Turtle and a dressing of Tropical Fish

I saw the damnedest thing today, 3 Dorado in a frenzy around a Turtle. I could not get it in my head that the Dorada were trying to eat a 2 foot(ish) Turtle, Then on closer inspection they were after small fish that were sticking close to the Turtle. That close in fact, that 3 of them took shelter on the Turtles back!

Apologies that it is not the sharpest image in the world, but still worth going big with the magnifyer.

The Sun was getting low and with the polarizing filter on I was already pushing the ISO to 1600. If we are still in the same area tomorrow, I will see if we still have them around as in addition to the Adults there were scores of wee (1-2foot youngsters all staying in the shade of the ship then darting out when ever anything interesting came near, then they would all dart out make the water boils as they fought and chased small flying fish or tore apart a lump of seaweed in search of fish
