Anaconda Species Overview
Anacondas are some of the heftiest and most intriguing snakes cruising our planet. Here, we’ll chat about two main types: the green anaconda and the yellow anaconda.
Green Anaconda Characteristics
Meet the green anaconda (Eunectes murinus), the heavyweight champ of snakes. It holds bragging rights as the heaviest snake and plays runner-up for length behind the reticulated python. The ladies of this species are the larger of the two, averaging around 32 kg (70 lb), while the fellas are much lighter at about 7 kg (15 lb). These slippery giants can stretch up to 9 meters in length and can tip the scales at a whopping 250 kg.
| Characteristic | Details |
|---|---|
| Scientific Name | Eunectes murinus |
| Maximum Length | Up to 9 meters (30 feet) |
| Maximum Weight | Up to 250 kg (550 pounds) |
| Female Average Weight | 32 kg (70 pounds) |
| Male Average Weight | 7 kg (15 pounds) |

Yellow Anaconda Overview
Now, the yellow anaconda (Eunectes notaeus) is like the green’s bantamweight sibling. Smaller than its cousin, the yellow anaconda tops off at around 4.6 meters (15 feet), with females usually taking the title for longest. Even though it’s the little sibling, it’s still a sizable reptile.
| Characteristic | Details |
|---|---|
| Scientific Name | Eunectes notaeus |
| Maximum Length | Up to 4.6 meters (15 feet) |
| Female Average Length | Generally longer than males |
Learning about the similarities and differences between these snakes opens a world of wonder for anyone curious about these impressive creatures. Delving into their unique features, you’ll find a new appreciation for the diversity among anacondas.

Taxonomic Implications
Shaking Up Anaconda Species
The family tree of anacondas just got a little messier. Folks have been chattering about the green and yellow anacondas—those slippery critters—because some fresh research has stirred the pot on their classification. A newbie in the green anaconda clan, named Eunectes akayima, just made its big debut, sparking a do-over on the usual sorting (MDPI). Also, some brainy types like Rivas and others thought it best to lump Eunectes deschauenseei and Eunectes beniensis under the yellow anaconda’s wing (Eunectes notaeus). Now, we’re looking at three main anaconda types.
| Species Name | Common Name | Comments |
|---|---|---|
| Eunectes murinus | Green Anaconda | By far the most studied |
| Eunectes notaeus | Yellow Anaconda | Now includes E. deschauenseei and E. beniensis |
| Eunectes akayima | New Green Anaconda | Just got discovered |
Fresh Finds in Anaconda Taxonomy
We’re seeing a bit of a shake-up in how we view green and yellow anacondas. The green one (Eunectes murinus) was already hogging the spotlight, especially when it comes to its flirting style. Meanwhile, the yellow anaconda (Eunectes notaeus) might not get as much airtime, but it’s still a key player when we’re sussing out the whole Eunectes lineup. As for the less famous Eunectes deschauenseei and Eunectes beniensis, they’ve found a new home under Eunectes notaeus because, well, they kinda look alike and hang out in the same ‘hood (Wikipedia).
Now, hold on to your hats—Eunectes akayima is the new kid on the block, and it’s forcing a rethink of how these sneaky snakes stack up against each other (MDPI). Getting a handle on these shifts is key if you wanna appreciate the wild variety and family roots of the Eunectes gang.

Size and Physical Features
Getting a grip on anacondas’ size and looks shows how different the big green anaconda is from the smaller yellow one. These details are key to figuring out how each makes a living in their neck of the woods.
Green Anaconda Size
Meet the green anaconda, or Eunectes murinus, one of the biggest snakes in the world. These guys can stretch up to a whopping 9 meters (29.5 feet) and tip the scales at 250 kg (550 lbs). But usually, they don’t go beyond 5 meters. There’s a big difference between the ladies and gents here, with females growing much larger. Your average female weighs in at about 32 kg (70 lbs), while the males are much daintier, around 7 kg (15 lbs) (Wikipedia).
| Metric | Male Green Anaconda | Female Green Anaconda |
|---|---|---|
| Average Length | 4-5 meters | 7-9 meters |
| Average Weight | 7 kg | 32 kg |
| Maximum Length | 5 meters | 9 meters |

Yellow Anaconda Appearance
Here comes the yellow anaconda, or Eunectes notaeus, also known as the Paraguayan anaconda. It’s the runt of the litter compared to its green sibling, with females maxing out around 4.4-4.6 meters (Encyclopedia Britannica).
These snakes sport a unique fashion statement with their yellowish-green scales lined with brown or blackish patterns that help them go undercover in water and thick jungle (Animal Diversity Web). Their tricky coloration is perfect for both ambush hunting and steering clear of hungry eyes.
| Metric | Yellow Anaconda |
|---|---|
| Maximum Length | 4.6 meters |
| Average Weight | 25-35 kg |
| Coloration | Yellowish-green with brown/black bands and spots |
By sizing up the green and yellow anacondas, it’s easier to see what sets them apart. This helps understand their habits, love life, and place in nature. For more on these slick serpents, have a look at anaconda habitat and how to identify an anaconda.
Behavior and Reproduction
Mating Systems
Green and yellow anacondas like to keep things interesting (and a little chaotic) when it comes to mating. These snakes play the field with a little something called a polyandrous mating system. Imagine one lady anaconda being wooed by several male suitors. They form what folks call a “breeding ball” — a writhing heap of snakes vying for the female’s attention, and it can spin out for weeks! The female uses sneaky pheromones to call the boys over, which leads to lots of snake tussling over who gets the girl (Wikipedia).
Here’s how the whole snake romance goes down:
| Feature | Description |
|---|---|
| Mating System | Multiple males for one female |
| Mating Season | When it’s dry, they try |
| Method | Snake pile (breeding ball) |
| Duration | A few weeks of snake wooing |

Reproductive Behaviors
Watching these snakes handle baby-making is like seeing a natural survivalist in action. Green and yellow anacondas keep their little ones safe by being ovoviviparous, basically meaning the lady snakes keep the eggs inside until they’re ready to bring live, slithering babies into the world. No risky egg-laying here; by holding onto their embryos for up to seven months, mamá snake shields them from danger and hungry critters (Encyclopedia Britannica).
Here’s how an anaconda family gets started:
| Feature | Description |
|---|---|
| Gestation Period | Tops out at 7 months |
| Birth | Live and wriggly |
| Number of Offspring | Around 20 to 40 snakelets |
Their approach is perfect for their challenging and often harsh habitats. Learn more about these snake parenting strategies at anaconda reproduction.

Threats to Anacondas
Even with the “Least Concern” status, anacondas aren’t in the clear. Here are some curveballs they’re dodging:
-
Habitat Loss: With forests getting chopped and land gobbled for development, anacondas’ stomping grounds in the Amazon are shrinking.
-
Hunting and Poaching: These big snakes sometimes find themselves on a shopping list for their skin, often ending up in trendy fashion items. Others may hunt them out of fear or to protect livestock.
-
Environmental Pollution: Polluted waterways, their homes, aren’t doing them any favors. Pesticides and other nasty stuff can be troublesome.
-
Climate Change: Changing weather messes with their homes and food supply, making survival a bit trickier than before.
