When the going gets rough – studying the effect of surface roughness on the adhesive abilities of tree frogs [PDF]
, 2016 Tree frogs need to adhere to surfaces of various roughnesses in their natural habitats; these include bark, leaves and rocks. Rough surfaces can alter the effectiveness of their toe pads, due to factors such as a change of real contact area and abrasion
