Females will sometimes cannibalize males, especially during breeding season. Adults are able to consume much larger animals, including deer, capybara, caimans and large birds. Juveniles tend to eat fish, birds and small mammals. They are opportunistic apex predators and eat a wide variety of prey.
Green anacondas have slow metabolisms, and with the exception of breeding females, only need to eat once every few weeks. Like most snakes, they can detach their jaw to swallow prey much larger then themselves, though they are careful to weigh the risk of injury with large prey. They use their strong jaws to capture their prey, then use their muscular bodies to suffocate the prey before swallowing it whole. As members of the boa family, green anacondas are nonvenomous constrictors. The longest venomous snake is the King Cobra.Like all snakes, green anacondas are carnivores. The longest Australian snake is the Scrub Python ( Morelia amethystina) which reached a length of 8.5 meters. A subspecies of this python is the Burmese Python.
The most popular ‘giant’ snake is the Indian Python ( Python molurus). The longest pet snake on record reached a length of 5.8 meters. One individual reached a length of 9.75 meters. The African Rock Python is the longest African snake. While it was common to find individuals with lengths up to 8 meters in the wild only a few decades ago, few wild creatures today exceed 5 to 6 meters. The longest python on record was a reticulated python that reached a length of 10.1 meters. Some biologists dispute this and consider the maximum length to be only 9 to 9.5 meters. The longest snake ever recorded was a 11.5 meter green anaconda from South America (Oliver 1958 and Gilmore and Murphy 1993). We quickly look at some of the record holders in various categories of snake ‘gigantism’. Most snakes are no larger than 1.25 meters. There is no way to define what a giant snake is except that it’s bigger than most snakes.
