Forget bungee jumping and whitewater rafting ... this is real adventure holidaying.
Not just getting to within centimetres of a great white shark, but putting one hand inside its jaws ... and being able to take it out again.
The diver who took these pictures was thrilled when a huge shark nosed up to his underwater shark-watching cage, and even more thrilled at the photo opportunity that followed.
Wildlife photographer Don Carpenter was with divers in cages at a depth of 10m near Guadeloupe Island in Mexico when the great white swam by.
"When you're practically touching the nose of a great white you're thinking two things - how fast can I get back into the cage and will it hurt when she rips my torso off and leaves my legs there."
