Northern Snake-necked Turtle
The northern snake-necked turtle or northern long-necked turtle (''Chelodina (Chelydera) rugosa'') is a species of turtle in the family Chelidae or Austro-South American Side-necked Turtles. It is native to northern Australia and southern New Guinea. The species was described in 1890 from material collected in Cape York of Queensland, Australia. The species has in recent years had several species of turtle synonymised with it, the distribution includes northern Australia, Indonesia and Pitcairn. As a member of the sub-family Pleurodira this species is a side-necked turtle and also a snake-necked strike and gape predator. This carnivorous turtle will consume fish, tadpoles, hatchling turtles, worms, crickets, etc. It is not an aggressive species with a biting defense. Individuals tend to flail to escape rather than bite. This species can be found not only in fresh water, but due to the proximity of the south New Guinea coast and close off shore islands, it also can be found in ...

James Douglas Ogilby
James Douglas Ogilby (16 February 1853 – 11 August 1925) was an Australian ichthyologist and herpetologist. Ogilby was born in Belfast, Ireland, and was the son of zoologist William Ogilby and his wife Adelaide, née Douglas. He received his education at Winchester College, England, and Trinity College, Dublin. Ogilby worked for the British Museum before joining the Australian Museum in Sydney. After being let go for drunkenness in 1890, he picked up contract work before joining the Queensland Museum in Brisbane circa 1903. He was the author of numerous scientific papers on reptiles, and he described a new species of turtle and several new species of lizards. Ogilby died on 11 August 1925 and was buried at Toowong Cemetery Toowong Cemetery is a heritage-listed cemetery on the corner of Frederick Street and Mt Coot-tha Road, Toowong, City of Brisbane, Queensland, Australia. It was established in 1866 and formally opened in 1875. It is Queensland's largest cemet .. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chelodina Colliei
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).

Reptiles Described In 1841
Reptiles, as most commonly defined are the animals in the class Reptilia ( ), a paraphyletic grouping comprising all sauropsids except birds. Living reptiles comprise turtles, crocodilians, squamates ( lizards and snakes) and rhynchocephalians (tuatara). As of March 2022, the Reptile Database includes about 11,700 species. In the traditional Linnaean classification system, birds are considered a separate class to reptiles. However, crocodilians are more closely related to birds than they are to other living reptiles, and so modern cladistic classification systems include birds within Reptilia, redefining the term as a clade. Other cladistic definitions abandon the term reptile altogether in favor of the clade Sauropsida, which refers to all amniotes more closely related to modern reptiles than to mammals. The study of the traditional reptile orders, historically combined with that of modern amphibians, is called herpetology. The earliest known proto-reptiles originated ...

Turtles Of Australia
Turtles are an order (biology), order of reptiles known as Testudines, characterized by a special turtle shell, 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 Amniote, 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 Turtle shell#Carapace, carapace, while the underside is the flatter plastron or belly-plate. Its outer surface is covered in scale (anatomy), scales made of keratin, the material of hair, horns, and claws. The carapace bon ...

Chelydera
''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 ...

Billabong
Billabong ( ) is an Australian term for an oxbow lake, an isolated pond left behind after a river changes course. Billabongs are usually formed when the path of a creek or river changes, leaving the former branch with a dead end. As a result of the arid Australian climate in which these "dead rivers" are often found, billabongs fill with water seasonally but can be dry for a greater part of the year. Etymology The etymology of the word ''billabong'' is disputed. The word is most likely derived from the Wiradjuri term ''bilabaŋ'', which means "a watercourse that runs only after rain". It is derived from ''bila'', meaning "river", It may have been combined with ''bong'' or ''bung'', meaning "dead". One source, however, claims that the term is of Scottish Gaelic origin. Billabongs were significant because they held water longer than parts of rivers; it was important for people to identify and name these areas.

