Without any doubt Inland Taipan is the world’s most poisonous snake. Its bite can kill anyone within hours. Without prompt medical assistance its victim has rarest chance of recovery.
Generally Taipans are uniformly olive or dark brown, the head is somewhat darker brown.Average Taipan’s length is 1.8 meters and maximum of 3.7 meters and are mostly found in Northern Australia and Southern New Guinea.Some species are also found in Central Australia and New Guinea.
Taipans are divided into following five sub-species viz; Western or Inland Taipan (Oxyuranus Microlepidotus) or (Fierce Snake), Papuan Taipan (Oxyuranus S. Canni), Common or Coastal Taipan (Oxyuranus Scutellatus), Central Ranges Taipan (Oxyuranus Temporalis) and North-West Australian Taipan (Oxyuranus Scutellatus Barringeri). Here Inland Taipan (Fierce snake) is the most toxic of all. Maximum yield recorded from a single bite of Inland Taipan is 110mg. Just few mg of Inland Taipan’s venom is enough to kill over 100 people or 250,000 mice. Australia’s Western or Inland Taipan or Fierce Snake is the world’s most toxic terrestrial snake.
Philippine Cobra is second deadliest snake in our list.Smaller in size this snake is one of the most poisonous in the world. Its venom is a neurotoxin which affects cardiac and respiratory function and can cause neurotoxicity and respiratory paralysis and death in hardly 30 minutes. The bite causes only minimal tissue damage. The Philippine cobra is capable of spitting their venom up to three meters.
Its average length is usually up to 100 centimeters and it can understand and react to visual clues.it is mostly found on the islands of Luzon, Mindoro, Catanduanes and Masbate.
The snake feeds predominantly on small mammals. Rodents are preferred diet however they also feed on frogs, lizards, small birds and eggs.
Indian Krait is third in our list of World’s most Venomous snakes.It has enlarged hexagonal vertebral scales and there are narrow white crossbars on the back more or less distinct in pairs. Its scales are shiny. Its neck is not evident and its iris is black. Its body is long and cylindrical and its tail is one-sixth to one-eleventh of its total length. It is lustrous black or bluish black above with paired narrow white crossbars indistinct or absent anteriorly. In the young ones the cross bars are conspicuous.
Their venom is 16 times more effective 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 neuron endings to properly release the chemical that sends the message to the next neuron. 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.
They are mostly found in India,Srilanka and Pakistan.
Up to 22 feet in length king cobra is world’s longest poisonous snake. It is mostly found in the forests of south East Asia and India. The average lifespan of this massively bulky headed giant is 20 years.
Cobra uses other smaller snakes, lizards and birds as its diet. It senses it’s pray by receiving smell through its tongue. Cobra is well capable of killing a human by just single bite.
This dude appears to have a high degree of intelligence. It avoids attacking another venomous snake for fear of being bitten. It feeds exclusively on harmless species of other snakes.
The female King Cobra builds a nest then deposits her eggs. Lying close by, she guards the nest and is highly aggressive toward anything that closely approaches the nest.
Black Mamba is fifth in our list of world’s most dangerous snakes.It is the longest venomous snake in Africa, averaging around 2.5 meters (8.2 ft), and sometimes growing up to 4.3 meters (14 ft).
Its name is derived from the black coloration inside the mouth.Mamba uses its incredible speed to escape threats, not to hunt prey. It is known to be capable of reaching speeds of around 20 kilometers per hour (12 mph), traveling with up to a third of its body raised off the ground. Over long distances the black mamba travels 11 to 19 kilometers per hour (6.8 to 12 mph), but in short bursts it can reach a speed of 23 kilometers per hour (14 mph), making it the fastest land snake.
Black Mambas are found in African savannas and open woodlands.
