Scuba diving is a type of underwater swimming in which divers use special breathing equipment. The word ‘SCUBA’ stands for Self-Contained Underwater Breathing Apparatus.

Scuba divers wear full-body suits, called wet-suits, to protect against scrapes and cuts as well as to keep them warm in cool water. In order to lengthen the amount of time they can spend in the water, scuba divers attach oxygen tanks to their backs. These tanks allow divers to stay under water for up to 50 hours.

In 1943, French explorer Jacques Cousteau was the first person to test underwater breathing equipment.
