Limnodynastes Dorsalis
''The western banjo frog (Limnodynastes dorsalis)'' is a species of frog from the family Limnodynastidae. The informal names for this species are pobblebonk, sand frog and bullfrog. It is one of the endemic amphibians of Western Australia. A large frog in the family Myobatrachidae, it has sturdy limbs and a head that is triangular. Females are up to 87 mm long, the males are no bigger than 75 mm. The frog is grey or brownish-olive coloured, with irregular blotches and marbling of a very dark or black colour. They have poisonous glands on their calves. The markings are large on the upper surface and smaller at the legs and face. A wide and dark stripe appears across the eye and extends to the fore limb. The underside is pale, white or yellowish, and smooth. The upper surface is also smooth, or may be slightly warty. A large oval bump, the tibial gland, is located on the upper calf of the hind leg. The toes are very slightly webbed, the second toe is perhaps a little long ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Limnodynastes Dorsalis Western Banjo Frog 2 Stirling Range NP II-2010
''Limnodynastes'' (commonly known as the Australian swamp frogs) is a genus of frog native to Australia, southern New Guinea and some Torres Strait Islands. They are ground-dwelling frogs, with no toe pads. The size varies from 45 mm to 90 mm in the giant banjo frog. The webbing on the feet ranges between species, from very little, to almost complete. The tympanum is not visible in any species, except in the woodworker frog, which is sometimes classed in a separate genus ''Megistolotis''. All species construct a foam nest in which the eggs are laid. However, in south-eastern South Australia female striped marsh frog and spotted grass frog lack the flanges of skin on the hands that helps trap the air bubble and do not construct foam nests. Species Following a major revision of amphibians in 2006, two species, the ornate burrowing frog, ''Opisthodon ornatus'' and Spencer's burrowing frog Spencer's burrowing frog (''Platyplectrum spenceri'') is a species of frog native ...

Amphibians Described In 1841
Amphibians are ectothermic, anamniotic, four-limbed vertebrate animals that constitute the class Amphibia. In its broadest sense, it is a paraphyletic group encompassing all tetrapods, but excluding the amniotes (tetrapods with an amniotic membrane, such as modern reptiles, birds and mammals). All extant (living) amphibians belong to the monophyletic subclass Lissamphibia, with three living orders: Anura (frogs and toads), Urodela (salamanders), and Gymnophiona (caecilians). Evolved to be mostly semiaquatic, amphibians have adapted to inhabit a wide variety of habitats, with most species living in freshwater, wetland or terrestrial ecosystems (such as riparian woodland, fossorial and even arboreal habitats). Their life cycle typically starts out as aquatic larvae with gills known as tadpoles, but some species have developed behavioural adaptations to bypass this. Young amphibians generally undergo metamorphosis from an aquatic larval form with gills to an air-breathing a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amphibians Of Western Australia
The Amphibians of Western Australia are represented by two families of frogs. Of the 78 species found, most within the southwest, 38 are unique to the state. 15 of the 30 genera of Australian frogs occur; from arid regions and coastlines to permanent wetlands. Frog species in Western Australia have not suffered the major declines of populations and diversity of many parts of the world. No species is recorded as having become extinct, despite over 50% of recent worldwide extinctions being Australian. Three species are listed as Threatened, two as Vulnerable and '' Anstisia alba'' as Critically endangered. Threats to the species include the fungal disease Chytridiomycosis, though no infection has yet been recorded, and damage to habitat from altered land use and fire regimes. These processes have caused decline in many populations, however, some have successfully colonized newly created habitats such as dams or suburban gardens. Species such as '' Litoria moorei'' (Motorbike ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Great Australian Bight
