Gobies have the pelvic fins fused creating a circular suction-cup.  This is used to cling firmly to hard surfaces to avoid being washed away by surge or climb up streambeds and waterfalls in the case of a few freshwater species.  Eggs of freshwater gobies are washed into the ocean to hatch before returning to any stream soon afterward.  Sleepers are very similar to gobies but lack fused pelvic fins.
