List of Top 10 Deadliest Snakes in the World

Snakes are one of the most feared creatures on the planet. These limbless, cold-blooded carnivores strike terror into the hearts of anyone who comes across them. It doesn’t matter if they are venomous or not; the first sign of a snake makes people anxious. And there’s a good reason behind such behaviour.
Snakes have been the subject of misconceptions and mythical tales since time immemorial. Some cultures even worship snakes. Many mythical serpents like dragons, the Echidna and the basilisk have been inspired by snakes.
It’s rare for snakes to attack humans without provocation, and they are more scared of us than we are of them. Yet they feature the second-highest human kill count for any animal. However, some snakes are more deadly and aggressive than others. Read on to learn about the top 10 deadliest snakes in the world, from black mambas to king cobras.
List of the Top 10 Most Deadliest Snakes In The World
Snakes are less common in the northern hemisphere and are mainly found in deserts. India, Australia, and North Africa are home to most of the world’s dangerous and venomous snakes. Let’s find out more about the deadliest snakes on the planet, their size, kill count, and location.
10. Black Mamba

The black mamba is found in southern and eastern areas of Africa and is one of the longest and fastest snakes in the world. Black mambas can grow up to 14 feet in length and slither at speeds of 12.5 miles per hour. Their large size, combined with their agility, makes them lethal predators.
Black mambas have light grey or brown coloured skin, but get their name from the dark colour of the inside of their mouths. The black mamba’s venom is neurotoxic in nature and works extremely quickly. An infected individual experiences intense pain at first and passes into a coma within an hour. You’ll be dead from the black mamba’s venom within 6 hours without an antidote.
9. Boomslang

Boomslang is a large, extremely venomous snake found throughout the African continent, but mainly in southern countries like South Africa, Swaziland, Namibia, and Zimbabwe. The snake is known for its distinctive look, featuring large eyes, bright-coloured bodies, and an egg-shaped head. Boomslang males are generally green with blue or black scale edges, while females are often brown.
The boomslang snake doesn’t spray its venom and instead chews on the prey till it succumbs. The boomslang venom is a hemotoxin that destroys red blood cells and causes serious internal and external bleeding from every orifice of the body until death.
Another lethal attribute of the boomslang is that it only needs to inject the victim with a small dose of venom, and the symptoms often show up when it’s too late.
8. Fer-de-Lance

Fer-de-Lance has a spear-shaped head and a long, brown-coloured body with diamond-shaped spots. Fer-de-Lance venom has anti-coagulation properties and causes death from a brain haemorrhage. Its venom takes effect within minutes and often results in severe necrosis, turning body tissue black.
