Drysdalia Coronoides
The white-lipped snake (''Drysdalia coronoides'') is a small species of venomous snake in the family Elapidae. The species is endemic to south-eastern mainland Australia and Tasmania. Description It is the smallest of three species of snake found in Tasmania and is Australia's most cold-tolerant snake, even inhabiting areas on Mount Kosciuszko above the snow line. Growing to only about in total length (including tail), this snake feeds almost exclusively on skinks. It belongs to the genus ''Drysdalia'', and is often referred to as the whip snake in Tasmania (true whip snakes from Australia are from the genus ''Demansia'' and are only found on the mainland). This species gets its common name from a thin, white line bordered above by a narrow black line that runs along the upper lip. ''D. coronoides'' is viviparous Among animals, viviparity is development of the embryo inside the body of the parent. This is opposed to oviparity which is a reproductive mode in which fe ...

Albert Günther
Albert Karl Ludwig Gotthilf Günther FRS, also Albert Charles Lewis Gotthilf Günther (3 October 1830 – 1 February 1914), was a German-born British zoologist, ichthyologist, and herpetologist. Günther is ranked the second-most productive reptile taxonomist (after George Albert Boulenger) with more than 340 reptile species described. Early life and career Günther was born in Esslingen in Swabia (Württemberg). His father was a ''Stiftungs-Commissar'' in Esslingen and his mother was Eleonora Nagel. He initially schooled at the Stuttgart Gymnasium. His family wished him to train for the ministry of the Lutheran Church for which he moved to the University of Tübingen. A brother shifted from theology to medicine, and he, too, turned to science and medicine at Tübingen in 1852. His first work was "''Ueber den Puppenzustand eines Distoma''". He graduated in medicine with an M.D. from Tübingen in 1858, the same year in which he published a handbook of zoology for students of ...

Endemism
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Reptiles Described In 1858
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, Squamata, squamates (lizards and snakes) and rhynchocephalians (tuatara). As of March 2022, the Reptile Database includes about 11,700 species. In the traditional Linnaean taxonomy, 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 Cladistics, 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 Order (biology), orders, historically combined with that of modern amphibians, is called herpetolo ...

Viviparity
Among animals, viviparity is development of the embryo inside the body of the parent. This is opposed to oviparity which is a reproductive mode in which females lay developing eggs that complete their development and hatch externally from the mother. The term 'viviparity' and its adjective form 'viviparous' derive from the Latin ''vivus'' meaning "living" and ''pario'' meaning "give birth to". Reproductive mode Five modes of reproduction have been differentiated in animals based on relations between zygote and parents. The five include two nonviviparous modes: ovuliparity, with external fertilisation, and oviparity, with internal fertilisation. In the latter, the female lays zygotes as eggs with a large vitellus, yolk; this occurs in all birds, most reptiles, and some fishes. These modes are distinguished from viviparity, which covers all the modes that result in live birth: *Histotrophic viviparity: the zygotes develop in the female's oviducts, but find their nutrients b ...

Common Name
In biology, a common name of a taxon or organism (also known as a vernacular name, English name, colloquial name, country name, popular name, or farmer's name) is a name that is based on the normal language of everyday life; and is often contrasted with the scientific name for the same organism, which is Latinized. A common name is sometimes frequently used, but that is not always the case. In chemistry, IUPAC defines a common name as one that, although it unambiguously defines a chemical, does not follow the current systematic naming convention, such as acetone, systematically 2-propanone, while a vernacular name describes one used in a lab, trade or industry that does not unambiguously describe a single chemical, such as copper sulfate, which may refer to either copper(I) sulfate or copper(II) sulfate. Sometimes common names are created by authorities on one particular subject, in an attempt to make it possible for members of the general public (including such interested par ...

Demansia
''Demansia'' is a genus of venomous snakes of the family Elapidae. Members of the genus are commonly known as whip snakes or whipsnakes, as are members of several other genera. Description All species of the genus ''Demansia'' are gray, brown, gray-green, or beige, save for '' Demansia psammophis'' (yellow-faced whip snake), which may be cream-coloured. Whip snakes are long and slender. They have large eyes and relatively small heads that are only slightly wider than their bodies. All species in the genus ''Demansia'' are venomous. Distribution Whip snakes of the genus ''Demansia'' are found in Australia, Papua New Guinea in the area around Port Moresby, and nearby islands. Diet ''Demansia'' whip snakes eat mainly lizards. These whipsnakes are diurnal (active in the day), and use their keen eyesight to hunt. The prey dies quickly from the effects of the snake's venom. Interaction with humans In 2007 a man died after being bitten by a whip snake in Victoria. Their bites ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Drysdalia
''Drysdalia'' is a genus of snakes, commonly known as crowned snakes, belonging to the family Elapidae. The three species in this genus are venomous snakes, but not considered deadly.

Skink
Skinks are lizards belonging to the family Scincidae, a family in the infraorder Scincomorpha. With more than 1,500 described species across 100 different taxonomic genera, the family Scincidae is one of the most diverse families of lizards. Skinks are characterized by their smaller legs in comparison to typical lizards and are found in different habitats except arctic and subarctic regions. Description Skinks look like lizards of the family Lacertidae (sometimes called ''true lizards''), but most species of skinks have no pronounced neck and relatively small legs. Several genera (e.g., ''Typhlosaurus'') have no limbs at all. This is not true for all skinks, however, as some species such as the red-eyed crocodile skink have a head that is very distinguished from the body. These lizards also have legs that are relatively small proportional to their body size. Skinks' skulls are covered by substantial bony scales, usually matching up in shape and size, while overlapping. Other gen ...

Mount Kosciuszko
Mount Kosciuszko ( ; Ngarigo: , ), previously spelled Mount Kosciusko, is mainland Australia's tallest mountain, at 2,228 metres (7,310 ft) above sea level. It is located on the Main Range of the Snowy Mountains in Kosciuszko National Park, part of the Australian Alps National Parks and Reserves, in New South Wales, Australia, and is located west of Crackenback and close to Jindabyne, near the border with Victoria. Etymology and charting The mountain was named by the Polish explorer Paweł (Paul) Edmund Strzelecki in 1840, in honour of Polish-Lithuanian freedom fighter General Tadeusz Kościuszko, Kościuszko is also a national hero in Lithuania, and Belarus, and hero of the American Revolutionary War because of its perceived resemblance to the Kościuszko Mound in Kraków, Poland. An exploration party led by Strzelecki and James Macarthur beside him with Indigenous guides Charlie Tarra and Jackey set off on what is called Strzelecki’s Southern expedition. Maca ...

Elapidae
Elapidae (, commonly known as elapids ; grc, ἔλλοψ ''éllops'' "sea-fish") is a family of snakes characterized by their permanently erect fangs at the front of the mouth. Most elapids are venomous, with the exception of the genus Emydocephalus. Many members of this family exhibit a threat display of rearing upwards while spreading out a neck flap. Elapids are endemic to tropical and subtropical regions around the world, with terrestrial forms in Asia, Australia, Africa, and the Americas and marine forms in the Pacific and Indian Oceans. Members of the family have a wide range of sizes, from the white-lipped snake to the king cobra. Most species have neurotoxic venom which is channeled by their hollow fangs, and some may contain other toxic components in various proportions. The family includes 55 genera with some 360 species and over 170 subspecies. Description Terrestrial elapids look similar to the Colubridae; almost all have long, slender bodies with smooth scales, a ...
