  • Snakes- just the thought of one of these slithering murder-worms is enough to give most people

  • the chills.

  • With venomous fangs, muscular bodies that can crush the life out of a grown man, and

  • S tier stealth skills, snakes are nature's way of reminding us that she hates us.

  • But what are the largest snakes that ever lived- and more importantly, how many of them

  • are still around?

  • Warning, for anyone suffering from ophidiophobia you may want to tune out now or never go outside

  • again.

  • 20.

  • Eastern Diamondback Rattlesnake Rattlesnakes are known for one dominant feature-

  • their deathly rattle that they use to politely inform you that if you don't back off right

  • now, you're about to be in a world of hurt.

  • The Eastern Diamondback is king of the rattlesnake pile though, with specimens growing up to

  • 7 feet (2.1 m) and weighing on average up to 15lbs for large specimens (6.7kg).

  • But it's believed the diamondbacks can actually grow even larger than this, with at least

  • one documented specimen having reached an incredible 7.8 feet (2.4m) and 34 lbs (15.4kg)!

  • Luckily for you, most diamondbacks are much, much smaller than this, and their rattle will

  • warn you to stay well away from their highly venomous fangs.

  • 19.

  • King Cobra King Cobras average a length of up to 12 feet

  • (3.6 meters), but some specimens have been measured at a whopping 18 feet (5.4 meters),

  • and can weigh up to 30lbs (14 kg).

  • This snake combines the best of both worlds- if you're a snake anyways- with a muscular

  • body capable of crushing bone, and a deadly venomous bite that can leave a victim paralyzed

  • within minutes.

  • This snake is perhaps best known for its threat displays, when it'll rise up to four feet

  • off the ground and stare its victim in the face.

  • Despite its fearsome reputation though, King Cobras are notoriously shy creatures and typically

  • only attack when threatened, backed into a corner, or defending a clutch of eggs.

  • Surprisingly, regular rattler snakes in North America cause 5 times as many deaths per year

  • as King Cobras do across South East Asia.

  • 18.

  • Sanajeh Now it's time for our first prehistoric member

  • of this countdown, and if the fact that this snake appears at no.

  • 18 tells you anything, it's that this means most of history's deadliest snakes are very

  • much still alive in our modern era.

  • The Sanajeh hails from the late Cretaceous in modern day India, and was first discovered

  • coiled around an egg, adjacent to a sauropod hatchling.

  • From this scientists have inferred that the snake preyed on young dinosaurs and their

  • eggs, likely meaning that the snake was highly venomous as it would have to ensure a fast

  • kill in order to escape an egg clutch before mom and dad have a chance to respond.

  • Coming in at 11 feet (3.5 meters), Sanajeh was probably a pretty heavy snake given its

  • diet of large dinosaur eggs and their equally large hatchlings.

  • 17.

  • Olive Python You already know we couldn't possibly do a

  • video discussing terrifying animals and not include Australia.

  • God put Australia on the very southern edge of the world surrounded by oceans, and still

  • humans didn't get the message to keep out.

  • Coming in at 13 feet (4 m) and weighing as much as 40 pounds (20 kg), the Olive Python

  • has been giving unwary bushwhackers out on walk-abouts the hershey squirts for centuries.

  • Yet despite its impressive size and penchant for eating crocodiles, the Olive Python is

  • actually considered to be one of the friendliest snakes in the world, and pose no threat to

  • humans.

  • Snake owners rave about olive pythons for their beauty, but also their curious, calm

  • temperament when out of their cages.

  • 16.

  • Papuan Python If snakes had legs, they'd rule the world,

  • but thankfully for us evolution has limited their predatory advantages to keen senses,

  • muscular bodies, and venomous fangs.

  • But then evolution hacked the game and gave one species of python access to cheats- enter

  • the Papuan Python, a snake with chameleon-like powers to change its color.

  • Coming in at 17 feet (5m) and weighing up to 50 lbs (22.5 kg), the Papuan Python is

  • a terrifying predator in its own right, even without the added advantage of chameleon powers.

  • Scientists still don't understand how or why the snake can change colors, but this python

  • is capable of changing from jet black to mustard yellow, possibly depending on its mood.

  • 15.

  • Cuban Boa The one good thing about snakes is that at

  • the very least, they are solitary animals.

  • Or, at least they were until scientists discovered Cuban boas hunting together in a pack.

  • That's right, cuban boas took the advantage that humans, wolves, wild dogs, and lions

  • have- pack tactics- and added it to their already terrifying arsenal of natural advantages.

  • For now, these boas, which can grow up to 16 feet (4.8m) and weigh as much as 60 pounds

  • (27 kg) limit their pack hunting to bats, as dozens of the snakes line up outside of

  • cave entrances and snatch flying bats out of the air.

  • But it's only a matter of time before these huge snakes get a taste for man, and start

  • lining up outside of walmarts to prey on the unwary.

  • 14.

