The Biggest Snake: Green Anaconda (Eunectes murinus)

Reaching up to 30 feet, weighing up to 550 pounds, and growing up to a foot thick, the green anaconda is the world’s biggest snake. Anacondas live in the swamps, streams, and marshes of the Amazon basin in South America. Although slow on land, green anacondas are fast in water, and can stay almost completely underwater since their eyes and nose openings are on the tops of their heads. Anacondas eat everything from wild pigs and deer to jaguars and turtles. Since their jaws are attached to stretchy ligaments, the anaconda can swallow its prey whole, no matter how big. Although not officially evaluated yet by the IUCN, the green anaconda faces two main threats today. First is from deforestation, which has destroy much of the snake’s habitat. Second is the illegal international pet trade, which takes the green anaconda out of the wild and sells it to become someone’s pet.
