The Carpet Viper — found in the dry regions of Africa, the Middle East, India, Pakistan, and Sri Lanka, this snake appears to be responsible for more fatalities than all other African snake species combined, killing an estimated 20,000 agricultural workers each year.
Venom Strength — Powerful enough to cause terrible pain and swelling around the bite area, the venom also causes blistering and tissue damage.
Aggressiveness — Carpet Vipers are known to be very aggressive animals.
Overall Danger — The West African Carpet Viper has a LD50 of 2.71mg/kg, meaning its venom would kill over 200 mice. Even though the snake does not have the most potent venom, it is considered the most dangerous snake to humans when taking all things into account..
Overall Danger — Rating this snake from very shy to very aggressive, the Carpet Viper ranks as very aggressive.
Chance of Encounter — They will live close to humans. They’re known to favor arid climates and will keep themselves buried in the sand, hiding from humans. They make a hissing sound when threatened. If you’re visiting a part of the world in which they live, listen for the warning sounds.
Story — In 2012, a 57-year-old grandmother in Derbyshire, England spied a snake hiding underneath a crate that had been shipped from India.

The 20-inch snake apparently hitched a ride on the crate all the way from India.
Belcher’s Sea Snake — Known as one of the top 3 most venomous snakes in the world, Belcher’s Sea Snake, can be found in the Philippines, New Guinea and Australia.

Aggressiveness — The Sea snake is actually passive, and won’t try to harm you unless it feels threatened. It would actually take a lot of provoking to make it attack you.
Overall Danger – This species of snake has not been studied extensively, but one experiment claims an LD50 of .024 mg/kg.
All things considered, this snake is not considered very dangerous to humans.
Overall Danger — Because the Sea Snake tends to be timid, we’d rate it as Very Shy … and a good thing, too!
Chance of Encounter — Your chance of running into one of these snakes is relatively low since they’re so passive.
Story — The Sea Snake’s victims tend to be fishermen. The fishermen sometimes unintentionally grab the snakes when they pull in their nets. Lucky for them less than a quarter of the sea snake’s bites will contain venom. Still, would you want to play those odds?
Black Mamba — Native to Africa, it’s not necessarily the most venomous snake in the world but it is considered one of the most dangerous.
Venom Strength — The Black Mamba’s venom is strong enough to kill 10 to 25 adults. The neurotoxin can cause respiratory arrest, coma and death. Without antivenin, the Black Mamba’s bite has a mortality rate of 100%
Aggressiveness — These snakes are known to stand their ground, especially when cornered. They’re considered to have highly aggressive temperaments, and can strike up to a dozen times in a row.
Overall Danger — The Black Mamba can be considered extremely dangerous thanks to its LD50 of 0.25, which could kill 40,000 mice.
Overall Danger — Because they’re the world’s fastest land snake and can reach speeds up to 20 kilometers per hour, we rate them as very aggressive
Chance of Encounter — These snakes are commonly found throughout southern and eastern Africa, from savannah’s to open forest areas.
Story — In 2012 a wildlife photographer was bitten while photographing his subject — a Black Mamba! Mark Laita was taking pictures for his photography project called, appropriately “Serpentine” when it happened. Luckily for the photographer, it was a ‘dry bite’ … meaning no venom was actually injected.
Blue Krait — Also called the Malayan Krait (krite), it’s found throughout Indonesia and Southeast Asia.
Venom Strength — They carry a neurotoxin that’s 16 times more potent than a cobra’s, and induces muscle paralysis. Death often occurs within 6-12 hours of a Krait’s bite. Even with antivenin, 50% of their bites can be fatal.
Aggressiveness — They’re nocturnal animals and tend to be more aggressive when it’s dark. But they’re timid overall, and will usually try to hide rather than fight. The Blue Krait are known for hunting and killing other snakes, even cannibalizing other Kraits
Overall Danger — These snakes tend to be passive. With an LD50 of 0.12mg/kg, the Blue Krait ranks as a potentially dangerous animal.
Overall Danger — Due to the animals’ passivity, they not considered dangerous snakes. We rate them as ‘very shy’.
Chance of Encounter — Since they usually come out at night, it’s less likely to meet up with them.
Story — A man called the Snake Ninja had a unique way of protesting Amazon deforestation. He filmed himself putting both a venomous Blue Krait snake and a Poison Dart Frog in his mouth, and letting the creatures wriggle around in there before releasing them into the wild.
Fierce Snake or Inland Taipan (tie-pan) — Found in semi-arid regions of Central-east Australia, this is considered drop for drop the most toxic among all snakes.

