Scientists believe it is possible that the larger breeding females eat their smaller mating partners to survive the long, seven-month fast associated with pregnancy. There have been a few reports of cannibalism involving green anaconda females preying upon anaconda males. Size Averages 6 m (20 ft.) in length average diameter is 30 cm (12 in.) reportedly can grow in excess of 10 m (32.8 ft.) in length, though individuals at this length are rare and/or poorly documented the largest credibly documented specimen was reported to be 11.4 m (37.5 ft.) in length, though this 1944 figure is not innately accepted throughout the entire zoologic community newborn anacondas are 30-60 cm (12-24 in.) in length Weight Average of 148.5 kg (330 lbs.) Diet Anacondas feed on aquatic and amphibious animals, including mammals, fish, caiman, birds, ducks, and turtles. Spots with yellow-ochre centers run along the sides of its body. The green anaconda is typically dark green with oval black spots. The body is exceptionally stocky compared to other boas and extremely muscular. (Though the reticulated python - Python reticulatus - achieves similar lengths.) Their eyes and nostrils are located on top of the anaconda's large, narrow head - enabling it to breathe while the rest of its body is submerged. Their lifespan in the wild is about ten years.Scientific Classification Common Name green anaconda, common anaconda, water boa Kingdom Animalia Phylum Chordata Class Reptilia Order Squamata Family Boidae Genus Species Eunectes (good swimmer) murinus (mouse colored) murinusįast Facts Description Considering mass and length, the green anaconda is the largest snake in the world. Baby snakes are about 2 feet long when they are born and are almost immediately able to swim and hunt. Reproductionįemale anacondas retain their eggs and give birth to two to three dozen live young. Jaws attached by stretchy ligaments allow them to swallow their prey whole, no matter the size, and they can go weeks or months without food after a big meal. Anacondas are nonvenomous constrictors, coiling their muscular bodies around captured prey and squeezing until the animal asphyxiates. They reach their monumental size on a diet of wild pigs, deer, birds, turtles, capybara, caimans, and even jaguars. Their eyes and nasal openings are on top of their heads, allowing them to lay in wait for prey while remaining nearly completely submerged. They are cumbersome on land, but stealthy and sleek in the water. On Land and in WaterĪnacondas live in swamps, marshes, and slow-moving streams, mainly in the tropical rain forests of the Amazon and Orinoco basins. Other anaconda species, all from South America and all smaller than the green anaconda, are the yellow, dark-spotted, and Bolivian varieties. Females are significantly larger than males. Green anacondas can grow to more than 29 feet, weigh more than 550 pounds, and measure more than 12 inches in diameter. Learn how they maintain their massive size. The semiaquatic snakes weigh as much as 550 pounds, and can be as long as a school bus.
