Gecko feet diversity
Photomontage of living gecko feet showing a variety of forms. Gecko feet employ very small subdivided filaments to bond with their substrates at the molecular level using Van Der Waals forces. Every square millimeter of a geckos footpad contains about 14, 000 hairlike setae, each of which is tipped with between 100 and 1000 spatulae. If a single gecko had all spatuale engaged it could hypothetically hold a weight of 133kg. Their structure has inspired scientists such as Dr. Autumn Kellar to adapt the structure for robotic designs. Gecko feet have the property of being self-cleaning, very adhesive, but leaving no residue. The grip is so strong that geckos have to disengage their feet by curling their toes backwards, much like tape being peeled off glass. In this group the top right species is a ground Gecko which does not need sticky spatulae

EDITORS COMMENTS
This print showcases the remarkable diversity of gecko feet. Through a skillful photomontage, we are presented with a range of forms that highlight the intricate structures and adaptations found in these incredible creatures. Gecko feet possess an extraordinary ability to bond with their surroundings at the molecular level using Van Der Waals forces. The secret lies in their tiny subdivided filaments, which cover every square millimeter of their footpad. Astonishingly, each filament is adorned with hundreds to thousands of spatulae, resembling hairlike setae. The adhesive properties of gecko feet are truly awe-inspiring. If all spatulae were engaged simultaneously on a single gecko's foot, it could hypothetically support an astonishing weight of 133kg! This exceptional grip has not only fascinated scientists like Dr. Autumn Kellar but also inspired them to incorporate this unique structure into robotic designs. Moreover, gecko feet possess self-cleaning abilities and leave no residue behind due to their specialized design. To disengage from surfaces, geckos elegantly curl their toes backward akin to peeling tape off glass. In this diverse group depicted in the photo print, it is worth noting that the top right species represents a ground Gecko which does not rely on sticky spatulae for adhesion. Paul D. Stewart's stunning image captures both the beauty and scientific significance of gecko feet—showcasing evolution's ingenuity and offering inspiration for bioengineering advancements without mentioning any commercial use or affiliation with any company.
