British wildlife pho­tog­ra­ph­er Christo­pher Swann swam right in the mid­dle of this hec­tic strug­gle for exis­tence to take these pho­tos off the coast of the Azores in the Atlantic Ocean. Thou­sands of mack­erels gath­ered in a huge shim­mer­ing ball 30 feet in diam­e­ter to pro­tect them­selves from the preda­to­ry attack of dol­phins and sharks. But as they approach from deep water to shal­low water, flocks of birds of prey begin to bom­bard them from above. Attacked from all sides, mack­erels in des­per­a­tion just wait until preda­tors sat­is­fy their appetite.

Christo­pher Swann, a pro­fes­sion­al div­er and div­er, became a pho­tog­ra­ph­er and writer many years ago. He repeat­ed­ly took part in seri­ous stud­ies of the deep sea, made many inter­est­ing pho­tographs and use­ful research. Since then he has worked for the French sub­ma­rine com­pa­ny Comex as a tech­ni­cal pho­tog­ra­ph­er in the North Sea oil­fields and on the admin­is­tra­tive staff of a small inde­pen­dent oil com­pa­ny in Indone­sia. He took these pho­tographs dur­ing one of his expe­di­tions. See­ing such an action it was impos­si­ble not to start film­ing.
