When I was Tarpon fishing, my guide went off about how evil sharks are. He'd seen a lot of gamefish taken by sharks while he or a client were reeling them in or about to boat them. My son sided with this view and agreed that sharks are to blame until I later explained the following:
"He put the fish in that situation. The fish has no escape. The fish is trapped at the end of the line. The shark is only taking advantage of the situation they created." With this different perspective, my son said, "Hmmm. I guess you're right."
I know I'm right.
Now for the video below: Pretty dramatic. Cool slow-mo at the end. More than likely a Bull Shark. They like to hang out in marshes and estuaries. A powerful animal once again taking advantage of an opportunity. What do we expect? They're sharks!