Oviparity
Oviparous animals are animals that lay their eggs, with little or no other embryonic development within the mother. This is the reproductive method of most fish, amphibians, most reptiles, and all pterosaurs, dinosaurs (including birds), and monotremes. In traditional usage, most insects (one being ''Culex pipiens'', or the common house mosquito), molluscs, and arachnids are also described as oviparous. Modes of reproduction The traditional modes of reproduction include oviparity, taken to be the ancestral condition, traditionally where either unfertilised oocytes or fertilised eggs are spawned, and viviparity traditionally including any mechanism where young are born live, or where the development of the young is supported by either parent in or on any part of their body. However, the biologist Thierry Lodé recently divided the traditional category of oviparous reproduction into two modes that he named ovuliparity and (true) oviparity respectively. He distinguished the tw ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Friedrich Siebenrock
Friedrich Siebenrock (20 January 1853, Schörfling am Attersee – 28 January 1925, Vienna) was an Austrian herpetologist. Biography He studied zoology at the Universities of Innsbruck and Vienna, afterwards serving as a demonstrator under Carl Brühl at the zootomical institute in Vienna.

Herpetology
Herpetology (from Greek ἑρπετόν ''herpetón'', meaning "reptile" or "creeping animal") is the branch of zoology concerned with the study of amphibians (including frogs, toads, salamanders, newts, and caecilians (gymnophiona)) and reptiles (including snakes, lizards, amphisbaenids, turtles, terrapins, tortoises, crocodilians, and the tuataras). Birds, which are cladistically included within Reptilia, are traditionally excluded here; the scientific study of birds is the subject of ornithology. Thus, the definition of herpetology can be more precisely stated as the study of ectothermic (cold-blooded) tetrapods. Under this definition "herps" (or sometimes "herptiles" or "herpetofauna") exclude fish, but it is not uncommon for herpetological and ichthyological scientific societies to collaborate. Examples include publishing joint journals and holding conferences in order to foster the exchange of ideas between the fields, as the American Society of Ichthyologists and He ...

Specific Name (zoology)
In zoological nomenclature, the specific name (also specific epithet or species epithet) is the second part (the second name) within the scientific name of a species (a binomen). The first part of the name of a species is the name of the genus or the generic name. The rules and regulations governing the giving of a new species name are explained in the article species description. For example, the scientific name for humans is ''Homo sapiens'', which is the species name, consisting of two names: ''Homo'' is the " generic name" (the name of the genus) and ''sapiens'' is the "specific name". Historically, ''specific name'' referred to the combination of what are now called the generic and specific names. Carl Linnaeus, who formalized binomial nomenclature, made explicit distinctions between specific, generic, and trivial names. The generic name was that of the genus, the first in the binomial, the trivial name was the second name in the binomial, and the specific the proper term for ...

International Commission On Zoological Nomenclature
The International Commission on Zoological Nomenclature (ICZN) is an organization dedicated to "achieving stability and sense in the scientific naming of animals". Founded in 1895, it currently comprises 26 commissioners from 20 countries. Organization The ICZN is governed by the "Constitution of the ICZN", which is usually published together with the ICZN Code. Members are elected by the Section of Zoological Nomenclature, established by the International Union of Biological Sciences (IUBS). The regular term of service of a member of the Commission is six years. Members can be re-elected up to a total of three full six-year terms in a row. After 18 continuous years of elected service, a break of at least three years is prescribed before the member can stand again for election. Activities Since 2014, the work of the Commission is supported by a small secretariat based at the National University of Singapore, in Singapore. Previously, the secretariat was based in London and fu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pleurodira
The Pleurodira are one of the two living suborders of turtles, the other being the Cryptodira. The division between these two suborders represents a very deep evolutionary divide between two very different types of turtles. The physical differences between them, although anatomical and largely internal, are nonetheless significant, and the zoogeographic implications of them are substantial. The Pleurodira are known more commonly as the side-necked turtles and the name Pleurodira quite literally translates to side neck, whereas the Cryptodira are known as hidden-necked turtles. The Pleurodira turtles are currently restricted to freshwater habitats in the Southern Hemisphere, largely to Australia, South America, and Africa. Within the Pleurodira, three living families are represented: Chelidae, also known as the Austro-South American side-necked turtles, the Pelomedusidae, also known as the African mud terrapins, and the Podocnemididae, also known as the American side-neck river tur ...
