But less well understood is how these reptiles cling to wet surfaces, which are common in their rainy tropical habitats.
The answer, a new study reveals, is that a gecko’s sticky toes enable the animal to walk across wet surfaces that don’t get uniformly wet, like waxy leavesâ€”but not on easily wettable surfaces, like glass.
This is “an interesting question that the field of gecko biology hasn’t quite looked at before” now, Â said study leader Alyssa Stark, a biologist at the University of Akron in Ohio.
Why does it matter? Because figuring out a gecko’s grip could help people make adhesives that will work in water, Stark said.
Imagine, for instance, putting a Band-Aid on underwater and having it stick just as well as it would on land.
