BP's are terrestrial snakes but occasionally climb. i've seen plenty of pix and posts of BP's climbing branches in their enclosures. but these are 1-2 feet climbs on branches and perches and not full size tree climbs. that said, i was just scrolling through the forum and there's a new DIY jungle gym thread in the Morelia (arboreal python) forum - http://ball-pythons.net/forums/showt...ungle-Gym-help!
