The sand tiger shark lives worldwide near the seafloor in surf zones, shallow bays and coral and rocky reefs. They are a large species, growing to a maximum length of feet ( m) and weight of pounds ( kg). 2 The sand tiger shark is the only shark that is known to maintain neutral buoyancy by gulping air at the water’s surface and holding it in its stomach. Jul 02, · Sleek, muscular bodies of sharks slice through the water—powerful predators of the ocean, larger shark species—white, tiger, and bull sharks—were implicated in the reported incidents. The question betrays a lack of understanding of predators and prey. When prey is scarce, predators starve. No predator species can survive, long term, by consuming it’s prey to the point there aren’t plenty of prey animals around to reproduce and.
Sleek, muscular bodies of sharks slice through the water—powerful predators of the ocean, striking fear in smaller fish—and sometimes humans. Spoiler: though the overall long-term trend shows an increasing number of shark attacks, the number has actually declined in the past few years.
Still, a notable difference exists in the number of recent incidents on the U. Atlantic coast versus the Pacific. The reasons may surprise you. The group has documented 6, accounts of shark-human incidents, including historical accounts going back all the way to the s. Though ISAF reports on incidents across the globe, Tyler Bowling , the program manager, says people are much less likely to report a shark attack from a smaller country with limited phone and Internet access, or if they are engaging in risky behavior when the attack occurs.
ISAF focuses on the number of unprovoked attacks, reporting that the overall trend has increased worldwide over recent decades. The main reason, the scientists say: tourism. The human population is increasing, while more people are visiting beaches and engaging in water activities.
Bowling suggests that popular perception of an increase in shark attacks may stem more from news bias and the ebb and flow of the news cycle than the actual numbers of attacks. The recent spate of attacks in June in North Carolina were earlier in the year than usual, which can cause panic, Naylor added. Within the continental United States, more shark-human incidents occurred in the Atlantic Ocean—only four attacks were reported in the Pacific three from Hawaii compared to 27 in the Atlantic.
The reasons for the difference may be complicated, but Naylor said it is most likely due to the prevalence of shark species on the two coasts, and the strength and body sizes of those species. In the Pacific, larger shark species—white, tiger, and bull sharks—were implicated in the reported incidents. In Hawaii, attacks by tiger sharks are the most common, whereas in California, white sharks also known as great white and white pointer are most likely to be involved.
Globally, these species are involved in the majority of fatal attacks, contributing to their negative reputation in the media. These species tend to be territorial and if they do attack people, they may be sending a warning: get out of my space. Smaller shark species contribute more attacks to the Atlantic Ocean tally. Currents in the Atlantic Ocean , like the Gulf Stream , can push warmer water closer to shore—with bait fish. These bait fish attract sharks, like blacktips, closer to shore.
Blacktip sharks have bitten 28 people since the s the majority in Florida , though all but one have resulted in relatively minor, and non-fatal, bites.
The one exception to the Atlantic trend, says Naylor, is Massachusetts, where a few more attacks popped up in the last few years as the white shark population has rebounded since the Marine Mammal Protection Act in brought back their prey—seals.
Another factor in the distribution of shark incidents may be water temperature. Catherine Macdonald , a shark expert and director of the Field School in Miami, Florida, says more attacks do tend to occur in warmer waters, because more people spend more time playing or swimming in those waters, increasing the chances of bumping into a shark.
Most victims of attacks are swimmers or surfers. Even so, in recent years, the raw numbers of shark attacks—especially fatal attacks—have been on the decline. People reported only 66 unprovoked attacks in , down from a peak of 98 in Worldwide, 49 shark attacks have been reported—a pretty standard year, Naylor adds.
But they can get confused. If they are chasing after smaller fish, and a person is standing or swimming among the school, a confused shark may bite human flesh. Bowling notes that the shark is often just as freaked out as the human in any encounters, not being used to a human being in its environment.