  • Dark Spotted Anaconda When people think anaconda they think of two

  • things- Sir Mix A Lot and the green anaconda.

  • However, the green anaconda may be the largest of its cousins, but is one of several species.

  • The shrimp of this absolutely monstrous family of snakes is still a significantly large snake

  • nonetheless, with the dark spotted anaconda growing up to 15 feet (4.6m) and weighing

  • up to 70 lbs (31 kg).

  • Primarily a water snake, the dark spotted anaconda preys on anything stupid enough to

  • enter the amazonian rivers where it makes its home.

  • 13.

  • Yellow Anaconda In what will definitely not be the last showing

  • for the anaconda family on this list, the yellow anaconda is slightly bigger than the

  • dark-spotted anaconda, reaching lengths of up to 15.1 feet (4.6 m) and weighing as much

  • as 77 lbs (35kg).

  • Its yellowish skin allows the anaconda to perfectly blend in with the murky waters of

  • turbulent rivers, or along the muddy banks where it stalks everything from large mammals

  • to crocodiles.

  • Perhaps unsurprisingly, yellow anacondas are not recommended to be kept as pets, as they

  • are extremely aggressive animals.

  • 12.

  • Boa Constrictor The Boa constrictor may also be called the

  • 'common boa', but there's very little that's average about this monster snake.

  • A common fixture in the homes of many of America's favorite creepy uncles that never got married,

  • the boa is notorious for eating pets and even children when poorly taken care of.

  • Coming in at sizes of up to 14 feet (4.3 m) and an average weight of 33 lbs (15kg), some

  • common boas have grown to absolutely monstrous sizes and weighed as much as 100 lbs (45 kg),

  • though thankfully for anyone that doesn't fancy being suffocated to death by a giant

  • snake as their ribs snap like matchsticks, it is incredibly rare for them to grow to

  • this size.

  • 11.

  • Bolivian Anaconda Coming in at 13 feet (4 meters) and weighing

  • just a little more than its yellow anaconda and dark spotted anaconda cousins, the bolivian

  • anaconda was believed to be a hybrid between yellow and green anacondas, but recent research

  • has confirmed that this frightening snake is a species all its own.

  • Thankfully this massive snake makes its home primarily in the jungles of bolivia and surrounding

  • areas, but is a notorious threat to domesticated wildlife and has been hunted to near extinction.

  • 10.

  • Yurlunggur Sounding like an Icelanding heavy metal band,

  • Yurlunggur is a prehistoric snake only recently discovered.

  • This massive 20 foot (6 meter) snake roamed Australia during the Miocene period, where

  • it hunted in packs of up to 30 snakes at a time and took down prey on land and sea.

  • Fine, we actually don't know anything about its hunting behavior as very little fossil

  • evidence of this snake has been discovered, but at this point given everything we've learned

  • about snakes so far we wouldn't be surprised if any of that was actually true.

  • Either way, we're glad this one's extinct, though Australia definitely has more than

  • enough modern horrors to worry about.

  • 9.

  • Amethystine Python The Amethystine python is one of six of the

  • world's largest living snakes, and if you're paying close attention you'll see that that

  • means only 3 of our top ten most terrifying snakes to ever live, lived in the ancient

  • past.

  • This means that our modern world may be the most terrifying place to live for anyone with

  • a fear of snakes.

  • Also known as the scrub python, there's nothing scrubbish about this massive snake which can

  • reach an incredible 22.7 feet (7 m) in length and weigh as much as 110 lbs (50kg).

  • This massive constrictor snake makes its home- where else- in Australia, along the northernmost

  • tip of the continent, and is endemic to Western New Guinea.

  • These massive snakes eat everything from birds, to possums, to even wallabies, and pretty

  • much anything that happens to wander by while it's feeling hungry.

  • 8.

  • Wonambi Yet another monster snake from Australia,

  • the Wonambi was well known to the aboriginals that inhabited the land down under.

  • Measuring between five and six meters long, this massive snake was known to lay in ambush

  • at watering holes, where prey would be forced to come to it.

  • Capable of killing and consuming a small child, aboriginal children were cautioned to never

  • approach a watering hole alone and wait for an adult.

  • Another non-venomous snake, the Wonambi instead preferred to crush prey to death before swallowing

  • it whole.

  • 7.

  • Indian Rock Python

  • The Indian Rock Python is peculiar for a snake, in that it's one of the few snakes that seems

  • almost reluctant to attack- even in self-defense.

  • Notoriously lethargic and very slow moving, these massive pythons have been known to go

  • up to 2 years without a meal.

  • When on the hunt though, the Indian rock python uses its muscular body to asphyxiate prey

  • before swallowing it whole.

  • The largest of these pythons ever officially recorded was discovered in pakistan and grew

  • to 15 feet (4.6m) and weighed in at 110 lbs (52 kg).

