Gecko's have a natural swagger to their walk. This one's a chubby little guy. As this video reports, the angle of a surface - not its slipperiness - triggers when geckos turn on their superhero-like ability to walk on walls and ceilings, a new study finds. From the report: "Interestingly, the friction of a running surface seems to make no difference to whether geckos deploy their gripping mechanism or not. None of the Moorish geckos used their sticky pads on the flat planes even when they were slipping on the Plexiglas substrate and losing speed because of this. This observation led the researchers to conclude that geckos control their sticky toes by via a perception of their body’s orientation."
