What Are The Top 5 Deadliest Snakes In The World?

With over twenty different families and three thousand species Snakes can be found on almost every continent (accept Antarctica). They can range in size from the tiny, 10 cm-long thread snake to the Reticulated python of up to 8.7 meters (29 ft) in length. Yet only 10-15% of snake species are reported to be venomous. In this article I am going to run down what in my opinion are the five most venomous snakes that are out there. Each of which would almost certainly kill you if you didn't seek an anti-venom quickly after being bitten by one of them.


5. Black Mamba

Despite what you might believe, the ‘black’ in the name ‘Black Mamba’ does not represent the colour on the outside of the snake, but rather, it is the colour of the inside of its mouth which it will display if it feels threatened. Living mainly in eastern and southern Africa, it will, like most snakes seek to avoid contact with humans if possible. However, if it does start to feel threatened it will raise its head far off the ground in the way that a cobra does and then strike. It does not just strike once though. Rather it will keep biting and injecting its venom if it is stressed.

The average black mamba will grow between 2.5 and 3.2 metres; however, there have been reports of them reaching over 4.5 metres. It size does not limit it though, and it is still able to move around 5 metres per second (which equates to around 10-12 mph) and without rapid and vigorous antivenom therapy, a bite from a black mamba is almost always fatal. It is estimated that only 10 to 15 mg of venom will kill a human adult, but the Black Mamba bite delivers about 100–120 mg of venom on average.

4. Daboia (Russell's Viper)

The Daboia, or as it is sometimes known 'Russell's Viper' (in honor of Patrick Russell (1726–1805), a Scottish herpetologist who first described many of India's snakes), is largely found throughout Asia in countries like India and China. It can grow to a maximum length of around 1.6 meters (5.5 ft) although it usually averages about 1.2 meters (4 ft).

Apart from being a member of the big four snakes in India, Daboia is also one of the species responsible for causing the most snakebite incidents and deaths among all venomous snakes on account of many factors, such as their wide distribution and frequent occurrence in highly-populated areas.

The quantity of venom produced by individual specimens is considerable. Reported venom yields for adult specimens range from 130–250 mg to 150–250 mg. What must be remembered though is that 10-15 mg is enough to kill a human. That being said it may be seen that this snake is extremely venomous.


3. King Cobra

Similar to the Daboia, the King Cobra is found throughout Asia in places such as India. It is however, much larger than the Daboia and can reach a length up to 5.5 meters (18 ft). The king cobra averages at 3 to 4 m (9.8 to 13 ft) in length and typically weighs about 6 kg (13 lb) though.

Its generic name, Ophiophagus is a Greek-derived word which means "snake-eater", and its diet consists primarily of other snakes, including ratsnakes, small pythons and even other venomous snakes. In terms of venom this species is fully capable of delivering a fatal bite and the victim may receive a large quantity of venom with a dose anywhere from 200–500 mg which is enough to kill 20 humans easily...

2. The Eastern Brown Snake

The Eastern Brown Snake (or as it is sometimes known 'the common brown snake') is a species native to Australia, Papua New Guinea and Indonesia. This species has an average length of 1.1–1.8 m (3.6–5.9 ft). The maximum recorded size for the species is 2.4 m (7.9 ft), although any specimen of greater than 2 m (6.6 ft) in length would be considered exceptionally large.In terms of the venom that it has, it is considered to be one of the most deadly snakes that you can come across.

1. The Inland Taipan

The Inland Taipan (or Fierce Snake as it is sometimes known), is a snake which is found in Australia. It is considered the most one of the most venomous snakes in the world, however, it is a shy snake and will prefer not to bite if it can. The name fierce snake does not come from its temperament but rather the strength of its venom. It averages approximately 1.8 metres (5.9 ft) in length, although larger specimens can reach lengths of 2.5 metres.

The maximum yield recorded for one bite by these is 110mg, enough to kill about 100 humans, or 250,000 mice. The venom itself is considered to be 10 times stronger than a Rattlesnake, and 50 times more than the common Cobra.
