The ability to walk up walls helps animals because they can take advantage of places they are not familiar with. It also helps their habitats and resources. They can forage and hide from dangerous predators who eat them. The text states ¨What they discovered is that the proportion of sticky pads increases disproportionately with weight. For example mites, the smallest creatures tested, required about 200 times less viscous body-surface-area than the larger geckos. This they believe, limits the size of the climbing animals because at some point, the amount of sticky surface needed becomes impractical.¨ This shows that usually smaller insects and animals can climb walls to keep themselves agile and safe based on their weight and limit. The ability to walk on walls helps animals in many ways.
