Aquathlon (underwater wrestling), finswimming, freediving, spearfishing, sports diving, underwater football, underwater hockey, underwater ice hockey, underwater orienteering, underwater photography, underwater rugby, underwater target shooting, and underwater video are all examples of underwater sports. Some athletes even practice their skills in lakes or pools. Many activities can be done under water. Here are just a few: fish farming, marine engineering, underwater archaeology, underwater baling, underwater blasting, underwater welding, and wetsuit testing are all used in industrial applications. Climbing walls, swimming pools, and trampolines are all used in playgrounds. Scuba diving is used for recreational purposes such as finding treasure maps, taking pictures, and exploring caves. Underwater skating is a new sport that has been developed recently. It is similar to ordinary skating except that the user is submerged in water. The list of aquatic activities is very long.
