Don't know if its fake or not, but holy carp...
Following text quoted from email.
Family on holiday in Australia for a week and a half when husband,wife and
their 15 year old son decided to go scuba diving. The husband is in the navy
and has had some scuba experience.
His son wanted a pic of his mom and dad in all their gear so got the
underwater camera on the go. When it came to taking the pic the dad realized
that the son look like he was panicking as he took it and gave the "OK" hand
sign to see if he was alright.
The son took the pic and swam to the surface and back to the boat as quick as
he could so the mom and dad followed to see if he was OK. When they got back
to him he was scrambling onto the boat
When the parents asked why, he said "there was a big shark behind you" and the
dad thought he was joking. But the skipper of the boat said it was true and
that they wouldn't believe him if he told them what size it was.
As soon as they got back to the hotel they put the picture onto the laptop and
this is what they saw.
Try and tell me you wouldn't have emptied your entire digestive system right
at the point you saw it and would you have stayed to take the picture??
