Dad, wife, bro, son and I went to the beach yesterday. We were further south about a mile down from the public beach on a friends private area and there was about ten to fifteen people around us. Beautiful day, crystal blue water. Swimming for about an hour and then got out. Dad and wife stayed in. Few mins later I'm sitting down glassing the horizon as I usually do. It's the beach, never know what you'll see? So I'm sitting there watching dad and wife laze around talking and a few seconds later a little voice in my head is screaming! By the time I noticed them they had already swam north past both of them about ten feet away. Then it clicked 'holy crap those are big!' I jumped up and calmly but loudly said 'out of the water!' wife and and dad were like 'duh? Huh?' I repeated louder this time as I was myself going out into water to get both of them 'OUT OF THE WATER!!!' then it clicked. Like A Formula 1 Jesus my wife was gone but poor old dad was just chugging along. Meantime these large dark shapes had turned on him and were slowly approaching. The glasses I wear cut right thru the water and allow me to see things the normal eye or glasses can't see. I grabbed dads arm and pulled him out of the four foot deep water he was still in. We all got back out and turned and looked and there they were just cruising slowly in typical S pattern along the shore. Nobody could really see them until we started passing my glasses around and then everyone was like 'oh my!'. A lady and her boyfriend, French tourists tried them on and didn't go back in after seeing them. So we followed them down the beach for quite a ways as it was still unclear as to what they were. Then in a little wave all of them shot after some bait fish and broke the surface. We saw their dorsals and tails break and flop over. Large very large clear flexible fins. These were not sharks, they were a small pod of Tarpon. Smallest one was around three feet and larger ones were at least 4-6 feet long. These are large 1-200lb fish that look like a huge bass. Until you know you dont know but it's best to just 'GET OUT OF THE WATER!'
