A new study published in the Journal of the Royal Society Interface from a team of researchers (University of the Sunshine Coast, James Cook University, University of Queensland, Australia, and the University of Oxford) described how geckos living in humid areas manage to stay dry.

The researchers used a scanning electron microscope to take a closer look at the skin of box-patterned geckos (Lucasium steindachneri), which is how they discovered the dense microscopic spiny hairs that are also found in other species of geckos. The hairs trap air and the tips of the hair help gather water into droplets on the surface of the skin. Using slow-motion video recordings, they were able to see how the droplets formed and when large enough, fell off the skin.
