10 Most Dangerous Snakes in the World


While many people love snakes and even keep them as pets, others are flat-out terrified of them. Fear of snakes is so ubiquitous that snakes are traditionally used to symbolize evil in mythology, literature, and film.

Of course, snakes are not evil, and many of them are quite docile, even friendly. But a number of species can be quite dangerous if you cross them in nature, especially if they feel threatened. Even snakes that are generally friendly can kill you with their venom if you take them by surprise. Here are 10 of the most dangerous snakes on the planet.

1. Belcher’s Sea Snake

These slender, striped snakes may be familiar to you, perhaps even from personal experience. Sea snakes are typically pretty passive and won’t harm you unless they feel threatened. A threatened sea snake may bite you, releasing its venom. Only about a quarter of sea snake bites contain venom, but the sea snake is the most venomous snake on the planet. A few milligrams of Belcher’s Sea Snake venom is enough to kill a thousand people, making the sea snake the most dangerous snake in the world in terms of venomousness—even though it is typically harmless.

2. Rattlesnake

The rattlesnake is one of the most recognizable snakes in the Americas. It’s hard to miss the rattle at the end of the tail which gives this snake its name. The rattlesnake is actually a type of viper, and is quite venomous. The most dangerous snakes in this species are the young Eastern Diamondbacks. When treated promptly, fewer than 4% of rattlesnake bites are fatal, but when left untreated, all bites are potentially lethal. Rattlesnake venom can damage organs and prevent blood from clotting, leading to paralysis, breathing problems and massive bleeding. Losing a limb is not uncommon.

3. Death Adder

Everyone knows the story about how Cleopatra killed herself with the aid of an adder. This type of adder is found in Australia and New Guinea and looks a lot like a viper. Death adders are so dangerous that they hunt down other snakes, hiding in wait before leaping out and attacking their prey. Venom from a death adder will cause paralysis, respiratory failure, and death within just six hours. Around half of all untreated patients will die from Death Adder bites. With prompt treatment however, death is unlikely.

4. Inland Taipan

The venom from a single bite of an Inland Taipan can kill as many as 100 people. That may seem like nothing compared to the Belcher’s Sea Snake, but it’s still pretty impressive! While the rattlesnake is the most dangerous snake in the Americas, this snake is ten times more venomous. It is fairly passive however and keeps to itself; encounters with the Inland Taipan are relatively rare.

5. Eastern Brown Snake

The Eastern Brown Snake is not only very venomous, but also very aggressive, which makes it one of the most dangerous snakes in the world. This snake is native to Australia, and will often make its home in populous locations. Furthermore, it will actually chase down a person it perceives as a threat. It prefers not to bite, but will do so repeatedly if it decides to attack. Less than half of the bites are poisonous, but they do contain neurotoxins which cause paralysis and can be lethal.

6. Blue Krait

This species, native to South East Asia and Indonesia, has venom 16 times stronger than a cobra’s. Unfortunately, antivenin is not as effective against Blue Krait bites as it is against other types of snake bites. This makes it one of the most dangerous snakes, but fortunately the Blue Krait is nocturnal, so if you don’t roam around at night in the underbrush, you will probably avoid a Blue Krait encounter.

7. Black Mamba

The Black Mamba is native to Africa. While it may not be the most venomous snake in the world (one bite may only deliver enough venom to kill 10 people), it is still arguably the most dangerous snake in the world for other reasons. It is the fastest snake on earth, able to travel as fast as 20 km/h. A Black Mamba may strike its target a dozen times in a row. Without prompt treatment, a Black Mamba bite is almost always fatal.

8. Tiger Snake

The Tiger Snake is yet another dangerous snake native to Australia. This wide, yellow-banded snake is feared for the accuracy of its strikes. Without treatment, the fatality rate is generally around 70%. Like most other snake venoms, Tiger Snake venom causes paralysis, which may lead to respiratory failure and death.

