When water is dropped on a hydrophobic surface, rather than spread out over the object, the water forms droplets. Some plants, animals, and insects have hydrophobic surfaces and will repel water ...
The interactions between the gecko's feet and the climbing surface are stronger than simple surface area effects. On its feet, the gecko has many microscopic hairs, or setae (singular seta), that increase the Van der Waals forces - the distance-dependent attraction between atoms or molecules - between its feet and the surface.

This has been observed in geckos and spiders but also in the smooth adhesive pads of ants, bush-crickets and cockroaches. [3] Adhesive hairs of geckos are non-symmetrical and feature distally pointing setae and spatulae that are able to generate increased friction and adhesion when aligned with a proximal pull. [ 3 ]
Karamoja dwarf geckos are considered “large,” reaching about 3 inches in size. They have “slender” bodies, “rounded” snouts and several “chevrons” on their throats. These geckos ...
Like other reptiles, geckos are ectothermic, [15] producing very little metabolic heat. Essentially, a gecko's body temperature is dependent on its environment. Also, to accomplish their main functions; such as locomotion, feeding, reproduction, etc., geckos must have a relatively elevated temperature.
Pachydactylus rangei, the Namib sand gecko [4] or Namib web-footed gecko, is a species of small lizard in the family Gekkonidae.It inhabits the arid areas of Angola, Namibia, and South Africa, and was first described in 1908 by Swedish zoologist Lars Gabriel Andersson, [3] who named it after its finder, German geologist Dr. Paul Range.
