Diver captures inside of curious sea turtle's mouth

This big green turtle is very relaxed when approached by divers. It stares curiously at the camera and then decides to nibble it, giving a very close up view of the inside of its mouth, tonsils and all. The turtle takes several bites at the camera before turning away. If approached slowly, a turtle such like this one will often close its eyes for a nap while a diver takes pictures or quietly observes. Some will even inch towards the diver curiously!
