Anaconda Snake Facts

Anacondas are mostly known for their incredibly large size. The length of an anaconda on average is 20 feet, and is among the largest snakes in the world! Some sources claim that there has been seen anacondas that are over 141 feet in length, extra extra large! Fortunately, most experts agree that these claims are not reliable, and that the largest anaconda captured to date is 28 feet.

There are four different types of anacondas, although people who refer to “the anaconda” usually are referring to the green anaconda, or Eunectes murinus, which is the largest of the four types in this group. The other three species that are officially called anacondas are the yellow anaconda, the darkly-spotted anaconda, and the Bolivian anaconda. We will talk about each species in the following section.

Green Anaconda

Green Anaconda

Green Anaconda (Eunectus murinus)

As I said before, the Eunectus murinus is the largest of the four spiecies of anacondas. Growing to an average length of about 22 feet, they are among the longest snake in the world! The reticulated python is considered the longest. However, the green anaconda is considered the heaviest, sometimes weighing a whopping 215 lb (97.5 kg).

Green anacondas are a dull olive green color with block spots throughout the snake’s body. In comparison to the body, its head is quite small, and it has a yellowish-orange stripe on both sides.

Yellow Anaconda

Yellow Anaconda

Yellow Anaconda (Eunectes notaeus

At 11-14 feet in average length, these snake are typically smaller than its close relative, the green anaconda. There is a common confusion between these two snakes. Because of this, it is hard to come up with an accurate statistic in the largest yellow anaconda ever. However, their have been confirmed findings of this snake with a length of 15 feet.

The reason for the confusion between these two species is that the yellow anaconda sometimes has a more of a yellowish-green body, which is similar to a green anaconda. However, they usually have a brighter yellow to golden color body. These snakes also have random dark splotches on their skin.

Darkly-Spotted Anaconda (Eunectes deschauenseei)

The darkly spotted anaconda is probably the rarest of the four types of anacondas. They are only found in French Guiana, Brazil and Guyana. Because of the rarity of this snake, there is not much known about the species.

In 1924, Rodolphe Meyer de Schauensee captured the first live specimen of the species. This is where they got the name "eunectes deschauenseei" (also called De Schauensee's Anaconda)

Eunectes beniensis

Bolivian Anaconda (Eunectes beniensis)

Not much is known about the Bolivian Anaconda either. Why? Because this species was discovered as recently as 2002! Like all anacondas, this species also has dark spots, but there's are a bit larger than others.

It is believed that these snakes can only grow up to 14 feet, although nobody can really say for sure because the lack of studies done on this new species. They are believed to inhabit only certain parts of Bolivia.
