No one can blame you if you spot a shark in the water and decide to swim the opposite direction as fast as they could. However, if you’re a documentary specialist, especially for sharks, then you will want to come closer and see them in full action.
Unfortunately, these two aren’t shark documentarists or behavioral analysts. They’re just divers who have more gall than the usual tourist. When they met the shark, they didn’t flinch, but the shark was clearly uninterested in the two divers. They showed the shark with respect and interacted with it in the most non-aggressive way as they can possibly muster.
Never try this without an experienced tour guide. Seriously.
