What's a trip to Hawaii without a stop in Oahu or Maui? Two-thirds of Hawaii's 159 shark attacks since 1828 have occurred off the coasts of these two islands, with 64 attacks occurring in Maui and 42 attacks in Oahu. Other islands aren't safe either, with 28 attacks occurring off Kauai and 19 off the big island of Hawaii [source: ISAF].
This total is fairly low when you consider the millions of tourists who visit each year, but you should still be on the lookout for the approximately 40 species of shark that call Hawaii home [source: Hawaii.gov]. One of these species is the dangerous tiger shark, responsible for the most attacks on humans after the great white.
Hawaii has a mixed record when it comes to dealing with sharks. On the one hand, a 1959 fatal attack led to a decades-long shark eradication program sponsored by the government [source: Gaffney]. On the other hand, some native Hawaiians call the tiger shark aumakua, or guardian spirit.
