Greens are probably the "least threatening" looking of all the giant snakes as while a reticulated python will look grumpily at you, green anacondas kinda look like oversized malfunctioning sand boas with their dorky eye placement. I used not to like the species too much but nowadays I find them quite cute, especially when they're smaller as very large females don't have the most appealing facial structure, and their eyes are hard to distinguish detail in. Interestingly though their pupils are vertical slits but look kinda hourglass shaped. I wonder why that is.
