Narration: The weather cleared up, but there was a new problem .
Richard: A big tiger shark came in.
From your perspective, I think you could see him more clearly than I.
It was so poor visibility down there that I could just make it out,
but I could see it was a pretty big one.
Mark: Visibility's gone down to about five feet.
That's just not safe enough to dive with these big tiger sharks.
So we're gonna have to call off the dive team. Very disappointing.
Narration: The poor underwater visibility didn't seem to stop the sharks
from finding their prey, giving John some concerns .
John: I've got very mixed feeling about this,
because I don't really want to see the albatrosses eaten,
but that's what I'm here to film.
You can't help wishing the albatrosses will get away each time.
I sort of cheer inside when they do. There's a shark, right in the shallows!
Narration: John continued to film the action.
But it was another three days
before the visibility cleared sufficiently to make diving safe again.
After days of practice,
Richard was finally getting to the birds ahead of the sharks,
yet, still no success .
Woman: What did you see?
Richard: The albatross gave us the run-around for a while,
and then he finally decided he'd had enough of us and flew away.
Narration: But why didn't the sharks take the bird?
Were they now avoiding the divers ?
Doug: Whatever senses they're using,
they've shown us that they want to stay away from us.
Narration: Over the next two days,
Doug's theory was confirmed,
and Richard realised he had little to fear.
Richard: The sharks are not interested in us.
They're only interested in a slightly oilier substance
in the form of a nice, fat, juicy albatross.
