Researchers know the secret to geckos’ ability to walk on the ceiling: their hairy toes. But how do they use their five toes per foot to adjust to gravity when running horizontally along walls. At UC Berkeley, biologists used high-speed cameras to record how geckos orient their toes with shifting weight, especially when encountering slippery or rough patches, and found a remarkable ability to adjust toe orientation to stick and peel while running full speed.
