Christian Miller shot this stunning image of a green turtle (Chelonia mydas) at the turtle sanctuary where he works and posted it onto the Wetpixel Facebook Group. At the Save our Sea Turtles the turtles are fed on squid.
The sanctuary and hence the image were shot on Fitzroy Island, Queensland, Australia. Christian was using a Nikon D90 in an Aquatica housing with two Ikelite DS161. Camera settings were 1/250 at f13. ISO 500.
