Acanthophis is a genus of elapid snakes. Commonly called death adders, they are native to Australia, New Guinea and nearby islands, and are among the most venomous snakes in the world. Despite their common name, they are not adders at all and belong to the Elapidae family. The name of the genus derives from the Ancient Greek akanthos/ἄκανθος ('spine') and ophis/ὄφις ('snake'), referring to the spine on the death adder's tail.
Taipans are snakes of the genus Oxyuranus in the elapid family. They are large, fast-moving, highly venomous, and endemic to Australia and New Guinea. Three species are recognised, one of which, the coastal taipan, has two subspecies. Taipans are some of the deadliest known snakes.

CSL's product areas include blood plasma derivatives, vaccines, antivenom, and cell culture reagents used in various medical and genetic research and manufacturing applications. The company was established in 1916 as Commonwealth Serum Laboratories and was wholly owned by the Australian federal government until its privatisation in 1994.
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 formally 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 has a slender build and can grow to 2 m (7 ft) in length. The colour of its surface ranges from pale brown to 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, often in farmland and on the outskirts of urban areas, as such places are populated by its main prey, the house mouse. The species is oviparous. The International Union for Conservation of Nature classifies the snake as a least-concern species, though its status in New Guinea is unclear.
Hydrophis belcheri, commonly known as the faint-banded sea snake or Belcher's sea snake, is an extremely venomous species of elapid sea snake. It has a timid temperament and would normally have to be subjected to severe mistreatment before biting. Usually those bitten are fishermen handling nets, although only one-quarter of those bitten are envenomated since the snake rarely injects much of its venom. Although not much is known about the venom of this species, its LD50 toxicity in mice has been determined to be 0.24 mg/kg when delivered intramuscularly.
Venomous snakes are species of the suborder Serpentes that are capable of producing 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 families Elapidae, Viperidae, Atractaspididae, and some of the Colubridae. The toxicity of venom is mainly indicated by murine LD50, 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.
The Australian Reptile Park is located at Somersby on the Central Coast of New South Wales, Australia. It is about 71 kilometres (44 mi) north of Sydney, and is just off the M1 Pacific Motorway, near Gosford. The Park has one of the largest reptile collections in Australia, with close to 50 species on display. The wide variety of reptile species at the Park includes snakes, lizards, turtles, tortoises, tuataras, American alligators and crocodiles.
Taicatoxin (TCX) is a snake toxin that blocks voltage-dependent L-type calcium channels and small conductance Ca2+-activated K+ channels. The name taicatoxin (TAIpan + CAlcium + TOXIN) is derived from its natural source, the taipan snake, the site of its action, calcium channels, and from its function as a toxin. Taicatoxin was isolated from the venom of Australian taipan snake, Oxyuranus scutellatus scutellatus. TCX is a secreted protein, produced in the venom gland of the snake.
Taipoxin is a potent myo- and neurotoxin that was isolated from the venom of the coastal taipan Oxyuranus scutellatus or also known as the common taipan. Taipoxin like many other pre-synaptic neurotoxins are phospholipase A2 (PLA2) toxins, which inhibit/complete block the release of the motor transmitter acetylcholine and lead to death by paralysis of the respiratory muscles (asphyxia). It is the most lethal neurotoxin isolated from any snake venom to date.
Eric Arthur Frederic Worrell (MBE), was an Australian naturalist, herpetologist, science writer and zoo founder and director, known for establishing the Australian Reptile Park at Wyoming on the NSW Central Coast in 1959.
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.
Aipysurus duboisii, also known commonly as Dubois' sea snake and the reef shallows sea snake, is a species of extremely venomous snake in the subfamily Hydrophiinae of the family Elapidae. Its geographic range includes Papua New Guinea, New Caledonia and the northern, eastern and western coastal areas of Australia, that is the Coral Sea, Arafura Sea, Timor Sea and Indian Ocean. It lives at depths up to 80 meters in coral reef flats, sandy and silty sediments which contain seaweed, invertebrates and corals or sponges that can serve as shelter. It preys upon moray eels and various fish that live on the seafloor, up to 110 cm in size. A. duboisii is viviparous, giving birth to live young rather than laying eggs. It displays medium aggressiveness, i.e., will bite if provoked, but not spontaneously. The fangs are 1.8 mm long, which are relatively short for a snake, and the venom yield is 0.43 mg. Aipysurus duboisii is a crepuscular species, meaning that it is most active at dawn and dusk.
The coastal taipan, or common taipan, is a species of highly venomous snake in the family Elapidae. Described by Wilhelm Peters in 1867, the species is native to the coastal regions of northern and eastern Australia and the island of New Guinea. The second-longest venomous snake in Australia, the coastal taipan averages around 2.0 m (6.6 ft) long, with the longest specimens reaching 2.9 m (9.5 ft) in length. It has light olive or reddish-brown upperparts, with paler underparts. The snake is considered to be a least-concern species according to the International Union for Conservation of Nature.
The Papuan black snake is a venomous snake of the family Elapidae native to New Guinea. Reaching around 2 m in length, it is a predominantly black snake coloured grey underneath.
Kevin Clifford Budden was an amateur Australian herpetologist and snake hunter. Budden was the first person to capture a live taipan for research and died from a snakebite in the process of doing so. His work was instrumental in developing a taipan antivenom.
The northern death adder is a species of venomous snake in the family Elapidae.
Jeanette Adelaide Covacevich (1945–2015) was a herpetologist in Queensland, Australia. As a senior curator of vertebrates at the Queensland Museum, she discovered and studied many reptiles and frogs in Queensland. Covacevich is most famous for rediscovering and describing the Inland Taipan snake, the world's most venomous snake. In addition, she described over thirty new species and genera including the Cape York striped blind snake, the Nangur spiny skink, and the Bulburin leaf-tailed gecko.
Ram Chandra was a snake showman in Australia. He was known as Australia's "taipan man" and for his work in extracting snake venom to create antivenoms.
