I recently purchased this adult male Anaconda off Kingsnake's Classifieds, where he was listed as a Yellow. He looks a bit different from all the Yellows I've ever seen, though. His blotches are solid jet black, with no lightening in the centers, and his head is much darker than any I've seen, almost reminding me of the head pattern on My African Rock Pythons. Is this guy just a somewhat-aberrant Eunectes notaeus, or what?
He is a very docile snake, in spite of his size and the rep that Anacondas have. Due to his size, it's hard to get a photo of the entire snake.
