Well only having about 60 dives, its still a scary thing for me any encounter with them. When I was younger and working on the docks and boats in Cape May, NJ, I have some run ins with Macko and Tigers on a constant bases. And I have seen some pretty bad things on the boats with them. Diving in Port St. Lucie and Jupiter Beach, I see Bulls a little more then I would like to, thats for sure. And the part I hate the most, is the other few divers I dive with in Port St. Lucie and Jupiter, is they are all die hard spear fishers. I always tell them, "you go over there and I will stay over here. I will admit I respect these animals, and I give them there space. There is a reason they have been around for millions of years, because they are good at what they do! I think my top terrible's are 1. Tiger shark - they would eat a trash can if they could, they are the dumpster divers of the shark world, and there size can be just insane. 2. Bull shark - They adore shallow water, aggressive in nature, and can even survive in fresh water, which would all explain why they are responsible for the most attacks. 3. The Great White - Would be number 1, but the chances of them in my regional dive area is not all that great. 4. Mako - becuase by the time you see them, its usually to late, as fast as they are. The one thing, they prefer deep water. There are plenty of others that can cause you problems like Lemons, Blues, Reef sharks, etc. But I think due to there size, I don't feel as intimaded. But as I mentioned earler, I still give them the utmost respect.
As far as, shark dives, not a real big fan of them. I just think these dives aclimate the sharks to humans, and if the guide is feeding them, its just a receipt for disaster. But thats just my two cents. Kinda like walking through the African plains with a piece of beef in your pocket, if you catch me. I have been seeing enough bulls, that I was considering getting the Shark Shield, because of my fellow divers addiction to spear fishing. You know the old proverb, "Better to be safe then sorry".
