20 Most Venomous Snakes in the World

most-venomous-snakes-in-the-world

The World Health Organization estimates that up to 94000 people per year are killed by venomous snakebites.

Venomous snakes kill their prey by injecting toxic venom with their fangs. Such venom can cause a wide range of symptoms in its victim, from paralysis and internal bleeding to tissue death.

Here is a list of 20 of the most venomous snakes on the planet

20. Eastern Green Mamba

The eastern green mamba, a member of the mamba genus Dendroaspis, is a highly venomous snake found along the coasts of southern East Africa. It is characterized by a vibrant green color on its scales.

Birds, frogs, rodents, lizards, and other small mammals make up the bulk of this snake's diet.

Mambas can reach speeds of 7 miles per hour, making them one of the fastest snakes.

It has neurotoxins and cardiotoxins in its venom. If you happen to get bitten by a green mamba you will experience swelling at the injection site, dizziness, and nausea, followed by trouble breathing and swallowing, irregular heartbeat, convulsions, and eventually respiratory paralysis.

19. Common Death Adder

Their ability to blend in seamlessly with their surroundings is crucial to their survival. Death adders are ambush predators that remain hidden waiting for passing prey.

The common death adder is one of seven species of death adder found in Australia.

They are capable of striking with devastating speed which earns them the title of fastest striking speed snake in Australia.

The introduction of the highly invasive cane toad poses a greater threat to death adders' habitats. These toads are known to prey on baby death adders. Toxic glands in cane toad skin are also fatally poisonous to adult death adders if they eat these amphibians.

18. Malayan Krait or Blue Krait

The Malayan krait, native to Southeast Asia, is a highly venomous snake. They tend to live in wet environments, such as forests or plantations near bodies of water.

Besides preying on other snakes, their diet also includes lizards, frogs, mice, and other small animals.

Krait bites are often painless and happen at night, with some victims even getting bitten while they sleep.

17. Yellow-bellied Sea Snake

Native to Africa, the Mozambique spitting cobra is one of the most poisonous snakes in the world.

These snakes can hit a victim's eyes from 1.5 m away with 90% accuracy. Venom to the eyes can cause blindness.

Its bite causes extensive damage to surrounding tissue. This species' venom contains both a postsynaptic neurotoxin and a cytotoxin.

15. Eastern Diamondback Rattlesnake

most-venomous-snakes-in-the-world

Rattlesnakes are found throughout the US, but they're most common in the Southwest. The eastern diamondback rattlesnake is one of the biggest and most venomous rattlesnakes.

Tissue around a bite from a rattlesnake is damaged by the venom. Venom can change blood cells, prevent blood clotting, and damage blood vessels, causing them to leak. Internal bleeding and failure of the heart, lungs, and kidneys can result from these alterations.

14. Philippine Cobra

most-venomous-snakes-in-the-world

The northern parts of the Philippines are home to Philippine cobras, as their name implies.

The neurotoxins in Philippine cobra venom disrupt the transmission of nerve signals by binding to neuromuscular junctions close to the muscles, leading to neurotoxicity and respiratory paralysis, all of which have an impact on respiratory function.

13 .Beaked Sea Snake

Beaked sea snakes are commonly spotted in the oceans off the coast of India and the nearby islands.

Marine Education Society of Australia claims that "this common species is responsible for nine out of every ten deaths from sea-snake bites."

12. The Krait/Dubois Sea Snake

The Dubois sea snake is crowned the most toxic snake in India.

Some say it's the deadliest sea snake there is.

It's also worth noting that water snakes and sea snakes are not the same thing. Sea snakes are found in oceans and are extremely poisonous, but their river and lake dwelling counterparts are typically non-venomous.

11. The Saw scale Viper

most-venomous-snakes-in-the-world

The name of this snake comes from the serrated edges of the scales that run along its lower body at a distinct 45 degree angle from the rest of its body.

They can be found in the Middle East, northern Africa, Sri Lanka, and some parts of India.

Their haemotoxic and cytotoxic venom prevents blood clotting and damages cells and tissues.

