Gecko's foot. Close-up of the underside of the foot of a common gecko, Tarentola mauritanica. The undersides of the toes are composed of many lamellate cushions (pads) as seen. These tiny supple plates of skin are equipped with a network of microscopic hairs, millions on the sole of each foot. It has been found that these specialised hairs with tufts at the tip produce electrical attractions. It is the combined attraction of the weak electrical forces (van der Waals forces) that allow the gecko to stick to virtually any surface, even polished glass or walking upside down. Photographed in Southern France.
