I've done my share of diving/fishing off florida, my biggest pants crapper was running into a barracuda off south florida around a wreck (years ago, think it was one my 4 training dives before being an expert)
Think the fear factor set in when I seen it swim straight at me, having the razor teeth I've seen the damage they cause, I rarely went diving after this, mainly to clean the bottom of my boat and that's it.
