Amaizing Animal Facts: Deadliest Snakes in the World Pictures and Facts

There are various snakes in the world and most of these snakes are very poisonous. Many scientists are now studying their behaviour and extracting venom from them in a purpose of getting cure against snake bites and on how to tame them and to understand their habitat. Among all the known snakes in the world their are a few that top the list as the most deadliest snakes in the world, they may look nice and friendly but their bite surely will put you down in serious condition.

List of Deadliest Snakes in the world as per their ranking

1. The Inland Taipan (Oxyuranus microlepidotus), also known as the Small Scaled Snake and Fierce Snake, is a highly venomous snake that lives in Australia, notorious for having the most potent venom of any species of snake in the world.The Fierce Snake or Inland Taipan is a species of Taipan belonging to the Elapidae family.
Classification:
Kingdom: Animalia
Phylum: Chordata
Class: Reptilia
Order: Squamata
Suborder: Serpentes
Family: Elapidae
Genus: Oxyuranus
Species: O. microlepidotus

Venom

A single bite from the Inland Taipan contains enough venom to kill as many as 100 human adults, or 250,000 mice. The average venom yield of this snake is 44 mg, with a 110-mg being the largest recorded yield. Its venom is 50 times more toxic than that of the Indian Cobra and 650 - 850 times more toxic than that of a Western- or Eastern Diamondback. The Inland Taipan has an extremely neurotoxic venom which can cause death to a adult human in as little as 45 minutes. Although highly venomous it is a relatively timid snake provided that it is left alone. Even so, if it is suspected that a bite from this snake has occurred, medical attention should be sought immediately. Although known as the most venomous land snake in the world, there have been no documented human fatalities. All known bites have been treated using antivenom.

2. Pseudonaja textilis (Eastern or Common brown snake)
Bites from Pseudonaja affinis (Dugite) most often produces coagulopathy, with other clinical signs including:, abdominal pain, breathing and swallowing difficulty, convulsions, ptosis, hemolysis, hypotension from depression of myocardial contractility, renal failure or rhabdomyolysis. The specific procoagulant involved is a serine protease with a sialic acid component which also contributes to the coagulant action that has a different specific activity than the procoagulants from P. inframacula, P. nuchalis, and P. textilis but has a homologous primary structure.
The ringed-brown snake P. modesta has been reported to cause systemic envenomation but, in contrast with other, more toxic members of the genera, there was a clinical absence of coagulopathy or paralysis with general symptoms being mild.
In direct contrast, P. nuchalis (Gwardar) is an acutely venomous snake capable of causing coagulopathy, hypotension from myocardial damage and renal failure but without neurotoxic symptoms. As previously discussed, the procoagulant is a serine proteases with a sialic acid component, which also contributes to the coagulant action, that has a specific bioactivity but shares sequential homology.
Pseudonaja textilis (Eastern brown snake) is the most toxic member of the genera and, at 12 times the toxicity of the Indian cobra Naja naja, it is the second most toxic land snake in Australia. However, due to the greater range, occurrence in urban areas and aggressive temperament, the eastern brown snake is the most dangerous and clinically important snake in Australia. The venom of the Eastern Brown snake is slow to produce effect, but once symptoms emerge they proceed with terrifying rapidity with death being sudden and unexpected. Part of the problem is that the early signs of the bite pathology closely resemble that of the occurrence of psychological shock and thus may be misdiagnosed. Symptomology of envenomation include: cardiorespiratory failure, disseminated intravascular coagulation accompanied by very active secondary fibrinolysis which contributes to the acute bleeding, renal failure, and severe thrombocytopenia. The coagulant component of the venom is a powerful complete prothrombinase that makes up over 30% of the total venom protein and converts prothrombin to alpha-thrombin which ultimately results in the clinically seen disappearance of fibrinogen and accompanying rise in fibrin in the blood.Bites are treated with brown snake antivenom.

Venom
The Eastern Brown Snake is the second most venomous land snake in the world after the Inland Taipan. Although Eastern Browns will seek to avoid a confrontation, it has a very toxic venom, and when bitten can cause death. Sub-adults have been known to cause fatalities in humans. The venom contains both neurotoxins and blood coagulants.

3. Bungarus is a genus of venomous elapid snakes found in India and South-East Asia. Commonly referred to as kraits, there are 12 species and 5 subspecies.
Classification:
Kingdom: Animalia
Phylum: Chordata
Subphylum: Vertebrata
Class: Reptilia
Order: Squamata
Suborder: Serpentes
Family: Elapidae
Genus: Bungarus
Daudin, 1803

