Snakes are among the most revered in the animal kingdom. They can be found in most regions of the world. From snakebites to other types of physical trauma, snakes can be lethal creatures capable of striking fear into anyone that crosses their path. Though, not all snakes are deadly. There are plenty of species that are not lethal and pose almost no threat to your health. In fact, the majority of the snake species are non-venomous.

The only continent where you will not find snakes is Antarctica. Though, there are some islands, including Ireland and New Zealand, along with various islands spread throughout the Atlantic and central Pacific, without any snakes.

There are about 3,400 different species, belong to more than twenty genetic families. They can vary from 10 centimeters in length (the thread snake) to 7 meters (the reticulated python).

Are you afraid of snakes? If not, you will be by the time you finish reading this list of the top 10 deadliest snakes in the world.

#10 – Rattlesnake


Rattlesnakes are the only American snakes on this list. The venom from the Eastern Diamondback rattlesnake is capable of potentially fatal injuries. The hemotoxic venom found in rattlesnakes is known to be able to destroy tissue, damage organs, and cause blood clotting. Any bite from a rattlesnake could lead to death, even with immediate treatment – which is a scary thought, as this is only the 10th deadliest snake in the world.

#9 – Death Adder

Death Adder

The name of this species should give you an indication that it is deadly. The Death Adder is found throughout Australia and New Guinea. It prefers to ambush its prey, including other snakes. They are capable of injecting between 40 and 100 milligrams of venom with a single bite. Once bit, the venom causes paralysis and has been known to kill in less than 6 hours, but there are antivenin treatments that can be used immediately to reduce the chances of death.

#8 – Vipers


Vipers can be found in a lot of different countries, but the most venomous of this species comes from the Middle East and China. The Saw Scaled Viper and the Chain Viper are fast and nocturnal. Their venom leads to swelling, bleeding, and a drop in blood pressure. Without treatment, death could occur at any point.

#7 – Philippine Cobra

Philippine Cobra

The venom from a Philippine Cobra can cause paralysis and death in just thirty minutes. Capable of spitting at a distance of 3 meters, the Philippine Cobra is highly lethal. By interrupting nerve signals, victims will begin to experience nausea, headaches, pain, diarrhea, dizziness, and convulsions, before eventually succumbing to death – if treatment is not administered quickly.

#6 – Tiger Snake

Tiger Snake

Another snake from Australia, the Tiger Snake can also kill in thirty minutes or less. Though, most victims pass between 6 and 24 hours after the bite. The fatality rate for victims of a Tiger Snakebite is between 60 and 70 percent – without an antivenin treatment. The Tiger Snake is not aggressive and will typically flee unless it is threatened or cornered.

#5 – Blue Krait

Blue Krait

With a fatality rate of 50 percent without treatment, the Blue Krait is incredibly lethal. They are generally found throughout South East Asia and parts of Indonesia. Krait snakes hunt other snakes and even cannibalize their own species. Though, when it comes to human interaction, they tend to be unaggressive unless provoked.

#4 – Eastern Brown Snake

Eastern Brown Snake

The Brown Snake is quick, aggressive, and deadly. Easily one of the deadliest snakes in the world – just 1/14,000th of an ounce of their venom could kill an adult human. Fortunately, only 50 percent of these snake bites actually contain venom and they will try to attack without biting if possible. This makes them less of a threat unless you continue to corner them.

#3 – The Belcher Snake

The Belcher Snake

The Belcher Snake is the only water snake on this list. It is a small snake that is often found throughout the waters off the coast of southeast Asian countries and Northern Australia. Less than a quarter of their bites contain venom, but just a few milligrams is strong enough to kill hundreds of peoples. Fisherman should be cautious of these snakes when pulling nets from the water.

#2 – Black Mamba

Black Mamba

Depending on who you ask, the African Black mamba is actually the deadliest snake in the world. Though, it is also sometimes beaten out by the next snake on this list. The Black mamba is native to sub-Saharan Africa and is the second-longest venomous snake. It also has the distinction of being the fastest moving land snake. So, it is one of the longest, fastest, and deadliest snakes on the planet – you do not want to mess with the Black mamba.

Due to its deadly nature, the Black mamba is one of the most feared snakes in Africa and has become part of local culture and folklore in parts of sub-Saharan Africa.

When attacking, the mamba mimics a cobra by spreading its neck flap and exposing its mouth. As it lifts its body off the ground to hiss at their prey, it can lift up to one-third of its length – reaching a height of up to four feet. It often strikes multiple times, targeting the head and body, while injecting large amounts of its lethal, toxic venom.

#1 – Inland Taipan

Inland Taipan

The inland taipan is often considered the most venomous and deadly snake in the entire world. Australia is starting to sound like a scary place, as the Inland Taipan is another snake found on the large island country. Their bites are almost always deadly unless an antivenin is administered. Though, even treatment may not be able to save a victim.

Now you have a list of snakes to keep away from. Though, if you are like most people, you will probably try to steer clear of any snakes in your path. Luckily, some of these species are only found in remote parts of the world or regions where you will never go. For further research – find out which snake species live in your region.
