Shark attacks are rare, and almost never deadly

The real-life likelihood that you’ll have a close encounter with a shark is about 1 in 11.5 million, according to the International Shark Attack File. In fact, you’re more likely to be injured in a boating accident or bike wreck than you are in a shark attack. More good news: death by shark hardly ever happens. In 2019, for example, there were only five fatal shark attacks. These are the tips that could save your life in the event of a shark attack.

Punching a shark may not be your best defense

Nosal of the Scripps Institutions of Oceanography the New York Times. Here’s what happened when this surfer punched a shark to try to save his friend.

Most shark attacks are on men

According to Nat Geo Wild, 93 percent of shark attacks from 1580 to 2010 were on boys or men. The explanation comes down to numbers: More men than women surf, boogie board, and SCUBA dive—all sports that come with a risk of attack. Find out if sharks can really smell blood.

Just like us, sharks eat breakfast and dinner

Sharks don’t attack on purpose


But they sometimes mistake humans for food in murky water. Imagine the white flashes of the underside of a person’s feet as they are kicking through the water or the sparkle of jewelry on ankles or wrists. “A shark may confuse it with its natural prey,” John Carlson, a research biologist at the Southeast Fisheries Science Center, told the New York Times. Reduce your (already slim) chances of a shark encounter by leaving your jewelry on the beach. Here are some more reasons sharks are actually misunderstood.

The world’s shark population is decreasing

Lest you think the ocean is “teeming” with sharks: “The shark population in the U.S. and around the world are at perhaps all-time lows,” George Burgess, director of the International Shark Attack File at the Florida Museum of Natural History, told NPR. “On the other hand, the human population continues to rise every year. Fundamentally, the number of shark attacks every year is driven by the number of people in the water, not the number of sharks.”

You can track sharks online

Scientists and conservationists tag a small population of sharks, usually with dart guns or through slightly more dangerous methods, to gather information on their migratory patterns, size, and growth. Using that data, tracking the animals online has also become somewhat of a hobby for some beachgoers, who can follow tiger sharks in and around Hawaii and several shark species in Western Australia and in much of the northern hemisphere. One popular great white named Mary Lee has more than 128,000 followers on Twitter.

Sharks follow the (non-human) food


Scientists have reported high numbers of herring and sea turtles in the Outer Banks of North Carolina, which may have explained the unusually high number of shark attacks in that area in recent years. Find out the animals that are deadlier than sharks.
