Macrochelodina
''Chelodina'', collectively known as snake-necked turtles, is a large and diverse genus of long-necked chelid turtles with a complicated nomenclatural history. Although in the past, ''Macrochelodina'' and ''Macrodiremys'' have been considered separate genera and prior to that all the same, they are now considered subgenera of the ''Chelodina'', further ''Macrochelodina'' and ''Macrodiremys'' are now known to apply to the same species, hence ''Chelydera'' is used for the northern snake-necked turtles. ''Chelodina'' is an ancient group of chelid turtles native to Australia, New Guinea, the Indonesian Rote Island, and East Timor. The turtles within this subgenus are small to medium-sized with oval shaped carapace. They are side-necked turtles, meaning they tuck their head partially around the side of their body when threatened instead of directly backwards. ''Chelydera'' represents those species that have often been termed the ''Chelodina'' B group or thick necked snake neck tur ...

Chelodina Oblonga
The oblong turtle (''Chelodina oblonga''), also known commonly as the narrow-breasted snake-necked turtle and the southwestern snake-necked turtle, is a species of turtle in the family Chelidae. The species is endemic to the southwestern part of Western Australia. The species has been successfully bred in captivity in Cologne Zoological Garden. While all turtles are popularly believed to be mute, the oblong turtle is known to have a wide range of vocalizations. Etymology The specific name, ''colliei'', is in honor of Scottish physician and naturalist Alexander Collie. Beolens, Bo; Watkins, Michael; Grayson, Michael (2011). ''The Eponym Dictionary of Reptiles''. Baltimore: Johns Hopkins University Press. xiii + 296 pp. . (''Chelodina colliei'', p. 57). Taxonomic history This species has a very complicated taxonomic history, involving many uses of the available names and a number of mistakes in that usage.Thomson, S.A. (2000).

Turtle
Turtles are an order of reptiles known as Testudines, characterized by a special shell developed mainly from their ribs. Modern turtles are divided into two major groups, the Pleurodira (side necked turtles) and Cryptodira (hidden necked turtles), which differ in the way the head retracts. There are 360 living and recently extinct species of turtles, including land-dwelling tortoises and freshwater terrapins. They are found on most continents, some islands and, in the case of sea turtles, much of the ocean. Like other amniotes (reptiles, birds, and mammals) they breathe air and do not lay eggs underwater, although many species live in or around water. Turtle shells are made mostly of bone; the upper part is the domed carapace, while the underside is the flatter plastron or belly-plate. Its outer surface is covered in scales made of keratin, the material of hair, horns, and claws. The carapace bones develop from ribs that grow sideways and develop into broad flat plates th ...

Cann's Snake-necked Turtle
''Chelodina canni'', also known commonly as Cann's snake-necked turtle, is a species of turtle in the family Chelidae. The species is endemic to Australia, where it is found in the northern and northeastern parts of the continent. McCord W, Thomson S (2002). "A new species of ''Chelodina'' (Testudines: Pleurodira: Chelidae) from Northern Australia". ''Journal of Herpetology'' 36 (2): 255-267. It has a narrow zone of hybridization with its related species the eastern snake-necked turtle, '' C. longicollis''. For many years ''C. canni'' was assumed to be the same species as '' C. novaeguineae'' from New Guinea. However, in 2002 it was shown that these two species differ both morphologically and genetically, and therefore ''C. canni'' was separated and described as a unique species.

Chelodina Mccordi
The Roti Island snake-necked turtle (''Chelodina mccordi''), also commonly known as McCord's snakeneck turtle, is a critically endangered turtle species from Rote Island in Indonesia. Taxonomy ''Chelodina mccordi'' belongs to the genus ''Chelodina'' (Australian snake-necked turtles) within the family Chelidae (Austro-South American side-necked turtles). ''Chelodina mccordi'' was originally described from Rote Island but was later split into three subspecies. ''Chelodina mccordi rotensis'' from eastern Rote and ''Chelodina mccordi timorensis'' from Timor. In a recent paper the eastern Rote form was found to be identical to the western form and they were synonymised. This leaves the species with two subspecies one on Rote Island and one on Timor. History The Roti Island snake-necked turtle was split from the New Guinea snake-necked turtle and regarded as distinct species in 1994 after Dr. Anders Rhodin, director of thChelonian Research Foundationin Lunenburg (Massachusetts), f ...

CSIRO ScienceImage 7775 Eastern Snakenecked Turtle
The Commonwealth Scientific and Industrial Research Organisation (CSIRO) is an Australian Government agency responsible for scientific research. CSIRO works with leading organisations around the world. From its headquarters in Canberra, CSIRO maintains more than 50 sites across Australia and in France, Chile and the United States, employing about 5,500 people. Federally funded scientific research began in Australia years ago. The Advisory Council of Science and Industry was established in 1916 but was hampered by insufficient available finance. In 1926 the research effort was reinvigorated by establishment of the Council for Scientific and Industrial Research (CSIR), which strengthened national science leadership and increased research funding. CSIR grew rapidly and achieved significant early successes. In 1949, further legislated changes included renaming the organisation as CSIRO. Notable developments by CSIRO have included the invention of atomic absorption spectroscopy, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Chelidae
Chelidae is one of three living families of the turtle suborder Pleurodira, and are commonly called Austro-South American side-neck turtles. The family is distributed in Australia, New Guinea, parts of Indonesia, and throughout most of South America. It is a large family of turtles with a significant fossil history dating back to the Cretaceous. The family is entirely Gondwanan in origin, with no members found outside Gondwana, either in the present day or as a fossil.Georges, A. & Thomson, S. (2006).
