During this holiday season thousands of people will swim in our coastal waters, but how many of us will actually encounter a shark? Have you ever wondered what the truth is behind shark attacks? If so, read on…
The International Shark Attack File (ISAF) - the global authority on shark attacks - states that there are about 70-100 shark attacks each year, 5-15 of which result in death. No-one knows the actual number of shark attacks though because many attacks go unreported, particularly in developing countries where attack statistics are difficult to obtain. We do know, however, that the number of shark attacks is quite low especially given the increasing number of shark-human interactions worldwide.
Shark attacks are divided into two categories: provoked and unprovoked attacks. Provoked attacks occur when a human initiates contact with a shark, for example: a diver is bitten when touching a shark, someone is bitten while feeding a shark, or a spearfisher is bitten while spearing fish. Unprovoked attacks are incidents that occur in a shark's natural habitat where humans do not initiate contact.
In 2006, ISAF recorded 62 unprovoked shark attacks and 16 provoked attacks on humans worldwide; of the unprovoked shark attacks, only 4 were fatal. An average of 4.3 people died from shark attacks between the years 2001-2006, and the majority of both fatal and non-fatal attacks occurred in North America. Florida has more shark attacks than any other region in the world.
In 2006, shark attack victims were as follows: 42% were on surfers/windsurfers, 34% on swimmers/waders, 8% on divers and snorkellers, and 2% occurred upon entry into the water. In the remaining 14% of attacks, no activity was reported.
Despite the growing human population and our growing pursuit of marine activities, ISAF says the number of shark attacks has generally levelled of since 2000. Reasons attributed to this decline include:
1) declining numbers of sharks in the oceans due to overfishing;
2) decreased usage of traditional high shark-human interaction areas, such as the Florida coast, due to economic slow-downs following 9/11 and increased storm activity in these areas;
3) increased awareness of "high-risk" areas means that humans have become better at reducing the chance of interaction with sharks.
So what should you do if you come into contact with a shark this summer? Well, if you are diving or snorkelling, take a moment to watch the shark. They are perfectly designed for their aquatic environment and watching them is like watching moving art. However, if you happen to be approached aggressively or attacked, ISAF recommends taking a proactive response by doing one (or all) of the following:
1. Shark's noses are the most sensitive part of their body, so they are likely to postpone an attack if you hit it on the nose with a hard and/or heavy object. Get out of the water as soon as you can.
2. If the shark comes close enough, or initiates an attack, claw its eyes and gills; these are the second most sensitive parts of a shark.
Perhaps the most important thing to know is that, like all apex predators, sharks are the kings of their watery jungle. Like all jungle kings, sharks respect power and size, so never act passively when a shark swims over to check you out.
Did you know more fatalities in the US are caused by deer than by sharks, and that you are 100 times more likely to be injured by paint products than you are to be attacked by a shark? Listed below are some interesting facts on the likelihood of being fatally attacked by a shark. If you are interested in finding out more fascinating facts about shark attacks, check out the ISAF website.
In South Africa we are blessed with a long coastline, beautiful beaches and some of the most diverse shark species in the world. Every year, thousands of tourists and holiday-makers congregate on these beaches and swim in the waters. But it is the truly rare and exceptional occasion that one actually encounters a shark, and it is even rarer to be attacked by one. For all the negative media hype and portrayal of South African sharks, only 4 people were attacked by sharks in 2006. This pales in comparison to the millions of sharks that are killed by us each year for food and medicinal purposes. Rethink the shark? Yes, we think so.
