Why Do Sharks Attack?


  • Mistaken identity is often believed to be the cause of most attacks.
  • They could be thinking a surfer is a seal or a sea lion, but their vision has been proven to be quite well.
  • The majority of shark attacks is seen as gentle affairs so if it was a mistake of identity, then it would have been much more aggressive.
  • Meaning that most attacks are probably their way of investigating.
  • Since they do not have hands, they must use their mouth, which causes the "attacks" on accident.

How To Avoid Attacks.


  1. Always swim in a group. Sharks most often attack lone individuals.
  2. Don't wander too far from shore. Doing so isolates you and places you away from assistance.
  3. Avoid the water at night, dawn, or dusk. Many sharks are most active at these times and are better able to find you than you are to see them.
  4. Don't enter the water if bleeding. Sharks can smell and taste blood, and trace it back to its source.
  5. Don't wear shiny jewelry. The reflected light looks like shining fish scales.
  6. Don't go into waters containing sewage. Sewage attracts bait fishes, which in turn attract sharks.
  7. Avoid waters being fished and those with lots of bait fishes. Diving seabirds are good indicators of such activities.
  8. Don't enter the water if sharks are present. Leave immediately if sharks are seen.
  9. Avoid an uneven tan and brightly colored clothing. Sharks see contrast particularly well, so use extra caution when waters are cloudy.
  10. Don't splash a lot. Also, keep pets out of the water. Erratic movements can attract sharks.
  11. Use care near sandbars or steep drop-offs. These are favorite hangouts for sharks.
  12. Don't relax just because porpoises are nearby. Sightings of porpoises do not indicate the absence of sharks. Both often eat the same foods.
  13. Don't try to touch a shark if you see one!
  14. If attacked by a shark, the general rule is "Do whatever it takes to get away!" Some people have successfully chosen to be aggressive, others passive. Some yelled underwater, others blew bubbles. I personally would go down fighting.
