The new species, described in the journal Diversity, diverged from the previously known southern green anaconda about 10 million years ago, differing genetically from it by 5.5 per cent.
The green anaconda is the world's heaviest and one of the world's longest snakes, reaching a length of up to 5.21 m (17 ft 1 in) long. [11] More typical mature specimens reportedly can range up to 5 m (16 ft 5 in), with adult females, with a mean length of about 4.6 m (15 ft 1 in), being generally much larger than the males, which average ...

A video shared online shows the scale of these 20-foot-long (6.1-meter-long) reptiles as one of the researchers, Dutch biologist Freek Vonk, swims alongside a giant 200-kilo (441-pound) specimen.
Fossils of what may be the largest snake ever, the extinct boa Titanoboa were found in coal mines in Colombia. It has been estimated to reach a length of 12.8 m (42 ft) and weighed about 1,135 kg (2,502 lb).
