Dancing Gecko Lizard

Adhesion Ability
The toes of the gecko have a special adaptation that allows them to adhere to most surfaces without the use of liquids or surface tension. The spatula tipped setae on gecko footpads allow attractive forces called capillary forces to arise between the adhesive setae and the surface.
One study suggested that capillary adhesion might play a role, but that hypothesis has been rejected by more recent studies.
These van der Waals interactions involve no fluids; in theory, a boot made of synthetic setae would adhere as easily to the surface of the International Space Station as it would to a living room wall, although adhesion varies with humidity. The setae on the feet of geckos are also self cleaning and will usually remove any clogging dirt within a few steps. Teflon, which has very low van der Waals forces, is more difficult for geckos to adhere to than many other surfaces.
