A large family of benthic fishes of marine and freshwater environments with fused pelvic fins forming a circular suction-cup.  This structure is used to cling firmly to hard surfaces to avoid being washed away by surge or move upstream along river beds and waterfalls.  Eggs of freshwater gobies hatch in the ocean and young return to freshwater soon after.  Sleepers, sometimes assigned to the Family Eleotridae, are gobies with unfused pelvic fins.
