*cracks knuckles* alright, here we go. The infamous photo of the mysterious leucistic ball python swinging from a tree… To the best of my knowledge, that snake’s name is Faye (safe to click)!
She blongs to FurAffinity user Pull My Trigger (nothing super nsfw on the front page but tread with caution). All of these photos of Faye and Jake (the other snake she’s posing with, safe to click) have been taken from his gallery. If you go back a few pages in (again be cautious when clicking link), you can find all these photos, as well as some of his other snakes!!
EDIT: According to the artist, the image is so popular because a long time ago she won a contest on ball-pythons.net, she was also posted to Facebook, and because people love the image so much, they just took it and ran with it.
