What is scuba meaning?

Scuba is an acronym for "Self-Contained Underwater Breathing Apparatus". It refers to the equipment and techniques used in recreational and professional diving to allow people to breathe underwater. Scuba diving can be performed in shallow or deep waters, and involves the use of tanks filled with compressed air, as well as other equipment such as fins, masks, and wetsuits. Scuba diving provides an opportunity to explore underwater environments and observe marine life, but requires proper training and certification to ensure safety.
