Underwater diving is the practice of descending below the water's surface to conduct underwater activities. In ambient pressure diving, the diver is exposed to the pressure of the surrounding water, and uses breathing apparatus for scuba diving or surface supplied diving, or when freediving, will breath-hold. The saturation diving technique reduces the risk of decompression sickness after long duration deep dives.
Your pet slider (Trachemys scripta ssp.) or painted turtle (Chrysemys picta) will frequently swim underwater for long periods of time -- certainly longer than you could hold your breath. At night, when they are inactive, many pet turtles sleep underwater, surfacing only a few times to grab several quick breaths.
