Pseudonaja
''Pseudonaja'' is a genus of highly venomous elapid snakes native to Australia. Species of this genus are known commonly as brown snakes and are considered to be some of the most dangerous snakes in the world; even young snakes are capable of delivering a fatal envenomation to a human. Despite its common name, the king brown snake (''Pseudechis australis'') is not a brown snake, but a member of the genus ''Pseudechis'', commonly known as black snakes. Species These species and subspecies are recognized: *''Pseudonaja affinis'' Günther, 1872 — dugite or spotted brown snake **''P. a. affinis'' Günther, 1872 — coastal mainland Western Australia **''P. a. exilis'' Storr, 1989 — mainland Western Australia and Rottnest Island **''P. a. tanneri'' ( Worrell, 1961) — mainland Western Australia, Boxer Island, and other islands *'' Pseudonaja aspidorhyncha'' ( F. McCoy, 1879) strap-snouted brown snake — inland eastern Australia *''Pseudonaja guttata'' ( Parker, 1926) — spe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pseudonaja Affinis
The dugite (; ''Pseudonaja affinis'') is a species of venomous, potentially lethal, snake native to Western Australia, a member of the Family (biology), family Elapidae. The word dugite is an anglicisation of names for the snake in some dialects of the Nyungar language, including ''dukayj'' and ''dukitj''. However, another, probably cognate name, ''dobitj'', has become the common name for dugites in Nyungar. (This can cause confusion, because ''dobitj'' is also used in some dialects to refer to other kinds of venomous snakes.) Description The dugite is a venomous snake, considered dangerous. It is coloured grey, green, or brown. The colours vary widely between individuals and are an unreliable means of identifying the species. Black scales can be scattered over the body; their scales are relatively large with a semi-glossy appearance. The most distinguishing characteristic is the head that can be rather small and indistinct from the neck. A dugite's body is long and slender in b ...

Pseudonaja Mengdeni
The western brown snake (''Pseudonaja mengdeni'') is commonly known as Mengden's brown snake, and alternatively, gwardar. ''Pseudnaja mengdeni'' is endemic to Australia. It is highly variable in colour and patterns and is a highly dangerous elapid whose bite can cause severe symptoms resulting in death. It is one of the three species originally classified as '' Pseudonaja nuchalis'' along with '' P. aspidorhyncha'', and ''P. nuchalis''. Taxonomy Previously the western brown snake was considered a ' morph' form of ''Pseudonaja nuchalis'', recent genetic studies have proven it to be genetically unique. It is estimated that ''Pseudonaja nuchalis'' could include in excess of 10 different species. Although currently there have been 8 species chromosomeally identified species these include: ''P. aspidorhyncha'', ''P. mengdeni'', ''P. imperator'', ''P. acutirostris'', ''P. gowi'', ''P. carinata'', ''P. kellyi'' and ''P. nuchalis''.

Pseudonaja Aspidorhyncha
The strap-snouted brown snake (''Pseudonaja aspidorhyncha'') is a species of venomous snake in the family Elapidae. The species is native to South Australia, New South Wales, Queensland, and Victoria. ''P. aspidorhyncha'' is part of a species complex that also includes '' P. mengdeni'' and '' P. nuchalis''; all were formerly included in the latter species. Taxonomy Frederick McCoy described the species in 1879 as the shield-fronted brown snake, distinguishing it from the eastern brown snake (''P. textilis'') by its narrow head, truncated snout and large rostral plate over the back of its head, He noted its similarity to the western brown snake (''P. nuchalis''). Heber Longman described ''Diemenia carinata'' in 1915 from a specimen from Cane Grass Station near Charleville in southwestern Queensland. it was known locally as "tiger snake". Francis J. Mitchell of the South Australian Museum described ''Demansia acutirostris'' from an island in Lake Eyre, noting its depressed snout di ...

Pseudonaja Ingrami
Ingram's brown snake (''Pseudonaja ingrami'') is a species of venomous snake in the family Elapidae. The species is endemic to Australia. Taxonomy Belgian-British zoologist George Albert Boulenger described the species in 1908 as ''Diemenia ingrami'', from a specimen collected on Alexandria Station in the Northern Territory. The specific name, ''ingrami'', is in honour of Collingwood Ingram, who was an English ornithologist and horticulturist. The brown snakes were moved to the genus ''Pseudonaja'' by Australian naturalist Eric Worrell in the early 1960s on the basis of skull morphology, and reinforced by American herpetologist Samuel Booker McDowell in 1967 on the basis of the muscles of the venom glands. This classification has been followed by subsequent authors. Genetic analysis indicates that Ingram's brown snake is a diverged from the ancestor of all other brown snakes except the more basal ringed brown snake (''P. modesta'') and speckled brown snake (''P. guttata'') ...

