Shark attacks or accidents?
  • Some great tips on how to get bitten by a shark:
    • Swim or dive alone in turbid or murky water, preferably at night and when bait fish are present
    • Surf, swim or dive near colonies of seals or other marine mammals that large predatory sharks like to prey on
    • Catch or harass sharks and always pull the nurse shark's tail
    • Cut yourself or smear fish blood on you
    • Ignore warning signs and don't use protected beaches
