Green sea turtle stops to get a clean from a shoal of fish

Photographer Mike Roberts, 60, snapped the incredible picture while diving at Puako in Hawaii.

He said: 'The turtle is visiting a cleaning station of yellow tangs.

'This is a very common occurrence - the tangs hang out in the same area everyday and the turtles take turns floating mid water allowing the fish to work on all areas of his body.

'In this symbiotic relationship, the tangs eat by cleaning algae from the turtle.
