Dolphin attacking Mackerel Image

British photographer Christopher Swann took these amazing shots of dolphins and sharks preying on mackerel of the coast of Azores. 

The frightened mackerel swarm into these giant glistening balls in order to protect themselves from the impending attack. 

In the end, the predators win out over the 30-foot wide ball of prey.