The Great Australian Bight is a large oceanic bight (geography), bight, or open bay, off the central and western portions of the southern Coast, coastline of mainland Australia. There are two definitions for its extent—one by the International Hydrographic Organization (IHO) and another by the Australian Hydrographic Service (AHS). The bight is generally considered part of the Indian Ocean, although the AHS classifies it as part of the Southern Ocean. Its coastline is characterized by cliff faces and rocky capes, making it an ideal location for whale-watching. This oceanic feature was first encountered by European explorers in 1627, and was accurately charted by English navigator Matthew Flinders in 1802. The Great Australian Bight came into existence about 50 million years ago when the supercontinent Gondwana broke apart, separating Antarctica from Australia. The Bight's waters are highly Biodiversity, biodiverse, especially in zooplankton, due to specific ocean currents. H ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Southwest Australia
Southwest Australia is a biogeographic region in Western Australia. It includes the Mediterranean-climate area of southwestern Australia, which is home to a diverse and distinctive flora and fauna. The region is also known as the Southwest Australia Global Diversity Hotspot. Geography The region includes the Mediterranean forests, woodlands, and scrub ecoregions of Western Australia. The region covers 356,717 km2, consisting of a broad coastal plain 20–120 kilometres wide, transitioning to gently undulating uplands made up of weathered granite, gneiss and laterite. Bluff Knoll in the Stirling Range is the highest peak in the region, at 1,099 metres (3,606 ft) elevation. Desert and xeric shrublands lie to the north and east across the centre of Australia, separating Southwest Australia from the other Mediterranean and humid-climate regions of the continent. Climate The region has a wet-winter, dry-summer Mediterranean climate, one of five such regions in the worl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Banjo
The banjo is a stringed instrument with a thin membrane stretched over a frame or cavity to form a resonator. The membrane is typically circular, and in modern forms is usually made of plastic, where early membranes were made of animal skin. Early forms of the instrument were fashioned by African Americans and had African antecedents. In the 19th century, interest in the instrument was spread across the United States and United Kingdom by traveling shows of the 19th-century minstrel show fad, followed by mass production and mail-order sales, including instructional books. The inexpensive or home-made banjo remained part of rural folk culture, but five-string and four-string banjos also became popular for home parlor music entertainment, college music clubs, and early 20th century jazz bands. By the early 20th century, the banjo was most frequently associated with folk, cowboy music, and country music. By mid-century it had come to be strongly associated with bluegrass. Eventu ...

John Edward Gray
John Edward Gray (12 February 1800 – 7 March 1875) was a British zoologist. He was the elder brother of zoologist George Robert Gray and son of the pharmacologist and botanist Samuel Frederick Gray (1766–1828). The same is used for a zoological name. Gray was keeper of zoology at the British Museum in London from 1840 until Christmas 1874, before the natural history holdings were split off to the Natural History Museum. He published several catalogues of the museum collections that included comprehensive discussions of animal groups and descriptions of new species. He improved the zoological collections to make them amongst the best in the world. Biography Gray was born in Walsall, but his family soon moved to London, where Gray studied medicine. He assisted his father in writing ''The Natural Arrangement of British Plants'' (1821). After being blackballed by the Linnean Society of London, Gray shifted his interest from botany to zoology. He began his zoological ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tibia
The tibia (; : tibiae or tibias), also known as the shinbone or shankbone, is the larger, stronger, and anterior (frontal) of the two Leg bones, bones in the leg below the knee in vertebrates (the other being the fibula, behind and to the outside of the tibia); it connects the knee with the ankle bones, ankle. The tibia is found on the anatomical terms of location#Medial, medial side of the leg next to the fibula and closer to the median plane. The tibia is connected to the fibula by the interosseous membrane of leg, forming a type of fibrous joint called a syndesmosis with very little movement. The tibia is named for the flute ''aulos, tibia''. It is the second largest bone in the human body, after the femur. The leg bones are the strongest long bones as they support the rest of the body. Structure In human anatomy, the tibia is the second largest bone next to the femur. As in other vertebrates the tibia is one of two bones in the lower leg, the other being the fibula, and is a ...
