Scuba divers are individuals who explore underwater environments using a self-contained underwater breathing apparatus, commonly known as scuba. This equipment allows them to breathe while submerged, enabling them to observe marine life, underwater landscapes, and shipwrecks. To become a scuba diver, one typically undergoes training and certification through organizations like PADI or NAUI. Divers learn essential skills, including how to manage their buoyancy, communicate underwater, and respond to emergencies, ensuring a safe and enjoyable experience while exploring the underwater world.
