The Top 8 Most Venomous Snakes in The World

8 The Black Mamba (Dendroaspis polylepi)

black mamba
Found in central Africa. Mambas aren’t actually black, but vary in colour from olive to brown. Black mambas are lethally venomous and when threatened (which is very often in their mind) extremely dangerous. Symptoms of their bite may include trouble breathing, paralysis and neurological problems. They can grow up to 4.5 metres in length and are among the fastest snakes in the world, reaching speeds of 20 kilometres an hour with ease. They live for approximately 12 years.

7 Terciopelo (Bothrops asper)

Found in eastern Mexico, Ecuador, Colombia and some parts of America, the Terciopelo can grow up to 6 ft. A single female can give birth to up to 100 off spring. Their venom can cause blood clots and by extension heart attacks, strokes and other serious medical problems. They live in the range of 15 – 21 years.

6 Boomslang (Dispholidus typus)

Boomslang (1)
Found in central/southern Africa, these snakes tend to favour wetter areas to dry areas. Its name means tree snake in Afrikaans and Dutch – which is a reference to how the snake hunts, by mimicking a tree branch. The boomslang rarely bites humans unless handled. They live for about 8 years.

5 Eastern Tiger Snake (Notechis scutatus)

Found in south eastern Australia, the Eastern Tiger Snake held the record for the most Australian snakebite fatalities due to its highly toxic venom and aggressive behaviour. It is generally 3.5 feet in length but has been known to reach 6+ feet. They are mainly active during the day but have also been known to be semi-nocturnal on hot nights.

4 Saw-Scaled Viper (Echis carinatus)

The Saw-Scaled Viper is highly venomous and is listed as one of Southern Asia’s most dangerous snakes. They are commonly found living in close proximity to people and are very quick to bite when threatened. They are mostly nocturnal (burying themselves in sand during the day) and hibernate during the winter in colder climates. They can live for up to 24 years of age.

3 Banded Krait (Bungarus fasciatus)

Found throughout Thailand and most of Asia, the Banded Krait is a highly venomous snake, deadly and common in Thailand, which can grow up to 2 metres long (6.5 ft.). The snake lives on the ground, in rat holes, termite mounds, under stumps or rocks and in other cool, damp places. Their venom paralyses your muscles and your diaphragm can’t work any longer to pull oxygen into your lungs causing asphyxiation. Their lifespan is unknown.

2 King Cobra (Ophiophagus hannah)

The largest venomous snake in the world, reaching enormous lengths of 18 feet, and with the ability to lift up to a third of its body straight off the ground and still be able to move forward to attack. They are also notorious for how they flare out their hoods to make themselves look a lot more intimidating. They are shy and will avoid humans whenever possible (thankfully) although when they do bite they have enough killing potential to kill 20 humans in a single swoop. They live mainly in the rainforests and plains of china. They live, on average, for 20 years.

1 Taipan (Oxyuranus microlepidotus)

The most venomous snake in the world, the venom from a single bite of the feared Taipan is enough to kill 100 men. Thankfully, they rarely bite humans and for the few cases that occur, an anti-venom has been discovered. The animal dramatically changes colour throughout the year to adapt to the seasons. It is lighter during the summer months than it is during winter, as this can help the snake to keep its body temperature constant.
