Austrelaps Ramsayi
The highland copperhead (''Austrelaps ramsayi''), also known as Ramsay's copperhead, is a species of venomous snake in the family Elapidae endemic to Australia. Taxonomy Gerard Krefft described the highland copperhead in 1864 as ''Hoplocephalus ramsayi'' from a specimen collected in Braidwood, New South Wales. (''Hoplocephalus ramsayi'', new species, pp. 180-181). The specific name, ''ramsayi'', is in honour of Edward Pierson Ramsay, who was an Australian ornithologist and herpetologist,Beolens, Bo; Watkins, Michael; Grayson, Michael (2011). ''The Eponym Dictionary of Reptiles''. Baltimore: Johns Hopkins University Press. xiii + 296 pp. . (''Austrelaps ramsayi'', p. 216). and who collected the holotype specimen. Description ''A. ramsayi'' has an average total length (including tail) of 113 cm (44 inches). It can vary in upper (dorsal) colour from mid to very dark brown, with a creamy yellow belly tinged with red between the differing colours. Distribution and habita ...

Gerard Krefft
Johann Ludwig (Louis) Gerard Krefft (17 February 1830 – 19 February 1881), a talented artist and draughtsman, and the Curator of the Australian Museum for 13 years (1861-1874), was one of Australia's first and most influential zoologists and palaeontologists. According to Macdonald, et al. (2007), Krefft "was among the first to raise the alarm" in relation to "the devastating effects" of the invasive species, such as "sheep, cats, etc., on native species". Also, along with significant others, such as the proprietor of the Melbourne ''Argus'', Edward Wilson, Krefft expressed considerable concern in relation to the effects of the expanding European settlement upon the indigenous population. In addition to his numerous scientific papers, his publications include ''The Snakes of Australia'' (1869), ''Guide to the Australian Fossil Remains in the Australian Museum'' (1870), ''The Mammals of Australia'' (1871), and ''Catalogue of the Minerals and Rocks in the Australian Museum' ...

Holotype
A holotype is a single physical example (or illustration) of an organism, known to have been used when the species (or lower-ranked taxon) was formally described. It is either the single such physical example (or illustration) or one of several examples, but explicitly designated as the holotype. Under the International Code of Zoological Nomenclature (ICZN), a holotype is one of several kinds of name-bearing types. In the International Code of Nomenclature for algae, fungi, and plants (ICN) and ICZN, the definitions of types are similar in intent but not identical in terminology or underlying concept. For example, the holotype for the butterfly '' Plebejus idas longinus'' is a preserved specimen of that subspecies, held by the Museum of Comparative Zoology at Harvard University. In botany, an isotype is a duplicate of the holotype, where holotype and isotypes are often pieces from the same individual plant or samples from the same gathering. A holotype is not necessarily "typ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endemic Fauna Of Australia
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 s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Reptiles Of Victoria (Australia)
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 ...

Austrelaps
''Austrelaps'' is a genus of venomous elapid snakes native to the relatively fertile, temperate, southern and eastern part of the Australian continent. Three species are currently recognized, with no subspecies. They are commonly called copperheads or Australian copperheads. They are not closely related to the American copperhead, ''Agkistrodon contortrix''. Description There are three species of Australian copperheads: the pygmy, the highland, and the lowland. The pygmy copperhead is long, and lives in South Australia and on Kangaroo Island. The highland copperhead is in length and lives in alpine areas of Victoria and New South Wales. The lowland copperhead reaches in length and lives in southern Victoria into Tasmania. Australian copperheads are usually of medium size, , only rarely being more than long, and have a moderate build. Their colour varies a great deal, from a coppery mid-brown to yellowish, reddish, grey or even black, depending on the individual. The copper h ...

Harold Cogger
Harold George "Hal" Cogger (born 4 May 1935) is an Australian herpetologist. He was curator of reptiles and amphibians at the Australian Museum from 1960 to 1975, and Deputy Director of the museum from 1976 to 1995. He has written extensively on Australian herpetology, and was the first author to create a field guide for all Australian frogs and reptiles. Cogger was made an honorary Doctor of Science in 1997.

Ovoviviparity
Ovoviviparity, ovovivipary, ovivipary, or aplacental viviparity is a term used as a "bridging" form of reproduction between egg-laying oviparous and live-bearing viviparous reproduction. Ovoviviparous animals possess embryos that develop inside eggs that remain in the mother's body until they are ready to hatch. The young of some ovoviviparous amphibians, such as ''Limnonectes larvaepartus'', are born as larvae, and undergo further metamorphosis outside the body of the mother. Members of genera ''Nectophrynoides'' and ''Eleutherodactylus'' bear froglets, not only the hatching, but all the most conspicuous metamorphosis, being completed inside the body of the mother before birth. Among insects that depend on opportunistic exploitation of transient food sources, such as many Sarcophagidae and other carrion flies, and species such as many Calliphoridae, that rely on fresh dung, and parasitoids such as tachinid flies that depend on entering the host as soon as possible, the e ...