Venom

Bungarus species contain neurotoxic venom that is 16 times more potent than cobra venom. Krait venom is extremely powerful and quickly induces muscle paralysis. Clinically, their venom contains mostly pre-synaptic neurotoxins. These affect the ability of nerve endings to properly release the chemical that sends the message to the next nerve. Following envenomation with bungarotoxins, transmitter release is initially blocked (leading to a brief paralysis), followed by a period of massive overexcitation (cramps, tremors, spasms), which finally tails off to paralysis. Not all these phases may be seen in all parts of the body at the same time. Fortunately, since kraits are nocturnal they seldom encounter humans during daylight hours so bites are rare. Nonetheless, any bite from a krait is potentially life-threatening and must therefore be regarded as a medical emergency. Note that there is frequently little or no pain at the site of a krait bite and this can provide false reassurance to the victim. Typically, victims start to complain later of severe abdominal cramps accompanied by progressive muscular paralysis, frequently starting with ptosis. As there are no local symptoms, a patient should be carefully observed for tell-tale signs of paralysis (eg the onset of ptosis, diplopia and dysphagia) and treated urgently with antivenom. Before antivenom was developed, there was an 85% mortality rate among bite victims.Krait antivenom is often ineffective and as a result, mortality rate is at 50% even with treatment. Because of this, it is sometimes arguably considered the world's most dangerous snake. Note that it is also possible to support bite victims via mechanical ventilation, using equipment of the type generally available at hospitals. Such support should be provided until the venom is metabolised and the victim can breathe unaided. If death occurs it takes place approximately 6 to 12 hours after the krait bite. Cause of death is respiratory failure ie suffocation via complete paralysis of the diaphragm.

4.Taipans are large (up to 3 metres in length), fast, highly venomous Australian snakes, one of which, the Fierce Snake, has the most toxic venom of any land species worldwide, although it is not the most deadly. The taipan was named by Donald Thompson after the word used by the Wik-Mungkan Aboriginal people of central Cape York Peninsula, Queensland, Australia.
There are three known species: the common taipan, the less common inland taipan (also known as the Fierce Snake and small-scaled snake) (Oxyuranus microlepidotus) and a recently discovered third species. The common taipan has two subspecies: the mainland coastal taipan (Oxyuranus scutellatus scutellatus) and the Papuan taipan (Oxyuranus scutellatus canni) native to the southern coast of Papua New Guinea. Their diet consists primarily of small rodents, especially rats, and bandicoots.

Genus: Oxyuranus

Venom and toxicity

The inland taipan is often considered to be the most venomous land snake. With an LD50 of 0.025 mg/kg, it is 20 times as venomous as a common cobra. Lethal dose calculations are made on mice, so they have a murine bias. The bias is emphasised in this species of snake, as it is specialised to feed on rodents. Calculated LD50 values might not be applicable to non-mammalian species, and may even be inaccurate for mammals other than mice and other rodents. The venom from a single bite of the inland taipan might be potent enough to kill about 250,000 mice, or the mass-equivalent of 100 men. This species generally lives in remote and sparsely inhabited areas. Like most snakes, inland taipans are generally shy and will usually not bite unless they feel threatened. No fatalities have been attributed to this species, and all known bites have been to people who keep them in captivity or actively seek them out in the wild.
The common taipan is the third-most venomous snake on Earth 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 common taipan is often considered to be one of the deadliest species in the world. Mortality rate without treatment is second only to the black mamba, nearing 100%. However, antivenom treatment is highly effective. In several aspects of morphology, ecology and behaviour, the common taipan is strongly convergent with an African elapid, Dendroaspis polylepis (the black mamba).

Tiger snakes are usually black in Tasmania and the colour and width of the bands can vary. This specimen can be seen at the Reptile Centre at Gunns Plains.

5. Tiger Snake
The Tasmanian Tiger Snake has recently been shown to be the the same species as that which occurs on the south-eastern Australian mainland, (Notechis scutatus). The markings are extremely variable and should not be used in isolation to identify snakes. Colours range from jet black, through yellow/orange with grey bands to sandy grey with no bands. There are unconfirmed reports of red-bellied Tiger snakes in north-east Tasmania. Typical forms are of a black snake with either no bands or faint yellow to cream bands. Dark olive snakes with yellow bands are fairly common.
Generally the belly is pale yellow, white or grey, the enlarged ventral scales often edged with black. The head is broad and blunt. It can be difficult to distinguish the Tiger Snake from the Copperhead since sizes, habitat preferences and behaviour overlap somewhat. Tiger Snakes have 13 - 19 rows of scales around the middle of the body, the usual number being 17. On the mainland of Tasmania Tiger snakes reach a length of 1 to 1.8 m. The Chappell Island population reaches prodigious lengths -- up to 2.1 m. Male tiger snakes reach a greater size than females and have larger heads.
Threats:Now legally protected in Tasmania, Tiger snakes still face great danger from human activities such as destruction and fragmentation of habitat. Many are needlessly killed on the road when deliberately run over.
Fangs and poison: The highly toxic venom is produced in large amounts. The venom is mainly neurotoxic, affecting the central nervous system, but also causes muscle damage and affects blood clotting. The breakdown of muscle tissue can lead to kidney failure. I

6. 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.
It is found in the Arabian Sea and Persian Gulf (off Oman), south of the Seychelles and Madagascar, the seas off South Asia (Pakistan, India and Bangladesh), Southeast Asia (Myanmar (formerly Burma), Thailand, Vietnam), and Australia (Northern Territory and Queensland) and New Guinea.

Habitat & habits

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, but not aggressive and are thus handled by the fishermen without fear, though they are thrown back into the sea upon sight. 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.
The principal food is fish. The snake is also eaten as meat by Hong Kong and Singapore fishermen and locals alike
