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:
1 Don't swim alone.
2 Swim in guarded areas.
3 Avoid swimming at dusk.
4 Don't swim with bleeding wounds.
5 Avoid murky water.
6 Don't wear bright jewelry or high contrasting colors.
7 Refrain from excessive splashing.
8 Don't swim if sharks are known to be present.
