Why is it important for divers to avoid touching marine life on wrecks?

Touching marine life on wrecks can pose a significant risk to divers, primarily due to potential injuries from stings or bites. Many marine organisms, such as jellyfish, anemones, and certain fish species, can defend themselves with stings, sharp spines, or bites when they feel threatened. Interacting with these creatures increases the likelihood of injury, which can have serious consequences while diving.

Additionally, many marine species are crucial to their ecosystems and can be harmed by human contact. Protecting marine life helps maintain the balance within the ecosystem, which is essential for the overall health of ocean environments.

While personal hygiene, visibility, and entanglement in fishing lines are valid concerns in diving, they do not directly address the specific dangers posed by interacting with marine animals on wrecks, making the prevention of injuries from stings or bites the most pertinent reason for avoiding such interactions.
