When you have been in the water long enough sharks are a natural encounter. After a while they just become part of the landscape to you. They are attracted to the struggling fish and will try to bully you for your fish but rarely are you their main attraction. When you realize that they are a lot like dogs is when your attitude starts to change with about them being around. You realize if you stand your ground give them a nudge with your spear, they generally loose interest really quickly. They avoid fighting for or with their meal. They always say it is the shark that you don't see that will get you and it is true. As long as your keep them in your sight, and confront them they will loose interest. I am no more afraid of a shark nowadays than I am a dog. You give them respect but you stand firm. I have only ever been in one really hairy situation and that was with a persistent 14 ft Tiger shark. Long story short after several nudges with my spear, and it just circling back around, I used what we call a blowfish defense on it, where you ball up and as they are coming in you stretch out your body, arms and legs quickly. That was enough to startle it and cause it to loose interest. That was the first and last time I have ever had to blowfish, All of the rest where easily persuaded that I was going to fight for my meal.
