 Snakes climb trees, or scot, in three main ways, depending on the species. They use ridges on their bellies to grip onto tree bark. They use their tails to move from branch to branch like monkey bars. And big, muscly snakes, like our Burmese pythons in the Everglades, scale the tree by constricting it, extending their body, and then constricting it again. But for a heavy snake, that's a lot of work. So it's not often that you'll find a fully grown python in a tree.
