No, the fastest-acting venom on Earth belongs to the Australian Box Jellyfish or sea wasp. It's not the most potent venom out there. But encounter one of these guys and you'll be dead in 15 minutes. That's all because of these things They're COVERED with tiny, venom-loaded darts, called nematocysts.
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.
Hemotoxic venom works slower than other types of snake venom, though. That means a person can often survive with proper medical attention. Rattlesnakes, Russell's viper, and copperheads are all snakes with hemotoxic venom.
A king cobra bite can kill a human in 15 minutes and a full-grown elephant in a few hours. What makes these cobras kings is not just their size, or their deadliness — after all, they don't eat humans or elephants — it is that they eat other snakes. Even deadly snakes like kraits or other cobras are prey.
Cobras neurotoxic venom attacks the victim's nervous system and leads to paralysis. Neurotoxic venom is one of the fastest venom to act. It works by attacking the nervous system and stopping the transmission of signals from the nerves to the muscles.
Because boomslang venom is slow-acting, symptoms may not become apparent until many hours after the bite. Although the absence of symptoms provides sufficient time for procuring antivenom, it can also provide victims with false reassurance, leading to their underestimating the seriousness of the bite.
A human can collapse within 45 minutes of a Black Mamba bite. Without treatment it can take 7 to 15 hours for a Black Mamba bite to kill you. The sooner a person is treated after the bite, the better his chances of survival. A Black Mamba antidote is administered where necessary, but some people may be allergic.
The venom of the black mamba snake, one of the world's deadliest poisons administered by one of the world's deadliest reptiles, can kill you within half an hour. Untreated bites have a mortality rate of 100%.
Unarmed Human vs.
The average human is faster than a king cobra on land. A king cobra can slither at about 5 mph over short distances. The average human can walk at 3 mph and run up to 8 mph. Yet, the fastest person alive can run at speeds of 27.5 mph, but only during a sprint.
“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. Do not resort to any local or home remedy because there is only one cure for a snakebite and that is antivenom.”
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.
The blue-ringed octopus is one of the world's most venomous sea creatures. Even more impressive, Australia is home to 20 of the 25 most venomous snakes in the world, including all of the top 11.
The most poisonous animal in the world lives off the coast of Australia: the box jellyfish. This jellyfish - also known as cube jellyfish or stinger - has 15 long tentacles that are full of deadly poison.
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.
Over distance they slow down to 7 MPH (12 KPH). However, the average human run speed over distance is 6 MPH (10 KPH). Thus, you cant outrun a Black Mamba. Still, Black Mambas are extremely shy and will do everything they can to avoid people.
Mongooses are noted for their audacious attacks on highly venomous snakes, such as king cobras. The Mongoose is a snake killer by nature. These small mammals have some immunity to cobra venom, so they are one of the most successful animals that hunt cobras. They need more than good defense to kill a cobra, though.
Before we get to the fun bit, we should note that black mambas are from Africa and inland taipans are from Australia. This means under natural circumstances, the two species would never meet.
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.
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.
The mortality rate is high in untreated cases: Dangerousness of bite - severe envenomation likely, high lethality potential. Rate of envenoming - >80% Untreated lethality rate - >80%
Predation. Adult mambas have few natural predators aside from birds of prey. Brown snake eagles are verified predators of adult black mambas, of up to at least 2.7 m (8 ft 10 in). Other eagles known to hunt or at least consume grown black mambas include tawny eagles and martial eagles.
