Whether they are on the silver screen or spotted on the news, anacondas are known to be scary reptiles. They’re excessively long, thick snakes with eyes situated on the top of their head to help them scope out prey while remaining underwater. These snakes are known for being constrictors rather than venomous snakes. They strike from the depths and choke the life out of their prey, taking down deer, crocodiles, and more. Today, we’re going to discover the largest anaconda ever and show you why that snake was truly a modern-day mythological creature!

How Big Was the Largest Anaconda?

The largest anaconda was 33 feet long, 3 feet across at its widest part, and weighed about 880lbs. This snake was discovered at a construction site in Brazil.  Unfortunately, it was either killed by the controlled explosion after which they found the snake or by construction workers after it emerged. Either way, humans killed the largest anaconda ever found.

That means the anaconda was never properly measured or recorded by any third-party agency that would have been able to lend credence to the claimed size. Although a video of the snake exists, we all know that videos can be altered and that perspectives can be confusing.

Other supposed record-breaking anacondas have been mentioned without proper citations or proof. One claim suggests that the longest, heaviest snake ever found was 27.7 feet long, had a girth of 3 feet, and weighed over 500lbs.

The chances are high that the largest anaconda has never really been captured or measured by people. When you consider that the green anaconda found in Brazil was merely stumbled upon by accident, it’s hard to say what lurks beneath the waters or in burrows in across the vast Amazon Riber basin.

How Large Are Most Anacondas?

Now that we have an idea of how large anacondas can get, we should take a look at the size of the average member of the species. The largest of all these variants is the green anaconda. The average green anaconda can reach about 20 feet in length and weigh 200-300lbs.

Several other species exist, including the yellow, Bolivian, and darkly-spotted anaconda. The female anacondas are larger than the males in most cases. As their names suggest, these different species vary in color, and they also vary in size.

Anacondas are hard to spot because they live in remote areas. The average size that has been found is much smaller than the largest one ever seen. Either the massive variants are exceedingly rare, or they are just good at staying away from humans.

Where Do Anacondas Live?

Anacondas are from South America. Specifically, they thrive in the lands east of the Andes mountains in places like Brazil, Colombia, Venezuela, Ecuador, Bolivia. These countries are common homes for these snakes, but they can be found in other places, too.

After all, anacondas are water boas, and they enjoy spending a lot of their time in the vast number of waterways that run throughout South America. They prefer to live in tropical rainforests, and they enjoy living in and around water. That means you can find them in slow-moving waters like rivers and streams.

When they’re not in the water, they will frequently hide in tall vegetation that allows them to ambush prey. Moreover, they enjoy staying out of sight of other predators seeking to make a meal of them.

As we said, these snakes are native to South America, but that is not the only place in which they can be found. In fact, green anacondas have made their way to the United States. They are one of the many invasive species that have come to the U.S., particularly in the Florida Everglades.  

Only a few of them have been found in the U.S. Yet, they could become like the Burmese python, an uncontrollable invasive species. Massive snakes have no natural predators in this area, so they can flourish with few threats to them. Human intervention is currently the only means of keeping these creatures in check.

Are Anacondas Venomous or Dangerous?

Anacondas are not venomous snakes, but they are still very dangerous. The average anaconda can reach sizes of 20 feet in length and weighs several hundred pounds. They are capable of taking down large creatures like deer and even jaguars in some cases.

Their method of attack isn’t unique, but it’s deadly. They are constrictors that belong to the boa family. These creatures often wait just below the water with the top-most portion of their heads sticking out. When they see the right type of prey come by, they lunge at them. The snakes use their teeth to hold them and begin the process of wrapping around them.

Once they have quelled the prey’s attempts at escape, they will constrict tighter and tighter until the animal is dead. Constriction is deadly on multiple levels, either causing strangulation or organ failure in their prey. Either way, the anaconda is hard to fend off, and the dead prey is swallowed whole.

Are Any Snakes Longer Than the Anaconda?

The green anaconda is often cited as the largest snake in the world because of its incredible length and body thickness. However, the record for the longest snake that was held in captivity and certified by a third party was a reticulated python.

Not only do they grow longer than anacondas on average, but they have reached verified lengths of over 25 feet. Furthermore, it’s believed that the maximum length of the reticulated python is 33 feet or longer.

Depending on whether we collectively believe that the green anacondas mentioned in this article, and they were not verified by proper authorities, the reticulated python might be a longer snake species. However, they are far thinner and lighter than most anacondas.

The anaconda is a massive reptile that could be the next major invasive snake species in the United States. Their presence in the vast wetlands of the Florida Everglades, a place bereft of predators, could lead to new, record-breaking snakes being discovered around the world.
