My moment with this gentle giant was fleeting, no more than 30 seconds, but wow what a wonderful moment it was.

When finally it swam into the distance, visibility, light and turbidity were not kind to the camera. All colour and definition were gone, but still the grace with which it swam was mesmerising.

This was my last glimpse before it disappeared into the depths below but not before it showed that unmistakable shark profile that evolution has not changed in millions of years.
