Have you seen how many attempted shark attacks are online? Videos, newspaper headlines, photographs (often even photomontages). With all this hype about potential dangers, one might think that we divers are all daring hotheads!
For the sake of truth, the context must be clarified immediately. As is often the case, newspapers, social media, and individual users transform simple news or images into sensational scoops, irrationally exaggerating events that have rational explanations.

Unlike Australia and the United States, where fatal shark attacks are more frequent, in other countries they occur roughly once a decade. Moreover, those attacked are almost never divers but mainly swimmers, surfers, or snorkelers. In addition, a scientific study by American Alissa Scharfer in the Caribbean shows that the greatest danger occurs in areas where shark‑feeding is practiced, during moments when that activity is not underway (perhaps the shark thinks: "You invite me to lunch and leave nothing to eat? Then I'll try one of these unappetizing creatures swimming at the surface"). Remember that in most parts of the world, shark‑feeding is rightly illegal today as it alters these predators' behavior and increases the risk of attacks.

It is said from memory that the last attack on a diver with scuba tanks in the Red Sea dates back to 2004, but in that case the victim was a diver cleaning encrustations off the jetty at Sharm el Sheikh, in conditions of locally limited visibility and with "food" odors dispersed in the water.
In these waters, for example, dangerous species include the oceanic whitetip (Carcharhinus longimanus) and the shortfin mako (Isurus oxyrinchus). Although "dangerous," these species very rarely attack humans and usually do not approach the shore. In fact, oceanic whitetips in Egypt are among the most sought-after encounters by divers on the vertical walls of reefs, such as Elphinstone, Daedalus, or the Brothers. They frequently swim among boats because cooks often throw food scraps into the water, offering divers the "joy" of a close encounter—albeit as a result of altered behavior.

Finally, due to the intensive fishing of their usual prey, such as tunas (in Egypt and elsewhere), oceanic sharks now find little "traditional" food.
In summary, shark attacks on divers are very rare, but one shouldn’t be surprised if they intensify; any increase would largely be due to human-induced behavioral changes… even when wearing wetsuits and fins!
