On one side, roughly 60,000 brown fur seals haul out on Geyser Island's rocks, their barking audible from the mainland eight kilometers away. On the other side, Dyer Island shelters a declining colony of African penguins. In the water between them, great white sharks patrol with the patience of predators that know their prey must eventually swim home. It is one of the most concentrated predator-prey theaters on earth, playing out daily on a pair of windswept islands that together barely cover a few hectares.
