It’s happened to me dozens of times: I’m riding a wave when, out of the corner of my eye, I see a black shape coming up beneath me. Being in Cape Town – a great white shark hotspot – it’s hard not to assume the worst. But fear soon gives into relief when it becomes clear that I’m sharing the wave with a Cape fur seal. Sometimes, they get so close you can see the bubbles on their whiskers.
Now, nine seals have tested positive for rabies – the world’s first significant outbreak of the disease in marine mammals – and people like me are watching the water along this 400-mile (600km) coastline for a different reason.
