When encountering a shark while diving, remaining calm and avoiding sudden movements is the best approach. Sharks, like many marine animals, often respond to erratic behavior. By staying calm, you reduce the likelihood of provoking the shark or triggering a defensive response. Smooth, controlled movements help maintain the situation and allow you to assess the shark's behavior more effectively.

This reaction is rooted in an understanding of shark behavior; many species are naturally curious but typically not aggressive toward humans. By maintaining a composed demeanor, you can observe the shark safely and, if necessary, position yourself to safely exit the water without escalating the encounter.

Other options might provoke a negative outcome. For instance, swimming away quickly can instill a sense of fear in the shark, potentially prompting it to follow. Taking pictures, while it may sound appealing to some, can distract you from keeping an eye on the shark's movements and could lead to unsafe situations. Making loud noises is ineffective and could agitate the shark or cause it to react unpredictably. Thus, the recommended behavior is to remain calm and avoid making sudden movements.
