specific non-volatile (liquid) organic compounds which are conveyed to them from the environment. These compounds emanate from prey, predators, and the compounds called sex pheromones from potential mates. Activation of the VNO triggers an appropriate behavioral response to the presence of one o ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Vibrissae
Vibrissae (; singular: vibrissa; ), more generally called Whiskers, are a type of stiff, functional hair used by mammals to sense their environment. These hairs are finely specialised for this purpose, whereas other types of hair are coarser as tactile sensors. Although whiskers are specifically those found around the face, vibrissae are known to grow in clusters at various places around the body. Most mammals have them, including all non-human primates and especially nocturnal mammals. Whiskers are sensitive tactile hairs that aid navigation, locomotion, exploration, hunting, social touch and perform other functions. This article is primarily about the specialised sensing hairs of mammals, but some birds, fish, insects, crustaceans and other arthropods are known to have similar structures also used to sense the environment. Etymology Vibrissae (from Latin 'to vibrate') from the characteristic motion seen in a small rodent that is otherwise sitting still. In medicine, t ...
