Twenty minutes after being bitten you may be lose the ability to talk. After one hour you're probably comatose, and by six hours, without an antidote, you are dead. A person will experience "pain, paralysis and then death within six hours," says Damaris Rotich, the curator for the snake park in Nairobi.
I felt a terrible burning, like pins and needles, in my leg. It felt like my blood was boiling. The pain was radiating up my leg; I was battling to breathe and started feeling weak," she said.
The killer of the most people
The saw-scaled viper (Echis carinatus) may be the deadliest of all snakes, since scientists believe it to be responsible for more human deaths than all other snake species combined.
Rule Number 1: Don't Try To Outrun A Snake
Not because your kid can't — they probably could! The very fastest snake, the Black Mamba, can slither at about 12 MPH, and a truly scared human (even one with short legs) could probably exceed that.
The inland or western taipan, Oxyuranus microlepidotus, is the most venomous snake in the world, according to Britannica. Native to Australia, this snake has the deadliest venom based on median lethal dose, or LD50, tests on mice.
The black mamba, for example, injects up to 12 times the lethal dose for humans in each bite and may bite as many as 12 times in a single attack. This mamba has the fastest-acting venom of any snake, but humans are much larger than its usual prey so it still takes 20 minutes for you to die.
Stories of black mambas that chase and attack humans are common, but in fact the snakes generally avoid contact with humans. Most apparent cases of pursuit probably are examples of where witnesses have mistaken the snake's attempt to retreat to its lair when a human happens to be in the way.
There are no free roaming black mambas in Australia.
The bite of a black mamba can cause collapse in humans within 45 minutes. Without appropriate antivenom treatment, symptoms typically progress to respiratory failure, which leads to cardiovascular collapse and death. This typically occurs in 7 to 15 hours.
Black Mambas are described as one of the fastest and most venomous snakes in the world, a great combination for a predatory snake, not a good combination for a pet.
Introducing the most venomous snake in the world and epic predator of the Australian outback! The inland taipan is otherwise known as the fierce snake or small scaled snake. They can be marvelled at in our Robert's Reptile House, right here at Australia Zoo.
The Eastern brown snake (Pseudonaja textilis) has a venom LD 50 value of 0.053 mg SC (Brown, 1973) and a value of 0.0365 mg SC (Ernst and Zug et al. 1996). According to both studies, it is the second most venomous snake in the world.
The king cobra, which does prey on cobras, is said to be immune to their venom.
The “Big 4” snakes are currently Russell's viper, common krait, Indian cobra, and Indian saw-scaled viper. Russell's vipers are considered the deadliest because they bite the most people. About 43% of all medically significant snakebites in India came from this snake.
Inland taipan (Oxyuranus microlepidotus)
The most venomous snake in the world is considered to be the inland taipan, endemic to central-eastern Australia. It has by far the highest median lethal dose of venom of any snake, and indeed probably any animal, making it the most toxic.
And it's easy to believe they're right. After all, there's a 37-year-old list that says that 21 of the 25 most toxic snakes in the world are all from Australia.
A king cobra would win a fight against a taipan. The taipan has much deadlier venom, but that's not going to save it against the great amount of experience that king cobras have in attacking snakes. Neither snake lives in the same area of the world and they're from different families.
Animals that are born with two or more heads have a condition called polycephaly, which is more common in reptiles than in mammals. The unique snake is now safely in professional care. An extremely rare snake with two heads has been found in the wild in South Africa.
Australian Box Jellyfish
The box jellyfish is the world's most venomous animal with four species — Chironex fleckeri, Carukia barnesi, Malo kingi, and Chironex yamaguchii — considered highly venomous. The Chironex fleckeri, also known as the Australian box jellyfish is considered the most venomous animal in the world.
It's rare for Australian snakes to strike. It's even more uncommon for the fangs to penetrate clothing and the skin.
"Including the brown, tiger, black, taipan, death adder and certain sea snakes and all these snakes are found in Queensland," Mr Farry said. "Most Australian snake bites are associated with minimal local pain and bite marks can be easily missed."
Mongooses have mutated cells that block the mambas' neurotoxins from entering their bloodstream. This makes them capable of surviving the venomous snake's deadly bite. (See how a mongoose fends off a lion.)
The Black Mamba is estimated to be worth a whopping $220 million.
