To reach the safe haven of its freshwater spawning area, this Goby must scale a waterfall, or at least the rock behind it, using suction cups on its body.Typically no bigger than a few inches, it makes its way up the rock, hundreds of feet high. Comparatively speaking, a human being would have to climb Mount Everest three times in order to compete with the Inching climber, according to St. Cloud State University biologist Heiko Schoenfuss.With support from the National Science Foundation, he and other scientists at St. Cloud and Clemson Universities study these extraordinary fish to better understand how they've adapted and evolved in order to achieve such vertical feats. The challenge in this case is climbing waterfalls, but Heiko says their findings can be extrapolated to other species, and whether it's human-induced selective pressure, pollution or warming waters, we can learn about how adaptation occurs over long and short periods of time.\n
