Okay, so this is probably not a problem you run into in your daily life. I’m an avid surfer and in my 18 years of experience, I have only seen TWO sharks! Neither of them bothered me. The First here are few tips of how to avoid getting into this predicamant in the first place
1) Don’t swim with your dog. The movement of a dog in water sends vibrations for very long distances that attract sharks. Contrary to popular belief, vibration attracts sharks more than blood. For the same reason, you also don’t want to splash around in the water.
2) Don’t swim in murky water, especially right after it rains. Most attacks happen because a shark is trying to figure out what you are. Murky water makes it more difficult for them to see you.
3) Don’t swim at the mouth of a river where it reaches the ocean. Bull sharks swim in rivers hundreds of miles away from the ocean. They can travel in extremely shallow water and they are not a friendly species.
4) Don’t wear shiny jewelry in the water. It will attract their attention and perhaps make them want to find out what it is.
5) Don’t swim alone. Sharks are lazy preditors so they want to pick off the weakest link. If you are in a group they are less likely to think you are easy prey.
