Science Nation: Waterfall-Climbing Fish Performs Evolutionary Feat

Fish with a suction cup at the mouth area holding on to a nearly vertical surface. Caption: and suction cup that holds to the surface.

The species of Goby fish, Sicyopterus stimpsoni, also known as the inching climber, thrives in the waters off Hawaii. 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. With support from the National Science Foundation, 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. Part of the National Science Foundation Series “Science Nation.”
