Round gobies lack a swim bladder, and movement is characterized by an
alternating pattern of bottom rests and short swim bursts. Unlike native
sculpins and darters, the gobies have fused pelvic fins that act like a
suction cup. This gives the gobies a stronger ability to cling to rocks
in faster currents and a migratory advantage for moving upstream against
the current.
