Wreck diving is a type of scuba diving that involves exploring sunken ships, aircraft, or other structures. Divers often seek out these sites to learn about maritime history, marine life, and underwater ecosystems. Wrecks can provide unique habitats for various species, making them popular spots for both recreational and technical divers. Safety is crucial in wreck diving, as these sites can present hazards like sharp metal, entanglement risks, and limited visibility. Divers should be trained and experienced, often using specialized equipment. Popular wreck diving locations include the Great Lakes, Scapa Flow, and the Red Sea.
