"This picture was taken off south-eastern Spain at a depth of 36 metres. The spotted ray is common in deeper areas here but quite rare in shallower water. I came across a dozen of them while looking for razorfish to photograph. Resurfacing to change my camera lens, I prayed that the rays would still be there when I dived back. I struck lucky. After swimming for ages below several of them - and wasting nearly all my film looking for this ventral view - I had to do several decompression stops on the way back to the surface. But I got the shot I wanted of the mouth."
