 I'm Caroline Steele, and in this episode, we're tackling a question from listener Akello in Uganda. He wants to know how snakes climb trees and so fast. We've just seen one in action, a corn snake scaling a trunk at Telford Exotic Zoo in the UK. It used ridges on its belly to grip onto the tree's bark. Earlier in the show, we found a python in the swampy Florida Everglades. Annoyingly, she was underwater rather than up a tree, but we heard that she has a different way of climbing.
