The green anaconda can be found in tropical South America, east of the Andes in Amazon and Orinoco basins, and in Guianas, north to Trinidad, where they live in tropical rainforests, savannas, grasslands, scrub forests and deciduous forests. Life span is 15-20 years in the wild up to 30 years under human care. The center of the body may be up to 12 inches in diameter. It is the heaviest snake in the world, weighing up to 550 lbs., and measuring up to 29 feet.

Its body is extremely stocky compared to other constrictors and it is extremely muscular. The eyes and nostrils are on top of the head so the snake may be submerged while hunting. The head is large and narrow and is not distinct from the neck. The pattern of the scales found along the black and yellow underside of the lower tail is unique to each snake and may be used for identification. There are similar spots with a yellow-ochre center along the side of the body. This large snake is dark green with alternating oval black spots. The early Spanish settlers referred to this snake as “matatoro” or “bull killer.” Physical Characteristics Both snakes are excellent swimmers and are two of the largest snakes in the world.

A similar Tamil word for anaconda is “anaikolra” which means “elephant killer.” No one is sure how this name came to represent a South American snake, unless these two snakes - anaconda and python - were mistaken for the same species. The name “anaconda” comes from the Asian Indian Sinhalese language, and originally referred to the reticulated python. South American Tropical Rainforest and Aviary Fascinating Facts
