Underwater diving, also called underwater swimming, swimming done underwater either with a minimum of equipment, as in skin diving (free diving), or with a scuba (abbreviation of self-contained underwater-breathing apparatus) or an Aqua-Lung. Competitive underwater diving sports include spearfishing and underwater hockey, sometimes called “octopush.”

Underwater diving is as old as swimming and has been perpetuated into the present by pearl divers and sponge divers. Skin diving requires only a face mask or goggles, a short breathing tube (protruding from the mouth and kept above water), and flippers, or foot fins.
