In my opinion, apex predators are very interesting.  From what I have observed they are curious and will investigate what they think might be food.  If there is food in the water they will take an easy meal.  

Sharks unlike people do not have hands which might otherwise allow them to tactically check out potential meals.   So what do they do, they taste potential entres with their mouths.  Now that might seem bad, it can have a bad effect on anyone the shark chooses to sample.  

So I keep thinking they sure are interesting but I ill try to avoid becoming a meal,
