Top 10 Most Poisonous Snakes on Earth

Poisonous snakes are fascinating and scary at the same time. A snake is classified as poisonous when they’re capable of injecting venom. A snake is poisonous by definition as it harms you via touch or when you eat it. These top ten most poisonous snakes are feared in the countries they live because of their toxic venom that can kill a human rapidly. In this article, we’ll be talking about the lethal dose (LG) measurement. This measurement is the milligrams of toxin per kilo of body mass. For example, a certain type of snake with LD50 will kill 50% of it’s prey on average.

Rattlesnake

Arizona Black Rattler Snake

The rattlesnake stands alone as America’s only snake on this list. At least the rattle on the end of it’s tail offers as a warning to those wandering too close. They are a member of the Pit Viper group of snakes and can strike at 2/3rd of their body length. The Eastern Diamondback is North America’s most venomous species. Juveniles are unable to control how much venom they inject, making them more dangerous than the full grown Diamondback. Nearly all types of rattlesnakes have a hemotoxic venom. If you are bit by one, your tissue will be destroyed and organs will degenerate which causes blood clotting. Even after treatment, it is likely that there will be some scarring at the very least. It’s likely that if someone is bit by a rattlesnake, they will die or lose the limb close to where the bite occurred.  If a rattlesnake bite is untreated, they are more often than not, fatal. If anti venom is administered quickly enough, the death rate is reduced to about 4%.

Death Adder

Death-Adder(1)

Found in Australia and New Guinea, the Death Adder hunts other snakes. Some of the snakes that the Death Adder ambushes are included in our list of most poisonous snakes on earth. They look similar to a Viper with a short body and triangular head. They are capable of injecting between 40mg-100mg of venom with a 40 LD – 50 LD. The bad news is the Death Adder is one of the most dangerous bites in the world as their venom is a neuro toxin. If you’re bit, you’ll become completely paralyzed and within 6 hours, your respiratory system will fail and you die. The symptoms are not immediate which means you should have time to get antivenin which is where the good news comes in. The antivenin is highly successful in treating a Death Adder bite. This snake has the most rapid strike in the world and can go from sitting to strike and back again in 0.13 of a second.

Vipers

Of the 275 odd species of snakes found in India only four are viewed as a real threat to humans.

Vipers are seen all over the world but the most venomous in the family live in parts of Asia such as India and China. The Saw Scaled Viper and Chain Viper are nocturnal and get angry quite quickly. They are often only seen after a heavy rain and are incredibly fast. Their venom often causes symptoms that are right where the bite is such as pain and swelling. Other unsettling symptoms are bleeding from the gums due to a reduction in blood pressure and heart rate. Victims to this bite also experience blistering which can spread throughout the entire limb. Severe pain will be felt for 2-4 weeks. Death may come slowly as septicemia, respiratory or cardiac failure set in anywhere from 1 day to 2 weeks.

Philippine Cobra

Most cobras are venomous but not considered deadly, the Philippine Cobra is an exception. These cobras are able to spit up to three meters which means if you’ve run into one, you’re probably in trouble. The neurotoxic venom prevents your cardio and respiratory system from functioning properly. For those bit by one of these top poisonous snakes, the respiratory system will become paralyzed and death will occur within a half hour. The tissue damage is not major but neurotoxins prevent nerve signals. Symptoms that follow the bite will include vomiting, convulsions and abdominal pain.

Tiger Snake

The south western tiger snake is a medium-large (maximum 1.8 metres) terrestrial elapid confined to the southern part of western W.A.

The neurotoxic venom in the Tiger Snake is extremely potent. This snake which makes Australia home can cause death within 30 minutes of it’s bite. Before an antivenin was found, a Tiger Snake bite had a fatality rate of up to 70%. Symptoms such as pain in the feet or the neck along with sweating are the first things a victim experiences. It becomes hard to breathe and eventually paralysis sets in. A Tiger Snake is non-aggressive so if you leave it alone and don’t accidentally corner it, it will usually leave in peace. If a Tiger Snake should strike, it rarely misses.

Black Mamba

Black Mamba 3

The Black Mamba became known to most of us from the first installment of Kill Bill and is found through much of the African continent. These are the fastest snakes on earth with the ability to move up to 20km/h. They are aggressive and strike with great accuracy with the possibility of striking over and over again. They have the ability to strike a victim up to 12 times with a single bite being poisonous enough to kill between 10-25 adults. The venom, like many other poisonous snakes is a rapid action neurotoxin that has an LD50. It’s capable of delivering an average of 125 mg of venom and up to 400 mg. The victim of a Black Mamba bite will start to feel a tingle all over the body. Vision problem will develop and the mind becomes very confused. You may begin foaming at the most and be unable to control your muscles. Rapid death causing symptoms will set in quickly and medical attention is needed right away. Shock will set in and all of the body’s systems will begin to shut down. Paralysis or a heart attack will occur and eventually you fall into a coma and death. If antivenin is not administered, it is almost 100% guaranteed that death will occur. A victim can even die as quickly as 15 minutes if the bite went straight into the veins.

Taipan

The measurement of a Taipan Snake’s venom is that it’s poisonous enough to kill 12,000 guinea pigs. A resident of Australia, the Taipan’s venom will block arteries due to blodd clotting. It is aggressive and extremely agile, giving it a reputation of being similar to the Black Mamba in many ways.The venom is also very neurotoxic and prior to finding the antivenin formula, nobody had ever survived one of these bites. Death comes quickly, usually within one hour. If a victim does survive, there is often a long period of time in the hospital.

Blue Krait

Bungarus candidus, commonly known as the Malayan krait or blue krait, is one of the species of snakes found in Vietnam.

A snake found in South East Asia and Indonesia, the Blue Krait is the top poisonous snake of it’s species. Even when antivenin is utilized, half of the bites from a Blue Krait cause death. Blue Krait are considered to be cannibals as they are prone to hunting other snakes and even their own species. They awake in the night and are quite shy, preferring not to fight when threatened. Their neurotoxin venom is extremely potent and the symptoms will quickly set in. Muscle paralysis along with cramps and tremors will precede the paralysis. Thankfully, because the Blue Krait is noctural, it’s not often a person has been bit. This is probably a good thing being that before antivenin, there was an 85% fatality rate.

It has an LD50, is ten times more venomous than snakes that are capable of killing an adult human. They are far more common that that of the Cobra. The Inland Taipan isn’t aggressive and humans don’t often run into them. The potential to kill a human within 45 minutes is possible but luckily, there has never been a fatality recorded.
