ANSWERS TO CORRESPONDENCE: Geckos have remarkable adhesive qualities on their feet, enabling them to scale a variety of surfaces, including vertical walls and ceilings. It is mainly due to specific systems relating to their toes and intermolecular forces. Setae are tiny hair-like structures on the gecko's toe pads and are further divided into smaller structures called spatulae. These are powerful agents between molecules in close proximity, and Van der Waals forces, which are low attracting agents. The numerous spatulae on a surface help the gecko stick to the ground, allowing it to stick to the surface.