  • Curiously, these pythons are known to vomit up their meals if they feel threatened so

  • they don't accidentally puncture their own bodies on bones, hoofs, or antlers, before

  • slithering away to safety.

  • 6.

  • African Rock Python The largest snake in Africa, the African rock

  • python is the undisputed heavyweight of the African bush.

  • Growing up to 20 feet (6 m) and weighing up to an incredible 201 lbs (91 kg), there's

  • little this massive snake fears from Africa's other predators.

  • Thankfully, the average size of african rock pythons differs based on geography, with snakes

  • living closer to human settlements being smaller, and the uninhabited wilds of Sierra Leone

  • home to the true monsters of this species.

  • The true maximum size of this species is unknown, and rumors persist of even larger snakes such

  • as the one spotted by a World War II veteran pilot in the 1950s while flying a helicopter

  • in the Congo.

  • A passenger managed to take this photograph of the massive snake and though its true size

  • is impossible to estimate, it does appear to dwarf some of the large bushes and small

  • trees in the image.

  • 5.

  • Burmese Python In modern times, it doesn't get much bigger

  • than the incredible Burmese Python.

  • Growing up to 19 feet (5.8 m), the largest verified Burmese python weighed in at an absolutely

  • mind blowing 403 lbs (183 kg).

  • At these sizes, there's very little that's off the menu for this snake, and that includes

  • humans with stories of burmese pythons crushing humans to death and then eating them head-first

  • regularly reported in the media.

  • In 2018, a woman from Indonesia went missing after going to check on her vegetable garden.

  • What the rescue party discovered was terrifying- a monster of a python with a huge bloated

  • belly that when cut open, revealed the remains of the dead woman.

  • And if you think you're safe living in America, think again, as in 2019 a 17 foot python was

  • found in the US.

  • 4.

  • Reticulated Python Most snakes have a fairly limited range, which

  • is only expanded when humans who make terrible life decisions try and keep one as a pet,

  • only to realize it's far too difficult to handle such a massive snake and release it

  • into their local wilderness.

  • The Reticulated python, the longest living snake in the world, doesn't need humans to

  • spread its reign of terror, as it's an excellent swimmer that's been spotted far out at sea.

  • The largest recorded python weighed in at 350 lbs (159 kg) and was an incredible 25.2

  • feet (7.67 m) long, though it's believed that even larger specimens are possible in the

  • most remote areas of its south asian habitat.

  • Reticulated pythons have been known to kill and eat everything from sun bears to human

  • children.

  • 3.

  • Green Anaconda When you think man-eating snake, you probably

  • think of the green anaconda- and not without reason.

  • Averaging around 22 feet (6.7 m) in length, Green Anacondas routinely weigh as much as

  • 200 lbs (91 kg).

  • However, historical records have given us lenghts of almost 30 feet, and weights in

  • excess of 300 lbs.

  • Amazon natives have many stories of snakes even larger than this, with lengths of 35-40

  • feet (11-12 m) and weights of over 400 lbs (181 kg).

  • Historically it's been difficult to verify many of these encounters with monstrous snakes,

  • as these massively powerful animals are less than cooperative about stretching out so they

  • can be measured by scientists.

  • Given the incredible sizes other snakes can reach in areas untouched by humans, and the

  • long lifespan of an anaconda, such reports of monster snakes may not be without some

  • merit.

  • 2.

  • Gigantophis Until the discovery of the snake at the number

  • one spot on our countdown, Gigantophis was considered to be the largest snake that ever

  • lived.

  • Initial size estimates had it growing from 30 to 35 feet (9.3 to 10.7m), but revised

  • estimates have shorted this figure to just over 22 feet (6.9 meters).

  • Living during the Paleogene period, mammals were just beginning to diversify and celebrate

  • the fall of their cruel dinosaur overlords- until Gigantophis showed up to eat them whole

  • and remind them that reptiles were still the coolest kids on the block.

  • 1.

  • Titanoboa This is it, the snake that ruled them all-

  • the largest snake in all of discovered history.

  • While modern anacondas are rumored to grow up to 40 feet, the Titanoboa regularly grew

  • up to 42 feet (12.8 m) in length, and weighed in at an incredible 2500 lbs (1,135kg).

  • That makes the average titanoboa as heavy as a modern car, and as long as a school bus.

  • This pants-shittingly terrifying monster of a snake roamed the earth shortly after the

  • extinction of the dinosaurs, and along with its cousin Gigantophis, served to remind the

  • upstart mammals that reptiles are king.

  • Curiously, while titanoboa could have eaten literally anything that crossed its path-

  • except maybe another titanoboa- it's believed it was mainly a fish eater, which would help

  • explain how this massive snake carried its bulk around.

  • Such a heavy snake would have been poorly suited for hunting on land, and would need

  • the aid of buoyancy to move around quickly.

  • And there you have it, the 20 most terrifying snakes to ever live, and 20 reasons to never,

  • ever, leave your house again.
