Underwater diving

Underwater diving is the act of submerging one's own self underwater, with the intent of swimming underwater. It can be done to explore the depths of a river or other body of water, or it can be done for sport, such as in a swimming pool.

When diving into water, whether saltwater or freshwater, one can hold one's breath, or use Scuba equipment in shallow waters, or deep-sea diving gear and the ocean bottom.
