After 2015’s record-busting 98 shark
attacks, the 81 worldwide attacks in 2016 was back in line with the
five-year annual average (about 82 incidents). But worldwide shark
attacks still remain on a slow upward trend as our human population
grows and aquatic sports become more popular. That’s according to the Yearly Worldwide Shark Attack Summary compiled by scientists at University of Florida.
George Burgess, curator of the University of Florida’s International Shark Attack File, (ISAF) said in a statement:
A shark attack is a human phenomenon. Sharks are a natural part of the ecosystem. The ocean is a foreign environment to humans, and when we enter the sea, we’re entering a wilderness.
Four of the attacks in 2016 were fatal, a
drop from six total fatalities in 2015. The United States had no fatal
attacks in 2016, but had the most attacks globally, with 53.
South Africa had fewer incidents than
normal, with only one (non-fatal) attack. Australia, another shark
attack hotspot, had 15, including two fatalities. The French territory
of New Caledonia in the South Pacific has emerged as “an area of
concern”, according to the report, with four attacks in 2016, two of which were fatalities.
In the U.S., Florida was the state that
had the greatest number of attacks, with 32, which accounted for about
60 percent of attacks in North America and about 40 percent of the
global total. Hawaii had 10 attacks, followed by California with four,
North Carolina with three, South Carolina with two, and single attacks
in Texas and Oregon.
The database, which tracks shark attacks globally, defines
unprovoked shark attacks as those initiated by a shark in its natural
habitat. But Burgess said that many of these incidents might be more
accurately called “human-shark interactions,” since not all attacks
cause injury, and they can include a rough bump from a shark or a bite
on a surfboard.
More that half of the attacks worldwide
involved board sports – surfing, boogie boarding, and paddle boarding –
that kicking and splashing. These kinds of water disturbance can draw a
shark, Burgess said.
Sharks are attracted to irregular activity, especially with the inevitable wipeout and the big splash that follows. If you have a shark trailing, that’s often when it will strike.
Although shark attacks have gradually increased, the number of fatal
attacks has consistently fallen over the past century. Researchers
attribute the decline in fatalities to improved safety practices on
beaches, better medical treatment, and growing public awareness of how
to avoid potentially dangerous situations.
While the chances of being injured or killed by a shark are “infinitesimal,” Burgess says, the ISAF offers recommendations for how to lower your risk of a shark attack or fend off an attacking shark.
According to a statement from University of Florida:
While the human population is skyrocketing, many shark species are on the decline. Threatened by over fishing and loss of habitat, sharks’ complex life history makes it difficult for them to rebound quickly. As major predators, their numbers are inherently low compared with other smaller marine species, and their slow sexual maturation process, year-long pregnancies and long lifespans compound the obstacles to rebuilding populations.
Bottom line: In 2016, the number of global
shark attacks worldwide dropped 81, after 2015’s record-busting 98
shark attacks, back in line with the five-year annual average. But
worldwide shark attacks still remain on a slow upward trend.
