As a break from underwater photos of turtles I wanted to remind you all that, when by a warm water sea, you don't have to get wet to see them
The photos above and below were both taken from around 300 foot above the turtle in question using the bigma. As you can see they stand out remarkably well in clear tropical waters.
Turtles, like all reptiles (and for that matter all marine mammals), have to surface sooner or later to breathe so if you think you see one keep an eye on the area in question and you may well get another look. Swimming with them is more fun of course but any day I see one of these remarkable creatures is a good day.
