There are nearly 3,600 species of snakes. Apart from the two poles and Ireland, they can be found all over the world. Men have learned to be wary of these animals. We can separate these species into two large groups: Venomous and non-venomous snakes.

In this article,we have ranked the 10 most venomous snakes in the world, and therefore, which can be dangerous for humans.

Among these snakes, there are some very aggressive species and others more fearful.

10. Tiger Snake

Tiger Snake

The Tiger Snake is a species of venomous snake of the Elapidae family found in Australia. Like the Cobra, this reptile is very aggressive.

Its venom composed of neurotoxins, myotoxins and hemolysins makes it a very powerful poison responsible for nearly 20% of bites in Australia.

Symptoms are tingling in the limbs, numbness, abnormal sweating, breathing difficulties and even paralysis.

It is best to treat this bite if you are attacked by a Tiger Snake, as nearly 60% of untreated bites have resulted in death.

9. Russell’s Viper

Russell's Viper

The Russell’s Viper is an extremly deadly snake in Asia. A bite from the Russell’s Viper can have a devastating effect on human blood. Yes, a single drop of its venom mixed with blood can turn it into a thick jelly in less than 30 seconds. It is part of the famous “Big Four“, the 4 snakes responsible for the highest number of bites in India.

The effects of the Russell’s Viper venom are as follows:

  • Local pain
  • Blisters
  • Vomiting
  • Kidney failure
  • Necrosis
  • Drop in blood pressure
  • Heavy bleeding

Others also suffer additional effects that may appear within 4 weeks after the bite, such as infertility, loss of hair and softening of body curves in women. In other words, a return to prepuberty.

Thousands of people have died from the bite of this snake. If this species is so deadly, it is because it is constantly in contact with Man. Indeed, feeding mainly on small rodents, this one is often found in the plains, near farmers. It is present in Bangladesh, Sri Lanka, and Pakistan.

Despite its toxicity, this snake remains a magnificent specimen. Make this reptile a daily companion by wearing a beautiful Viper Ring.

8. Eastern Brown Snake

Found all along the coast of Australia, from northern Queensland through New South Wales to South Australia, the Eastern Brown Snake is responsible for more than 60% of snakebite deaths on the Australian continent.

An adult of this species can reach up to 6.5ft (2m) and is known to be a fast and very aggressive reptile. It is this behavior that made us place this snake in our top 10.

Like the Cobra, the Eastern Brown Snake lifts one third of its body off the ground when it feels in danger, representing an “S” shape.

The poison of the Eastern Brown Snake is among the most powerful in the world. In fact, a single dose of its venom is powerful enough to kill up to 80 men.

Its effects are quite numerous, the main one being a progressive paralysis and the prevention of blood clotting. To counteract it, several doses of antivenom will be necessary.

  • Other symptoms can be :
  • Heavy bleeding
  • Drop in blood pressure
  • Kidney and heart failure
  • Vomiting

If you haven’t seen it yet, I suggest you watch this video of a woman who found an Eastern Brown Snake … under her fridge. This reptile had simply found this interesting place to nest. Lucky for her to have spotted its head sticking out of the fridge 😰

7. Fer-de-Lance

We are now on the side of Costa Rica, home to the Fer-de-Lance, an extremely dangerous snake. Belonging to the Viperidae family, this snake is responsible for many snakebites in Central America.

It can reach a size of 8ft (2.50m), although its average size is around 6ft (1.80m). Like many species, the female is bigger than the male. Its natural coloring allows it to blend in easily in trees or in water. It is easily recognizable thanks to its triangular head.

Fer-De-Lance Snake

If the Fer-de-Lance is part of our Top 10, it is because it is capable of injecting a very large quantity of venom in a single bite. Its poison can cause severe necrosis and death if not treated quickly.

But then, is it dangerous to go on vacation in Costa Rica knowing that the Fer-de-Lance is responsible for nearly 50% of the bites in Costa Rica ?

Well, don’t worry ! Despite its reputation, you have little chance of crossing paths with this venomous snake. In fact, most accidents occur among farmers and ranchers, as it likes to roam in the countryside and in rural and remote areas.

6. Puff Adder

Puff Addeer

The Puff Adder is one of the fastest attacking snakes (2.6m/s). This species lives on the African continent and is considered one of the most dangerous in the world. However, this reptile is not a real danger for humans because it perceives it more as a predator than a prey, preferring to flee if it feels threatened.

This nocturnal animal is very present in Africa. It can be seen all over the continent and up to 6560ft (2,000m). The only place where it does not like to live is in tropical rainforests. Specimens are also present in Yemen, Oman and Saudi Arabia and Morocco.

Its venom is composed of a cytotoxic substance, which means that it gradually destroys cells. Only 100mg of its poison can kill an adult male in 24 hours. Fortunately, the Puff Adder never injects such a quantity in a bite, but this does not prevent it from being very dangerous.

Depending on the area infected, the venom can cause swelling, bleeding, bruising, and even necrosis if the bite is not treated quickly.

