The northern clingfish, Gobiesox maeandricus, is able to adhere to slippery, fouled and irregular surfaces in the marine intertidal environment. The fish can adhere equally well to surfaces with a broad range of surface roughness, from the finest sandpaper to textures suitable for removing finish from flooring. The fishes outperform man-made suction cups, which only adhere to the smoothest surfaces. This adhesion mechanism relies on hierarchically structured microvilli, which interdigitate with the projections of rugose surfaces. This points to a possible biomimetic solution to the problem of reversibly adhering to irregular, submerged surfaces.
