On Benares shoal, northwest of Peros Banhos, 1978.  We entered to find scores of sharks, mainly white and black tips.  Taken in mid water, this photo (taken with a standard 35 mm lens) shows a dozen.  This density existed all around us, above and below, one person counting 'nearly 100'.  He may have exaggerated, but we did little work that dive.  They were not agitated or in any way aggressive towards the divers.
