Green anacondas live primarily along rivers and in swampy areas with lots of water and heavy vegetation so are less common around human habitations.įamily Boidae contains 57 additional species found in North and South America, Africa, Madagascar, Europe, and the Pacific region. They are slightly shorter in length but thicker in diameter compared to reticulated pythons, so can weigh almost half again as much. Native to the Amazon rainforest and found throughout South America east of the Andes, female adult green anacondas can weigh up to 176 pounds (80 kg) (Wikipedia 2023) males are smaller and lighter. Snakes classified within family Boidae are the “boas” and includes the species recognized as the world’s heaviest snake, the green anaconda ( Eunectes murinus). Other well-known pythons include the Burmese python ( Python molurus bivittatus), Northern African python ( Python sebae), and ball python ( Python regius). The longest venomous snake is the King Cobra.Family Pythonidae contains 39 additional species seven of which are also found in Asia, 4 in Africa, and 28 in Papua New Guinea and Australia (Halliday and Adler 2015). 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.
