In the Bahamas, most islands have dive operations. Most of those outfits offer daily shark dives. The large sharks pass within touching distance of the divers. Intent on the easy meal, they have no interest in the neoprene-clad voyeurs. Heart beats increase.
Sharks consider humans too bony and lean to make a good meal.
Bloody fish bits are much better and, with the shark feed dives, the food is plentiful and already precut. Reef sharks by and large won't dine on humans. With that in mind, operators of dive encounters with Great White Shark provide underwater protection for paying customers and staff alike. Four-person steel cages are lowered into the water and the divers climb inside to await the arrival of the Great White. Naturalists don't like shark feedings.
