The 4 species of anaconda

The anacondas belong to the family of the jiboias, that is, they are constricting snakes (they kill their prey by choking them between their rings). Anacondas are the heaviest snakes in the world , and those in lengths just behind the reticulated python.

Cat Spraying No More is an excellent opportunity for the cat owners to learn about training the cat with a systematic approach. It helps in preventing the unwanted litter issues and other risks of bad feline behavior as well.

There are currently records of anacondas with 9 meters in length and 250 kg in weight. However, even older records speak of higher weights and measures.

If you continue reading this article of Animal Expert, you can discover the 4 species of anaconda that live in South America.

Anaconda-green egg Green juice

The anaconda-verde , Eunectes murinus , is the largest of the 4 anacondas living on the South American continent. Females are much larger (more than double) than males, in a very clear example of sexual dimorphism .

Its habitat is the tropical rivers of South America. It is an excellent swimmer that feeds on fish, birds, capybaras, tapirs, batfish and eventually jaguars, which in turn are also its main predators.

The anaconda-green color is dark green with black oval markers and ochres on the flanks. The belly is lighter and at the end of the tail there are yellow and black drawings that singulate each specimen.

Anaconda Boliviana or Sucuri-da-bolivia

The Bolivian anaconda , Eunectes beniensis , is similar in size and color to the anaconda-verde. However, the black spots are spaced and are larger than in the anaconda-green.

This species of sucuri lives only in the marshes and forests of the Bolivian humid lowlands, more concretely in the uninhabited departments of Pando and Beni. In these places there are marshes and flood savannahs without arboreal vegetation.

The usual prey of the Bolivian anaconda are the birds, large rodents, deer, peccaries and fish. This anaconda is not in danger of extinction.

Yellow Sucuri

The yellow succulent , Eunectes notaeus , is much smaller than the anaconda-verde and the Bolivian anaconda. Usually females do not exceed 4 meters, weighing 40 kg, although there are old records that ensure the existence of specimens of 7 meters.

The color differs from the other anacondas, it is a yellowish and green tone. However, the oval black spots and the belly of a womb of a paler tone is common to all of them.

The yellow sucurium feeds on wild pigs, birds, deer, rattlesnakes, capybaras and fish. Its habitat is the mangroves, streams, slow-flowing rivers and sandbanks with vegetation. The situation of yellow suckling is a threat as it is subject to poaching as food because of its flesh and skin.

A curiosity of this type of anaconda is that in the Indian towns it is frequent that they have an anaconda alive between them to get rid of the rodents. And hence the deduction that they are not afraid to be attacked by this great serpent.


The succulent , Eunectes deschauenseei , is smaller in size than the sucuri-da-bolivia and the sucuri-verde. Usually are over 4 meters long. Its color is yellowish with a profusion of black spots and stripes. Your belly is yellowish or creamy.

It is distributed by a wide region that includes the Brazilian northeast, French Guiana and Suriname. It inhabits the marshes, lakes and mangroves. There are examples from sea level up to 300 meters in altitude.

Their feeding is based on capybaras, peccary, birds, fish and exceptionally also on small caymans, since the small camões attack the anacondas to eat them.

The destruction of their habitation by farms and the killing by livestock keepers to protect their livestock have wiped out this species and are now in a state of threat.

Anacondas curiosities

  • Anacondas have a huge sexual dimorphism, since females measure and weigh more than twice as much as males.
  • In times of hunting shortage females eat males .
  • Anacondas are viviparous, that is, they do not lay eggs . They will give birth to small anacondas capable of hunting from day one.
  • Anacondas are great swimmers and the high disposition of their nostrils and eyes allows them to approach their prey with their body totally submerged. A vigorous bite of prey and a quick twisting around the body of the victim is its usual form of hunting. After killing the prey, they swallow it whole and once . Another form of hunting is to fall from a tree on its prey, which on many occasions kills by the tremendous blow because of its great weight.
