Quck answer
The anaconda is one of the largest and most powerful snakes in the world, found in the watery habitats of South America. They can grow up to 30 feet long and weigh over 500 pounds, making them apex predators in their environment. Anacondas are semi-aquatic and spend most of their time in or near water, where they hunt for prey such as fish, birds, and mammals. Despite their fearsome reputation, anacondas are not aggressive towards humans and typically avoid confrontation. However, their size and strength make them a formidable creature to encounter in the wild.

All snakes are capable of swimming, although some are more adept than others. The green anaconda (Eunectes murinus) is one of the most powerful species that exists today, and it is perfectly suited to its habitat in the rivers and swamplands of Amazonia. Its eyes face upwards, like those of a crocodile, which allows it to scan the muddy banks for prey, while its muscular coils remain hidden beneath the water’s surface.
That’s why anacondas are often referred to as “water boas.” This is a fitting name, except they don’t have any feet. Science recognizes four species of anaconda, including the green anaconda (Eunectes murinus), the yellow anaconda (Eunectes notaeus), the darkly spotted anaconda (Eunectes deschauenseei), and the Bolivian anaconda (Eunectes beniensis). All four belong to the boa family and are native to South America.
By every measure, the green anaconda stands out. Not only is it the largest member of the Eunectes quartet, but it’s also arguably the largest snake in the world. However, determining the animal’s maximum size is a challenge.
The Long and Short of It
Folklore in the Amazon region is full of stories about giant monster snakes measuring 60 to 100 feet (18.2 to 30.4 meters) long. According to the fossil record, a colossal serpent did exist on the continent 60 million years ago. It was called Titanoboa, and it’s believed to have grown up to 50 feet (15.2 meters) in length and weighed around 2.5 tons (2.26 metric tons).
Green anacondas, on the other hand, are nowhere near that size. The typical length for this species is about 19.7 feet (6 meters). Males, who are smaller than females, rarely exceed 13.1 feet (4 meters). The largest ever reliably documented anaconda was 27.2 feet (8.3 meters) long.
Nevertheless, rumors that anacondas can grow two or three times larger persist. Some claims are based on enormous skins taken from dead snakes. However, these are easily distorted, even unintentionally.
In 1978, herpetologist William H. Lamar proved this point when he killed a wild anaconda of ample size. The freshly killed snake was a respectable 24.58 feet (or 7.49 meters) long. Lamar then measured the snake’s skin after he skinned it. Despite his best efforts, he couldn’t avoid stretching out the skin, which gave it a post-mortem length of 34.58 feet (10.54 meters).
The largest and heaviest Eunectes murinus can weigh 440 pounds (200 kilograms) or more. As a species, the green anaconda is considered to be the world’s heaviest snake but not necessarily the longest. Lengthwise, the Asian reticulated python probably holds that title. According to “The New Encyclopedia of Snakes” by Chris Mattison, there have been “several authenticated reports” of large “retics” measuring about 28 feet (8.5 meters) from head to tail.
Hunting Habits
Anacondas prefer slow-moving rivers, muddy swamps, and seasonally flooded plains. They rarely venture far from flowing or standing water, although some species may choose to hunt in forests on occasion.
Anacondas have eyes situated on the tops of their heads, and their nostrils are also located in this region. This allows them to see and smell what’s happening above the water’s surface while they swim or soak. This makes it much easier for these semiaquatic reptiles to capture their prey.
Anacondas are known for their ability to kill their prey through constriction. They seize their victim with their jaws before immobilizing them with tightly wrapped coils. Contrary to previous beliefs, new research shows that the real cause of death for the victim is cardiac arrest, not strangulation. Wild anacondas feed on a variety of prey such as fish, lizards, birds, bird eggs, other snakes, carrion, and mammals. They have been known to swallow up caimans and capybaras, which are the largest rodents in the world.
While anacondas have never been confirmed to have killed and eaten humans, they will defend themselves if cornered. They are not venomous, but they can inflict deep bite wounds and secrete a foul-smelling liquid when distressed. Anacondas are not as popular as other snakes among reptile-keepers because they require specific enclosures, high humidity levels, and large water dishes. In 2012, the U.S. Fish and Wildlife Service banned the importation and interstate transport of the yellow anaconda due to the potential threat it poses to native species.
During the breeding season, several male anacondas may attempt to mate with a single female. This results in a “breeding ball,” which sees as many as 13 males all squirming around a mother-to-be. They give birth to live young, with litters containing anywhere from four to 82 baby snakes. Interestingly, they can reproduce asexually through parthenogenesis, as observed in Komodo dragons and Burmese pythons.
Green anacondas have no problem with cannibalism, as herpetologist Jesus Rivas noted four separate cases of a large female anaconda eating smaller anacondas, at least two of which were males.
FAQ
What is an anaconda?
An anaconda is a large, non-venomous snake found in South America. It is one of the world’s largest snakes, growing up to 30 feet long and weighing up to 550 pounds.
What do anacondas eat?
Anacondas are carnivores, and they primarily eat fish, birds, mammals, and reptiles. They are known to eat large prey, such as deer and caimans. Anacondas kill their prey by constriction, suffocating their prey until it dies.
Where do anacondas live?
Anacondas are found in the swamps and rivers of South America, primarily in the Amazon and Orinoco basins. They are excellent swimmers and can stay underwater for up to 10 minutes.
Are anacondas dangerous to humans?
Anacondas are not typically a threat to humans, as they prefer to avoid contact with people. However, if provoked or threatened, they will defend themselves. Anacondas are not venomous, but their powerful jaws and muscular bodies can cause serious injury or death.
How do anacondas reproduce?
Female anacondas give birth to live young, which can number up to 50 in a single litter. The young are born fully formed and can swim and hunt on their own shortly after birth.
What is the lifespan of an anaconda?
The lifespan of an anaconda in the wild is not well known, but they can live up to 30 years in captivity.
What is the biggest anaconda ever recorded?
The largest anaconda ever recorded was 28 feet long and weighed 550 pounds. It was found in the Amazon rainforest in 2014.
Are anacondas endangered?
Anacondas are not currently considered endangered, but they are threatened by habitat destruction and hunting for their skin and meat. It is important to protect their habitats to ensure their survival.
