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 saw-scaled viper, Echis carinatus, is considered the deadliest snake in the world, according to Britannica. This type of snake is said to be responsible for "more human deaths than all other snake species combined." The venom of the saw-scaled viper is not as lethal as other snakes, but it is far more aggressive.
Australian Brown Snake
Its venom is reputed to be the second most toxic in the world. They cause the most snakebite deaths in Australia - 1/14,000 of an ounce of this venom is enough to kill a person.
3. Coastal Taipan. The coastal taipan is found in coastal regions of Northern and Eastern Australia and the nearby island of New Guinea. It produces venom that is almost identical to that of the inland taipan – considered to be the most venomous snake in the world.
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 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.
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.
A new study suggests that king snakes are, pound for pound, the strongest constrictors in the world.
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.
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.
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.
Unfortunately, in the end, the python's power was no match for the cobra's venom. “It would kill the python pretty quickly,” Sheehy says. “Probably within 30 minutes, they could both be dead.”
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.

Except no one told the kingsnake. Kingsnakes squeeze their prey to death, are immune to rattlesnake venom and are so named for their astonishing ability to overpower and eat snakes that are much larger than they are.
Their most remarkable type of prey, however, is other snakes! California Kingsnakes are “kings” because they hunt and devour various snake species, including other kingsnakes and even rattlesnakes – they are immune to rattlesnake venom!
It is no doubt that king cobras do occasionally consume large prey such as monitor lizards or even pythons. One cannot but wonder how the snake is able to make dynamic decisions and evaluate the risks and gains of pursuing prey such as a rock python, which can potentially kill the cobra by constricting it.
The only known species is Titanoboa cerrejonensis, the largest snake ever discovered, which supplanted the previous record holder, Gigantophis garstini.
The blue-ringed octopodes (Hapalochlaena spp.) produce tetrodotoxin, which is extremely toxic to even the healthiest adult humans, though the number of actual fatalities they have caused is far lower than the number caused by spiders and snakes, with which human contact is more common.
An unlikely tale, perhaps—yet Ireland is unusual for its absence of native snakes. It's one of only a handful of places worldwide—including New Zealand, Iceland, Greenland, and Antarctica—where Indiana Jones and other snake-averse humans can visit without fear.
"For poisonous snakes like cobras and rattlesnakes, biting is one of the reflexes that can be activated in the brain even hours after the animal dies," Beaupre added.
The reticulated python, the longest living species of snake in the world, are constrictors, meaning they coil around their prey and squeeze them until they're dead in just a couple minutes.
"Most snakebites, even cobra bites, are not fatal." Whitaker said. "But any snakebite must be treated as a medical emergency. "The single most important thing to do is to get to a hospital without any delay.