9. Philippine Cobra

Cobras are highly recognizable because of their wide neck collars, but most species of cobra aren’t among the most dangerous snakes in the world. The most deadly cobra is the Philippine Cobra. It can spit its venom as far as 3 meters to reach its target. A bite from the Philippine Cobra can lead to death from paralysis within a half hour.

10. Saw Scaled Viper

This is one of the most dangerous vipers, along with the Chain Viper. This type of viper can be found in the Middle East and Far East, and is usually most active during nighttime following rain storms. Vipers are very fast, but their venom is relatively slow-acting. With antivenin, death is rare, but if you do not receive medical assistance, you can die a slow painful death over the course of 2 to 4 weeks.

As you can see, there are a number of different factors which can make any given snake deadly: the toxicity of its venom, the speed of attack, the aggression, and the likelihood that you would encounter that snake at all. The good news is that most snakes will only target you if they believe that you are a threat to their lives or to their young, and most bites can be treated effectively with antivenin, but you need to be fast.

      No. If you mean the Inland Taipan has the most toxic venom. The Inland Taipan certainly doesn’t have the most toxic venom. As this says (didn’t you read it?) the species with the most toxic venom of all the snakes known BY FAR is a sea snake.

      • Rushray

        December 8, 2014 at 1:24 pm

        sea snake has very dangerous venom it can kill lots of people in just one drop but in sea snake the quantity on venom is very less most venomous is king cobra because quantity is very very high as compared to others :)

          actually the inland taipan is the most venomous. it’s venom is twice as strong as the most venomous sea snake (which is actually Dubois’ sea snake) look hear is a paragraph from wiki.
          Belcher’s sea snake (Hydrophis belcheri), which many times is mistakenly called the hook-nosed sea snake (Enhydrina schistosa), has been erroneously popularized as the most venomous snake in the world, due to Ernst and Zug’s published book “Snakes in Question: The Smithsonian Answer Book” from 1996. Associate Professor Bryan Grieg Fry a prominent venom expert has clarified the error: “The hook nosed myth was due to a fundamental error in a book called ‘Snakes in question’. In there, all the toxicity testing results were lumped in together, regardless of the mode of testing (e.g. subcutaneous vs. intramuscular vs intravenous vs intraperitoneal). As the mode can influence the relative number, venoms can only be compared within a mode. Otherwise, its apples and rocks.” [11] Belcher’s sea snake’s actual LD50 (recorded only intramuscularly) is 0.24 mg/kg[73] and 0.155 mg/kg,[72] less lethal than other sea snakes such as the olive sea snake (Aipysurus laevis) 0.09 mg/kg and the most toxic intramuscularly, recorded of the sea snakes – the black-banded robust sea snake (Hydrophis melanosoma) 0.082 mg/kg. The black-banded robust sea snake has also been tested subcutaneously registering at 0.111 mg/kg. more than four times less toxic than the inland taipan’s venom. In the LD50 subcutaneous test it is actually Dubois’ sea snake (Aipysurus duboisii) which has the most toxic venom of the any of the sea snakes tested, registering at 0.044 mg/kg. This is still nearly half as lethal as the inland taipan’s venom.[72]

    I’d add Puff Adders to the list. Venom is necrotic and may not kill but you’re more likely to get bitten by a Puffie when walking through brush than any other snake. They’re lazy and often sunbathe in paths and dont move away like most other snakes when the feel you approaching. Next thing you know you’ve stepped on it and its bitten you.
    Treating wounds is hard because of the necrotic venom and its eats away at the tissue around the bite. If not treated you could lose the limb.

    I’ve been bit by one once, fortunately the bite didn’t make it through my leather gaiters and horse riding boots. I didn’t even realise it was a Puffie til it slithered away.

      I would have too disagree with all data, wrangling snakes worldwide the two that I really do not like catching because of their total aggression are 1. The eastern or commen brown,and I definitely would never turn my back on it as with 2 the black mumba. I do know the. Belchers sea snake has the strongest venom,but I have spent hours swimming and playing with this wild species as far as letting it run through my closed hand. That I would never do with hundreds of lesser venomous land species .so I’ll leave it to you. But I must say if you rare not properly trained, please leave all snakes alone and I’m sure that they will do the same for you.

