This may help it to survive pregnancy, since during the gestation period the female will not feed from 6 to 10 months, in order to survive the dry season, they shelter underground in caves or the mud in river banks, they may also seek out deeper water. The snakes may stay together up to a month during which the female may mate multiple times.Īfter mating the female snake may eat one or more of its male counterparts. These snakes are solitary until the mating season, during this period the green anaconda clusters in a breeding ball that may consist of 2 up to 13 males coiled around one female snake. The green anaconda reproduces sexually and uses internal fertilization, the species takes around 6 years to reach sexual maturity. The courtship and mating season typically occurs between mid-February to late May, the female lays down a pheromone trail, which attracts the males. The green anaconda has a very slow digestive system, it will often take days or weeks for it to digest food, after a meal the snake may not eat again for weeks or months. They are capable of unhinging their jaws to swallow their prey whole, even big animal like deer. The snakes use its teeth and powerful jaws to hold onto the prey while their massive and extremely muscular body wrap around the prey to suffocate or drown it. They also attack and eat livestock or pets like sheep and dogs and in rare cases, these large constrictors are also known to attack humans. The larger green anaconda snakes prey upon animals as big as deer, capybara (a giant rodent), tapirs and even full-grown spectacled caimans and jaguars, they are also cannibalistic with females often feeding on the smaller male green anacondas. The green anaconda feeds on a variety of prey according to their size, with smaller specimens eating mainly fish like piranhas and other small vertebrates like turtles and birds, they even climb trees to raid bird nests. The species average lifespan is about 10 years but may exceed 30 years. The species is known by other common names including anaconda, common anaconda, and water boa, and also several local names like the Spanish term mata toro (it means literally "bull killer") or sucuri in the Tupi language among many others. Its scientific name Eunectes murinus derives from the Greek word "ευνήκτης" meaning "good swimmer" and the Latin "murinus" meaning "of mice" since it was thought they preyed on mice. Their head is relatively small sized when compared to the thick body with distinctive orange-yellow striping on the sides. The green anaconda coloring is typically an olive green background with oval black spots running down the back and smaller oval spots with yellow centers along the sides, providing excellent camouflage. They have the eyes and nostrils located on top of their heads enabling it to breathe and see while they remain nearly completely submerged, allowing the anaconda to lay in wait for their unsuspecting prey. ![]() These massive snakes are clumsy on land because of their sheer weight, but they are sleek and stealthy when in the water. The green anaconda also exhibits the greatest sexual dimorphism between the sexes of any terrestrial vertebrate, females dwarf males in length and are almost 5 times heavier. It's the considered the heaviest snake and only the reticulated python grows slightly longer than the green anaconda but it weighs much less, due to the enormous girth of the anaconda making it almost twice as heavy. Green anacondas grow as long as 29 feet, with a girth of 12 inches (30 centimeters) in diameter and weigh as much as 550 pounds, this undoubtedly one of the world’s largest snakes and much larger than their cousin the yellow anaconda ( Eunectes notaeus). ![]() Either in the seasonally flooded savanna, such as Llanos grasslands of Colombia and Venezuela or in the rivers of the vast Amazon and Orinoco basins. This is a semi-aquatic non-venomous snake species, the green anaconda is typically found in swamps, marshes and slow-moving rivers and streams. They are also found on the island of Trinidad off the Venezuelan north-east coast. ![]() The green anaconda ( Eunectes murinus) lives throughout the tropical South America, mostly found east of the Andes through the Amazon and Orinoco river basins, as well as in Colombia, Venezuela, Brazil, the Northern regions of Bolivia, north-east Peru, Guyana and French Guiana.
