![]() It grabs its victim and pulls it underwater, drowning the prey. ![]() The extremely muscular anaconda is a constrictor and is not venomous however, it still has teeth and powerful jaws that it utilizes to clench onto its prey. Its eyes and nostrils are positioned on the top of the head, enabling the anaconda to breathe and to see its prey while its stocky body lies submerged under water. The anaconda has a large head and a thick neck. It lies submerged in the water, with only a small part of its head above the surface, waiting for any suitable prey, or it establishes itself upon the branches of a tree which overhangs the water or the track of game. The anaconda combines an arboreal with an aquatic life and is active mostly during the night. The belly is whitish, spotted with black spots. The general colour is dark olive- brown, with large oval black spots arranged in two alternating rows along the back, and with smaller white-eyed spots along the sides. The Bolivian Anaconda ( Eunectes beniensis) found in Bolivia, which was only identified in 2002 by Lutz Dirksen, and is still being studied.Įunectes murinus (formerly called Boa murina) differs from Boa by the snout being covered with shields instead of small scales, the inner of the three nasal shields being in contact with that of the other side.The Dark-Spotted or Deschauense's Anaconda ( Eunectes deschauenseei) found in northeast Brazil.These live further south in Bolivia, Paraguay, Uruguay, western Brazil, and northeast Argentina. The Yellow Anaconda ( Eunectes notaeus), which reaches a relatively smaller average adult length of 3 metres (9.8 feet).Jesus Rivas.Īn anaconda snake on a tree branch, waiting for its prey above the river, Amazon basin, Peru. Although charismatic, very little information was known about the anacondas until 1992 when the first study (and so far the only) was made on the field biology of this species in the Venezuelan llanos by Dr. These are found mainly in northern South America, in Venezuela, Colombia, Brazil, Ecuador, northern Bolivia, northeast Peru, Guyana, and the Nariva Swamp in Trinidad where they are known as "Huille" (pronounced Wheel). ![]() Females are larger than males, averaging 22-26 feet and 12-16 feet respectively. It can weigh 250 kg (551 pounds) and have a diameter of more than 30 cm (11.8 inches). In fact, it is the heaviest snake species in existence. Although shorter than the longest recorded species, the Reticulated Python, it is considerably heavier. The Green Anaconda ( Eunectes murinus, from the Greek "ευνήκτης, eunectes", meaning "good swimmer"), which has been reported at over 10 meters (32.8 feet) in length (although most are considerably smaller).It is unclear how the name originated so far from the snake's native habitat it is likely due to its vague similarity to the large Asian pythons. There are two possible origins for the word 'anaconda': It is perhaps an alteration of the Sinhalese word 'henakanday', meaning 'whip snake', or alternatively, the Tamil word 'anaikondran', which means 'elephant killer', as early Spanish settlers in South America referred to the anaconda as 'matatoro', or 'bull killer'. The Yellow Anaconda can be found as far south as Argentina. Anacondas (local names: Jibóia and Sucuri) are four species of aquatic boa inhabiting the swamps and rivers of the dense forests of tropical South America.