Pseudonaja Guttata
The speckled brown snake or spotted brown snake (''Pseudonaja guttata'') is a species of venomous Elapidae, elapid snake native to northeastern Australia. Taxonomy English zoologist Hampton Wildman Parker described the speckled brown snake as ''Demansia guttata'' in 1926 from a specimen collected in Winton, Queensland. The brown snakes were moved to ''Pseudonaja'' by Australian naturalist Eric Worrell in the early 1960s on the basis of skull morphology, and reinforced by American herpetologist Samuel Booker McDowell in 1967 on the basis of the muscles of the venom glands. This classification has been followed by subsequent authors. A 2005 analysis using mitochondrial DNA found that the speckled brown snake was an early offshoot of the genus, with the taipans as more distantly related. A 2016 genetic analysis showed that the speckled brown snake was an early offshoot of a lineage giving rise to the taipans, rather than the other brown snakes. Description The speckled brown s ...

Pseudonaja Modesta
The ringed brown snake (''Pseudonaja modesta'') is a species of venomous elapid snake native to a broad swathe of inland Australia, from western New South Wales and Queensland to Western Australia. Albert Günther described it as ''Cacophis modesta'' in 1872, from specimens collected in northwestern Australia. The specific name ''modesta'' is the Latin adjective "unassuming", "orderly", or "well-behaved", regarded as apt by toxicologist Struan Sutherland, as the snake generally does not bite people. Meanwhile, Charles Walter De Vis described ''Brachysoma sutherlandi'' from Carl Creek, Norman River in northwestern Queensland in 1884, and William Macleay described ''Furina ramsayi'', naming it after Edward Pierson Ramsay, in 1885 from a collection from Milparinka in northwestern New South Wales. All three are the same species. Reaching around 50 cm (20 in) in length, the ringed brown snake has grey-brown to red-brown upperparts with a black head and neck split by a crea ...

King Brown Snake
The king brown snake (''Pseudechis australis'') is a species of highly venomous snake of the family Elapidae, native to northern, western, and Central Australia. Despite its common name, it is a member of the genus ''Pseudechis'' (black snakes) and only distantly related to true brown snakes. Its alternative common name is the mulga snake, although it lives in many habitats apart from mulga. First described by English zoologist John Edward Gray in 1842, it is a robust snake up to long. It is variable in appearance, with individuals from northern Australia having tan upper parts, while those from southern Australia are dark brown to blackish. Sometimes, it is seen in a reddish-green texture. The dorsal scales are two-toned, sometimes giving the snake a patterned appearance. Its underside is cream or white, often with orange splotches. The species is oviparous. The snake is considered to be a least-concern species according to the International Union for Conservation of Nature, t ...

Rottnest Island
Rottnest Island ( nys, Wadjemup), often colloquially referred to as "Rotto", is a island off the coast of Western Australia, located west of Fremantle. A sandy, low-lying island formed on a base of aeolianite limestone, Rottnest is an A-class reserve, the highest level of protection afforded to public land. Together with Garden Island, Rottnest Island is a remnant of Pleistocene dune ridges. Along with several other islands, Rottnest became separated from the mainland around 7,000 years ago, when sea levels rose; the traditional Noongar name for the island is ''Wadjemup'', which means "place across the water where the spirits are". Human artefacts have been found on the island dating back at least 30,000 years, but visitation and habitation of the island by the Noongar people appears to have ceased following its separation from the mainland. The island was first documented by Willem de Vlamingh in 1696, who called it t Eylandt 't Rottenest'' ("Rats' Nest Island") after the qu ...

Richard Walter Wells
Richard Walter Wells is an Australian herpetologist. He is known for editing the '' Australian Journal of Herpetology'' in the 1980s, in which he and C. Ross Wellington wrote and published three papers without academic peer review that proposed significant changes to the taxonomy and nomenclature of Australian reptiles and amphibians. In the 2000s, Wells self-published herpetological research in the ''Australian Biodiversity Record''. The scientific names he proposed therein are the subject of a boycott begun in 2013 by some members of the herpetological community. Early life Richard Walter Wells was interested in herpetology in his early teen years when he lived in Prospect, New South Wales. In 1980, he brought several eastern brown snake (''Pseudonaja textilis'') eggs to the offices of ''The Sydney Morning Herald'', where they hatched, an occurrence which Wells stated had never before been captured on film. Career By 1981, after working as a zoological specimen collector with ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Venomous Snake
Venomous snakes are Species (biology), species of the Suborder (biology), suborder Snake, Serpentes that are capable of producing Snake venom, venom, which they use for killing prey, for defense, and to assist with digestion of their prey. The venom is typically delivered by injection using hollow or grooved fangs, although some venomous snakes lack well-developed fangs. Common venomous snakes include the Family (biology), families Elapidae, Viperidae, Atractaspididae, and some of the Colubridae. The toxicity of venom is mainly indicated by murine , while multiple factors are considered to judge the potential danger to humans. Other important factors for risk assessment include the likelihood that a snake will bite, the quantity of venom delivered with the bite, the efficiency of the delivery mechanism, and the location of a bite on the body of the victim. Snake venom may have both neurotoxic and hemotoxic properties. There are about 600 venomous snake species in the world. Evolu ...

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 ...
