You're attacked by a shark
Sharks attack when they mistake the movements of humans for those of their natural prey, according to the Florida Museum of Natural History. Most attacks occur in waters near shore and sharks are more likely to go after lone swimmers than people in groups. If you are injured, your blood may attract other sharks.
Fight the shark off in any way that you can, using your hands and feet, says Hodges. Aim for the vulnerable parts of the shark, such as the eyes or gills. Get out of the water as quickly as possible.
