According to The Sun, the head of this anaconda is as big as an adult human's head. "You can see in the video the biggest anaconda I've ever seen, as thick as a car tire," said Vonk. Before this anaconda was discovered, there was a species of green anaconda found in the rainforest. As seen in the uploaded video, Vonk, still wearing a blue shirt and long pants, appears relaxed swimming alongside the anaconda at the bottom of the river.

"Although they may appear similar to other Green Anaconda species at first glance, the genetic difference between the two is as much as 5.5 percent, and that is significant. 'So, we named this green anaconda with the Latin name, Eunectes akayima, Northern Green Anaconda,' said Vonk."
