seudonaja is a genus of venomous elapid snakes native to Australia. Members are known commonly as brown snakes and are considered to be one of the most dangerous snakes in the country; even young snakes are capable of delivering a fatal envenomation to a human. Brown snakes are easily alarmed and may bite if approached closely, handled or threatened. Less than half of bites contain venom, and there are minimal effects at the bite site. Sudden, early collapse is often a feature of brown snake envenomation. A prominent effect of envenomation is venom-induced consumption coagulopathy and this can lead to death. Renal damage may also rarely occur. Other clinical signs include: abdominal pain, breathing and swallowing difficulty, convulsions, ptosis, hemolysis, hypotension from depression of myocardial contractility, renal failure. Notably rhabdomyolysis is not a feature of envenomation by brown snakes. - Read more ..
9. Death Adder
Acanthophis is a genus of highly venomous 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. The name of the genus derives from the Ancient Greek acanthos/ἄκανθος "spine" and ophis/ὄφις "snake", referring to the spine on the death adder's tail. Seven species are listed by ITIS, though it remains unclear how many species this genus includes, with figures ranging from 4 to 15 species being quoted. A bite from a death adder causes paralysis. While this paralysis is very minor at first, it can cause death from a complete respiratory shutdown in as little as six hours. Symptoms peak in 24–48 hours. Symptoms of envenomation can be reversed through the use of death adder antivenom, or using anticholinesterases, which break the synaptic blockade by making acetylcholine more available to the parasympathetic nervous system, thus mitigating the effects of the venom. Before antivenom was introduced, more than 50% of death adder bites were fatal. Now, with the antivenom, and due to the slow progression of envenomation symptoms, fatalities from death adder bites are very rare in Australia. In New Guinea, deaths from these snakes are still common. -Read more ..
8. Giant Black Tiger Snake
Tiger snakes are a type of venomous serpent found in southern regions of Australia, including its coastal islands and Tasmania. These snakes are highly variable in their colour, often banded like those on a tiger, and forms in their regional occurrences. All populations are in the genus Notechis, and their diverse characters have been described in further subdivisions of this group. Tiger snakes possess a potent neurotoxin (notexin), coagulants, haemolysins and myotoxins, and rank amongst the deadliest snakes in the world. Symptoms of a bite include localized pain in the foot and neck region, tingling, numbness, and sweating, followed by a fairly rapid onset of breathing difficulties and paralysis. While antivenom is effective, mortality rate for this species is over 60% if not treated. Treatment is the same for all deadly Australian snakes. The Pressure Immobilization Method (PIM) is used to inhibit the flow of venom through the lymphatic system. Broad thick bandages are applied over the bite, then down and back along the limb to the armpit or groin. The affected limb is then immobilized with a splint. Identification of the venom is possible if traces are left near the wound. You do not need to identify the snake if bitten in Tasmania, however, as the same antivenom is used to treat all Tasmanian snakes' bites. The availability of antivenom has greatly reduced the incidence of fatal tiger snake bites. -Read more ..
7. Western Tiger Snake
Tiger snakes are a type of venomous serpent found in southern regions of Australia, including its coastal islands and Tasmania. These snakes are highly variable in their colour, often banded like those on a tiger, and forms in their regional occurrences. All populations are in the genus Notechis, and their diverse characters have been described in further subdivisions of this group. Tiger snakes possess a potent neurotoxin (notexin), coagulants, haemolysins and myotoxins, and rank amongst the deadliest snakes in the world. Symptoms of a bite include localized pain in the foot and neck region, tingling, numbness, and sweating, followed by a fairly rapid onset of breathing difficulties and paralysis. While antivenom is effective, mortality rate for this species is over 60% if not treated. -Read more ..
6. Beaked Sea Snake
Beaked seasnake (Enhydrina schistosa, also known as the hook-nosed sea snake, the common sea snake, and the Valakadyn sea snake ) is a species of sea snake. These snakes are generally found in the coast and coastal islands of India. They are amongst the most common of the 20 kinds of sea snakes found in that region. They are active both during the day and at night. They are able to dive up to 100 m and stay underwater for a maximum of five hours before resurfacing. Seasnakes are equipped with glands to eliminate excess salt. They are venomous and notably aggressive, with some herpetologists describing them as "cantankerous and savage" (Heatwole 1999, p.121). The venom of this snake is rated four to eight times as toxic as cobra venom. About 1.5 milligrams of its venom is estimated to be lethal. -Read more ..

3. Taipan
The taipans are a genus of large, fast, highly venomous Australasian snakes. The coastal taipan (Oxyuranus scutellatus) is the third most venomous land snake in the world and arguably the largest venomous snake in Australia. Its venom contains taicatoxin, a highly potent neurotoxin. The danger posed by the coastal taipan was brought to Australian public awareness in 1950, when young herpetologist Kevin Budden was fatally bitten in capturing the first specimen available for antivenom research. The coastal taipan is often considered to be one of the deadliest species in the world. -Read more ..
2. Common Brown
Pseudechis australis, the common King Brown or Mulga snake, is a highly dangerous species of snake found in Australia. It is one of the largest venomous snakes in the world, the second largest in Australia, and capable of producing large amounts of venom. Despite one of its common names, King Brown, it is part of the Pseudechis (black snake) genus. Mulga snake venom by world standards is very toxic and is produced in large quantities. The average tiger snake produces around 10–20 mg when milked. By comparison, a larger mulga snake may deliver over 150 mg in one bite. The LD50 is 2.38 subcutaneous. Black snake anti-venom is used to treat bites from this species, after a CSL Venom Detection Kit has returned a conclusive result for mulga snake envenomation and there are signs that anti-venom usage is required. -Read more ..
1. Fierce Snake
The Inland Taipan (Oxyuranus microlepidotus), also known as the Small Scaled Snake or Fierce Snake, is native to Australia and is the most venomous land snake on Earth. It is a species of Taipan belonging to the Elapidae family. Although highly venomous, it is very shy and secretive, preferring to escape from trouble, biting only if threatened. The average venom yield is 44 mg, 110 mg being the largest recorded, and the venom has a mouse LD50 of 0.03 mg/kg. Its venom is 200-400 times more toxic than most rattlesnakes and 50 times as toxic as a cobra. The Inland Taipan has neurotoxic venom that could potentially kill an adult human in 45 minutes. There have been no documented human fatalities; bites were treated using antivenom. As of late 2003, all bites positively identified as having been caused by the Inland Taipan have occurred in herpetologists handling the snake, although there are many case reports of bites likely caused by the species. -Read more ..
