This is like the best part of Finding Nemo but real.
The WWF in Australia fitted a small GoPro camera to a turtle "to better understand the post-release behaviour of tagged green turtles" and raise awareness for the Great Barrier Reef which is home to 6,000 species and being increasingly polluted.
As you'll see, the GoPro doesn't stay in place long, but it does provide a hell of a show while it does.
