Shark attacks make headlines in the news. What are the facts behind shark attacks in Hawaii, and what can you do to reduce the risk of being attacked?

The December 2, 2013 news of a second 2013 fatality due to a shark attack has, unfortunately, once again brought attention to shark attacks across the globe and in Hawaii.

News of shark attacks tend to make headlines in many major newspapers and in the broadcast media. Any negative publicity is a concern to Hawaii's tourist industry, which is so dependent on visitors for its economic health. Let's take a brief look at the facts about shark attacks in Hawaii and learn what you can do to reduce the risk of being attacked.

Question: What is the likelihood of being attacked by a shark in the waters of Hawaii?
Answer: Very unlikely. In 2012, 7.99 million visitors came to the islands and there were just ten shark attacks in Hawaii (the highest since 2002). In 2008 there were only two attacks and just three attacks each year in 2009, 2010 and 2011. So far in 2013, there have been thirteen attacks with eight off of Maui. Unfortunately, the victim an August 2013 attack off of Maui died in the days following the attack, as did the victim of December 2013. Prior to those attacks, the last fatal shark attack in Hawaii occurred in April 2004.

Question: Are the number of shark attacks increasing?
Answer: Not really. Since 1990 the recorded number of shark attacks has ranged from one to twelve. Since World War II, the number of visitors to Hawaii has steadily increased each decade. More visitors means more people in the water, which increases the possibility of attacks.

Question: What is the historical data on shark attacks in Hawaii?
Answer: From 1828 to December 2013 there have been 128 total unprovoked shark attacks in Hawaii. Ten of these were fatal attacks. (source - International Shark Attack File, Florida Museum of Natural History, University of Florida)

Question: Are shark attacks the greatest risk in the waters of Hawaii?
Answer: Definitely not. Far more people die each year of drowning than are injured as a result of a shark attack. The waters of Hawaii are very unpredictable. Currents and wave heights vary from day to day. An average of 60 people die each year by drowning in the waters of Hawaii.

Question: Why do sharks attack humans?
Answer: There are several possible explanations. First, there are forty species of sharks found in the waters of Hawaii. This is their natural environment. Of these eight are commonly seen near shore, including the Sandbar, Reef Whitetip. Scalloped Hammerhead and Tiger Shark. The waters of Hawaii are home to many of the prey of various shark species, such as monk seals, sea turtles and baby humpback whales. Humans are not a natural prey of sharks. It is likely that when an attack occurs, the human is mistaken for another prey. Sharks are also attracted to waters frequented by fishing boats, which often trail fish remains and blood.

Question: What can one do to reduce the risk of being attacked by a shark?
Answer: By learning more about sharks, and using a little common sense, the risk of injury can be greatly reduced. The State of Hawaii Shark Task Force recommends the following measures to reduce the risk of being bitten by a shark:

  • Don't swim alone.
  • Swim in guarded areas.
  • Avoid swimming at dusk.
  • Don't swim with bleeding wounds.
  • Avoid murky water.
  • Don't wear bright jewelry or high contrasting colors.
  • Refrain from excessive splashing.
  • Don't swim if sharks are known to be present.
  • Be alert if turtles and fish are fleeing the area.
  • Remove speared fish from the water.