Chance of Encounter — The snake isn’t usually encountered by humans in the wild.
Story — Tim Friede is a 37-year old Wisconsin man who claims to be immune from the deadly venom of five of the world’s deadliest snakes including the Inland Taipan, Black Mamba, and rattlesnakes. In 16 years of research this amateur scientist has self-inflicted over 160 snake bits in the hopes that his experiments can aid in creating a human vaccine for snake bites. While his efforts are noble, his ability to self-immunize has come at a cost of his marriage.
Rattlesnake — Easily distinguished by the rattle on the end of its tail, they can strike at distances up to two-thirds their body weight. The Eastern Diamondback is thought to be the most venomous species in North America.
Venom Strength — Most species of Rattlers carry a hemotoxic venom which will degenerate organs and disrupt blood clotting. Untreated rattlesnake bites can potentially be fatal. But if antivenom is applied in time, the death rate falls to under 4%
Aggressiveness — These snakes will only strike when threatened, and will usually seek any chance to escape confrontation.
Overall Danger — The Eastern Diamondback Rattlesnake’s LD50 is 1.65 mg/kg and could kill over 12,000 mice, making the animal potentially dangerous. These animals usually try to avoid confrontation
Overall Danger — Because Rattlesnakes usually seek to avoid danger, we’d rate them between shy to aggressive.
Chance of Encounter — There are 32 species of rattlesnakes in the US, with most of them being found in the southwestern part of the country.

Aggressiveness — It is known to have a considerable temper. Along with its toxic venom, it could cause some potentially dangerous conflicts with humans.
Overall Danger — The Eastern Brown Snake’s venom carries an LD50 of 0.53mg/kg meaning it could kill over 70,000 mice. This snake would be extremely dangerous.
Overall Danger — Because of the animal’s temperament, we’d rate the Eastern Brown Snake as Very aggressive, and should be avoided. They’re very territorial, and will chase humans out of its territory.
Chance of Encounter — The snake feeds mostly and small mammals, mice and rats in particular. Preying on small mammals will often bring it into contact with humans around farm buildings.But these snakes can also be found in cities as well

Indian Cobra — Found throughout India, Pakistan and Sri Lanka, this snake is easily recognized by its spread hood, and can grow up to 6 feet long.

Cottonmouth — Also called Water Moccasins, these snakes are found in the southeastern United States, They can reach lengths up to 4 feet and are part of the pit viper family.
Venom Strength — These snakes produce a hemotoxic venom that inhibits the victim’s blood to coagulate or clot. That causes a hemorrhage across any portion of the victim’s circulatory system penetrated by the venom. The damage they cause can be severe and sometimes fatal.
Aggressiveness — Cottonmouths aren’t known for their aggression, and won’t attack unless becoming agitated. If that happens, the snake will open its mouth wide and expose its fangs, and the white lining of its mouth — which is where it get its name.
Overall Danger — The Cottonmouth has an LD50 of 2.044 milligrams per kilogram. LD50 refers to a Lethal Dose of the snake’s venom that would kill 50 percent of the members of a test group of mice. The Cottonmouth LD50 means it would kill over 2,000 mice. Because they’ll stand their ground when provoked, that makes them somewhat dangerous.
Chance of Encounter — These snakes are nocturnal animals and usually inhabit swamps, or will live at the edges of lakes, or slow-moving waters. You’d likely have to go out of the city to encounter one.
