The metallic glint would have been imperceptible had it not been for the sudden appearance of a large barracuda who’s sharp movements

 

and gleaming razor teeth demanded attention.  The morning sun cast a brilliant and azure spectrum on the calm water.  The barracuda

 

circled slowly into deeper water, watchful but wary.  I returned to the deep crack in the rock where the barracuda swam out of certain

 

that I had seen something, perhaps an old bottle wedged in the rock. Hundreds of small reef fish were schooling near the deep fissure in the

 

coral at about 12 feet deep: Sgt Majors, Grunts, Schoolmasters, Glassey eye.  Deeper, schools of Jacks, Yellowtail, and Chub cruised the grassy

 

beds chasing Pilchards.  The presence of the barracuda and other predators was to be expected with such a feast of plenty feeding

 

in the coral cave.  As I dove down the fish parted, darting, hundreds moving as one.  I grabbed on to the edge of the deep crack in the

 

Coral wall and peered deep into the cavern.  The water was a silky, milkey blue but to my surprise it was not dark.

 

Deep in the rock there appeared to be some strange light source. Hundreds of fish were silhouetted against an eerie

 

green glow, I could feel a warm current flowing gently out of the deep fissure and I realized that it was not

 

a crack or a cave but a tunnel. I turned over several loose limestone rocks near where I had first seen the shiny

 

object and there it was, my heart began pounding, it was not a bottle but a coin, an old coin by the look of it.

 

I was so excited that I almost dropped my brand new Niconis 6909, the top of the line underwater camera that

 

my boss had provided me with for this assignment.
