Instead of exerting a huge effort to stiffen their entire body to stand upright, tree-climbing snakes may concentrate their bending energy and muscle activity within a small region at their base, researchers report February 25 in the Journal of the Royal Society Interface. The team’s mathematical analysis suggests that pairing such a