10. Boomslang

most-venomous-snakes-in-the-world

The boomslang belongs to the family of Colubridae and is a large, highly venomous snake.

Boomslang venom is a hemotoxin. It can also cause other unpleasant effects, such as nausea, headaches, and drowsiness. This venom could also cause the victim to bleed from every orifice.

9. The Belcher's Sea Snake

most-venomous-snakes-in-the-world

Belcher's sea snake venom is so lethal that it can kill a human in under 30 minutes from a single bite. One study found that 1.5 milligrams of the venom was enough to kill 22 fully grown adults, suggesting it may be one hundred times more toxic than the venom of the Inland Taipan Snake.


Though it hasn't been conclusively demonstrated, this seems to lend credence to the idea that sea snakes are significantly more poisonous than their land-dwelling counterparts.

8. Tiger Snake

most-venomous-snakes-in-the-world

South Australia is home to tiger snakes, which are among the most venomous snakes in the world.

There are neurotoxins, myotoxins, and procoagulants in tiger snake venom that act both before and after a synaptic transmission. Paralysis, incoagulable blood, and muscle damage from bites can eventually lead to renal failure.

7. Coastal Taipan

most-venomous-snakes-in-the-world

Among Australia's snakes, the Coastal Taipan is widely considered to be the deadliest. They are highly anxious and vigilant snakes that will strike at the slightest provocation.

The fangs can be up to 12mm in length, making them the longest of any Australian snake.

Headache, nausea/vomiting, collapse, convulsions, paralysis, internal bleeding, destruction of muscle tissue, and kidney damage may result from the venom's effect on the nervous system and the blood's ability to clot.

6. Barbarra Amarilla or Fer-de-lance

most-venomous-snakes-in-the-world

The Barbarra Amarilla belongs to the venomous viper family. They were originally from the lowlands of South America's tropical zone.

This snake species is responsible for more human deaths than any other snake native to the Americas. A single bite from a fer-de-lance injects an average of 105mg of venom, though venom yields of up to 310mg have been recorded when milking them. For humans, 50 milligrams is the lethal dose.

5. Black Mamba

most-venomous-snakes-in-the-world

Black mambas can grow to be 14 feet long, making them the longest venomous snake in Africa.

Black mamba can reach speeds of 12.5 miles per hour, making them among the fastest snakes in the world.

As little as two drops of its venom is enough to kill a human.

4. King Cobra

most-venomous-snakes-in-the-world

The longest venomous snakes are the king cobras, which can grow to a whopping 18 feet in length.
Although its venom is not as potent as other snakes on this list, a single bite from one of these could be fatal for up to 20 people or even an elephant because of the large amount of neurotoxin it contains up to two-tenths of an ounce. King cobra venom affects brain respiratory centers, causing respiratory arrest and cardiac failure.

Typically, you can find them in the plains and forests of southern China, Southeast Asia, and India.

They are the only known species of snake that constructs nests to protect its eggs, which it then guards fiercely until the young emerge.

3. Many Banded Kraits

most-venomous-snakes-in-the-world

The many-banded krait is a venomous elapid snake that lives throughout much of central and southern China and Southeast Asia. It is also known as the Taiwanese krait and the Chinese krait.

The many banded krait has the most potent venom of any krait and is one of the most poisonous land snakes in the world.

Banded krait venom primarily consists of presynaptic and postsynaptic neurotoxins, both of which can cause paralysis of the skeletal muscles.

2. Eastern Brown Snake

most-venomous-snakes-in-the-world

The eastern brown snake is a highly venomous Elapidae snake. The species is native to Australia and New Guinea.

This snake is second only to the inland taipan in terms of venom potency among land snakes.

1. Inland Taipan

most-venomous-snakes-in-the-world

The inland taipan (Oxyuranus microlepidotus) is widely regarded as the world's most venomous snake.

The venom of the inland taipan is highly effective against mammals. The venom is highly neurotoxic and also contains a "spreading factor" (hyaluronidase enzyme) that speeds up the body's ability to absorb the toxin.

Dr. Geoff Isbister, a clinician and clinical toxicology researcher, claims that a bite from an inland taipan snake can be fatal within 45 minutes.
