 These are in the Everglades as well. Are they? Why weren't we looking for these ones, Hannah? They're much nicer than the 16-foot pythons. Like corn snakes, pythons have their hearts further up their body than, say, sea snakes, so they don't pass out when climbing trees either. But unlike corn snakes, they're too heavy to use concertina or lateral undulation to slither up a tree. Instead, they've got something else going for them.
