I have a 6-7 foot red tail boa, and he's pretty strong (like trying to pry his tail off a table leg when he doesn't wanna let go). And we used to have a burmese python. He got about 10 feet I think before we sold him. He got too big and heavy and it gets to be a hassle feeding him guinea pigs and bunnies. I cannot fathom the power of that snake in the picture. The article cited said he was 4 meters and 10 inches in diameter; I'm guessing he weighs over 200 pounds easily based on the snakes we've had. Absolutely amazing. And while he's not venomous, the bite is definitely still painful. My boa bit me in the hand once (completely my fault, not his) and though the teeth holes are real tiny, I had bruises on my hand from the strike force. Snakes are beautiful creatures, but they deserve respect.