    To all those who left a comment.
    You can ask many specialists, doctors, farmers, african tour guide like me and believe me every list will rank different and all might be right too!!!
    As he wrote their are many factors you can/have to take into consideration and this will result into the ranking.
    Make a google test which snake kills most people on earth and you see that this one is not even on the list!!! (Russel Viper)
    some snakes are very venomous but their venom production is low so for a defensive bite they do not open the venom bags and you end up with a so called try bite.
    In latin america there is a snake called Bushmaster which has a proven fatality of 40% even with antivenom!!!!! even this snake you can not find on the list which is strange to me!!! In the amazone you have small snakes like a pencil which are fatal, not on the list.
    What I want to say is that the internet has only so much truth as the people have knowledge which are feeding the net………
    To come back to snakes, every human body will react different to a bite, I was biten by a southafrican boomslang (english tree snake) in 1989 and I got antivenom within half hour but my body reacted much worse than other people the doctor said and even with antivenom my next bite (of course to be avoided) might be my last one
    So try to avoid snake bites at all and definitely never foul around with any

    The list noted the most dangerous snakes in the world.
    The sea snake should not be on this list.
    It rarely bites.

    The list should be based on the number of bites in relation to the number of people in the proximity.
    Puff Adders and Carpet Vipers bite more snakes in Africa than any other snake.
    In South Africa, in spite of its fearsome reputation, the black mamba is definitely not the most dangerous snake.
    There are more recorded bites accredited to the cape cobra and Mozambique spitting cobra.
    The black mamba has the fasted acting venom of any snake in the world, and injects up to 450mg Ina single bite, and only 10-15mg is required to kill a grown man…. You do the maths!

    While the LD50 rating is far lower than that of the Inland Taipan, the mamba bites far more people, and much quicker acting venom.

    The. Oust dangerous species of snake would be the ones found in highly populated areas, such as India, where humans and snakes often come into contact.

    These lists too often cause loyalists to their countries snakes to get heated and fiercely defend their countries snakes.
    It’s quite laughable actually.

    As suggested repeatedly here and elsewhere, beyond the particular loyalties to town or country of origin the snakes aren’t in competition with themselves. This writers humble opinion is the result of some experience. The most dangerously venemous snake in the whole world is the one you just stepped on.
    Good Luck with that!

    Black mamba is most danger snake

    • Chris

      February 9, 2015 at 12:09 pm

      The article says of the Belcher Sea Snake… ‘ it is the most dangerous snake in the world in terms of venomousness”. This statement is not true. The Belcher sea snake is often incorrectly reported as the most venomous snake in the world and this article makes the same mistake. It is the 2nd most venomous snake in the world. Ask any reputable herpetologist and they will all tell you the same thing. In terms of volume, the MOST venomous snake in the world is, BY FAR, the inland taipan of Australia. It is almost twice as venomous as the Belcher Sea snake at 0.025 mg/kg for the inland Taipan vs 0.044 mg/kg for the Belcher Sea Snake ( the smaller the number the more venomous the snake). Cobras, Mambas and Vipers don’t even crack the top 12 in terms of most venomous snakes.

      This is NOT to say that the inland Taipan is the most dangerous (read aggressive). Both it, and the Belcher sea snake are very docile creatures that will not bite unless cornered and severely provoked. Insofar as aggressiveness and danger the black mamba has the highest mortality rate in the world due to its fast acting venom but it is only responsible for between 1/2% and 1% of snakebite deaths in Africa. Both the Black Mamba and the Coastal Taipan are popularly regarded as the most dangerous and feared snakes due to their very aggressive and nervous nature; however, in Africa, the ocellated carpet viper is responsible for more human fatalities due to snakebite than all other African species combined If you want to know overall fatalities then the Puff Viper is responsible for the most fatalities worldwide.

      Now you know.
