I have been traveling to Seal Island off the coast of South Africa for 5 or 6 years now to photograph the interaction between the great white sharks and their prey, the cape fur seal. On the morning of July 26, 2013, I made my way out to Seal Island with a local shark tour operator. The sea was not too rough and there was some cloud cover -- good conditions to see the sharks hunting.

Usually, the most active hunting time is an hour before sunrise and an hour after. I arrived at the island at about 7:15 and immediately we could see that there had been some kills -- from the gulls in the area hovering and the slicks on the water. When the attacks happen they are at lightening speed and can be over in a second. We decided to track alongside some seals which were coming back to the island after feeding out at sea, keeping a distance so as not to interfere. I noticed a smaller seal had dropped off the back of the main group. The sharks often choose the single seals to attack as their chance of success is higher.

I tracked with the seal in my viewfinder and, without warning, a great white attacked. The shark had its mouth wide open and the seal managed to just avoid the bite. It was sent flying out of the water by the nose of the shark. As the seal was falling back towards the water it narrowly missed the mouth of the shark. For the next couple of minutes the seal stayed close to the shark's body but away from the mouth, using its agility to tire out the shark. When the shark gave up, the seal managed to make its way back to the island safely.
