But it's more than likely they would spit you back out. To avoid a shark attack, you can also learn how to not be shark bait by avoiding swimming if you're bleeding or lying on a surfboard. Sharks commonly go after seals, and from below, a surfboard can look like a seal. You can also avoid spear fishing, because skewering fish sends out electric signals that can attract sharks.
In the unlikely event that you are attacked by a shark, experts say it's best to fight back. Chapman recommends going for its eyes or gills if possible. If you can give yourself a sense of control, you feel like you're in less danger. Chapman says that yes, the number of shark attacks per year is increasing, but this isn't in line with the skyrocketing human population. Of the odd shark attacks that happen each year , fatality rates are decreasing thanks to improving medicine and medical response time.
It's difficult to count sharks, Chapman says, but it appears their numbers are decreasing. To meet the demand for shark fin soup , some fishermen in Asia will catch sharks, chop off their fins, and then release them back into the water to die. Sharks are also unintentionally caught as bycatch. The animals are important to oceanic food chains, and sharks keep ecosystems in line.
Studies have shown that shark populations can have an effect on sea grass composition and the presence of other animals in a habitat.

Sharks generally avoid humans and only interact out of curiosity, in defense when we threaten them or invade their territory, or if they confuse humans for their normal prey, which varies from fish to marine mammals to seabirds, depending on the species.
But no matter the reason, shark interactions with humans are extremely rare occurrences. Shark bite fatalities, while terrifying fuel for the imagination, only occur about six times per year. As predators, sharks are critically important to maintaining healthy marine ecosystems. Predators keep populations of prey species strong by feeding on the weak and the sick, and they keep prey populations in check which maintains a healthy balance. Many sharks are important prey for other wildlife from marine mammals, seabirds, and other fish including other sharks.
Healthy oceans directly benefit humans. Sadly, many species of shark in American waters are endangered or threatened due to human activities. Overfishing threatens shark populations both by directly catching sharks and by depleting their food sources. Over 90 percent of the global warming that has happened over the past fifty years has occurred in the ocean. And as temperatures are rising, the acidity of the ocean is increasing from excess carbon dioxide, while the amount of dissolved oxygen is decreasing.
In some areas, climate change is even changing the salinity levels of the water. While it is challenging to predict exactly how these impacts will affect highly mobile species like sharks, they will certainly impact the ecosystems many shark species depend on.
Many shark conservation efforts are underway in the U. Bader and his colleagues study fear — specifically, they investigate what kinds of crimes Americans fear most.
The researchers have found that the more familiar a person is with the risk of becoming a victim of a certain crime, the less likely that individual is to fear it. While Bader hasn't specifically studied peoples' attitudes about sharks, he said he thinks the same trend is likely true for shark attacks. In other words, the more familiar you are with your risk of being a victim of a shark attack , the less likely you are to fear such an attack.
But most Americans have a skewed perception of how likely they are to be victims of any kind of crime. And the average American's perception of how likely he or she is to be the victim of a shark attack could be similarly skewed, according to Bader.
And why their fears are much lower in terms of things that they're more likely to experience," Bader told Live Science. Last year, Bader and his colleagues conducted an Internet survey in which they asked Americans to divulge how fearful they felt about specific things the survey didn't include sharks. The results showed that people who reported watching television regularly, including news and crime shows, were more likely than people who didn't watch these programs to think that the rates of certain crimes — such as serial killings, mass shootings and child abductions — had gone up over the past 20 years.
In reality, the rates of all these crimes in the United States have declined in the past two decades, Bader said. But people don't tend to perceive it that way," Bader said. Like they do with crime, people get most of their information about sharks from the media, which can be a problem, said Bader. He added that when one shark attack occurs, media outlets tend to seize the opportunity to report on other examples of such attacks. This heightened coverage can give people the impression that the rate of shark attacks is on the rise, even though it might not be.
To do this, you can read up on what kinds of sharks live in the water you're about to swim in , or learn about which species of shark have been known to go after humans. Pro tip: blacktip and spinner sharks sometimes mistake humans for prey.
If you swim in clear water, you can give yourself the illusion of being in control if you did spot a shark. Great whites can reach speeds 10 times faster than typical humans , so logically, if one of these sharks were to come toward you, you wouldn't have time to escape it. But it's more than likely they would spit you back out.
