Secret Found For Amazing Clingfish Suction Power
by Joseph Castro
Using tiny hairs similar to those on gecko feet, clingfish are able to strongly and equally adhere to surfaces with a broad range of roughness, new research shows. The fish’s suction powers easily outperform manmade suction cups, scientists say, adding that mimicking their design could lead to a new class of suction devices.
The northern clingfish (Gobiesox maeandricus) is a species of salt-water fish native to the Pacific Coast of North America. The fish live in rocky intertidal environments, where strong waves and currents threaten to toss them about. To survive in this turbulent setting, the fish has evolved an adhesion disc on its belly, which takes up about 25 percent of its underside. Using the disc, the fish can achieve a death-grip on a variety of surfaces…
