If you’re into snakes, movie monsters, or just creature features in general, then you’re probably dying to know about the largest movie snakes of all time. Here, we’ll cover the five biggest snakes ever to hit the silver screen and learn about their real-life equivalents. You might be surprised to learn that not all the snakes on our list are giant snakes in real life. In fact, some of them aren’t even ten feet long!
Buckle in to learn about the ten largest movie snakes and the real-life snakes they’re based on!
5. King Cobra (1999)
One of the lesser-known but still interesting movies about giant killer snakes, is the film King Cobra. King cobra has one of the largest movie snakes, but it’s not just any snake. The monster star of King Cobra is actually a genetically engineered hybrid of a king cobra and an eastern diamondback rattlesnake. This monster snake (of course) goes on a killing rampage, using all of its 30 feet to hunt down the cast of the film.
Real Life Equivalent: King Cobra and Eastern Diamondback Rattlesnake
The monster snake in King Cobra is a combination of the king cobra (Ophiophagus hannah) and the eastern diamondback rattlesnake (Crotalus adamanteus). King cobras are the longest venomous snakes in the world, they can grow up to 19 feet long. Eastern diamondback rattlesnakes are the largest species of rattlesnake and may grow up to 8 feet long.
King cobras are highly venomous; they’re native to south and Southeast Asia. They can flatten their neck ribs to form the famous cobra hood like all cobras. King cobras eat mostly other snakes but will also eat lizards and rodents.
Eastern diamondback rattlesnakes are also highly venomous; they’re native to North America. Like all rattlesnakes, diamondbacks feast on rodents, birds, lizards, and occasionally smaller snakes. They’re known for their distinctive rattle, as well as for their unique diamond pattern.
4. Anaconda (1997)
The movie Anaconda began as a single horror movie based on giant killer snakes. It quickly grew into a film franchise of five feature and TV films, all based around the same snake: the anaconda. In the film, the movie snake measures 40 feet long and constricts its way through a documentary crew.
Real Life Equivalent: Green Anaconda
Green anacondas, also known as giant anacondas, are the heaviest snakes on Earth. They’re also among the longest snakes around. These constrictors can grow up to 17 feet long, and weigh over 200 pounds.
Green anacondas are native to much of tropical South America. They’re semi-aquatic and spend most of their time in or near fresh water. They even strike prey from beneath the water’s surface. Green anacondas eat everything from fish, lizards, and birds, to capybaras, caimans, tapirs, and deer.
3. Mega Snake (2007)
Filmed in Bulgaria and made for TV is the monster snake film Mega Snake. Unlike the rest of our largest movie snakes, this monster actually has a name: Unteka. Unteka starts out as a tiny snake in a jar, but through human negligence, it soon grows to 70 feet long.
Real Life Equivalent: Rhinoceros Viper and Boa Constrictor
One of the largest movie snakes out there, Unteka, has no clear species inspiration. The snake uses both venom and constriction and also has hornlike scales on its nose. The closest comparable real-life species are the rhinoceros viper (Bitis nasicornis) and the boa constrictor (Boa constrictor). Rhino vipers grow to only 4 feet long, while boa constrictors can reach 14 feet in length.
2. Boa (2001)
Also known as New Alcatraz, Boa is a direct-to-video horror sci-fi film starring, you guessed it, a giant man-eating snake. This particular movie monster is one of the largest movie snakes ever. The monster snake in Boa measures 80 feet long and spends its time killing all the residents and guards of an Antarctic prison. Boa’s prehistoric snake is the second-largest movie snake on our list.
Real Life Equivalent: Boa Constrictor
The snake in the movie Boa is based on the real-life boa constrictor. Boa constrictors aren’t the biggest snakes in the world, but they’re certainly respectable. The boa constrictor grows to a maximum length of 14 feet and may weigh over 50 pounds.
Boa constrictors are native to South America, where they spend much of their lives high in the trees. These snakes eat mainly rodents, like mice and rats, but won’t say no to lizards, frogs, monkeys, ocelots, or even wild pigs. Boa constrictors are non-venomous and give birth to live young.
1. Python (2000)
On the heels of Anaconda came the horror-comedy, made-for-TV film, Python. This film centers on a genetically engineered, 129-foot-long python that spits acid. Python has three sequels, each of which also features giant, man-eating snakes bent on consuming every human they come into contact with.
Real Life Equivalent: Reticulated Python
The real star of the movie Python is the monstrous, genetically mutated reticulated python. In real life, reticulated pythons really are enormous, but they’re not quite as big as the movie snakes. Reticulated pythons are the longest snakes in the world; they can grow up to 22 feet long and weigh over 100 pounds.
The reticulated python is native to Southeast Asia and lives as far west as India. It lives in a variety of habitats, including rainforests and grasslands, and spends a lot of time in the water. Like all giant snakes, the python kills by constriction. Young reticulated pythons eat rodents like rats and tree shrews. As they get bigger, their prey gets bigger too. Adult reticulated pythons can kill and eat wild pigs, deer, primates, and civets.
