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. [2] P. aspidorhyncha is part of a species complex that also includes P. mengdeni and P. nuchalis ; all were formerly included in the latter species. [3]
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). [4] 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". [5] Francis J. Mitchell of the South Australian Museum described Demansia acutirostris from an island in Lake Eyre, noting its depressed snout distinguishing it from other brown snakes. [6]
Australian herpetologist Richard W. Wells divided P. nuchalis into eight species, recognising P. aspidorhyncha, P. carinata and P acutirostris as distinct. [7] These additional species have not been recognized by other authors, [2] and Wells has been strongly criticized for lack of rigour in his research. [8]
For many years, the taxon was regarded as a southern population of a broadly defined P. nuchalis despite the diverse nature of populations included within. The scientific name was resurrected in 2009 as genetic and morphological data confirmed it as a distinct lineage, and it was the oldest binomial name that had been applied to the taxon - hence it had priority. [9]
Generally up to 1.5 metres long, [10] the strap-snouted brown snake is a long thin snake, with no demarcation between its head and neck. The snout has a distinctive chisel shape. [3]
It has light- to medium brown upperparts. [9]
The number and arrangement of scales on a snake's body are a key element of identification to species level. [11] The eastern brown snake has 17 rows of dorsal scales at midbody, 207 to 226 ventral scales, 47 to 63 divided subcaudal scales, and a divided anal scale. Its mouth is lined with six (rarely five) supralabial scales above and seven (rarely eight) sublabial scales below. Its nasal scale is undivided. Its eyes have two postocular scales. [9]
The strap-snouted brown snake is found across central-southern Australia from Hermidale in New South Wales to Penong in South Australia. [9]
The inland taipan, also commonly known as the western taipan, the small-scaled snake or the fierce snake, is a species of extremely venomous snake in the family Elapidae. The species is endemic to semi-arid regions of central east Australia. Aboriginal Australians living in those regions named the snake Dandarabilla. It was first described by Frederick McCoy in 1879 and then by William John Macleay in 1882, but for the next 90 years, it was a mystery to the scientific community; no further specimens were found, and virtually nothing was added to the knowledge of this species until its rediscovery in 1972.
The eastern brown snake, often referred to as the common brown snake, is a species of highly venomous snake in the family Elapidae. The species is native to eastern and central Australia and southern New Guinea. It was first described by André Marie Constant Duméril, Gabriel Bibron, and Auguste Duméril in 1854. The adult eastern brown snake is up to 2 m (7 ft) long with a slender build. Its variable upper parts can be several shades of brown, ranging from pale brown to almost black, while its underside is pale cream-yellow, often with orange or grey splotches. The eastern brown snake is found in most habitats except dense forests. It has become more common in farmland and on the outskirts of urban areas, benefiting from agriculture due to the increased numbers of its main prey, the introduced house mouse. The species is oviparous. The snake is considered to be a least-concern species according to the International Union for Conservation of Nature (IUCN), though its status in New Guinea is unclear.
The red-bellied black snake is a species of venomous snake in the family Elapidae. The species is indigenous to Australia. Originally described by George Shaw in 1794 as a species new to science, it is one of eastern Australia's most commonly encountered snakes. Averaging around 1.25 m in length, it has glossy black upperparts, bright red or orange flanks, and a pink or dull red belly. It is not an aggressive species and generally retreats from encounters with people, but can attack if provoked. Although its venom is capable of causing significant illness, no deaths have been recorded from its bite, which is less venomous than other Australian elapid snakes. The venom contains neurotoxins, myotoxins, and coagulants and has haemolytic properties; victims can also lose their sense of smell.
The woma python, also known commonly as Ramsay's python, the sand python, and simply the woma, is a species of snake in the family Pythonidae. The species is endemic to Australia. Once common throughout Western Australia, it has become critically endangered in some regions.
The dugite is a species of venomous, potentially lethal, snake native to Western Australia, a member of the family Elapidae.
The mud adder, also known as De Vis' banded snake, is a species of venomous snake in the family Elapidae. The species is endemic to certain regions of eastern Australia, including South West Queensland, northern New South Wales and north-west Victoria. Its scientific and common names refer to Charles Walter De Vis (1829-1915), first director of the Queensland Museum and writer of around 50 papers on herpetology.
Pseudonaja is a genus of 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.
The king brown snake 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 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 3.3 m (11 ft) 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, though may have declined with the spread of the cane toad.
The Central Ranges taipan, or Western Desert taipan, is a species of taipan that was described in 2007 by Australian researchers Paul Doughty, Brad Maryan, Stephen Donnellan and Mark Hutchinson. Taipans are large, fast, extremely venomous Australasian snakes. The Central Ranges taipan was named one of the top five new species of 2007 by the International Institute for Species Exploration at Arizona State University.

The species is endemic to eastern Australia and are most commonly found across central inland New South Wales through to the interior of south-eastern Queensland. Common names for this species include grey snake and Dämel's Snake. The specific name, damelii, is in honor of German entomologist Edward Dämel, who collected Australian specimens for Museum Godeffroy.