These symptoms can also be accompanied by severe pain, vomiting, nausea and the risk of fainting.

Normally, the Puff Adder is a slow, placid animal that uses its camouflage to keep a low profile. It spends most of its time on the ground, but is also capable of swimming and perching on bushes for warmth.

Contrary to what one might think, the Puff Adder only attacks humans if it has no choice because it feels threatened or in danger. Its advantage: it “warns” you of its intention to attack by emitting a whistle and by making movements with its head. This gives you just enough time to run 😅 As we said before, this snake perceives Man as a predator. So, if you fall in front of this animal, leave it alone and it will not harm you.

5. Cobra

Cobra Snake

Among the Cobras, there are two species that may be among the 10 most venomous snakes in the world: the King Cobra and the Philippine Cobra.

The King Cobra is considered the longest venomous snake in the world, with a size of up to 18ft (5.5m).

The Philippine Cobra averages only 3ft (1m), and 5ft (1.5m) for the largest specimens.

The Cobra does not have the most toxic venom in the world. The toxicity of this snake is due to the amount of venom it is able to inject in one bite. Indeed, a single dose of its venom can be up to 500mg, which is enough to kill an animal weighing more than 1100lbs (500kg), or the equivalent of about 20 people.

Symptoms include difficulty breathing, vomiting, dizziness, difficulty speaking and neuromuscular paralysis.

The bite of the Cobra must be treated very quickly because the venom acts very quickly in the body, leaving only 30 minutes before the first symptoms appear and a few hours before death.

There are antivenoms to counter the effects of its poison, but their effectiveness is not always good enough to save a person. This is why many bites from this snake often result in death.

Finally, an inherent characteristic of the Philippine Cobra is that it can spit its venom up to 9ft (3m), resulting in a total loss of sight if it reaches the eyes.

4. Black Mamba

Black mamba

The Black Mamba is a very venomous species belonging to the family Elapidae. Very famous for its danger in Africa, this snake is one of the most widespread on the continent.

Reaching up to 10ft (3m), this reptile is known to be very fast in its movements: up to 12mph (20kmh).

When it attacks, the Black Mamba bites several times. Its venom is called “dendrotoxin“, a neurotoxin that acts on the nervous system and can cause paralysis of the respiratory muscles.

The lethality of its venom depends on several elements, including the amount of venom injected and the area bitten. It usually injects 100 to 120 mg of poison, and can go up to 400 mg in some cases. This data is quite worrying when you consider that only 10 to 15 mg are enough to kill an adult man.

This African snake considers man as a predator and attacks him only when he feels threatened. Most bites occur when a person is in its living area.

3. Common Death Adder

Common Death Adder

With its revealing name, this snake could not escape our classification. Despite its viper-like appearance, this snake does not belong to the Viperidae family, but to the Elapidae family. Considered one of the deadliest snakes in the world, the Common Death Adder lives only in Australia.

Its venom is a powerful neurotoxin with a lethal dose of 0.4mg/kg to 0.5mg/kg. During a bite, it can inject between 40 and 100mg, which means that death happens very quickly if it is not treated very quickly, only 6 hours. The main symptoms are paralysis and respiratory arrest.

Although there are antivenoms for Common Death Adder, many still die from this poison because the antivenom only slows the spread of the venom, but does not seem to stop it.

2. Belcher’s Sea Snake

belcher's Sea Snake

The Belcher’s Sea Snake is, as its name suggests, an aquatic snake of the family Elapidae that lives in the deep seas of South Asia.

This snake has long been considered the most venomous in the world and this is quite normal, as a single bite from this snake can cause death in less than 45 minutes. However, it takes the second place in our ranking because in addition to very rarely attacking humans, this reptile is able to control the dose of venom it injects and only a quarter of its bites contained venom.

Despite this, its venom is still extremely potent as a single dose of its neurotoxic and myotoxic poison can kill up to 100 people.

The symptoms are numerous and include respiratory and renal failure, profuse bleeding, convulsions, total paralysis…

As you can see, even if you have little chance of being attacked by the Belcher’s Sea Snake, a bite from it must be treated very quickly.

1. Inland Taipan

Inland Taipan

And here is the big winner of our ranking, the Inland Taipan.

Located only in Australia, it is the most venomous land snake in the world.

To give you an idea of its toxicity, its venom is 50 times more powerful than the Cobra, with very high levels of neurotoxins. The venom of the Inland Taipan can kill a person in just 30 minutes, and a single bite can kill up to 150 persons.

Fortunately, this snake is shy and not very aggressive. The effects on the nervous system result in total paralysis. Blood clots can also form and prevent circulation in the blood vessels.

There is an antivenom for the Inland Taipan, but the number of deaths from its bite is still very high. Without antivenom, only one person managed to survive.

And that’s it, this Top 10 of the most venomous snakes in the world is now over. These animals that fascinate as much as they scare can be deadly for humans. For all that, they are not predators for humans as many only attack as a last resort, preferring to flee if possible.
